Phua et al. 2014). 2014), which became significant when the analysis was limited to self-reported frequent users (AOR 2.0, 95% CrI: 1.0, 3.9). This study contributed to the European Food Safety Agency’s (EFSA’s) 2013 decision to label neonicotinoids as potential developmental neurotoxicants and to establish an Acceptable Daily Intake (ADI) of 0.025 mg/kg/day for acetamiprid and 0.06 mg/kg/day for imidacloprid … Neonicotinoids have been detected in human urine, serum, and hair.

Although the studies in this review represent an important contribution to the literature, particularly given the lack of any general population chronic exposure studies prior to 2014, there remains a paucity of data on neonic exposure and human health. Activation and modulation of human α4β2 nicotinic acetylcholine receptors by the neonicotinoids clothianidin and imidacloprid. 2014; Simon-Delso et al. Risks of large-scale use of systemic insecticides to ecosystem functioning and services. To the authors’ knowledge, this is the first systematic review of the literature on human health effects of neonicotinoids. In the early 1980’s, Bayer CropScience began experimenting with the chemical structure of nithiazine and its effect on Neophotettix cincticeps Uhler (a grasshopper rice pest). 2014; Keil et al. Department of Environmental and Occupational Health, Milken Institute School of Public Health, George Washington University, Washington, DC, USA, Office of Health Assessment and Translation, Division of the National Toxicology Program, National Institute of Environmental Health Sciences, National Institutes of Health, Department of Health and Human Services, Durham, North Carolina, USA. Overview of the status and global strategy for neonicotinoids. To strengthen the internal validity of future studies, investigators should attempt to a) improve focus on neonics, both as a class and individually, rather than on mixtures of pesticides that include neonics; b) include drinking water and food sampling, air and household dust sampling, biomonitoring data (urine, serum), using validated biomarkers, if available, to provide a quantified, comprehensive, and environmentally relevant picture of neonic exposure; c) ensure adequate statistical power to detect associations; and d) control for potential confounders and effect modifiers, such as air pollution. (2009); however, the average age differed significantly between the severely symptomatic group versus those who were asymptomatic or had mild to moderate symptoms, reported as 67 versus 49 respectively (p = 0.008). 2009). Future studies should strive to increase the sample size, taking into account the desired statistical power, effect size, and the background prevalence of the outcome of interest (Perry 2008). 2015; Bonmatin et al. Neonicotinoid insecticides: an emerging cause of acute pesticide poisoning. Their impact is greatest on pollinators, but also on soil invertebrates and all aquatic invertebrates. Because they’re selective, they aren’t harmful to humans and other vertebrates. 2014). The largest sample, 407 cases of ASD, was stratified for a Bayesian analysis in an effort to correct for exposure misclassification and recall bias. All content is public domain unless otherwise noted. Keil et al. Imidacloprid induces neurobehavioral deficits and increases expression of glial fibrillary acidic protein in the motor cortex and hippocampus in offspring rats following in utero exposure. 2015; Yang et al. Table 3 summarizes the eight studies investigating neonics and human health included in this review, organized by type of exposure, either acute or chronic (i.e., nonacute). (2009). They also affect vertebrates, such as fish and common birds. 2015; Gu et al. 2015; Phua et al. Studies that did not meet the PECO criteria were excluded. 2015). Environmental fate and exposure; neonicotinoids and fipronil. 2014; Marfo et al. 2014). No restrictions were placed on the type of health outcome assessed. All 10 who developed severe/fatal poisoning ingested only IMI. et al. Most uses of neonicotinoid pesticides represent a risk to wild bees and honeybees, according to assessments published today by EFSA. The data were generated in part from biomonitoring (urine and nasal secretions). It is therefore not surprising that findings focused more heavily on IMI since this was the main neonic in use during the majority of study years. (2014) was based on monthly application of a flea and tick product containing IMI (Advantage and K9 Advantix, which contain ~ 9% IMI) from 3 months before conception, each trimester of pregnancy, and each year of the child’s life up to age 2. Effects of Atrazine and Neonicotinoids on the Promoter-Specific Regulation of CYP19 in H295R Cells Using atrazine as a positive control, our results confirm that this widely used herbicide is an effective inducer of aromatase via the promoters PII and I.3 in H295R cells. Of note, pesticide distribution within each polygon was assumed to be homogenous, and risks were not estimated for pesticides that had fewer than five exposed cases or controls, which could have weakened or missed associations. Again, age seemed to mediate the IMI findings. Risk of bias was assessed using guidance developed by the National Toxicology Program’s Office of Health Assessment and Translation. Significance . The neonicotinoids are highly effective insecticides with low toxicity to humans, but this unnecessary overuse is also driving the development of pest resistance against them. Environmental fate of soil applied neonicotinoid insecticides in an irrigated potato agroecosystem. 2014; Marfo et al. Neonicotinoids (also referred to as “neonics”) are insecticides derived from nicotine. Two of the developmental outcome studies focused on maternal residence proximity to agricultural use of pesticides during periconception as the exposure pathway (Carmichael et al. Both studies warned the antidotes for these pesticide classes (oximes and atropine) should not be used as treatments for neonic poisonings as they may worsen outcomes. Neonicotinoid insecticide exposures reported to six poison centers in Texas. Of the 1,142, 77% were identified as IMI alone or in combination with other neonics. (2009) used biomonitoring (blood serum) to measure the amount of IMI ingested on presentation as well as to analyze absorption and elimination rates. They’re easy to apply safely, too. How does this pesticide affect bees and other wildlife? Risk of bias (RoB) in methodology was assessed by answering up to nine questions, based on type of study. The nasal secretions were monitored for inflammatory response, which could be the result of other variables. In addition, the reference lists of relevant records were searched to capture articles that may have been missed in the database searches. Neonicotinoids are a new class of insecticides chemically related to nicotine. Environ Health Perspect 125:155–162; http://dx.doi.org/10.1289/EHP515. 2015; Krupke et al. EHP is an open-access journal published with support from the National Institute of Environmental Health Sciences, National Institutes of Health. Neonicotinoids should not pose any threat to humans if they are used according the product label and stored in places not accessible to children. In this systematic review, 89 unique references were identified (see “Neonics and Human Health: All References” in the Supplemental Material for a complete list). Ideally, future neonic-human health studies should strive to be more comprehensive in controlling for environmental and genetic factors as potential confounders or effect modifiers. The eight studies varied widely in design, but all suffered from the lack of a validated biomarker for neonic exposure. Pesticides have been associated with short- and long-term effects on human health, including elevated cancer risks and disruption of the body’s reproductive, immune, endocrine, and nervous systems, 2 as well as malignant melanoma. Cases of self-poisoning with ACE (n = 8), THX (n = 6), and CLO (n = 5) were few in comparison (Phua et al. This means that the known effects of these pesticides will decrease. (144 KB) PDF Click here for additional data file. [67]. 2014; Li et al. 2012; Gibbons et al. (2014) and Yang et al. Thirty-two neonic exposures (2.9%) resulted in “serious medical outcomes” including ocular irritation/pain, dermal irritation/pain, nausea, vomiting, oral irritation, red eye, erythema, rash, numbness, and dizziness. Small sample size can limit precision and increase the possibility of Type II (false negative) errors. 2015; USDA 2014). 2014; Krupke et al. (2009) did not report a median age or gender. humans are exposed to certain neonicotinoids – imidacloprid, for example, will be absorbed and ... fruit.8 However, in an evaluation of the effect of neonicotinoids on bee populations, authors determined that despite the decline in colonies in North America and Europe, globally managed bee colony stocks have increased by 45% in the last 50 years. (2009) suffered several assessment limitations that may have contributed to its lack of findings for IMI-related health effects. were male, 64% of the cases in Forrester (2014) were female. Three of the four acute exposure studies—two retrospective analyses of poison control center data (Forrester 2014; Phua et al. The proportion of males to females also differed among the studies: 77% of the neonic cases in Phua et al. (2009) controlled for serial correlation within each planter and exposure, the study did not report controlling for several potential external confounders, such as exposure to other pesticides, pollen, and differences in weather conditions experienced by planters. Neonicotinoids, neonics for short, are a class of synthetic pesticides used to prevent insect damage on a variety of crops. 2012; Mason et al. All four case–control studies reported an association between chronic (i.e., nonacute) neonic exposure and an adverse human health effect. 2011; Mason et al. 2014). As reviewed here, four studies reported low rates of adverse health effects from acute neonic exposure. Neonicotinoids (neonics) are a class of chemicals used as insecticides for their neurotoxic action on the nicotinic acetylcholine receptor (nAChRs). (2009) to < 70 cases (Phua et al. The available science indicates pollinator effects can result from sub-lethal exposure to neonicotinoids, but no conclusions can be drawn that actual environmental exposures from some uses are at levels that may result in effects. Immune suppression by neonicotinoid insecticides at the root of global wildlife declines. In Marfo et al. ... Nicotine poisoning in humans is rare because consuming … Specific aims included evaluating the risk of bias (internal validity) of relevant studies, determining the extent to which findings could be synthesized across studies to reach level-of-evidence conclusions (NTP 2015) for any associations reported between neonicotinoids and human health, and addressing research implications based on that evidence. Imidacloprid has got a relatively low toxicity for humans, and most people are scarcely exposed to it. due to the complexity of the information being presented. 2014; Huseth and Groves 2014; Koshlukova 2006; Krupke et al. Biochemical and microbial soil functioning after application of the insecticide imidacloprid. Eight studies investigating the human health effects of exposure to neonics were identified. 1,142 exposure cases reported to a TX poison control network from 2000 to 2012. Despite the potential for extensive human exposure, there are limited studies regarding the prevalence of neonicotinoid residues in foods sold and consumed in the United States. Of the 13 remaining, after a critical review of the full text, 5 more studies were excluded because they did not report human health effects or outcomes (Cao 2015; Craig 2005; Hou et al. Neonicotinoids, neonics for short, are a class of synthetic pesticides used to prevent insect damage on a variety of crops. 2008, 2010). They have a … 2009; Mohamed et al. 2015; Rundlöf et al. The association between neonicotinoid pesticide exposure and potential human health effects was identified as a potential candidate for systematic review. The other four studies reported associations between chronic neonic exposure and adverse developmental outcomes or a symptom cluster including neurological effects. Table 1 PECO (population, exposure, comparator, outcome) statement. Seed coating with a neonicotinoid insecticide negatively affects wild bees. Therefore, the neonicotinoids may adversely affect human health, especially the developing brain.” The bottom line is that these neonicotinoids are neurotoxins not only to insects – including bees. They are persistent in the environment, infiltrate groundwater, and have cumulative and largely irreversible effects on invertebrates. Carmichael et al. 2009). Neonicotinoids in the Canadian aquatic environment: a literature review on current use products with a focus on fate, exposure, and biological effects. In recent years, neonicotinoids and their metabolites have been successfully detected in various human biological samples. They shared similar limitations, most of which were related to case–control design. 2015). Neonicotinoid contamination of global surface waters and associated risk to aquatic invertebrates: a review. Effects of neonicotinoid pesticide exposure on human health: a systematic review. However, there are still unknown effects of these pesticides and more and more are created every day. The findings of animal studies support the biological plausibility for such associations (Abou-Donia et al. articles may not conform to 2014). A farewell to Bonferroni: the problems of low statistical power and publication bias. Sample size. 2014). 2009; Mohamed et al. Temporal proximity was determined by comparing recorded dates of applications to the time window of exposure per each subject. The authors declare they have no actual or potential competing financial interests. Of these, 698 were oral ingestions, with 582 exposed via other pathways (dermal, ocular, inhalation, injection, otic exposure, or unspecified). In its 2012 Total Diet Study, the FDA reported neonics were among the most frequently found pesticide residues in infant and toddler foods (occurrence ranging from 6% to 31%) (FDA 2015). That means that neonics are harming the diverse wildlife that pollinates our crops and controls our pests for free. Because of the special selective action on nAChRs in central nervous system of insects, and versatility in application methods, neonicotinoids are used to protect crops and pets from insect attacks globally. This was a possibility with all of the case–control studies. They have a … Neonics have been found to affect mammalian nAChRs in a way that is similar to the effects of nicotine (Kimura-Kuroda et al. 2014); and 35 symptomatic cases (50 controls) (Marfo et al. 2014). (2009). The development of biomarkers for the most heavily used neonics and their metabolites would greatly assist future neonic-human health investigations. The other prospective study, Elfman et al. Questions were rated as “definitely low RoB,” “probably low RoB,” “probably high RoB,” or “definitely high RoB.” Table 2 depicts the questions and RoB ratings for the studies in this review. Thus, the effects of the neonicotinoids on neonatal rat cerebellar cultures imply that there may well be prenatal adverse effects of neonicotinoids in humans. Other studies have found adverse reproductive as well as developmental effects in mammals including reduced sperm production and function, reduced pregnancy rates, higher rates of embryo death, stillbirth, and premature birth, and reduced weight of offspring (Abou-Donia et al. 2015; Simon-Delso et al. The Effects of Neonicotinoids in Bees Many people don’t know about the poisons being put on the plants we are growing. 2015; Tomizawa 2004). Assessment of potential dermal and inhalation exposure of workers to the insecticide imidacloprid using whole-body dosimetry in China. 2013, Gibbons. Although Elfman et al. IMI exposure confirmed in 28 cases, with a median plasma concentration of 10.58 ng/L (IQR: 3.84–15.58 ng/L; range: 0.02–51.25 ng/L) on admission. Autism spectrum disorder, flea and tick medication, and adjustments for exposure misclassification: the CHARGE (CHildhood Autism Risks from Genetics and Environment) case-control study. 2009). (2009) followed clinical outcomes and tracked the toxicokinetics of IMI following acute self-poisonings. The U.S. Department of Agriculture’s (USDA) 2014 pesticide monitoring report found neonics in 12 of 19 different fruits and vegetables sampled, with 11 of these containing multiple neonics, an increase compared to the previous USDA PDP report, which reported neonics were detected in 11 of 17 fruits and vegetables, with only two containing multiple neonics (USDA 2014, 2016). 2014). (2009) reported that concentrations of IMI remained elevated for up to 10–15 hr post-ingestion, suggesting humans have a saturable (zero order) absorption and elimination ability for high doses of IMI. Studies of the in vitro absorption of IMI [44] and ACE [45] using the human intestinal cell line suggest that these neonicotinoids are also absorbed in vivo by active transporters in the intestines. Given the widespread use of neonics in agriculture and household products and its increasing detection in U.S. food and water, more studies on the human health effects of chronic (non-acute) neonic exposure are needed. Exposure assignment differed among the studies as well. Data collection timeframes overlapped among the studies, but differed widely in number of years included. All three developmental studies stated their findings could be the result of chance due to a large number of multiple comparisons (Carmichael et al. (2009). Some people might wonder, if it kills insects, is it really safe for the environment to be using. 2009). As reviewed here, four studies reported low rates of adverse health effects from acute neonic exposure. This period was chosen as it overlaps with the sharp increase in prophylactic use of neonics in U.S. agriculture, particularly neonic-coated seeds and soil injections. 2009), greater understanding of absorption and elimination variability (Marfo et al. Confounding. An overview of the environmental risks posed by neonicotinoid insecticides. Elfman et al. Like nicotine, the neonicotinoids act on certain kinds of receptors in the nerve synapse. (2009) noted exposure was sometimes originally reported in number of mouthfuls, which the researchers quantified by considering one mouthful equal to 25 mL per for an adult or 9 mL per mouthful for a child. Neonictinoid pesticide reduces bumble bee colony growth and queen production. The expansive use of neonicotinoids did not start until 1991, when Bayer CropScience introduced the especially lethal compound, imidacloprid, to the market. The four chronic exposure studies (Carmichael et al. 2014; Keil et al. They are neurotoxic to humans as well. Acute human self-poisoning with Imidacloprid compound: a neonicotinoid insecticide. 2014). Neonicotinoids Affect Hormone Production in Humans May 4, 2018 by Kristina Martin Last updated on: May 4, 2018 Neonicotinoid pesticides are known worldwide for their negative effects on bee populations, but a new study finds that this popular agricultural chemical may also be responsible for elevated levels of a key enzyme in estrogen production. Effects also depend on the health of a person and/or certain environmental factors. 2012) and for memory, cognition, and behavior (Chen et al. Although neonicotinoids are considered low toxicity to mammals and humans in comparison with traditional insecticides, more and more studies show exposure to neonicotinoids pose potential risk to mammals and even humans. Even the most severe outcomes, including two fatalities, may have been mediated by other factors (age, underlying health conditions, undetected coexposures). 2014). (2009) from March 2002 to March 2007. Based on current trends, neonic use is likely to increase due to expanded application of seed treatments for crops in which they are not yet predominant (e.g., soybeans and wheat) and a change in the “standard” seed treatment from the lowest (0.25 mg/seed) to the highest allowable rate (1.25 mg/seed) (Douglas and Tooker 2015). 73 anencephaly cases in San Joaquin valley; 6 exposed/67 not exposed. 2015; Chagnon et al. Quantitative analysis of neonicotinoid insecticide residues in foods: implication for dietary exposures. Catching Up with Popular Pesticides: More Human Health Studies Are Needed on Neonicotinoids. et al. Neonicotinoids effect the nervous systems of insects much more severely than those of mammals, which means that these insecticides are much more toxic to insects. Researchers also reported that neonicotinoids could have similar effects as nicotine on the developing human brain [39,40,41]. Neonicotinoids work as an insecticide by blocking specific neural pathways in insects’ central nervous systems, causing disorientation, inability to feed and death. 2014). 2014). The distribution of age varied significantly among the studies, with children < 19 years comprising 37% of the cases in Forrester (2014) compared to no children < 14 years of age enrolled in Mohamed et al. 2014; Cycoń and Piotrowska-Seget 2015; FDA 2014; Hladik et al. (2014) assigned a time window for pesticide exposure corresponding to 1-month prior to or 2 months post conception. Only one study addressed the toxicokinetics of IMI poisoning. These pesticides may be found in “off-target” food items and persist in the environment. 2009). 2015; Pisa et al. Effects of imidacloprid on human health and the environment depend on how much imidacloprid is present and the length and frequency of exposure. 2009) to 90 mL (range 50–200 mL) (Phua et al. A study using more sensitive analytical techniques than those used by the USDA prior to 2013 also reported finding multiple neonics in several fruits and vegetables (seven apple varieties, oranges, cantaloupe, and spinach) and in five organic honey samples (Chen et al. Human exposure to imidacloprid from dogs treated with Advantage®. 2014; Keil et al. In the developing brain, this subtype is involved in neural proliferation, apoptosis, migration, differentiation, synapse formation, and neural circuit formation (Chen et al. 2015; Gu et al. Studies were not peer-reviewed (e.g., conference abstracts, technical reports, theses and dissertations, working papers from research groups or committees, and white papers). Studies did not assess neonic exposure separately from other pesticide classes. 2008, Gu. 2015; Sánchez-Bayo 2014; Whitehorn et al. Multiple routes of pesticide exposure for honey bees living near agricultural fields. 2014; Jeschke et al. EHP Currently more than 90% of all corn and 44–50% of soybeans are grown from seeds coated with neonics, and they are used extensively on other cereal and oil crops and fruit and vegetables as well (Aginfomatics 2014; Chen et al. Evaluation of the Carcinogenic Potential for, 60109. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V.

(2009) and only two children included among the cases in Phua et al. 2017. Elfman et al. 2015). 407 children with ASD recruited from Childhood Autism Risks from Genetics and Environment (CHARGE) Study/206 controls. Alteration of the density of this neuroreceptor subtype has been found to play a role in several central nervous system disorders, including Alzheimer’s disease, Parkinson’s disease, schizophrenia, and depression. Sci Total Environ 505 :409-422, doi: 10.1016/j.scitotenv.2014.09.090 25461043 . Given the lack of a validated biomarker, however, the urine results did not pertain to IMI. A PICO (population, intervention, comparator, outcome)/PECO (population, exposure, comparator, outcome) statement was developed to address and understand potential effects of neonics on humans (NTP 2015) (Table 1). In the present review, eight studies were identified: four examining the health outcomes of acute neonic exposure and four examining the health effects of chronic (nonacute) neonic exposure. Co‐exposure to neonicotinoids and other classes of pesticides can exert potentiating or synergistic effects, and these mixtures have been detected in human bodily fluids. Total sample sizes included 407 cases of ASD (262 controls) (Keil et al. No deaths reported. In the 1980s Shell and in the 1990s Bayer started work on their development. Cancer Assessment Document. New scientific evidence has led the European Union to progressively restrict the uses of these substances. Elfman et al. These receptors are of critical importance to human brain function, especially during development (Kimura-Kuroda et al. 2014; Keil et al. Our aims here are to review studies on human neonicotinoid exposure levels, health effect, evaluation of potential toxicity and to suggest possible directions for future research. In recent years, neonicotinoids and their metabolites have been successfully detected in various human biological samples. Study design and goals. Three examined the acute health effects of neonic poisonings, including the clinical outcomes of self-poisoning (Forrester 2014; Mohamed et al. 2015; Goulson et al.
