“…Based on these data, 100% of the Ex-R participants were intermittently exposed to several different pyrethroids in their normal diets during the six-week monitoring period. Our study results are similar to Melnyk et al 12 , 28 that also showed low detection frequencies (LOD range = 0.05–0.8 ng/g) for bifenthrin (30%), cyfluthrin (4%), cypermethrin (11%), cis -deltamethrin (1%), esfenvalerate (10%), and cis/trans -permethrin (33%) in 67 solid food samples composited by eating event (breakfast, lunch, dinner, and snack) over several days for nine Hispanic women in Florida USA in 2008. In an earlier study conducted by Riederer et al, 10 the authors reported higher detection frequencies (LOD range = 0.4–0.8 ng/g) than our study for cyfluthrin (59%), cypermethrin (67%), cis -deltamethrin (28%), and cis/trans -permethrin (43%) in duplicate diet samples (composited by food group) of 12 adults collected over eight sampling days in Georgia USA in 2005–2006.…”

“…The most frequently detected pyrethroids (bifenthrin, cis -deltamethrin, cis -permethrin, and trans -permethrin) were found less often in food consumed during period 1 compared to periods 2 and 3. In support of our study results, Melnyk et al 12 , 28 also reported that the mean intake levels of several different pyrethroids were substantially different by type of adult meal sampled (breakfast, lunch, or dinner). In that study, the authors found that the mean intake levels of permethrin, cypermethrin, and esfenvalerate were the lowest in the participants breakfast meals compared to their lunch/dinner meals.…”

Previous research has reported concurrent levels of pyrethroid insecticides and their environmental degradates in foods. These data raise concerns about using these same pyrethroid degradates found in the diet as urinary biomarkers of exposures in humans. The primary objective was to quantify levels of selected pyrethroids and their environmental degradates in duplicate-diet solid food samples of 50 adults over a six-week monitoring period. The study was conducted at the US EPA’s Human Studies Facility in North Carolina and at participants’ residences in 2009–2011. Participants collected duplicate-diet solid food samples on days 1 and 2 during weeks 1, 2, and 6 of the monitoring period. These samples were collected over three consecutive time periods each sampling day. A total of 782 food samples were homogenized and analyzed by LC/MS/MS for seven pyrethroids (bifenthrin, λ-cyhalothrin, cyfluthrin, cypermethrin, cis-deltamethrin, esfenvalerate, and cis/trans-permethrin) and six pyrethroid degradates. Results showed that 49% and 2% of all the samples contained at least one target pyrethroid or pyrethroid degradate, respectively. Cis/trans-permethrin (20%) and bifenthrin (20%) were the most frequently detected pyrethroids. The results suggest that the pyrethroid degradates were likely not present in sufficient levels in the diet to substantially impact the adults’ urinary biomarker concentrations.

“…For the general population, dietary intake may account for a significant proportion of pesticide exposure [42,43,44]. To estimate the dietary exposure to pesticides, national databases of pesticide residues and food consumption are commonly utilized; however, many databases lack the capability to select foods based on cultural and socio-demographic backgrounds [45]. In Mexico, assessing the human exposure to pesticides via dietary intake is complicated because there are no official databases on pesticide residues in agricultural products and the database for daily Mexican dietary consumption data is incomplete [46].…”

Migrant Farmworkers’ Exposure to Pesticides in Sonora, Mexico

Expanding agribusiness in Sonora, a state in Northern Mexico, has increased the demand for temporary migrant agricultural workers. Sonora is one of the top states in Mexico for pesticide utilization. We conducted an exploratory study to evaluate exposure to organophosphate (OP) and pyrethroid pesticides among migrant farmworkers. A sample of 20 migrant farmworkers was recruited from a large commercial grape farm during the harvest season. We administered a questionnaire on work activities, exposure characteristics, and socio-demographics. We collected urine samples to quantify pesticide metabolite concentrations. Most participants were originally from the state of Chiapas, Mexico, none had completed high school, and about half spoke an indigenous language as well as Spanish. The majority of participants had detectable concentrations of pyrethroid and organophosphate biomarkers. Geometric mean creatinine-adjusted concentrations for 3-phenoxybenzoic acid (1.83 µg/g), trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (0.88 µg/g), 4-fluoro-3-phenoxybenzoic acid (0.94 µg/g), 3,5,6-trichloro-2-pyridinol (3.56 µg/g), and para-nitrophenol (0.63 µg/g) were significantly higher than in the general United States’ population and Mexican Americans. Our results also suggest that migrant farmworkers in this region are exposed to pesticides at higher levels than other farmworkers’ studies. Farmworkers’ age, language, training on personal protective equipment, time at the farm, and season, were significant exposure determinants.

“…Among toxic substances which constitute danger to human health attention should also be paid to pesticides, which are a class of biocides commonly used for the protection from pests, including vectors of human or animal diseases as well as unwanted species of plants and animals (Magner and others ). The general population of industrialized countries is exposed to pesticide residues mainly through the diet (Melnyk and others ). Moreover, accidental poisonings caused by these toxic compounds occur among children and farmers (Peiró and others ; Chen and others ).…”

Aronia melanocarpa berries (chokeberries) constitute a very rich source of numerous substances exerting a beneficial impact on health, including mainly polyphenols (proanthocyanidins, anthocyanins, flavonoids, and phenolic acids), possessing antioxidative, anti-inflammatory, antiviral, anticancer, antiatherosclerotic, hypotensive, antiplatelet, and antidiabetic properties. Thus, the consumption of products made from chokeberries is of vital importance for health maintenance and protection. Nowadays, due to the growing prevalence of noncommunicable diseases and ubiquitous human exposure to numerous man-made and naturally occurring toxic substances, some of which are dangerous even at low amounts, it is very important to look for effective means of health protection. An important role in this regard may be played by A. melanocarpa berries; however, up to now the attention of scientists, nutritionists, and health practitioners has been focused mainly on the effectiveness of chokeberry products in the prevention and treatment of noncommunicable diseases, while only little attention has been paid to the possibility of their use to counteract the adverse health effects of exposure to xenobiotics. That is why in this review article the main interest has been focused on the possibility of using chokeberries in the protection against unfavorable health effects caused by the action of substances to which humans may be exposed environmentally and/or occupationally. The available experimental data indicate that not only the fruit but also the leaves of A. melanocarpa and their products may be effective means for prevention and treatment of the effects of toxic action of some xenobiotics in humans; however, further studies on this subject are necessary.
