Neonicotinoids are a class of systemic insecticides widely used on food crops globally. These pesticides may be found in “off-target” items and persist the environment. Despite potential for extensive human exposure, there limited studies regarding prevalence neonicotinoid residues foods sold consumed United States. Residue data seven collected between 1999 2015 by US Department Agriculture’s Pesticide Data Program (PDP) were collated summarized year across various commodities, including...
Recent organic diet intervention studies suggest that is a significant source of pesticide exposure in young children. These have focused on children living suburban communities.We aimed to determine whether consuming an reduced urinary metabolite concentrations 40 Mexican-American children, 3-6 years age, California urban and agricultural communities.In 2006, we collected urine samples over 16 consecutive days from who consumed conventionally grown food for 4 days, 7 then 5 days. We...
Studies report that residential use of pesticides in low-income homes is common because poor housing conditions and pest infestations; however, exposure data on contemporary-use households limited. We conducted a study from urban agricultural communities to: characterize compare house dust levels residential-use pesticides; evaluate the correlation pesticide concentrations samples collected several days apart; examine whether phased-out for uses, but still used agriculture (i.e.,...
Organophosphate esters (OPEs) are synthetic chemicals found in many consumer products, including furniture, electronics, processed foods, and building materials. Emerging vitro vivo studies suggest that OPEs metabolism disrupting compounds; however, epidemiologic investigating their associations with adiposity markers sparse.We examined cross-sectional between OPE biomarkers measures among U.S. children adults participating the National Health Nutrition Examination Survey (NHANES:...
Background: Dialkyl phosphate (DAP) metabolites in spot urine samples are frequently used to characterize children's exposures organophosphorous (OP) pesticides. However, variable exposure and short biological half-lives of OP pesticides could result highly measurements, leading misclassification.Objective: We examined within- between-child variability DAP collected during 1 week.Methods: over 7 consecutive days from 25 children (3–6 years age). On two the days, we 24-hr voids. assessed...
Use of pyrethroid insecticides has increased dramatically over the past decade; however, data on their potential health effects, particularly children, are limited.We examined cross-sectional association between postnatal exposure and parental report learning disability (LD) attention deficit/hyperactivity disorder (ADHD) in children 6-15 years age.Using logistic regression, we estimated associations urinary metabolites with parent-reported LD, ADHD, both LD ADHD 1,659-1,680 participating...
Prenatal exposure to bisphenol A (BPA) may be associated with adverse health effects in the developing fetus; however, little is known about predictors of BPA during pregnancy. We examined 491 pregnant women from Center for Health Assessment Mothers and Children Salinas (CHAMACOS) cohort explored role living United States on significant dietary exposure. Women provided urine samples up two times pregnancy (n=866 total samples). computed intraclass correlation coefficient (ICC) evaluate...
Human biomonitoring (HBM) data measured in specific contexts or populations provide information for comparing population exposures. There are numerous health-based guidance values, but to locate these interested parties need seek them out individually from publications, governmental reports, websites and other sources. Until now, there has been no central, international repository this information. Thus, a tool is needed help researchers, public health professionals, risk assessors,...
Organophosphate esters (OPEs) are an emerging class of chemicals used in a variety consumer products as flame retardants, plasticizers, and additives. While prior epidemiologic studies suggest that OPEs may impact respiratory health, results remain inconclusive. We examined associations between urinary biomarkers symptoms morbidity panel study 147 predominantly Black school-aged children with asthma living Baltimore City, Maryland. The consisted up to four seasonal, week-long, in-home visits...
Although indoor residual spraying (IRS) is an effective tool for malaria control, its use contributes to high insecticide exposure in sprayed communities and raises concerns about possible unintended health effects.The Venda Health Examination of Mothers, Babies their Environment (VHEMBE) a birth cohort study initiated 2012 characterize prenatal IRS insecticides exposures' impacts on child development rural South Africa.In this report, we describe the VHEMBE dichlorodiphenyltrichloroethane...
