Since the 2001 U.S. federally mandated phase-out of residential uses organophosphates (OPs), use and potential for human exposure to pyrethroids in indoor environment has increased. We report concentrations common pyrethroids, pyrethroid metabolites, chlorpyrifos floor wipes, urinary metabolites 3,5,6-trichloro-2-pyridinol (TCPy) samples collected 2007-2009 from 90 northern California families as part Study Use Products Exposure Related Behavior (SUPERB). Correlation regression analyses...
The Centers for Disease Control and Prevention (CDC) is involved in many epidemiological studies regarding the measurement of chlorinated pesticides polychlorinated biphenyls specimens obtained from humans. In addition to these commonly determined analytes, there a need include additional persistent organic pollutants (POPs) our analyses, which further stresses analyses because sample volumes remain small. Thus, single method analysis all POPs human serum needed. CDC has recently developed...
Organophosphates and pyrethroids are the most common classes of insecticides used in United States. Widespread use these compounds to control building infestations New York City (NYC) may have caused higher exposure than less-urban settings.The objectives our study were estimate pesticide reference values for NYC identify demographic behavioral characteristics that predict exposures.The Health Nutrition Examination Survey was a population-based, cross-sectional conducted 2004 among adults ≥...
Abstract Background The effects of organochlorine pesticide (OCP) exposure on the development human papillary thyroid cancer (PTC) are not well understood. A nested case-control study was conducted with data from U.S. Department Defense Serum Repository (DoDSR) cohort between 2000 and 2013 to assess associations individual OCPs serum concentrations PTC risk. Methods This included 742 histologically confirmed cases (341 females, 401 males) individually-matched controls pre-diagnostic samples...
DDT (dichlorodiphenyltrichloroethane), a pesticide once used widely in agriculture and now limited to public health use, remains controversial chemical because of combination benefits risks. or its breakdown products are ubiquitous the environment humans. Compounds family have endocrine actions been associated with reproductive toxicity. A previous study reported associations between prenatal exposure p,p -DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)-ethylene] increased height weight adolescent...
Abstract Testicular germ cell carcinoma (TGCC) is the most common malignancy among men ages 20 to 34 years. Although pathogenesis of TGCC poorly understood, suboptimal androgen levels or impaired signaling may play a role. Some persistent organochlorine pesticides commonly found in human tissue possess antiandrogenic properties. We examined whether risk associated with serum 11 pesticides, including p,p′-DDE, and p,p′-DDE-TGCC association modified by CAG GGN repeat polymorphisms receptor...
There are potential adverse health risks to the mother and fetus from exposure pesticides. Thus, studies of pesticides among pregnant women interest as they will assist with understanding burden globally, identifying sources exposure, designing epidemiology studies. We measured urinary concentrations insect repellent N-N-diethyl-meta-toluamide (DEET) two its metabolites [3-diethyl-carbamoyl benzoic acid (DCBA) N,N-diethyl-3-hydroxymethylbenzamide (DHMB)], four pyrethroid insecticide...
A February 3, 2023 train derailment and subsequent burn released hazardous chemicals into East Palestine, Ohio. One potential exposure was polychlorinated dibenzo-p-dioxins, dibenzofurans, coplanar biphenyls (cPCBs), collectively referred to as dioxins. Many studies have linked dioxins numerous health effects. pilot study conducted July 17-18, assess residents' serum dioxin levels. Eighteen persons who were White, nonsmokers with a mean age of 55, 56% female, provided for analysis....
Background . Research suggests that estrogenic endocrine-disrupting chemicals interfere with lactation. Objectives (1) to determine if persistent organic pollutants (POPs) are associated shortened lactation duration; (2) whether previous breastfeeding history biases associations. Methods and Results We measured selected organochlorines polychlorinated biphenyls (<mml:math...
The structural analysis (i.e., identification) of organic chemical entities leached into drug product formulations has traditionally been accomplished with techniques involving the combination chromatography mass spectrometry. These include gas chromatography/mass spectrometry (GC/MS) for volatile and semi-volatile compounds, various forms liquid (LC/MS or HPLC/MS) relatively non-volatile compounds. GC/MS LC/MS are complementary leachables potentially leachable compounds produced via...
Abstract Modern epidemiological studies face opportunities and challenges posed by an ever‐expanding capacity to measure a wide range of environmental exposures, along with sophisticated biomarkers exposure response at the individual level. The challenge deciding what is further complicated for longitudinal studies, where logistical cost constraints preclude collection all possible measurements on participants every follow‐up time. This true National Children's Study (NCS), large‐scale study...
Specific organochlorines (OCs) have been associated with non‐Hodgkin lymphoma (NHL) varying degrees of evidence. These associations not evaluated in Asia, where the high exposure and historical environmental contamination certain OC pesticides (e.g., dichlorodiphenyltrichloroethane [DDT], hexachlorocyclohexane [HCH]) are different from Western populations. We NHL risk prediagnostic blood levels pesticides/metabolites polychlorinated biphenyl congeners a case–control study 167 cases controls...
Web and smartphone surveys are increasingly being used to collect travel information. This workshop explored respondent interaction with these tools, covering a range of research concerns. While facilitate real-time passive collection continuous data, thereby reducing burden, their use raises many issues common those present in web surveys. These include survey design, sample representativeness, privacy, data quality validation. Workshop participants considered possible areas for future on...
