organochlorine compounds such as, polychlorinated biphenyls and organochlorine pesticides are among the best known classes of contaminants because of their potential for magnification and harmful biological effects. in this study, the amounts of organochlorine pesticides including d.d.t and its metabolites, α, β and γ-hchs isomers, σcyclodiene (endosulfan, heptachlor, heotachlor epoxide, aldrin...

Abstract Neighborhood conditions are dynamic; association of changing neighborhood socioeconomic factors with cancer preventive behaviors remains unclear. We examined associations deprivation, gentrification, and change in income inequality adherence to the American Cancer Society (ACS) Guidelines on Nutrition Physical Activity for Prevention The Hispanic Community Health Study/Study Latinos (H...

In Asian developing countries, large amounts of municipal wastes are dumped daily in open dumping sites without proper management. This practice may cause several adverse environmental consequences and increased health risk to local communities. To elucidate contamination by persistent organic pollutants (POPs)--including dichloro-diphenyl-trichloroethane and its metabolites (DDTs), hexachloroc...

UNLABELLED BACKGROUND The serious impact effects of persistent organic pollutants such as organochlorine pesticides, especially dichlorodiphenyltrichloroethane family (DDTs) and hexachlorocyclohexane isomers (HCHs) have been causing widespread concern, despite effective control on their manufacturing, agricultural and vector practices. In that, in addition to the previous global limitations ...

Bovine milk is a nutritious food commodity extensively produced and consumed in Punjab, Pakistan. This study assesses the concentration profile of organochlorine pesticides (OCP; 18 compounds) buffaloes cow’s eight major districts Pakistan potential impacts such exposure. The total OCPs samples ranged from 3.93 to 27.63 ng mL?1 14.64–77.93 respectively. overall pattern mean cows showed that Hex...

liver samples from golden jackal (canis aureus) were collected from noor in the central coastline mazandaran province. the samples of this study were killed in road accidents. levels of persistent organochlorine pollutants (pops) including polychlorinated biphenyls (pcbs), ddts and metabolites, hexachlorocyclohexanes (hchs) and metabolites, hexachlorobenzene (hcb), aldrin and dieldrin were meas...

Self-reported measures of dietary intake are prone to measurement error that may obscure the relationship of diet and disease. This review addresses strategies to decrease errors during collection of dietary data and statistical approaches to deal with measurement issues once the data are collected.  Examples from two US studies-- the Women’s Health Initiative (WHI) Dietary Modificat...

In this study, we evaluate the long-term and seasonal variations of polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), α-, γ-hexachlorocyclohexanes (HCH), p,p′-dichlorodiphenyltrichloroethane (p,p′-DDT) its metabolites through a passive air sampling method at two (urban suburban) stations in Eastern Siberia, Russia, 2011–2017. The median levels HCB, ∑HCHs, ∑DDTs, ∑PCB39, ∑PCB6 were 116,...

Investigators often meta-analyze multiple genome-wide association studies (GWASs) to increase the power to detect associations of single nucleotide polymorphisms (SNPs) with a trait. Meta-analysis is also performed within a single cohort that is stratified by, e.g., sex or ancestry group. Having correlated individuals among the strata may complicate meta-analyses, limit power, and inflate Type ...
