Pine needles are suitable biomonitors of airborne semi-volatile organic compounds (SVOCs). However, the various pine species, each with unique distribution and ecological traits, may differ in their ability to retain pollutants. The SVOC uptake capacities between different vegetation species remain largely unknown, and this study seeks to address this gap.

This study was conducted at Fildes Bay, King George Island, Antarctica, from November 30th, 2019, to January 30th, 2020. We determined the concentrations of Organochlorine Pesticides (OCPs) and Polychlorinated Biphenyls (PCBs) in phytoplankton, and zooplankton. The most abundant compounds found were hexachlorobenzene (HCB) in phytoplankton and γ-HCH in zooplankton.

Introduction: Exposure to environmental chemicals during fetal development may increase the risk of testicular germ cell cancer (TGCC), but few studies have tested the hypothesis. We focused on organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), previously investigated in relation to other male reproductive health outcomes.
Methods: We conducted a nested case-control study of 332 mother-son pairs, comprising 65 TGCC cases and 267 controls, identified from a Danish Pregnancy Screening Registry with biobanked serum samples collected from pregnant women in 1985-1995, when exposure to the studied chemicals was relatively high.
Polychlorinated biphenyls (PCBs) and organochloride pesticides (OCPs) in sediment from the Beibu Gulf, China: Occurrence, spatial-temporal distribution, source, historical variation and ecological risks.

This study comprehensively analyzed 11 polychlorinated biphenyls (PCBs) and 16 organochlorine pesticides (OCPs) in 87 surface sediment samples collected across two seasons and in a sediment core from the Beibu Gulf, China. Overall, only a limited number and low concentrations of PCBs and OCPs were detected. In surface sediments, ΣPCBs concentrations were higher in summer (mean: 0.

Conflicting results across studies thwart consensus on toxicity. In humans, only observational data is available from studies of environmental exposures, complicating the construction of dose-response relationships across the full range of exposure levels.
