Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), naphthalenes (PCNs), biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and nonylphenol (NP) were measured in a dated sediment core collected from Tokyo Bay, Japan, in order to study the history of contaminant inputs and fluxes. Concentrations of organochlorine compounds measured in this study increased ...

Heart rate variability (HRV) is a measure of cardiac autonomic regulation that examines the variation in beat-to-beat fluctuations heart rate. While many exposure-based studies have examined effects single or similar groups contaminants on HRV parameters, none association between complex environmental mixtures, including organic and elemental contaminants, HRV. Using data collected from Multi-C...

Fatty acids (FAs) composition, 24 persistent organic pollutants (POPs), and 16 trace elements were examined in small pelagic fish (sardine, anchovy, round sardinella, chub horse mackerels) caught by a fishing fleet for more than three years the eastern Mediterranean Sea. Five Unmix source profiles associated with both sources, such as overlapping diet, including low-niche marine organisms input...

Reports of environmental problems in the former Soviet Union, including excess use of pesticides, have led to concerns about high levels of contamination in humans, but little information is available to assess whether these concerns are warranted. Samples of breast milk from 197 women from two cities in Ukraine were analyzed for p,p'-DDT, p,p'-DDE, endrin, dieldrin, heptachlor epoxide, trans-n...

In view of the large differences between the concentrations of estrogenic chemicals needed to elicit effects in in vitro assays and their levels in human tissues, it is hard to explain possible health risks in terms of exposure to individual compounds. Human populations, however, are exposed to mixtures of estrogenic and estrogen-like agents and it is necessary to consider the impact of combine...
