Los contaminantes orgánicos persistentes poseen propiedades tóxicas, son resistentes a la degradación, se bioacumulan y son transportados por el aire, el agua y las especies migratorias a través de las fronteras internacionales; en... more
In this work, we compare the extraction effectiveness of three methods commonly applied for the determination of polychlorinated biphenyls (PCBs) in the spiked soil by transformer oil (Askarel oil). The techniques included are the Soxhlet... more
Reducing the levels of PCB-contaminated dielectric oil is a crucial aspect in the electrical sector. In this regard, both clients and workers of this industry may suffer organic and genetic affectations due to the significant toxicity of... more

As an oil producing Nation with large mineral deposits, coal is one source of energy generation in Nigeria. However, bye-products of these minerals as alternative energy sources include heavy soot, high emissions of greenhouse gases and... more
Aim: The elucidation of temporal trends in human exposure to polychlorinated biphenyls (PCBs) and 17 polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) since the previous Irish human milk surveys and to evaluate the impacts of... more

This study documents changes in contamination over time at seasonal, interannual, and decadal time scales for sport fish collected in San Francisco Bay. Samples from seven fish species were prepared according to common consumption... more
T cell costimulation, particularly by the B7 family members B7-1 and B7-2, plays a critical role in regulating T cell-mediated immunity. Two molecules on T cells, CD28 and CTLA-4, are known to bind to B7. It has been suggested that... more

The aim of this study is to determine potential sources and concentrations of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in surface soils devoted to different land uses in northwest Algeria.... more
A procedure focused on microwave-assisted extraction in open vessel (MAE-OV) and gas chromatography with electron capture detection (GC-ECD) was used for the determination of 26 congeners of polychlorinated biphenyls (PCBs) in soil... more
Environmental change strongly affects primary productivity of ecosystems via modifying bottom-up and top-down regulation of primary producers. Here we present a novel approach to quantify the relative importance of regulating factors in... more
Interactions between gut microbes and anthropogenic pollutants have been under study. The authors investigated the effects of larval exposure to polychlorinated biphenyl 126 (PCB-126) on the gut microbial communities of tadpoles and... more
