Natural recovery of contaminated sediments relies on burial of contaminated sediments with increasingly clean sediments over time (i.e., natural capping). Natural capping reduces the risk of resuspension of contaminated surface sediments, and it reduces the potential for contaminant transport into the food chain by limiting bioturbation of contaminated surface or near-surface sediments. This st...

To date, despite the fact it represents a very important part of the national dairy production, no data are available concerning the concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs) in camel milk from the Republic of Kazakhstan. Selected PCDDs, PCDFs, and PCBs were measured in pools of milk from camels (n=15...

Polychlorinated biphenyls (PCBs) are ubiquitous environmental pollutants that have been associated with various adverse health effects in humans and wildlife. Dioxinlike PCBs elicit a broad spectrum of biochemical and toxic changes including cardiovascular disorders. Paraoxonase 1 (PON1), an antioxidant enzyme, prevents oxidative stress and plays key roles in the pathogenesis of atherosclerosis...

BACKGROUND Association between polychlorinated biphenyl (PCB) exposure and breast cancer risk has been widely studied, but the results remain controversial. We performed a meta-analysis to evaluate the evidences from observational studies on PCB exposure and breast cancer risk. METHODS Relevant studies with data on internal PCB dose were identified from PubMed, EMBASE, CBM and CNKI databases ...

The content of polychlorinated biphenyls was determined in human milk collected from four regions of Poland, as well as in cow’s milk and infant formulas. Significant statistical differences in PCB levels were determined in human milk depending on the region. The highest PCB mean concentration (0.351 mg.kg-1 milk fat) was determined in human milk from Gdańsk. An average of 0.218 mg PCB kg-1 mil...

1. The effects of dietary polychlorinated biphenyls (PCB) and excess tyrosine on serum and liver lipids, urinary ascorbic acid and catecholamines were compared in male Wistar rats. 2. Serum levels of cholesterol, urinary ascorbic acid, norepinephrine, epinephrine, dopamine and histamine were significantly increased in rats given either PCB or excess tyrosine. 3. The hypercholesterolaemia induce...

A proposed benefit of wildlife tourism is tourists’ participation in pro-conservation behaviors (PCB). Diffusion theory proposes that one’s perceived efficacy a behavior will influence rates adoption. However, empirical data on factors PCB (PEPCB) are lacking. This study evaluated experiential elements’ PEPCB, and the role social media as an emerging PCB. Data were collected from situ ex touris...

PCB structures like traces couple to the cavity field inside of an enclosure. It has been presented before that the coupling of a trace inside of a homogeneous cavity is caused just by its vertical segments on the trace ends. For an inhomogeneous cavity, consisting of a FR4 PCB layer and an air layer, we show that a trace couples along its whole length. The different coupling must be considered...
