This study presents for the first time temporal changes of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in Russian human breast milk samples. Concentrations of OCPs and PCBs in samples from three locations in the North West of Russia in 2000-2002 (n=42), were compared to corresponding levels measured in 1993-1996 (n=58). In addition(More)
There is limited information about both environmental and human perfluorinated compounds (PFCs) concentrations in the southern hemisphere, and for the first time, concentrations of these compounds are reported in maternal serum and cord blood of South African women. The majority of the participants were of African Black ethnicity, with a similar(More)
Environmental toxicants such as metals may be detrimental to foetus and infant development and health because of their physiological immaturity, opportunistic and differential exposures, and a longer lifetime over which disease, initiated during pregnancy and in early life, can develop. The placental mechanisms responsible for regulation of absorption and(More)
In support of a feasibility study of reproductive and developmental health among females employed in the Monchegorsk (Russia) nickel refinery, personal exposure and biological monitoring assessments were conducted. The inhalable aerosol fraction was measured and characterised by chemical speciation and particle-size distribution measurements. Unexpected(More)
BACKGROUND Longitudinal biomonitoring studies can provide unique information on how human concentrations change over time, but have so far not been conducted for per- and polyfluoroalkyl substances (PFASs) in a background exposed population. OBJECTIVES The objectives of this study were to determine: i) serum PFAS time trends on an individual level; ii)(More)
The associations between age, body mass index (BMI), parity, place of residence (coastal or inland) and plasma concentrations of perfluorinated compounds (PFCs) were assessed in a study population from south central Vietnam. The study group consisted of 91 delivering women of varied age (18-40 years) from two different locations (37 urban, 36 rural and 18(More)
Polybrominated diphenyl ethers (PBDEs) are one of the most common types of brominated flame retardants applied to foams, plastics and textiles to prevent fires. These flame retardants are now regulated and are either banned or being voluntarily phased. However, as these chemicals are persistent humans continue to be exposed. Dust has been identified as an(More)
Residues of persistent organic pollutants (POPs) were analysed in 70 selected food items from Northwest Russia in 1998-2002. Levels of PCBs ranged from 0.2 to 16ng/g wet weight (ww) in dairy products and fats, 0.2 to 23ng/g ww in meat products, 0.5 to 16ng/g ww in eggs and 0.3 to 30ng/g ww in fish. High levels of DDT (16ng/g ww) were found in locally(More)
BACKGROUND Brominated flame retardants (BFRs) have been in widespread use in a vast array of consumer products since the 1970s. The metabolites of some BFRs show a structural similarity to thyroid hormones and experimental animal studies have confirmed that they may interfere with thyroid hormone homeostasis. A major concern has been whether intrauterine(More)
OBJECTIVES The aims of the study were to compare the prevalence of selected maternal and lifestyle factors as well as the reproductive outcome of working women in two cities in Northwestern Russia (Moncegorsk and Apatity), and to assess the quality of pregnancy-outcome data obtained in an interview with registered information.
