Concentrations of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were measured in 23 seafood species widely consumed by the Korean population periods 2005–2007, 2010–2011, 2015–2017. The Σ82PCB (sum 82 PCB congeners) Σ19PBDE 19 PBDE concentrations samples 2015–2017 0.06–6.69 ng/g wet weight 0.01–1.60 weight, respectively. significantly correlated. Elevated found fat...

In Western Europe and the United States, protein consumption amounts to about 1.5 to 2 times (Adolf et al. 1994) the recommended intakes (WHO 1985), which is currently considered to be harmless and, according to public opinion, may be even beneficial. Usually relatively short-term experimental studies on the effects of high-protein intakes have been performed, and so the consequences of longer-...

Zearalenone (ZEA) mycotoxin is a potent estrogenic metabolite. It is the primary toxin causing infertility, abortion or other breeding problems. A HPLC method was validated for ZEA in foods using a monolithic column with sample clean-up on an immunoaffinity column. A certified reference material (CRM) from FAPAS (UK) was analyzed. A survey of ZEA was performed on the 72 samples of rice, bread, ...

The prevalence of dental fluorosis in the United States has increased during the last 30 years. In this study, we used a mathematical model commonly employed by the U.S. Environmental Protection Agency to estimate average daily intake of fluoride via all applicable exposure pathways contributing to fluorosis risk for infants and children living in hypothetical fluoridated and nonfluoridated com...

Heavy metal contamination of soils or water can lead to excessive lead (Pb) and cadmium (Cd) levels in rice. As cumulative poisons, consumption of Pb and Cd in contaminated rice may cause many toxic effects in humans. In the present study, Pb and Cd levels in rice samples from Hubei, Jiangxi, Heilongjiang, and Guangdong provinces in China were analyzed by cloud point extraction and graphite fur...

Absorption of heavy metals and contaminants through a rice-based diet may have serious consequences for human health. The present study determined the levels of arsenic (As), cadmium (Cd), lead (Pb) and chromium (Cr) in 71 irrigated and rain-fed rice and assessed dietary (rice) exposure to the heavy metals. The concentration in rice grains were generally higher in the irrigated season which may...

Hazardous substances, such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) also have been detected in Municipal Solid Waste (MSW) and industrial waste incinerators in Korea. In this study, we estimated the exposure status of these hazardous substances and their heath effects in workers and residents near the MSW incinerators and residents near the industri...
