There is increasing evidence from epidemiological studies that genetic susceptibilities may modify the teratogenic effects of toxic chemicals. However, in contrast to tobacco smoke, few epidemiological studies have addressed environmental chemicals, such as polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans and polychlorinated biphenyls in regard to genetic susceptibility. Recent ...

A cross-sectional study was performed to examine the internal exposure of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDF) in former workers in a nonferrous metal recycling facility. Liver enzymes, lipid parameters, and thyroid hormones were measured to check possible biologic effects. Compared to background levels, the international toxicity equivalent levels of expos...

We compared serum polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) among residents of two homes to levels among age- and sex-matched comparison subjects. The residents of the two homes consumed contaminated eggs and beef from animals raised at the homes. The animals had greater soil contact than those raised with conventional commercial husbandry practices. Th...

Polychlorinated biphenyls (PCBs) are a group of chlorinated aromatic hydrocarbons that have attracted much public health attention. Having been used in industry since the 1930s, PCBs were found to be almost ubiquitous in the environment by 1966.' Owing to their excellent dielectric and insulating properties, PCBs have been used in transformers and capacitors, hydraulic systems, paints and other...

This study employed direct photolysis to treat mixed polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) solutions. The solutions included a synthetic standard 17 2, 3, 7, 8-substituted congeners solution and a practical liquid extracted from the bag filter ash of an electric arc furnace. Additionally, this work utilized a coupled catalyst (ZnO/SnO2) under UV irr...

Polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) are a group of persistent organic pollutants with well‐known toxic effects potential carcinogenicity. Human exposure to PCDD/Fs is mainly through food, including dairy products. The scientific information on the concentrations in milk products here reviewed. It also includes intake consumption these currently decreasing. A similar tr...

In May 2015, a fire occurred at Terminal 3 of the Rome–Fiumicino International Airport. To respond to health concern associated with resulting emissions combustion products, Pier D underwent pre-emptive sequestration. The Italian National Institute Health was asked carry out environmental monitoring affected areas, and evaluate related risk for health. Polychlorinated dibenzo-p-dioxins (PCDDs),...

Abstract Three media (sediment, surface water, and dragonfly larvae tissue) were collected from wetlands surrounding an industrial effluent treatment facility prior to closure. Samples analyzed for metals, total mercury, polychlorinated dibenzo- p -dioxins/polychlorinated dibenzofurans (PCDD/PCDF) concentrations. Sediment water concentrations compared provincial federal guidelines, as well refe...
