Detection of trace levels of persistent pollutants in the environment is difficult but significant. Organic pollutant homologues, due to their similar physical and chemical properties, are even more difficult to distinguish, especially in trace amounts. We report here a simple method to detect polychlorinated biphenyls (PCBs) in soil and distilled spirit samples by the surface-enhanced Raman sc...

during the croatian homeland war in 1991, the capacitor batteries of the zadar electric powersubstation (ts 110/35 kv) were damaged, resulting in the severe pollution of the soil with polychlorinatedbiphenyls (pcbs). due to porosity of karstic soil pcbs represent great environmental and human health risksthat need some action. the polluted soil was collected and an experimental field was formed...

OBJECTIVE Exposure to environmental organochlorines has been examined as a potential risk factor for human breast cancer with mixed results. Our purpose was to examine associations between organochlorines and the development of breast cancer in a large prospective study using stored adipose tissue. METHODS We conducted a nested case-control study of 409 postmenopausal women who developed brea...

Biphenyls and dibenzofurans are the phytoalexins of the Pyrinae, a subtribe of the plant family Rosaceae. The Pyrinae correspond to the long-recognized Maloideae. Economically valuable species of the Pyrinae are apples and pears. Biphenyls and dibenzofurans are formed de novo in response to infection by bacterial and fungal pathogens. The inducible defense compounds were also produced in cell s...

Insects are a promising future source of sustainable proteins within circular economy. Proving the safety insects for food and feed is necessary prior to supplying them market. This literature review provides state-of-the-art overview chemical hazards reared feed, focusing mainly on transfer contaminants from substrate. Contaminants covered are: heavy metals, dioxins polychlorinated biphenyls, ...
