| the content of dioxins and furans in soils, bottom sediments of water bodies, and tissues of small mammals near the landfill site with municipal solid wastes (moscow, russia). | for the first time, the levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (pcdd/fs) were characterized in the tissues of wild small mammals living in contaminated sites near a municipal solid waste landfill (moscow, russia). the ural field mice sylvaemus uralensis, the bank voles clethrionomys glareolus, and the common shrews sorex araneus were trapped at 1- and 5-km distances from the landfield "salariyevo." high-resolution chromatography-mass spectrometry was used to measure the le ... | 2018 | 30121772 |
