Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and nonand mono-ortho-substituted polychlorinated biphenyls (dioxin-like PCBs) was analyzed in earthworms, plants, insects, field mouse and birds collected in Kanagawa Prefecture and their accumulation in the terrestrial ecosystem was studied. TEQ was highest in raptor species and followed by mouse liver, other bir...

Abstract Atmospheric particulate matter (PM) has a significant impact on both the natural environment and human health. Iron is one of most abundant elements in earth’s crust, playing an important role geochemical processes, also trace component atmospheric PM. In recent years, with rapid development non-traditional (metal) stable isotope technologies, new solutions methods for source apportion...

Lithological and biological features of a fossiliferous tufa in the Kapthurin Formation, Baringo, Kenya, reveal the presence of a lush wetland in a semiarid environment during the Middle Pleistocene (ca 500 ka) in this portion of the East African Rift Valley. Four geological sections, each between 3 m and 8 m in thickness, exposed over a distance of 0Æ5 km, reveal a 1 to 2 m thick paludal tufa ...
