TL;DR: In this paper, the levels of some heavy metals such as; Mn, Cr, Cd, As, Ni, and Pb were analyzed in coal and sediment samples from River Ekulu in Enugu, Coal City using AAS model Spectra-AA-10 variant.

TL;DR: In this paper, the concentrations of iron (Fe), copper (Cu), zinc (Zn), nickel (Ni), manganese (Mn), cadmium (Cd), lead (Pb), and chromium (Cr) in chicken meat, chicken gizzard and turkey meat consumed in southern Nigeria were determined after nitric acid/perchloric acid digestion using graphite furnace atomic absorption spectrophotometry.

TL;DR: The examined metals showed no significant correlation with soil physicochemical properties at the surface horizon, which is suggestive evidence that these metals arise from anthropogenic input.

TL;DR: In this article, the authors investigated polycyclic aromatic hydrocarbons (PAH) compositional patterns and sources and risk of human exposure to PAHs in home dusts through non-dietary ingestion, inhalation and dermal contact pathways.

TL;DR: In this paper, the concentrations of 9 polybrominated diphenyl ethers (PBDEs) and 28 polychlorinated biphenyls (PCBs), including the 7 indicator PCBs and 12 dioxin-like PCBs, were determined in indoor dusts from electronic repair workshops in southern Nigeria.
