Liver is the major detoxifying centre of the body. It removes xenobiotics and their metabolites through metabolism or biliary excretion. Hepatocytes constitute 80% of total liver mass and play a major role in storage, synthesis, metabolism and redistribution of essential molecules. Liver has been known to accumulate > 90% of nanomatrerials translocated from other organs. Bioconcentration of nanoparticles may lead to impairment of structure and function of hepatic cells. Therefore, it is critical...

Non-sanitary landfill poses enormous threats to lives. In this study, heavy metals in groundwater and soil of residential areas around Awotan landfill, Ibadan, Southwest-Nigeria were quantified and associated environmental and health risks were assessed within 1-150 m and 151-300 m radii. A total of 20 samples of groundwater and soil each were analysed for Pb, Cd, Cr, Ni, Cu, Fe and Zn using Atomic Absorption Spectrometry (AAS). Pb was above the WHO permissible limit in groundwater while Cd was ...

Commonly, reference doses and reference concentrations, toxicity factors supporting non-cancer assessments for the chemical exposures of humans, are rounded values. While the U.S. EPA's Integrated Risk Information System rather evidently employs this rounding practice so as to arrive at toxicity values that are uniform and simple in appearance, the particulars of the rounding approach are only loosely discussed. The analysis provided here found that reference dose and reference concentration rou...
