The textbook focuses on the sequential extraction technique as a tool for the impact assessment of dumpsites to its immediate environment.Heavy metals bioaccumulation on the residents' tissues (blood, hair, urine, nails) and other environmental samples (hand-dug well waters, chickens fed with the waste dumps, dust particulate, and gaseous pollutants) were investigated. Some of the health effects associated with these metals exposure include; asthma, typhoid fever, cholera, kidney impairment, cancer, effect of mental development to infants, toxicity to the central and peripheral nervous system...

Total Concentrations of heavy metals (Pb, Cr, Zn, Cd, Mn and Cu) were investigated in soils, Eleusine indica and Lumbricus terrestris from selected solid waste dumpsites of Kano and Kaduna metropolitan cities, Nigeria. The chemical mobility and potential phytoavailability of the metals were also determined in the soils using a six-step sequential extraction procedure. Physicochemical properties of the soils were also assessed using standard procedures. Flame Atomic Absorption Spectrophotometer was used for the chemical analysis of the test sample extracted. The results of the total metal...

This book entitled "Evaluation of Some Heavy Metals Concentrations in Imported Products in Nigeria" is strongly recommended to academics such as environmentalist, biotechnologist, chemists, biochemists, nutritionist. It depicts tools for real-time analysis for chemists and nutritionist in the field work. The results presented herein is recommended to policy maker such as National Food and Drug Administration Commission (NAFDAC).
