Evaluation of Pollution of Soils and Particulate Matter Around Metal Recycling Factories in Southwestern Nigeria

Journal of Health and Pollution, 2018
Background. Metal recycling factories (MRFs) have developed rapidly in Nigeria as recycling policies have been increasingly embraced. These MRFs are point sources for introducing potentially toxic elements (PTEs) into environmental media. Objectives. The

Novel Combined Toxicity Indices (CTI) to assess the ecological risk of metals in sediments dependent on fractions and total metal content, application on Qarun Lake sediment, case study

Water Cycle
Fractions and total contents of 21 heavy metals were evaluated in Qarun Lake sediment, a closed and shallow turbid saline lake. The metal contents in the sediments were in the following order: Fe > Al > Ti > Mn > Sr > Zn > Cr > Pb > Ba > Ni > B > Cu > Li
