Due to their immutable nature, metals are a group of pollutants of much concern. As a result of human activities such as mining and smelting of metalliferous ores, electroplating, gas exhaust, energy and fuel production, fertilizer and pesticide application, etc., metal pollution has become one of the most serious environmental problems today. Phytoremediation, an emerging cost-effective, non-i...

In the context of peri-urban atmospheric pollution by industrial lead recycling emissions, metal can transfer to plant shoots. Home gardeners consuming their produce can therefore be exposed to metal pollution. The Human Health Risk Assessment Protocol (HHRAP) model from the United States Environmental Protection Agency (US EPA) classically used in risk assessment provides foliar metal uptake p...

heavy metal pollution in aquatic ecosystems has become one of the global issues. mollusks such as clams can be used as bioindicators and biomonitors of heavy metal pollution in these ecosystems. in fact, mussels and oysters have been widely used for this purpose. in this study, the concentrations of cadmium were measured in soft tissues of rock oysters )saccostrea cucullata( collected from two ...

this study proposes a method employing thermogravimetric analysis (tg) to predict pollutionlevels by heavy metals (cr, cu, ni, zn, pb, cd and hg) in port sediments close to urban and industrial sitesfrom bay of cádiz. for this purpose, the thermogravimetric results of 14 sediment samples were recorded andshowed two characteristic ranges of temperatures (w1 as weight loss, %: 200-650°c) vs. (w2 ...

The aim of the present study is to evaluate the potential ecological risk and trend of soil heavymetal pollution around a coal gangue dump in Jilin Province (Northeast China). The concentrations of Cd, Pb, Cu, Cr and Zn were monitored by inductively coupled plasma mass spectrometry (ICP-MS). The potential ecological risk index method developed by Hakanson (1980) was employed to assess the poten...
