Heavy Metal Contamination and Its Risk for Swampy Agricultural Soils of Keffi, Nasarawa West, Nigeria

Heavy Metal Contamination in Brazilian Agricultural Soils due to Application of Fertilizers

Potential Health Risk Assessment for Soil Heavy Metal Contamination of Sagamu, South-west Nigeria due to Cement Production

This study was carried out to assess the potential non-carcinogenic health risk of the exposure of children and adults population of Sagamu, southwest Nigeria to heavy metal contamination through soil ingestion pathway. Twenty (20) soil samples were collected randomly between August and October, 2011; wet-digested and analyzed for Pb, Cu, Cr, Cd and Zn by Atomic Absorption Spectrophotometry. Do...

Heavy Metal Contamination and Remediation in Asian Agricultural Land

This paper reviews contamination status, sources and remediation of heavy metals in agricultural land of most Asian countries, with an emphasis to China, which are undergoing rapid economic development. Some farmland soil in suburbs of most cities and sewage irrigation district in China are polluted to some extend with heavy metals such as Cd, As, Zn, Cu, and Hg, consequently resulting in metal...

Assessment of uncertainty and risk in modeling regional heavy-metal accumulation in agricultural soils.

Present agricultural land use and atmospheric deposition may lead to heavy-metal accumulation rates in soils that may violate soil quality standards in the future. To undertake suitable preventive measures against heavy-metal enrichment, flux balances in agroecosystems and their uncertainties have to be assessed. For this reason we developed an empirical stochastic model, PROTERRA-S, that consi...

Human Health Risk Assessment: a Case Study of Heavy Metal Contamination of Garden Soils in Szeged

The soils of the big cities, owing to the various anthropogenic activities, can be contaminated by heavy metals. The surroundings of the roads with heavy traffic as significant metal emitter source can be contaminated by heavy metals. The hobby gardens and the vegetable gardens directly along roads can be potential risky for people since unknown amount of heavy metals can be accumulated into or...
