Large areas of soils have been contaminated by heavy metals, which are deleterious to the existence, reproduction and development of living organisms including plants, animals and microorganisms. The contamination of nature compartments by heavy metals has become a serious environmental problem. Due to the high cost of conventional clean-up technologies, there is an increasing interest in the r...

Exploratory geochemistry studies of heavy minerals, stream sediments and rock in Asbkhan region, Heris, northwest Iran

in this article, groundwater samples in urban areas of kerman studied to assess the degree of pollution by heavy metals and major ions and other water quality parameters as a consequence of geology and anthropogenic sources. 43 samples were collected and analyzed by graphite furnace atomic absorption spectrometry, titration and potentiometery for some heavy metals (cd, cr, cu, mn, pb and zn), m...

Sequential leaches (sequential extractions) experiment of 62 elements were carried out for assessing the mobility of contaminated heavy metals and metalloids contaminated in natural sediments; river sediments of Oued El Harrach (Algeria) and lagoon sediments of Bizerte (Tunisia), North African Mediterranean coast. Applied extractants for the sequential leaches are: (A) distilled water for extra...

The organism was found to be metals from the environmental The inorganic minerals like sodium, etc., when present above the permissible limit are harmful. -scale contamination of gravity that is 5 or more times that of water are...

8 A controlled-release formulation (CRF) has been developed for metolachlor, which reduced its 9 leaching in a sandy soil and improved weed control in comparison with the commercial formula10 tion. The current study tested the effect of soil wetting and drying cycles (WDCs) on metolachlor 11 fate (desorption, leaching, and weed control) applied as the CRF and as the commercial formula12 tion. M...
