BACKGROUND Contamination of vegetable crops (as an important part of people's diet) with heavy metals is a health concern. Therefore, monitoring levels of heavy metals in vegetables can provide useful information for promoting food safety. The present study was carried out in north-west of Iran (Tabriz) on the content of heavy metals in vegetable crops. METHODS Samples of vegetables including...

Background & Aims of the Study: The main objectives of the current research were (1) to study the extent of soil pollution by heavy metals (Ag, Cd, Cr, Cu, Mn, Ni, Pb, Zn, Ba and Li) in sampling locations (2) to investigate the extent of heavy metal pollution and soil to plant transfer of these elements in wheat and barley (3) to study the health risk of heavy metals via consum...

Urbanization can considerably affect water reservoirs by, inter alia, input, and accumulation of contaminants including metals. Located in the course of River Cybina, Maltański Reservoir (Western Poland) is an artificial shallow water body built for recreation and sport purposes which undergoes restoration treatment (drainage) every 4 years. In the present study, we demonstrate an accumulation ...

rodents are sensitive species to and proper monitors of heavy metals in the environment. the accumulation of copper (cu), zinc (zn) and chrome (cr) were measured by wet digestion method and using an icp-oes instrument in hair and liver of persian jird (meriones persicus) in darreh zereshk copper mine, yazd without considering the effects of surrounded mines. results indicated that the concentra...

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

Bioelectrochemical systems (BESs) have been shown to be useful in removing individual metals from solutions, but effective treatment of electroplating and mining wastewaters requires simultaneous removal of several metals in a single system. To develop multiple-reactor BESs for metals removal, biocathodes were first individually acclimated to three different metals using microbial fuel cells wi...

batch adsorption experiments were performed to study adsorption potential of agricultural residues viz. rice straw, wheat straw and salvinia plant biomass for removal of heavy metals such as cr, ni, and cd. plant materials were used in different combinations. heavy metal removal efficiency was more at low metal concentration (35 mg/l). salvinia biomass possessed higher efficiency for removing h...
