Health Risk Assessment of Heavy Metals and As in Vegetable and Soil System in Chongqing, Southwest of China

Abstract

A systematic survey of heavy metals and As concentrations in vegetables and soil in Chongqing was carried out to assess their potential health risks to local people. The results indicated that the Cr, Cd, Pb and As levels in some vegetables exceeded the Chinese safety standard of pollutants in food. The total carcinogenic risks of the heavy metals and As in 10 kinds of vegetables were all over the standard limits provided by USEPA and ICRP. Therefore, great attention should be paid to the issues of the heavy metals and As pollution in vegetables and the corresponding soil.

Separating and Recycling of Fe, Cu, Zn from Dumped Copper Slag by Microwave Irradiation Assisted Carbothermic Method

“…M ILLIONS of tons of dump copper slag quenched with water in metallurgical plant were dumped each year, which not only employed lots of land resources but also caused serious environmental problems [1][2][3]. Additionally it was proved that copper slag is a source of valuable metals including iron, copper, and zinc.…”

Copper (II) Removed from Aqueous Solutions by Aminated Bagasse Pith

“…These metals, such as Cu, Pb, Cr and Zn, are toxic. Their presence could cause some diseases [1][2][3][4]. For restoration, a lot of effective methods are used to remove polluted ions [5,6].…”
