Efficiency analysis of effluents treatment plants of

Jun 01, 2017Therefore, most common and toxic heavy metals (e.g., Cu, Pb, Cr, Zn and Ni) were evaluated in the study. Results revealed that Cu in inlet effluent varied from 1.27 mg/L to 0.15 mg/L; where the highest (1.27 mg/L) Cu was found at Royal Tec BD but the lowest at Well Group (0.15 mg/L). There were found only 5 industries, e.g. - Mans Fashion

Impact of Soil Heavy Metal Pollution on Food Safety in China

Aug 07, 2015Zn and Cu showed relative lower pollution rates of 3.27% and 2.27%. The Cu, Pb, and Hg pollution rates ranged from 0 to 62.50%, 75.76%, and 76.00%, respectively; while the Zn, Cd, As, and Ni ranged from 0 to 100%. This demonstrated that heavy metal pollutions varied greatly in irrigated areas, mainly due to the quality of the irrigation water.
