Evaluation of heavy metal contamination in paddy plants at the Northern Region of Malaysia using ICPMS and its risk assessment

Heavy metals from natural and anthropogenic sources accumulate in soil and plants and as a consequence represent important environmental contamination problems. Nevertheless, food safety issues and adverse health risks make this one of the most serious environmental issues. The aim of the present st...
