Metal Contamination in Macrobrachium rosenbergii from Sarawak River, Malaysia and its Health Risk to Human

An assessment of heavy metal concentration in wild-captured Macrobrachium rosenbergii (giant freshwater prawns) from their natural habitat is important since it is susceptible to environmental pollution due to the rapid development and human activities along the Sarawak River. This study aimed to es...
