A Study of External Contamination Sources of Traditional Chinese Medicine
中药外源污染物研究现状与分析

We analyzed external contamination sources of traditional Chinese medicine. We consolidated the data of external contamination sources ( pesticides residues, heavy metal, solvent residues, aflatoxin) , and measurement and restriction standards that were published in previous studies, together with our own data. We found that the key to addressing the contamination is to place contamination sources under control using mandatory standards.
