Abstract

This paper is the monitoring results of some heavy metals (lead, cadmium, arsenic, mercury) in herbal medicines and their intake rates. The monitoring of lead, cadmium, arsenic and mercury was carried out on 600 samples with 60 kinds of herbal medicines. And the transfer ratio of heavy metals in the water-boiled drinks w as calculated. The results show that lead was detected over the Maximum Residue Limits (MRL) in 10 samples (7 species). Cadmium was detected over the MRM in 69 samples (19 species). Arsenic was detected over the MRM in 3 samples (3 species). Mercury was detected over the MRM in 13 samples (10 species). We need continuously monitoring to ensure confidence and safety for these herbal medicines. In case of the water-boiled drink, average intake rates of lead, cadmium, arsenic and mercury are 9.77%, 6.72%, 26.1% and 6.79%, respectively.

국내에 유통되고 있는 국산, 수입 한약재 60품목에 대하여 품목당 10개씩 총 600개를 선정하여 중금속 중 납, 카드뮴, 비소 와 수은 4가지의 오염현황을 파악하고, 한약재를 우리가 직접 섭취하는 제제 형태인 탕제로 만들어 중금속의 이행률을 산정하였다. 모니터링 결과 허용한계치를 초과한 납은 10개, 7품목, 카드뮴은 69개, 19품목, 비소는 3개, 3품목, 수은은 13개, 10품목으로 이들의 지속적인 모니터링이 필요할 것으로 판단되며, 93개의 한약재 중 72개의 원산지가 중국산임을 감안할 때, 한약재를 수입하고 유통하는 과정에서의 품질평가와 안전관리를 위한 지속적인 연구가 필요할 것으로 사료된다. 고농도 10 품목에 대한 탕제의 가용 섭취율 실험 결과, 이행률 평균값은 납의 경우 9.77%, 카드뮴은 6.72% 비소는 26.1%와 수은은 6.79%를 나타내었다.
