영문초록

카드늄에 의해 오염된 토양을 접하는 것은 급격한 산업발달에 의해 아시아에서는 흔한 일이다. 그래서 시민과 관련 당국은 식량작물 소비에 따른 카드늄노출의 위험성에대한 관심을 가지고 있다. 본 개관에서는 전세계 카드늄 소화기관내 흡입과 식품에 근거한 식물에 포함된 카드늄농도에 대한 최근 자료가 모두 제시 되었다. 일반적으로 일용필수품에 근거한 주요 식물에 존재하는 카드늄의 농도는 생체중으로 비교 시 kg 당 0.05mg를 거의 초과하지 않으며 곡류, 두류, 채소, 구근류, 과채류 순으로 감소하였다.

기타언어초록

Agricultural soils contaminated by cadmium (Cd) are common problems in Asia due to rapid industrial development, so the risks of Cd exposure from food crops consumption are concerned by public and authorities. The latest data on Cd concentration in plant-based food and the dietary intakes of Cd around the world are presented in this review. In general, Cd concentrations in major plant-based commodities seldom exceed 0.05 mg/kg fresh weight and decline in the order as: cereals > pulses > vegetables > roots and tubers > fruits in Far Eastern region. In Middle Eastern and European regions, the order is vegetables > cereals > roots and tubers > pulses > fruits. Rice has the highest Cd levels among cereals in Asian countries, but in Middle Eastern and European region the highest level of Cd occurred in leaf vegetables. The dietary intakes of Cd from plant-based commodities around the world declined in the order as: cereals > vegetables > roots and tubers > fruits > pulses. Rice is the largest contributor to total dietary Cd intake (58%) in the Far Eastern region and contributed 36% of Provisional Tolerable Daily Intake (PTDI). For high foodstuffs consumers, intake of Cd from all diets may exceed PTWI, especially for high rice consumers in Asian countries. The World Health Organization (WHO) conducted impact assessment of different maximum levels (MLs) of Cd and demonstrated that each of the four possible MLs for rice had little impact on dietary Cd intake. Since many Cd-contaminated soils in Asian countries still producing crops due to the growing population, the cost-effective techniques for reducing Cd contents in crops especially rice grain are absolutely required.
