The individual toxicity of lead (Pb) and zinc (Zn) has been investigated by using the sea urchin (Hemicentrotus pulcherrimus) germ cell and pluteus-larvae. The gametotoxic and embryotoxic effects of Pb and Zn on H. pulcherrimus were each investigated at 31, 63, 125, 250, 500 ppb and 16, 31, 63, 125,...

인체로의 납의 노출 경로는 어떻게 되는가? | 2009). 인체에의 납의 노출 경로는 산업체 근로자의 경우 호흡기계로 노출되나 일반적으로는 오염된 물과 토양, 농축산물 및 식품 등을 통한 소화기계가 주된 경로이다 (Park et al. 2006). | |
납의 장기간 노출시 발생하는 문제점은 무엇인가? | 인체의 물질대사에 불필요한 유해금속물질(toxic and non-essential metal)인 납 (lead, Pb)은 화학공업의 각종 장치, 총탄, 축전지의 극판, 페인트의 계면활성제, 자동차 윤활유 및 낚시재료 등에 포함되어 있으며, 미량이지만 장기간 노출 시 체내에 축적되어 다양한 종류의 급, 만성 비 발암성 독성(non-carcinogenic toxicity)을 유발한다(Mahaffey et al. 1981; Mahaffey 1983; Park et al. | |
해양생물 종을 이용하여 해양에 유입되는 독성물질에 대한 생물 반응 연구의 문제점은 무엇인가? | 최근 해양생물 종을 이용하여 해양에 유입되는 독성물질에 대한 생물 반응 연구가 활발이 진행되고 있을 뿐만 아니라 연구의 범위도 점차 넓어지고 있다. 그러나 시험생물 및 독성물질 노출시기 등의 방법의 차이로 인해 독성물질에 대한 생체 내 미치는 영향이 다양하게 나타날 수 있는 문제점이 있다. 이러한 문제점을 해결하기 위해서는 시험방법의 표준화 및 유용 시험생물 종을 선정하는 연구는 매우 중요하다. |
