As the number of applications containing nanomaterials increase, aquatic ecosystem exposure to nanoparticles (NPs) is unavoidable. In this study, we carried out toxicity assessment to Au-nanoparticles(NPs) of Rana dybowskii eggs and tadpoles. Toxicity was recorded hatching rate, body condition(Snout...

금나노입자가 배아에 대한 독성이 거의 없다는 것을 알 수 있는 연구결과는 어떤 것들이 있는가? | 우리는 금나노입자의 생물영향평가를 위해 농도별 금나노입자에 노출된 북방산 개구리 배아의 부화율과 부화 12시간 후 STL평균을 비교, 분석한 결과 통계적 유의성을 발견하지 못했다. 즉, 실험에서 사용된 농도의 금나노입자는 북방산개구리 배아의 부화율과 부화 12시간 후 유생의 STL에 영향을 주지 않는다고 할 수 있다. Asharani et al., (2011)은 금나노 입자의 크기에 따른 독성 차이를 알아보기 위하여 0, 10, 25, 50, 75, 100㎍/mL 농도의 금나노입자에 D. rerio 수정란을 부화시킨 결과 금나노 농도 증가에 따른 유의한 부화율과 유생의 치사율의 변화를 발견하지 못했다. 또한 토끼를 이용한 in vitro 실험에서도 별다른 독성이 나타나지 않았다(BaKri et al., 2008). | |
나노물질이 포함된 소비제품들은 몇 개나 되는가? | , 2012a). 실제로 우리 주변에 나노물질이 포함된 소비제품들은 1,000여개 이상으로 알려져 있다. 이러한 나노제품들이 증가함에 따라 불가피하게 제조, 사용, 및 처리하는 과정 중에 환경으로 유출될 가능성이 부각되고 있다(Lee and An, 2010; Scholars et al. | |
나노제품들이 증가하면서 생긴 문제는 무엇인가? | 실제로 우리 주변에 나노물질이 포함된 소비제품들은 1,000여개 이상으로 알려져 있다. 이러한 나노제품들이 증가함에 따라 불가피하게 제조, 사용, 및 처리하는 과정 중에 환경으로 유출될 가능성이 부각되고 있다(Lee and An, 2010; Scholars et al., 2011; Zhu et al. |
