초록
인산염 농도 변화에 따른 Hizikia fusiforme의 무기비소 축적량 및 생장률을 분석하였다. 무기비소에 14일간 노출하였을 때, 2 mg L-1의 높은 인산염 농도에서 무기비소 축적량이 증가하지 않았다. 하지만 인산염 농도가 0.02 mg L-1로 낮은 경우에 무기비소 축적량이 3배 이상 증가하였다. 또한 H. fusiforme는 인산염 농도가 낮은 경우 생장률이 14.5%, 무기비소 (10 μg L-1)에 노출되었을 경우 생장률이 대조구 대비 30% 감소하였다. H. fusiforme는 인산염과 무기비소를 구분하지 못하여 인산염의 농도가 낮은 경우 무기비소 축적량이 증가하게 되고, 축적된 무기비소는 광합성 저해 및 세포분열을 방해하여 생장률을 억제한다. 특히 우리나라의 대표적인 양식생물인 H. fusiforme는 다른 해조류에 비해 상대적으로 무기비소 축적량이 높다고 알려져있기 때문에, H. fusiforme의 식품안전성을 확보하기 위해 다양한 연구가 필요하다
Abstract
In this study, we performed an analysis of the accumulation of inorganic arsenic and growth rate with changes in phosphate concentration in Hizikia fusiforme. When exposed to inorganic arsenic for fourteen days, we found that the collection of inorganic arsenic hardly increased at high phosphate concentrations (2 mg L-1). However, when the phosphate concentration was low (0.02 mg L-1), accumulation of inorganic arsenic increased. Additionally, H. fusiforme decreased in a growth rate of 14.5% in low phosphate concentration (0.02 mg L-1) and fell in a growth rate of 30% when exposed to inorganic arsenic (10 μg L-1). H. fusiforme cannot distinguish between phosphate and inorganic arsenic. Thus, when phosphate concentration was lower, the inorganic arsenic accumulation increased, and accumulated inorganic arsenic inhibited photosynthesis and cell division, reducing the growth rate. H. fusiforme is known to have higher inorganic arsenic accumulation than other seaweeds. Therefore, various studies are needed to secure the food safety of H. fusiforme which is an essential aquaculture species in Korea.
