Histological Effect of Sodium Hypochlorite (NaOCl), Exposed at Red Tide-killing Concentrations, in Rockfish and Little Neck Clam

적조생물구제농도의 Sodium Hypochlorite(NaOCl)의 노출에 따른 조피볼락 및 바지락의 조직학적 영향

In a previous study by Kim et al. (2000), sodium hypochlorite (NaOCl) has been demonstrated to be effective against algae that cause red tides. To secure the environmental safely of the chemical in practical use, effect of NaOCl, at concentrations required for algicidal activity, on the histology of rockfish and little neck clam was examined. When the animals were exposed to NaOCl at concentrations of 0.5 or 2ppm for 1 hr, there was no exposure-associated histological change in either animal. As the experimental exposure condition was set in consideration of the use, our results provide safety information necessary for practical application to marine fields.
