Lasut. Sub-Laboratory of Toxicology & Marine Pharrnaceutics, Laboratory of Marine Sciences. Faculty of Fisheries & Marine Sciences, Sarn Ratulangi Uniuersity, JI. Kampus Unsrat Bahu, Manado 95 11 5, Indonesia ABSTRACT Effects of salinity (25-35 %o) interaction with cyanide (KCN and NaCN) on survival have been tested on abalone Haliotis uaria. Highest mortality occurred at a salinity of 25 %o and 4 ppm of both forms of cyanide. The lowest salinity could have caused stress, making abalone more sensitive. The effect of cyanide on survival was significant at 1 ppm of KCN and 2 ppm of NaCN Q?<0.05), while the salinity and the interaction with cyanide were not (p>0.05). Seemingly, the KCN was more toxic than the NaCN. INTRODUCTION Cyanide (CN-) occurs in marine environ- The objective of the present study is to ments in combination with ions of saline investigate the effects of salinity-cyanide water, forming potassium sait cyanide acid (KCN & NaCN) interaction on the mortality (KCN) and sodium salt cyanide acid (NaCN) of the intertidal abalone Haliotis uaria. compounds. Cyanide also exists as HCN, a Abalones have rarely been used as test very toxic compound. It is naturally found organisms for toxicity tests, although they in the marine waters in very low have been used to study the interactive concentrations. However, its concentration effects of pentachlorophenol and hypoxia may increase due to pollution by cyanide- (Tjeerdema et al. t99la), the sublethal containing waste. effects of pentachlorophenol (Tjeerdema ef Cyanide is widely used in industries to al.799lb), the effects ofgas supersaturation extract metals, such as gold from ores, in on the behaviour, growth and mortality metal refining, metal cleaning and (Leitman 1992), the interactive effects of electroplating operations, and in certain pentachlorophenol and temperature mineral processing operations.
