| Abstract: | Under laboratory conditions,the residual chlorine discharged from cooling water of liquefied natural gas(LNG) project was simulated.Toxic effects on Larimichthys crocea larval and juvenile were studied.The results showed that death of larval appeared when the concentrations of residual chlorine were 0.14 and 0.20 mg·L-1,while the mortality of larval was zero in other lower concentration of residual chlorine.The mortality of juvenile fish showed no significantly correlated with residual chlorine.According to the survey in 2009,the average density of larval and juvenile fish were 8.75×106 and 5.39×103 ind.km-2,respectively.Based on diffusion model,the concentrations of residual chlorine in 0.01,0.05 and 0.10 mg·L-1 corresponded with the maximal diffused area 0.248,0.047 and 0.010 km2,respectively.Using interpolation method,the mortality of larval and juvenile fish resulting from three concentrations of residual chlorine was calculated.The values were 0.00%,0.00% and 6.68% for larval,and those were 4.13%,4.72% and 0.92% for juvenile fish.Combined with the evaluation formula W=D ×V × M,the loss of larval and juvenile fish caused by residual chlorine discharged from LNG project were 5.84×105 and 6.77×103 ind,respectively.Survey data in 2010 showed that the average density of larval and juvenile fish were 40.63×106 and 13.89×103 ind.·km-2,which were obviously higher than those in 2009.Obviously,residual chlorine discharged from LNG project had no significant effect on ocean fish in short time. |
