丙溴磷对蜈蚣藻的毒性效应 及致毒机理的研究
A Study on the Toxic Effects and Mechanism of Profenofos on Marine Benthic Algae Grateloupia filicina C.Ag.
摘要
Abstract
The biological effects and mechanism of profenofos o n the marine algae—— Grateloupia filicina C.Ag. were studied. The results showed that: (1)In profenofos of low concentrations, the growth wa s stimulated, the chla concentration and the activities of catalase and peroxyda se(POD) were increased. (2)In profenofos of high concentrations，the growth of Grateloupia filicina C.Ag. was inhibited. The 48h EC50 for growth was 3.7 mg/L. the 48h EC50 for photosythesis was 6.19mg/L, and the 48h EC 50 for respiration was 8.47mg/L. Moreover the soluble carbohydrate concen tration was increased, but chla and carotene concentrations were reduced, and the cell electrolytes leaking rate was increased, the CAT and POD activities red ucing.(3)Under the stress of profenofos, the activity of nitrate reductase incre ased dramatically, the maximum was dozens times of the control's. So the activi ty of nitrate reductase is probably a sensible index for the damage level of alg ae under profenofos stress.关键词
