(1)通过现场观测和实验室实验，研究了印度东海岸沿海电厂热排放物对浮游植物的影响。(2)每月进行一次船只巡航（15个月）和实验室实验，研究温度和氯对浮游植物的影响。(3)浮游植物和叶绿素a的下降过程中的水从进口点到出口，而在混合点的叶绿素值恢复显着。(4)实验室实验表明，叶绿素和生产力的下降主要是由于氯化，而不是由于温度升高。(5)温度和氯联合处理对浮游植物的协同作用不大。(6)结果表明，电厂温排水对受纳水体中浮游植物的影响是局部的，对近岸沃茨中浮游植物的分布和丰度没有影响。
(1) The impact of thermal effluents from coastal power plant located on the east coast of India on phytoplankton was studied by field observations and laboratory experiments. (2) Monthly boat cruises (for 15 months) and laboratory experiments were carried out to study the effects of temperature and chlorine on phytoplankton. (3) Phytoplankton and chlorophyll a decreased during the transit of water from intake point to outfall, while at mixing point the chlorophyll values recovered significantly. (4) Laboratory experiments revealed that decrease in chlorophyll and productivity was largely due to chlorination than due to elevated temperature. (5) Combined temperature and chlorine treatment experiments on phytoplankton showed little synergistic effects. (6) It is concluded that the effect of thermal discharge from the power plant on phytoplankton in the receiving water body is quite localized and phytoplankton distribution and abundance in the coastal waters per se are not affected.
