Study on the response of coastal phytoplankton to marine oil pollution
Coastal phytoplankton,as key primary producers within marine ecosystems,significantly influence the ecological balance of the oceans in response to environmental changes,particularly oil pollution.Although extensive research has been conducted on marine oil pollution,detailed mechanisms of phytoplankton's response to oil,especially under varying concentrations of pollution,remain to be thoroughly explored.This study investigates the effects of different concentrations of marine diesel oil on the growth,photosynthetic efficiency,chlorophyll a concentration,lipid content,and antioxidant enzyme activity of phytoplankton through indoor experiments.The results indicate that oil pollution significantly inhibits phytoplankton growth,reduces photosynthetic efficiency and chlorophyll a concentration,affects lipid content,and induces an increase in antioxidant enzyme activity,suggesting that phytoplankton initiate antioxidative defense mechanisms to cope with the stress of oil pollution.Furthermore,the activity of stress response proteins significantly increases with the concentration of oil pollution.The study reveals the dose-dependent effects of oil pollution on phytoplankton within coastal ecosystems,providing crucial insights for understanding the ecological impacts of oil pollution and formulating strategies for marine ecological protection.
