The organic acid environmental capacity of mangrove ecosystem in Dongzhai harbor, Hainan, China.

To establish a method for studying the organic acid environmental capacity of mangrove ecosystems, high-performance liquid chromatography was used to measure the organic acid detoxification agent; Using different cultivation methods to determine the toxicity threshold of organic acids on mangrove plants; Calculate the environmental capacity of organic acids by combining the toxicity threshold of organic acids with the volume of water in the study area. The results showed the range of toxicity thresholds of organic acids to 25.29-30 mg/L would have an inhibitory effect on the development of mangrove plant hypocotyls; The organic acid environmental capacity of Dongzhai harbor Mangrove Wetland Protection Area is 7.76 × 10^4 kg/d ~ 8.73 × 10^4 kg/d, while the estimated organic acid emissions from shrimp ponds around Dongzhai harbor are 7.06 × 10^3 kg/d ~ 7.83 × 10^3 kg/d. Therefore, the organic acid emissions from shrimp ponds around Dongzhai harbor are within the carrying range of the mangrove wetland ecosystem in Dongzhai harbor.
