广州市河网污染与酸雨相关性研究

Relationship between river pollution and acid rain in Guangzhou

[目的]探讨河网严重污染后对环境的影响,尤其是对酸雨形成的影响。[方法]以广州市河网为例,通过测定河网受严重污染后水体沉积物中H2S、SO2、NH3的排放量,同时对当地的酸雨进行监测。[结果]实验表明,河网污染最严重的晚春、夏、初秋季节,H2S、SO2、NH3的排放量明显增高,且在这段时间,恰好是酸雨频发、严重的时期。[结论]河网污染与局部酸雨的形成有一定的相关性。

[Objective] To investigate the influence of river pollution on environment,especially formation of acid rain. [Methods] The contents of H2S,SO2 and NH3 in the sediments of river in Guangzhou were determined. Meanwhile,the acid rain in Guangzhou was monitored. [Results] The contents of H2S,SO2 and NH3 were significantly increase upon serious pollution of the rivers in late Spring, Summer and early Autumn. During this periods of time,serious acid rain appeared. [Conclusions] River pollution is related to formation of local acid rain.
