Components and acid factors analysis of atmospheric precipitation in Nanhai District of Foshan City

摘要

摘要: 为了解广佛跨界区域佛山市南海区的降水化学组成特征和酸化趋势,于2016年1—12月在南海区采集降水样品,对降水pH、电导率及离子成分进行测定。结果表明:降水pH年均值为5.05,降水的电导率和总离子浓度年均值分别为19.4 μS/cm和6.41 mg/L,南海区2016年的酸雨污染有所改善,但酸雨频率高达63.1%,降水酸化程度仍较高;人为源贡献的N $O 3 -$ 和S $O 4 2 -$ 起主要致酸作用,通过分析S/N发现,N $O 3 -$ 在南海区降水中的致酸作用已超过S $O 4 2 -$ ,成为首要致酸因子。

Abstract: In order to investigate the chemical components characteristics and acidification trend of precipitation at Nanhai District, the cross-border region of Guangzhou and Foshan, the precipitation samples were collected during January to December of 2016. The pH, conductivity and ionic composition of precipitation were analyzed. Results indicated that the annually averaged pH, conductivity and total ion concentration were 5.05, 19.4 μS/cm and 6.41 mg/L, respectively. The acid precipitation pollution of Nanhai District in 2016 had improved, but the frequency of acid precipitation was as high as 63.1%, and the extent of acidification was still relatively high. The N $O 3 -$ and S $O 4 2 -$ which were contributed by the artificial sources played the major roles in the acidification. By analyzing the S/N ratio, it was found that N $O 3 -$ had exceeded S $O 4 2 -$ and become the primary acid factor of precipitation in Nanhai District.
