Effects of acid fog on AC electric performance of polluted insulators;

Besides SO2 and NOx,the atmospheric pollutions also contain acid fog, malodorous gas,H2S,hydrocarbon,HF,HCl,asphalt fume,automobile exhaust,heavy metal,indoor pollution and so on.

The methods of treating the environment of hydrochloric acid production,by recovering the cooling water and the acid water and purifying the acid fog,are introduced.

Study on the adsorbent for the removal of acid mist;

Study on modified fly-ash for the removal of acid mist waste gas;

Metal elements and water-soluble anion concentrations in winter fog water in Nanjing

This paper reported the analysed results of ions species in fog water collected at three sites in Chongqing during December of 2003,also compared with the results obtained ten years ago.

Based on the analysis of sampled fog water in the north suburb of Nanjing city during December 2006,study is conducted of heavy metals of fog water and air pollution in foggy weather.

The paper analyzes disquisition datum of obtained fog water sampling(from 2003yer to 2005yer) and raining water sampling(2005yer) at Nanshan(its altitude 1 922 m,58 km from Urumqi to Nanshan).

Nanshan with an elevation of 1?922 m is located at 58 km from Urumqi,the chemical compositions of the fog sampled in Nanshan by passive fog collector were analyzed,and the contributing factor and influence on the environment were discussed.
