镇江市细颗粒物中砷的污染状况研究

建立了环境空气颗粒物中细颗粒物中砷的监测方法,结果表明,镇江市空气中细颗粒物中砷金属浓度范围为2.32~37.1 ng/m^3,浓度年均值为7.1 ng/m^3,高于台北、天津和香港,低于北京、广州、南京、武汉。受气候环境的影响,细颗粒物中砷的季节变化趋势存在较大差异,呈现出冬季>秋季>春季>夏季。通过加强政府监管、企业自管、群众强化环保意识,加强对细颗粒物中砷污染的防控。

A monitoring method for determination of arsenic in airborne fine particulate matter is established. The results showed that the concentration range of fine particles in the air in Zhenjing city is of 2.32-37.1 ng/m^3, annual average concentration is 7.1 ng/m^3, higher than Taipei, Tianjin and Hongkong, lower than Beijing, Guangzhou, Nanjing and Wuhan. Due to the ilffluence of climate environment, the seasonal variation trend of arsenic in fine particles is quite different, showing winter 〉 autumn 〉 spring 〉 summer. The arsenic pollution control is strengthened by strengthening government supervision, self-management of enterprises and strengthening people＇s environmental protection awareness.
