天津市功能区环境空气中恶臭污染现状研究

Odor Pollution in Ambient Air of Tianjin Functional Areas

通过肺式采样法和三点比较式臭袋法,在2010年夏初至2011年春末对天津市的不同功能区的臭气浓度进行了初步监测以及测定。结果表明:天津市夏季恶臭污染在交通区较为严重,超过限值20的样品占44%;秋季恶臭污染在文教区最为严重,超过限值的样品100%;冬季工业区较为严重,占78%;春季居住区和商业区最为严重,超过限值20的样品均占100%。

By using the lungs-manner sampling method and triangle odor bag method,the odor concentration in different functional areas of Tianjin was monitored and tested in early summer of 2010 to late spring of 2011. The results showed that odor pollution was more serious in traffic areas of Tianjin in summer,44% of the samples exceeding the limit 20. In autumn,odor pollution was the most serious in cultural and educational areas,100% of the samples exceeding the limit. Industrial areas were more serious in winter,accounting for 78%. Residential and commercial areas were the most severe in spring,100% of the samples exceeding the limit 20 respectively.
