广州市民用建筑工程室内环境污染物水平

Civil Building Engineering in Guangzhou: Concentration of Indoor Environment Pollutants

对广州市天河区和白云区182个民用建筑工程进行验收时,共对1730个检测点室内环境的游离甲醛、氨、氡、苯和TVOC等污染物浓度进行检测。结果除室内氡浓度全部检测合格外,其它超过民用建筑工程室内环境污染物浓度限量的检测点有:甲醛(20个)、氨(1个)、苯(31个,其中9个为Ⅱ类民用建筑工程)、TVO(C20个,其中2个为Ⅱ类民用建筑工程)。超过规定限量的检测点全部为已装修的房间,要求对不合格房间采取处理措施后,进行样品数加倍检测,结果全部合格。

Concentrations of contaminants such as free formaldehyde, ammonia, radon, benzene and TVOC at 1730 points of indoor environment in 182 civil building engineering projects were measured in Tianhe and Baiyun District, Guangzhou. Results indicated that except for radon concentration up to the criteria, other pollutants in some points cannot meet the limits, including formaldehyde in 20 points, ammonia in 1 point, benzene in 31 points with which 9 points as civil building engineering of Class II and TVOC in 20 points with which 2 points as civil building engineering of Class II. All unqualified points were the fitment rooms, and the measured results were all qualified after taking measures against the disqualification points.
