【摘要】：目的了解梅州市梅江区新装修室内空气污染的现状,为室内空气污染防治提供科学依据。方法对梅江区2011—2013年260份新装修后营业前的公共(办公)场所及入住前的家庭居室进行甲醛、苯、甲苯、二甲苯污染情况调查。结果共采集85户260份空气样品,户数超标率为36.47%(31/85),份数超标率25.77%(67/260);检测项目中甲醛超标率最高,为24.62%(65/260),甲醛超标样品中56.92%(37/65)范围集中在0.11~0.21 mg/m3;室内环境中不同类型场所样品超标率差异有统计学意义(χ2=10.9,P0.01),家庭住房超标率最高,为46.15%(18/39);公共场所不同类型场所样品超标率差异有统计学意义(χ2=15.13,P0.01),美容美发店超标率最高,为42.86%(6/14)。结论市民对新装修室内空气污染重视不够,建议装修后至少放置3-6个月再营业或入住;应多通风换气,尤其是在夏、秋季,保证室内空气的质量。

The rate of exceeding the standard was 36.470.The ratio of exceeding the standard was 25.7767 / 260, and the rate of formaldehyde exceeded the standard was the highest.For 24.62% 65 / 260, 56.922% or 37% 65% of formaldehyde exceeded the standard sample. The range was 0.11 ~ 0.21 mg / m ~ (3). There were statistically significant differences in the over-standard rate of samples in different types of indoor environment (蠂 ~ (2 +) 10.9 / P 0.01), and the highest rate of household housing exceeded the standard.There were significant differences in the over-standard rate of samples in different types of places in public places (蠂 ~ 2 ~ 2 ~ (15.13) P ~ (0.01)), and the rate of exceeding the standard in beauty salons was the highest, which was 42.86% ~ (6 / 14).Conclusion the residents pay less attention to the indoor air pollution of the new decoration, and suggest that the indoor air should be kept for at least 3 to 6 months after decoration, and should be ventilated and ventilated, especially in summer and autumn to ensure the quality of indoor air.
