【摘要】：目的了解中山市室内新装修场所的空气污染状况,探讨室内空气污染的风险评估方法。方法选择2007—2011年中山市室内新装修的家居、酒店(旅业场所)、商场、文化娱乐场所和办公场所,分别监测300、813、270、709和969点次,测定指标包括甲醛、苯、甲苯、二甲苯、总挥发性有机物(TVOC)和氡。计算空气质量指数(AQI),结合人体在不同场所的暴露时间,通过风险矩阵(RMA)模型进行风险分析。结果家居、旅业、办公场所、商场、文化娱乐场所的AQI均值分别为0.96、0.80、0.48、0.95和0.61,差异有统计学意义(F=9.474,P0.001);2007—2011年各年度AQI均值呈逐年降低趋势(F=32.774,P0.001)。人群主观感觉与空气质量等级存在正相关(rs=0.734,P0.001)。利用RMA模型得到,家居场所空气污染处于高风险,商场和办公场所处于中等风险,文化娱乐场所和旅业处于低风险。结论基于空气质量和暴露时间,本次调查的新装修场所均存在一定的健康风险。
[Abstract]:Objective to investigate the air pollution status of newly decorated indoor premises in Zhongshan City and to explore the risk assessment method of indoor air pollution. Methods from 2007 to 2011, the newly decorated household, hotel, cultural entertainment and office premises in Zhongshan City were selected and monitored at 300813270709 and 969.The indexes included formaldehyde, benzene, toluene and xylene. Total volatile organic compounds (TVOC) and radon. Air quality index (AQI) was calculated and risk analysis was carried out by risk matrix (RMA) model combined with exposure time of human body in different places. Results the average AQI values of home, hotel, office, shopping mall and cultural and entertainment place were 0.96 / 0.80 / 0. 48 / 0. 95 and 0. 61, respectively. The difference was statistically significant (P < 0. 001). The average value of AQI in each year from 2007 to 2011 was decreasing year by year (P 0. 001). There was a positive correlation between subjective feeling and air quality grade. By using the RMA model, the air pollution in the home is at high risk, the mall and the office are in the middle risk, the cultural entertainment and the traveling industry are in the low risk. Conclusion based on air quality and exposure time, there are some health risks in newly decorated sites.
