Results  From 2015 to 2018, 5 855 samples were collected and 5 528 were qualified. The overall qualified rate was 94.4%. There was a significant difference in the qualified rate, the highest was 98.1% in 2017, and the lowest was 91.5% in 2015. The qualified rate among different years were significantly different (χ²=77.42, P ＜ 0.01). A total of 2 414 samples of indoor air were collected, of which 2 289 were qualified, and the qualified rate was 94.8%. A total of 3 441 samples of public articles were collected, 3 239 samples were qualified, and the qualified rate was 94.1%. Carbon monoxide, coliforms, and Staphylococcus aureus were all qualified, and unqualified samples were determined in the rest four indexes (carbon dioxide, PM₁₀, formaldehyde, and total bacteria count) with qualified rates of 99.5%, 92.3%, 90.1%, and 92.8%, respectively. The qualified rate of PM₁₀ in indoor air of shopping places was higher than that of dewelling places (χ²=23.68, P ＜ 0.01), while the qualified rate of formaldehyde was lower than that of dewelling places (χ²=20.28, P ＜ 0.01). The qualified rates of test indicators of public articles in dewelling places, bathing places, and beauty salons were 98.0%, 97.7%, and 97.8%, respectively, with no significant difference (χ²=0.65, P>0.05). However, the qualified rates of total bacteria count of public articles in these three types of public places were statistically significant (χ²=21.80, P ＜ 0.01), and the qualified rate of beauty salon of 88.1% was the lowest.
