To analyze the basic hygiene status and main health hazard factors of public places in Hainan Province, so as to provide technical support for promoting health management of public places.
The health hazard factors of 200 public places in Hainan Province were monitored in 2022, and the results were statistically analyzed.
A total of 2 339 samples from public places in Hainan Province were monitored, and the overall qualified rate was 83.9%. There were significant differences in the qualified rates of samples from different types of places (χ2=120.63, P < 0.05). Among them, the qualified rates of swimming pools (halls) and hotels (hotels) were relatively low, which were 65.8% and 76.3%, respectively, while the overall qualified rates of the other five types of places were between 85.7% and 96.5%. The main unqualified indexes of indoor air in hotels were formaldehyde, the total number of bacteria, PM10, and PM2.5. The main unqualified indexes of indoor air in barber shops and beauty shops were ammonia and PM10. The main unqualified index of indoor air in shopping malls (supermarkets) was the total number of bacteria. The total number of bacteria detected in all kinds of public goods and appliances in 6 types of public places exceeded the limit. The unqualified rate of pH value of towels in hotels, beauty shops, and barber shops was 43.2%, 13.6% and 11.4%, respectively. The main unqualified indexes of swimming pool were the pH value of swimming pool water, urea and oxidation-reduction potential, and the unqualified rate of oxidation-reduction potential was 29.6%.
The hygienic condition of public places in Hainan Province still needs to be improved in 2022. It is suggested that the relevant departments further strengthen the supervision and monitoring of the total number of bacteria, ammonia, PM10, PM2.5 and formaldehyde in indoor air, the total number of bacteria, coliform group and pH value of towels for public goods, and the redox potential, urea and pH value of swimming pool water.
