Monitoring of teaching environmental health in primary and secondary schools in 2019 in Beijing / 中国学校卫生

ABSTRACT

Objective@#To understand the sanitation status of teaching environment of schools in Beijing, and to provide basis for school environmental improvement through monitoring it.@*Methods@#In 2019, 661 primary and secondary schools were selected according to the coverage rate of 50% of all schools. Two classrooms were randomly selected from each school for testing, 1 322 classrooms were monitored. The testing contents included per capita area of the classroom, rate of correct desks-chairs adjusting for school height, blackboard size, reflection ratio of blackboard,illumination, carbon dioxide and noise.@*Results@#The qualified rate of noise(92.3%), per capita area(86.5%), blackboard size (85.6%) and illumination uniformity of table top (83.4%) were higher than 80%, while the qualified rate of other indexes were lower than 80%. In 2019, the qualified rate of blackboard size, blackboard average illuminance and blackboard illuminance uniformity were higher than 2018 year(85.6%, 52.7%, 36.2%; 81.9%, 42.7%, 31.7%)(χ2=10.97, 7.80, 5.90, P<0.05), while the noise (92.3%) was lower than 2018 year(98.3%)(χ2=70.82, P<0.05). Both classroom and blackboard, the average illuminance and evenness of the desk and blackboard installed with LED light were higher than those installed with fluorescent lights.@*Conclusion@#Teaching environment monitoring in Beijing is not optimistic. It is necessary to strengthen the promotion and evaluation of standards,and the classroom environment needs to be further improved.
