Analysis on Rural Environmental Health Monitoring Results in Anhui Province, 2011-2015

Objective To understand the situation and dynamic changes of environmental health in rural Anhui Province from 2011 to 2015.

Methods A total of 480 villages in 24 counties were selected by proportional stratified random sampling method and continuously investigated for five years.Monitoring data were collected by data review,interviews,field observation,and so on.

Results The proportion of population with centralized water supply grew from 32.0% to 53.6%,and the prevalence rate of sanitary latrines grew from 17.6% to 27.3%.Landfilling was the main treatment for garbage and the proportions were all more than 75% in each of the five years.Secondary treatment was the main treatment for domestic sewage.However,the proportion of villages carrying out biological vectors control projects were always below 20%,and the proportion showed a downward trend since 2013.

Conclusion The proportion of population with centralized water supply and the coverage of sanitary latrines increase year by year.The main sewage treatment cannot meet modern sewage treatment requirements.A downward trend is found for biological vectors control actions in recent two years,which requires more effective measures to improve rural environmental health.
