Objectives To analyze the status of environmental hygiene in rural areas of Mianyang in 2012, and to provide scientific basis for the management of environment.

Methods Two hundred households from 40 villages in each of 2 counties were selected as subjects by random.

The household owned sanitary latrines accounted for 75.5%. Only 17.5% of wastes were collected by unified management.Most of sewages were discharged to ditches, which were finally excluded into river.Feces were mainly drained into sewer. The contents of lead and cadmium in soil were in the range of 4.99~16.8mg/kg and 0.05~3.27mg/kg respectively. The pH value of water was in the range of 5.50~8.68.The positive rate for ascaris egg in soil was 100% and the rate of live ascaris egg was 95.0%.

Conclusions The coverage of tap water supply was low.Control measures for harmless disposal of garbage, waste water and feces should be strengthened.The soil was plluted by ascaris egg.
