Food safety tops the list of individual worries among mainland citizens, according to a nationwide survey by a government-backed body. And Beijing, where the Olympics will be held this summer, ranked among the cities where residents felt most dissatisfied with their environment. The findings - published by Xinhua and other state media yesterday - were part of a survey conducted by the China Environment Culture Promotion Association under the leadership of the State Environmental Protection Administration. According to Xinhua, 60.7 per cent of those surveyed ranked food safety as their No1 worry, and about a third expressed concern over the quality of water where they lived. Xinhua did not give details about the survey, such as its size or when it was conducted. When the interviewees were asked to rank a list of public-policy concerns, 66.9 per cent chose the environment, 3.9 percentage points higher than a similar survey in 2006. However, the most selected topic was inflation. Highlighting their concerns, respondents to the survey picked Beijing along with Hefei , Wuhan , Jinan and Lanzhou as the five cities where the environment left a lot to be desired. Zhu Jianping, an environmental-protection official in charge of a planned national pollution survey, said it was the first time more than 10 government ministries had conducted an environmental survey under the leadership of the State Council.
