Chinese government is ready to carry out its first national survey of pollution sources in February to help control environmental pollution in the country. The study will identify and collect data on sources of industrial, agricultural and residential pollution for two months. Last year, China’ s environment was facing a serious situation, with several major rivers and lakes blocked by industrial waste. China’s environmental cleanup is delayed by more than two decades of rapid economic growth, and a lack of technology especially. Every province has set up an office and will report to a main center staffed by officials from government departments. Data will be reviewed many times before being put into a database and will be analyzed in the second half of 2008. Findings will be examined and approved by mid-2009.
