A survey into soil pollution in China is a "state secret," according to the country's environmental authorities, which have refused a Beijing lawyer's request for it to be published.

The lawyer, Dong Zhengwei, told the Legal Daily newspaper that he e-mailed the Ministry of Environmental Protection on January 30 asking it to publish information about its survey, including testing methods, results, causes of soil pollution and its prevention.
The survey dated from as early as 2006 but its conclusions have never been made public, the newspaper said.
Dong said he received a reply from the ministry on Sunday, a 22-page letter that didn't include any information about the survey's results.
The ministry wrote that it refused to publish the survey results because the information was a state secret.
Dong told the newspaper: "The ministry has claimed to Chinese media several times that it would publish data covering its survey of China's soil pollution after it is permitted to do so by the State Council.
"Now it seems like the soil pollution in China is so serious that the environment authorities dare not publish the result."
Dong said the ministry's refusal may have violated the rules governing the publication of government information.
Ma Jun, director of the Institute of Public and Environmental Affairs, told the newspaper that soil pollution in China was directly linked to residents' health and the ministry could not deprive residents' right to know by simply labeling the information as a state secret.
