Leading IT firms 'silent' on pollution

Expert calls for stricter enforcement of law on heavy metal discharge standards

Beijing - Strict law enforcement is needed to prevent heavy metal pollution, which already poses a threat to the country's soil and water, a leading environmental researcher said.

According to China's policy on the disclosure of environmental information, which was implemented in May 2008, companies that exceed their emission limits are required to publish details of their pollution discharge in local media within 30 days of their being blacklisted.
