In October 2010, nine ministries and commissions of China jointly issued Guidance on the Strengthening of Dioxin Pollution Prevention [Ministry of Environmental Protection of People’s Republic of China (MEP) 2010], which requires key dioxin-emitting industries to carry out comprehensive actions to reduce dioxin emissions. This is a major historical milestone in China’s fight against dioxin pollution. China is one of the largest dioxin-emitting counties in the world, with total annual dioxin emissions from various sources estimated at 10 kg toxic equivalent (TEQ), about half of which is emissions to the atmosphere (Stockholm Convention on Persistent Organic Pollutants 2008). However, efforts to control dioxin pollution in China began later than in developed countries.
