Dioxin Bioremediation

The international airport in Da Nang, Vietnam is considered one of the world’s most dioxin-contaminated sites. There are over 187,000 square meters of contaminated soil located in several sites near the airport. The United States government recently initiated a four-year plan to clean up the site at an estimated $43 million dollars. Son Tra Nature Reserve is located approximately 8 km from Da Nang Airport. The nature reserve is comprised of 4,439 total hectares and of those; 4,190 hectares are covered by both primary and secondary forests. According to the World Wildlife Fund (WWF), Son Tra is one of the 200 most important habitats remaining in the world. The nature reserve serves as one of the last remaining intact habitats for the red-shanked douc (Pygathrix nemaeus), an endangered primate native to east-central Lao PDR, central Vietnam, and northeast Cambodia. The red-shanked douc is of great concern to conservationists, as this species has undergone a decline of greater than 50% during the previous three generations (between 30 and 36 years), according to the IUCN Red List. Conservation of these animals, and others, is of increasing importance to the government and people of Vietnam.
