Mining in Shan State, Myanmar, has begun to affect several rivers in Myanmar and Thailand, such as the Len River, Kok River, Ruak River, and Sai River. In particular, the international rivers Kok and Sai River, which flow through Chiang Rai and Chiang Mai provinces, have been found to contain arsenic and other heavy metals before flowing into the Mekong River. This causes people to be concerned about the dangers of toxic substances and the ecosystem, such as aquatic animals, aquatic plants, and agricultural areas that use water that may be at risk of heavy metal accumulation.
