Are brominated flame retardants environmentally friendly?

It must be pointed out that there are more than 70 kinds of brominated flame retardants, and only some of them may have adverse effects on the environment and human beings. However, other brominated flame retardants have no similar effect due to their different structures, so they can be used continuously. It has no scientific basis to put forward the concept of "halogen" is not environmental protection, which is misleading.

From 1995 to 2010, there are few literatures on the production and application technology of decabromodiphenyl ether in China, which indicates that these fields have been fully studied. Since 2004, the number of documents on the environment and regulations of decabromodiphenyl ether has increased significantly, which indicates that people paid more attention to the environmental problems of decabromodiphenyl ether at that time. After 2008, the literature on decabromodiphenyl ether has decreased significantly. The reason for this phenomenon is that following the cancellation of EU exemption in 2008, Oeko tex Standard 100 was listed as a flame retardant in the 2009 revised edition of Oeko tex Standard 100 published by the International Association for research and inspection of eco textiles. The European Union, the United States, Canada and other regions and countries have also announced the date of ceasing the use of decabromodiphenyl ether. Since then, domestic scientific research institutions and manufacturers began to adjust the direction, reduce the research on decabromodiphenyl ether, and turn to the development, development and promotion of its substitutes, so as to find the substitutes with excellent performance as soon as possible.
