Nyob rau hauv North America,hluav taws kub retardantKev siv khoom sawv ntawm 511,000 tons, nrog rau qhov loj ntawm kev ua lag luam ntawm $ 1.3 billion. Zoo ib yam li Western Europe,txhuas hydroxidecov tshuaj tua hluav taws tseem ceeb, ua raws licov organic phosphorusthiabcov tshuaj brominated nplaim tawsCov tshuaj halogenated flame retardants sawv cev rau 25% ntawm kev ua lag luam, qis dua qhov nruab nrab thoob ntiaj teb, tsav los ntawm kev txwv kev cai rau cov khoom brominated vim muaj kev txhawj xeeb txog ib puag ncig.

Nyob rau hauv kev sib piv, Tuam Tshoj lub lag luam hluav taws xob tseem vam khom rau cov hluav taws xob halogenated, tshwj xeeb tshaj yog cov hom brominated, uas suav txog 40% ntawm kev siv. Muaj peev xwm tseem ceeb rau kev hloov pauv, vim tias kev txo qhov feem no mus rau qhov nruab nrab thoob ntiaj teb ntawm 30% tuaj yeem tso tawm kwv yees li 72,000 tons ntawm qhov chaw ua lag luam txhua xyoo.

Sichuan Taifengtshwj xeeb hauv kev tsim khoomtsis muaj halogen, cov tshuaj tua hluav taws phosphorus-nitrogen uas zoo rau ib puag ncig,siv dav hauvcov tshuaj pleev xim tiv taus hluav taws, roj hmab thiab yas tiv taus hluav taws, cov tshuaj pleev xim rau ntaub, cov nplaum, thiab ntoo tiv taus hluav taws.Cov khoom no ua haujlwm ua lwm txoj hauv kev ruaj khov rau cov tshuaj brominated flame retardants ib txwm muaj, ua raws li cov qauv thoob ntiaj teb rau cov kev daws teeb meem ntsuab dua.
