Kev txiav npluav rau Dichhloromethane qhia, txwv tso tawm rau kev siv

Thaum Lub Plaub Hlis 30, 2024, Tebchaws Asmeskas Kev Tiv Thaiv Ib Cheeb Tsam (EPA) muab kev txwv ntawm kev siv cov tshuaj lom neeg ntawm cov tshuaj lom neeg tswj hwm ACT (TSCA).

Rau cov chaw ua haujlwm uas tseem yuav siv Dichhloromshane, feem coob ntawm cov tuam txhab yuav tsum tau ua raws li cov cai tshiab tsis pub dhau 18 lub hlis tom qab kev soj ntsuam cov kev tswj hwm kev pheej hmoo.
