2022年5月14日，加拿大在其官方公報上發(fā)布了擬議的《禁止特定有毒物質(zhì)法規(guī)2022》。75天的公眾咨詢已經(jīng)開始，并將于 2022 年 7 月 28 日結(jié)束。
擬議法規(guī)在最終法規(guī)生效之日起將廢除并取代《禁止特定有毒物質(zhì)法規(guī)2012》（現(xiàn)行法規(guī)）。
擬議法規(guī)新增加了對得克隆DP(Dechlorane Plus)和十溴二苯乙烷DBDPE(Decabromodiphenyl ethane)以及含有這些物質(zhì)的產(chǎn)品的制造、使用、銷售和進(jìn)口實施限制。
擬議議法規(guī)還通過取消某些豁免或限制現(xiàn)行法規(guī)允許活動的方式進(jìn)一步限制全氟辛烷磺酸PFOS、全氟辛酸PFOA、長鏈全氟羧酸LC-PFCAs、六溴環(huán)十二烷HBCD和多溴二苯醚PBDEs以及含有這些物質(zhì)的產(chǎn)品的制造、使用、銷售和進(jìn)口。此外，擬議法規(guī)還包括了這些物質(zhì)的濃度閾值；如果物質(zhì)存在于或低于此閾值時，這些物質(zhì)的存在將被認(rèn)為是偶然存在，禁令將不適用。
