He aha te paerewa mō te ihirangi halogen iti mō ngā karapu nitrile halogen iti a Lijiejing?

I tēnei wā, kāore he paerewa ahumahi kotahi mō te ihirangi halogen i roto i ngā karapu nitrile iti-halogen. Ko ngā kamupene me ngā rāngai tono rerekē e kōrero ana mō ngā paepae noa e whai ake nei: <900ppm: I roto i ngā ahumahi hanga me ngā ahumahi hiko whānui, e kiia ana he pai te ihirangi halogen mata i raro i te 900ppm. Ka tutuki tēnei i ngā whakaritenga o te nuinga o ngā taiao mahi tika, ā, ka whakaitihia te tūponotanga o te waikura ki ngā wāhanga hiko. <500ppm: Ko ētahi waitohu, pērā i a Lixin, e hoahoa ana i ngā karapu nitrile iti-halogen 12-inihi mō te hanga wafer 8-inihi me te 12-inihi, e whakahaere ana i te ihirangi halogen i raro i tēnei taumata hei whakaiti ake i ngā tūponotanga poke mō ngā hua tino tairongo. <50ppm: Ko ētahi tauira teitei o ngā karapu Nitrile Iti-Halogen mai i Lixin e pupuri ana i te ihirangi halogen katoa (tae atu ki te fluorine, te chlorine, te bromine, me te iodine) i raro i te 50ppm. Ehara i te mea ka tutuki noa tēnei i ngā ture taiao pakari engari e whakaatu ana hoki i te whakapau kaha ki te tiaki i te taiao whakaputa me te hauora o ngā kaiwhakamahi. Mō ngā tono ahumahi, tukanga rānei, ka tūtohu mātou kia tirohia ngā whakaritenga hangarau ahumahi e tika ana, ngā paerewa kamupene, te whakahaere rānei i ngā whakamātautau ngaio hei whakaū i ngā whakaritenga ihirangi tika. Mā tēnei ka taea te whiriwhiri i ngā hua tiaki e ōrite ana.
