Te Hiranga o ngā PCB Auau-Teitei i roto i te Hanganga Hiko
I te mea kei te haere tonu te uaua o ngā mahi hikohiko, me te tere haere o te tono tere tuku tohus, kua noho ngā PCB auau-teitei hei wāhanga nui i roto i te whanaketanga o tono mahi-teiteingāputa noa i te rāngai whakanao.
Auau-teitei papa hiko tāngaKua noho ngā PCB hei mea nui i roto i te hanga hikohiko, e tuku ana i ngā āhuatanga nui. Ko te tikanga, ka tukuna pai e ngā PCB auau-teitei ngaru hikohikome te iti o te mate, me te whakarite kia rere tohu tere-teiteiKo ngā āhuatanga matua e pā ana ki ngā PCB auau-tiketike ko:
Iti Tauwehenga WhakamararaKo ngā PCB auau-teitei e whakaatu ana i te tauwehenga memeha mai i te 0.0019 ki te 0.025, kia iti ai te ngaronga o te tohu me te pupuri tonu tere tuku tohungā
Iti Pūmau Whakakore HikoHe iti, he pumau hoki te pūmau dielectric o ēnei PCB, e āwhina ana i te maeneene tuku auaume te whakaiti i te whakaroa tohu.
Ātete Matū: He mea tino nui te kaha o ngā PCB auau-teitei ki te tu atu ki ngā matū, e whakarite ana i te ātete ki te waikura me te pai mō ngā taiao e nui ana te pānga ki ngā matū.
He iti te mimiti o te makuku: Nā te iti o te mimiti wai, he pai ngā PCB auau-teitei mō te whakamahi i ngā taiao haukū me te makuku.
Iti Te Pūmautanga o te AhuE mōhiotia ana ngā PCB auau-tiketike mō te pupuri i tō rātou rahi me te kore e pāngia e ngā huringa pāmahana taiao.
I runga i ēnei āhuatanga, he whānui te whakamahinga o ēnei. Heoi anō, me whakarite e ngā kaihoahoa PCB kia tino whaihia ngā mahi e whai ake nei i te wā e hoahoa ana i ngā PCB auau-teitei:
Whakatauhia te PCB auau tohuHe mea nui kia whakatūria ngā whakaritenga ngaohiko me te mana, wehewehea tetahi waka rererangi hikos, me te aromatawai i te taunga o ngā tohu rerekē. Hei tāpiri, he mea nui te whakaiti i ngā taumata manawanui me te whakaiti i ngā taumata haruru.
Te whakarārangi papate whakamahere: Ngā whakaritenga mō te paparanga whakarārangime āta whakamaheretia, me te whai whakaaro ki ngā rauemi motuhake me ōna herenga.
Te whakamahere papa: Me wehewehe te PCB kia rua ngā wāhanga, me te pupuri i te wehenga tika ki ngā wāhi kei roto ngā wāhanga matihiko me ngā wāhanga anaro hei ārai i te pokanoa.
Mana me te papa whenuas: Kia oti te tautuhi i te tahora PCB, he mea nui te mārama ki te mahere whenua. He mea nui te wehewehe i te papa whenua, ā, he mea nui te whakauru i tētahi ātete me te tohu tohu hei whakarei ake i te ara whakahoki.
Whakaitihia te rahi o ngā tauira whenua: He iti ngā papa o ngā PCB auau-teitei. Mā te whakaiti i te wāhi ka āwhina i te whakaiti te kaha o te pirinoaā, ka whakanui ake i te kaha ā-mīhini.
Ara i te tohu auaus: E mōhiotia ana ka puta he irahiko nui mai i ngā tohu auau-tiketike. Mā te ara tika o ngā tohu auau ka ārai i te pokanoa i waenga i ngā tohu.
Whakamahia te ture 3W: Mā te piri ki te ture 3W ka mau tonu te pono o te tohu, ka whakatūria he rerekētanga i waenga i ngā tohu, ā, ka whakaitihia te pānga hononga.
Whakamahia te ture 20H: Ka tūpono pea te hononga i waenga i ngā papa whenua me ngā papa hiko ki tō hoahoa. Mā te ture 20H ka nui ake te matotoru i waenga i ngā papa hiko me ngā papa whenua e tata ana i te papa hiko.
Te Whakamahinga o ngā PCB Auau-Teitei
Kei te piki haere te whakamahinga o ngā PCB auau-teitei, tae atu ki ēnei:
Ngā pūnaha whakawhitiwhiti kōrero i roto i ngā taputapu tātari, whakakahangā teihana whakakahame kaiwhiwhingā
Ngā tono hōia mō te hanga matā me ngā pū.
Pūnaha radare ārahi ana i ngā waka rererangi, e ārai ana hoki i ngā aituā.
Ngā taputapu tātaritanga me te aroturuki tino hira i roto i te umanga hauora.
Hei Whakamutunga
He mea nui ngā PCB auau-tiketike i roto i te hanga PCB hikohiko, ā, he pakari hoki ō rātou āhuatanga e pai ai mō ngā taputapu hiko. He mea nui tā rātou mahi i roto i ngā tono mahi-tiketike, ā, kua rite rātou ki te noho hei mea nui ake i te tipu haere o te uaua o ngā hikohiko me te hiahia mō ngā tere tuku tohu tere ake.
