Bweendelezi bwakukwabilila busena bwakakankaizya kukasya kubelesya methylene chloride, musamu ngobaamba kuti ulaa ntenda kubuumi alimwi ulakonzya kujaya, kuchitila kutabilila buumi bwabantu boonse.
Muzeezo ooyu ulakonzya kulesya kubelesya musamu wa dichloromethane mubukkale boonse bwabasikuula alimwi amuzintu zinji zyakupanga-panga alimwi azyamakwebo. Dichloromethane ibelesyegwa mukugwisya mafuta, penti akusalazya mabbulashi, zintu zyakunamatika zyamakwebo, antoomwe akupanga makemikalu aambi mumasena aapanga zintu.
Kulesyegwa ooku kwakatalisyigwa mbuli chibeela chamulawu wakukwabilila misamu iikola, ooyo wakapa EPA nguzu zyakuyanda kuti kube malipooti, ​​kubamba zilembedwe, akusunka, azimwi zisinkilizyo. Mu 2019, EPA yakakasya basikuula kubelesya musamu wa dichloromethane kwiinda mukuugwisya kuzwa kuzintu zigwisya penti.
Bantu batasiki ku 85 bakafwa akaambo kakujanika kumusamu ooyu kuzwa mu 1980, kweendelanya a EPA. Environmental Protection Agency yakaamba kuti milandu eeyi bunji bwaziindi yakali kujatikizya babelesi babeleka mulimo wakubambulula maanda. Eeyi mbunga yakaamba kuti kuli "bantu biingi" bakapenga loko mubuumi bwabo kwachiindi chilamfu nikwakamana kujatikizyigwa a methylene chloride. EPA alimwi yakajana kuti kuli ntenda zikonzya kuchitika kubuumi, kubikkilizya akujaya boongo, kuchisa chitaka, antoomwe a kkansa kwiinda mukuyoya akuguma chikumba.
Bbunga lyakabona kuti dichloromethane ilakonzya "kunyonganya buumi bwamuntu mubukkale bwakubelesya" akaambo kantenda kuli babelesi aabo babelesya misamu eeyi, basikuula babelesya misamu eeyi, alimwi abantu babelesya misamu eeyi.
"Sayensi iili musule lya methylene chloride ilisalede, mpawo kujatikizyigwa kulakonzya kuleta mapenzi mapati kubuumi mane akufwa, eezi zili masimpe kumikwasyi myiingi yakafwidwa bayandwa babo akaambo kakunywa misamu iikola," wakaamba mweendelezi wa EPA Michael S. Regan. muswaangano wakaambilizya. "Nchicho chakapa kuti EPA ibweze ntaamu kwiinda mukupa muzeezo wakukwabilila buumi bwababelesi kwiinda mukubikka milawu miyumu yakubeleka iikonzya kulesya kubelesya musamu ooyu akucesya kujanika mubukkale bumbi boonse."
EPA yakaamba kuti makanze aakulesyegwa ooku nkukwabilila bantu kuzwa kuntenda akuzumizya buyo kuti methylene chloride ibelesyegwe mubukkale bweendelezyegwa kapati, calo cikonzya kucesya kujatikizyigwa. Kupanga, kubamba akwaabila dichloromethane kuyoomana mumyezi iilikumi amusanu iiboola. Aawo muzeezo wakakasya musamu ooyu, buvwuntauzi bwa EPA bwakajana kuti zimwi zintu "zijisi muulo weelene akubeleka kabotu ... zilajanwa lyoonse."
"Ooku kulesyegwa kwachiindi chilamfu kutondezya kuyaambele kupati nkotwachita mukubelesya nzila zipya zyakukwabilila misamu akubweza ntaamu zyakachitika chiindi chilamfu zyakukwabilila buumi bwabantu boonse," Reagan wakaamba.
Kerry Breen mweendelezi wamakani asikulemba makani ku CBS News. Makani aakwe abikkila maanu kuzintu zicitika lino, makani mapya alimwi akubelesya misamu iikola.
