Zvinopfuura mazana maviri zvidyarwa zvinogadzira makemikari munyika yose - kusanganisira gumi nevaviri muTexas pamwe neGulf Coast - zvichadikanwa kudzikisa huturu hunogona kukonzera gomarara kuvanhu vanogara pedyo pasi pemutemo mutsva weEnvironment Protection Agency wakaziviswa neChipiri.
Zvivakwa izvi zvinoshandisa makemikari ane njodzi kugadzira mapurasitiki, pendi, machira ekugadzira, mishonga yezvipembenene uye zvimwe zvigadzirwa zvepetrochemical.Rondedzero yeEPA inoratidza kuti vangangosvika makumi masere, kana makumi mana muzana avo, vari muTexas, kunyanya mumaguta emahombekombe seBaytown, Channelview, Corpus Christi, Deer Park, La Porte, Pasadena nePort Arthur.
Mutemo mutsva unotarisa pakudzikamisa makemikari matanhatu: ethylene oxide, chloroprene, benzene, 1,3-butadiene, ethylene dichloride uye vinyl chloride.Vese vanozivikanwa kuwedzera njodzi yegomarara uye kukonzera kukuvadzwa kune tsinga, moyo uye immune system mushure mekuratidzwa kwenguva refu.
Sekureva kweEPA, mutemo mutsva uyu ucharova anopfuura zviuru zvitanhatu zvematani emhepo ine muchetura gore rega rega uye kuderedza huwandu hwevanhu vane njodzi yakakwira kenza ne96% munyika yose.
Mutemo mutsva uchadawo kuti zvivakwa zviise fence line yemhepo yekutarisa michina inoyera kudzika kwekemikari chaiyo pamutsetse wenzvimbo yekugadzira.
Isu tinogona kupa akawanda-parameter gasi sensors anogona kutarisa akasiyana magasi
Harold Wimmer, purezidhendi uye CEO weAmerican Lung Association, mukutaura kuti mamonitor ekuona mhepo "achabatsira kuchengetedza nharaunda dziri pedyo nekuvapa ruzivo rwakanyanya nezvemhando yemhepo yavanofema."
Ongororo dzinoratidza kuti nharaunda dzemavara dzine mukana wakakura wekusangana nekusvibiswa kubva kumiti inogadzira makemikari.
Cynthia Palmer, muongorori wepamusoro wepetrochemicals pamwe neasina purofiti Moms Yakachena Air Force, akataura mune yakanyorwa kuti mutemo mutsva uyu "wakadzama kwandiri.Shamwari yangu yepamoyo yakakurira padhuze nemapfumbamwe ezvivakwa zvekugadzira makemikari muTexas izvo zvichafukidzwa mune iyi itsva rulemaking.Akafa nekenza apo vana vake vakanga vari kukireshi.”
Palmer akati mutemo mutsva uyu inhanho yakakosha yekufambira mberi kwekururamisira kwezvakatipoteredza.
Chiziviso cheChipiri chinouya mwedzi mushure mekunge EPA yabvumidza mutemo wekutema ethylene oxide emissions kubva munzvimbo dzekutengesa sterilization.KuLaredo, vagari vanoti miti yakadai ndiyo yakonzera kuti guta riwedzere huwandu hwegomarara.
Hector Rivero, purezidhendi uye CEO weTexas Chemistry Council, akataura mune email kuti mutemo mutsva weEPA uchange uine simba guru pakugadzirwa kwe ethylene oxide, iyo yaakati yakakosha kune zvigadzirwa zvakadai semotokari dzemagetsi uye machipisi emakombiyuta, pamwe chete. sterilizing mishonga yemishonga.
Rivero akati kanzuru, iyo inomiririra nzvimbo dzinopfuura mazana maviri muindasitiri yekugadzira makemikari, ichaenderana nemirairo mitsva, asi anotenda kuti nzira iyo EPA yakaongorora njodzi dzehutano hweethylene oxide yaive nesainzi.
"Kuvimba neEPA pane data rehutsi dzechinyakare kwatungamira kune mutemo wekupedzisira wakavakirwa panjodzi dzakawandisa uye mabhenefiti ekufungidzira," akadaro Rivero.
Mutemo mutsva unotanga kushanda nguva pfupi mushure mekubudiswa muFederal Register.Kudzikisira kukuru kwengozi yegomarara kunobva mukuderedza kuburitswa kwe ethylene oxide uye chloroprene.Zvivako zvinofanirwa kuzadzisa zvinodiwa pakudzikisa ethylene oxide mukati memakore maviri mushure mekunge mutemo watanga kushanda uye zvinofanirwa kusangana nezvinodiwa zve chloroprene mukati memazuva makumi mapfumbamwe kubva zuva rekushanda.
Victoria Cann, mutauriri wesangano rehurumende rinoona nezvezvakatipoteredza, Texas Commission on Environmental Quality, vakataura mukutaura kuti sangano iri richaita ongororo kuti rione kutevedzerwa kwezvinodiwa nemutemo mutsva sechikamu chekutevedzera uye kutevedzera chirongwa.
Mutemo uyu wakanangana nemidziyo panzvimbo yekugadzira makemikari inoburitsa kusvibiswa kwemweya senge masisitimu ekutsinhana kupisa (midziyo inopisa kana zvinwiwa zvinotonhorera), uye maitiro akaita sekufema uye kupisa zvinoburitsa magasi mumhepo.
Kupisa kunowanzoitika panguva yekutanga, kudzima uye kusashanda.MuTexas, makambani akashuma kuburitsa miriyoni mapaundi ekusvibiswa kwakanyanyisa panguva yekutonhora kwaNdira.Vatsigiri vezvakatipoteredza vakadana zviitiko izvozvo maburi mukutevedzwa kwezvakatipoteredza izvo zvinobvumira zvivakwa kusvibisa pasina kurangwa kana faindi mune mamwe mamiriro senge panguva yekunyanyisa kwemamiriro ekunze kana njodzi dzemakemikari.
Mutemo unoda zvivakwa kuita kumwe kuteedzera kushuma uye kuongororwa kwemaitiro mushure mezviitiko zvakadaro.
