Inganda zirenga 200 zikora imiti mu gihugu hose - harimo nyinshi zo muri Texas ku nkombe y’inyanja - zizasabwa kugabanya imyuka ihumanya ishobora gutera kanseri ku bantu batuye hafi aho nk'uko byatangajwe ku wa kabiri n'itegeko rishya ry'ikigo gishinzwe kurengera ibidukikije.
Izi nyubako zikoresha imiti ihumanya ikirere mu gukora pulasitiki, amarangi, imyenda ikoze mu nganda, imiti yica udukoko n'ibindi bicuruzwa bya peteroli. Urutonde rwa EPA rugaragaza ko hafi 80, cyangwa 40% byabyo, biherereye muri Texas, cyane cyane mu mijyi yo ku nkombe z'inyanja nka Baytown, Channelview, Corpus Christi, Deer Park, La Porte, Pasadena na Port Arthur.
Iri tegeko rishya ryibanze ku kugabanya imiti itandatu: ethylene oxide, chloroprene, benzene, 1,3-butadiene, ethylene dichloride na vinyl chloride. Byose bizwiho kongera ibyago byo kurwara kanseri no kwangiza uturemangingo tw’imitsi, umutima n’ubudahangarwa bw’umubiri nyuma yo kubikora igihe kirekire.
Nk’uko EPA ibivuga, iri tegeko rishya rizagabanya toni zirenga 6.000 z’imyuka ihumanya buri mwaka kandi rigabanye umubare w’abantu bafite ibyago byinshi byo kurwara kanseri ku kigero cya 96% mu gihugu hose.
Iri tegeko rishya rizasaba kandi ibikoresho byo gushyiraho ibikoresho byo kugenzura uruzitiro rw'umwuka bipima ubunini bw'ikinyabutabire runaka ku murongo w'inganda z'aho uruganda rukorera.
Dushobora gutanga ibikoresho by'umwuka bifite ibipimo byinshi bishobora kugenzura imyuka itandukanye
Harold Wimmer, perezida akaba n'umuyobozi mukuru w'ishyirahamwe ry'abavumvu b'Abanyamerika, yavuze mu itangazo ko ibikoresho bipima ikirere “bizafasha mu kurinda abaturage bo hafi aho bibaha amakuru nyayo ku bijyanye n'ubwiza bw'umwuka bahumeka.”
Ubushakashatsi bwerekana ko imiryango y’abantu bafite ibara ry’uruhu ifite amahirwe menshi yo guhura n’umwanda uturuka ku nganda zikora imiti.
Cynthia Palmer, umusesenguzi mukuru w’ibinyabutabire bya peteroli mu muryango udaharanira inyungu ku bidukikije Moms Clean Air Force, yavuze mu itangazo yanditse ko iri tegeko rishya "rimfitiye akamaro kanini. Inshuti yanjye magara yakuriye hafi y’inyubako icyenda zikora imiti muri Texas zizashyirwa mu bikorwa muri iri tegeko rishya. Yapfuye azize kanseri ubwo abana be bari mu ishuri ry’incuke."
Palmer yavuze ko iri tegeko rishya ari intambwe ikomeye mu butabera bushingiye ku bidukikije.
Itangazo ryo kuwa kabiri ribaye nyuma y'ukwezi kumwe EPA yemeje itegeko ryo kugabanya imyuka ihumanya ikirere ya ethylene oxide ituruka mu nganda zitunganya ibiribwa. I Laredo, abaturage bavuga ko bene izo nganda zagize uruhare mu kwiyongera k'umuvuduko wa kanseri mu mujyi.
Hector Rivero, perezida akaba n'umuyobozi mukuru w'inama y'ubutabire ya Texas, yavuze mu butumwa bw'ibaruwa ko itegeko rishya rya EPA rizagira ingaruka zikomeye ku ikorwa rya okiside ya ethylene, yavuze ko ari ingenzi ku bicuruzwa nk'imodoka zikoresha amashanyarazi na chips za mudasobwa, ndetse no gusya ibikoresho by'ubuvuzi.
Rivero yavuze ko inama njyanama, ihagarariye ibigo birenga 200 mu nganda zikora imiti, izubahiriza amabwiriza mashya, ariko yizera ko uburyo EPA yasuzumye ingaruka z'ubuzima za okiside ya ethylene bwari bufite inenge mu rwego rwa siyansi.
Rivero yagize ati: “Kwishingikiriza kuri EPA ku makuru ajyanye n’ibyuka bihumanya ikirere byashaje byatumye habaho itegeko rya nyuma rishingiye ku ngaruka zikabije n’inyungu zitezwe.”
Iri tegeko rishya ritangira gukurikizwa nyuma gato y’uko risohotse mu gitabo cya Leta Zunze Ubumwe za Amerika. Kugabanya cyane ibyago bya kanseri bizaturuka ku kugabanya imyuka ya ethylene oxide na chloroprene. Ibigo bigomba kuzuza ibisabwa kugira ngo bigabanya ethylene oxide mu myaka ibiri nyuma y’uko iri tegeko ritangiye gukurikizwa kandi bigomba kuzuza ibisabwa kuri chloroprene mu minsi 90 nyuma y’itariki ritangiye gukurikizwa.
Victoria Cann, umuvugizi w’ikigo gishinzwe ibidukikije muri iyo leta, Komisiyo ishinzwe ubuziranenge bw’ibidukikije ya Texas, yavuze mu itangazo ko iki kigo kizakora iperereza kugira ngo gisuzume iyubahirizwa ry’amategeko mashya nk’igice cya gahunda yacyo yo kubahiriza no kubahiriza amategeko.
Iri tegeko rireba ibikoresho byo mu nganda zikora imiti ihumanya ikirere nk'ibikoresho bishyushya cyangwa bikonjesha ibinyobwa, hamwe n'ibikorwa nko gusohora no gutwika imyuka isohora umwuka mu kirere.
Gutwika bikunze kubaho mu gihe cy’ibigo bishya, igihe bigo bifunzwe cyangwa bitagikora neza. Muri Texas, amasosiyete yavuze ko yasohoye ibiro miliyoni imwe by’imyanda ikabije mu gihe cy’ubukonje bwo muri Mutarama. Abashinzwe ibidukikije bavuze ko ibyo bikorwa ari icyuho mu kubahiriza amategeko agenga ibidukikije gituma ibigo bihumanya ibidukikije bitabihaniwe cyangwa bicibwa amande mu bihe bimwe na bimwe nko mu gihe cy’ikirere kibi cyangwa ibiza.
Iri tegeko risaba ko inzego zikora raporo y’inyongera ku bijyanye n’iyubahirizwa ry’amategeko n’isuzuma ry’imikorere nyuma y’ibikorwa nk’ibyo.
