Isesengura ry'imyumvire ku isoko

Igiciro: peteroli muri iki cyumweru, hafi y’uruzinduko rw’Amerika muri Arabiya Sawudite, inama y’imbere muri OPEC, imyaka ibiri ishize inama yo kugabanya umusaruro izarangira, nyuma y’uko haboneka umwanya wo kongera umusaruro mu bihugu byinshi, nka Leta zunze ubumwe z’Abarabu na Arabiya Sawudite.

Ku ruhande rw'ibisabwa: Biteganijwe ko umusaruro rusange w'imbere mu gihugu ABS uzagabanuka gato muri iki cyumweru ugereranije n'icyumweru gishize, kandi icyifuzo cyo hasi gishobora gukomeza kuba intege nke.

Biteganijwe ko isoko rya styrene rizakomera muri iki cyumweru, kandi imikorere yisoko ryigihe kizaza irashobora gukomeza gutandukana.Kuva ku isoko, ibice bishya bizashyirwa mu bikorwa hiyongereyeho kongera gutangira Ikigobe mu ntangiriro za Nyakanga, kandi biteganijwe ko umusaruro w’imbere mu gihugu uziyongera 8.11%.Kugeza ubu, uruzinduko rukurikira rwo kugera ku cyambu nyamukuru ruteganijwe kuba toni 20.500, muri iki cyumweru hashobora kuba toni 15.000 zo kohereza ibicuruzwa hanze kuri terefone, ibyoherezwa mu mahanga, nubwo hari gahunda yo kohereza, ariko hashobora kubaho gutinda, kubara cyangwa kugabanuka gato.Kuruhande rwibisabwa, PS itangira irashobora kwiyongera gake muri iki cyumweru, ABS itangira biteganijwe ko igabanuka, EPS itangira ntabwo ihinduka cyane, imikorere rusange isabwa irahagaze.Kuruhande rwibikoresho, benzene yuzuye namavuta ya peteroli cyangwa kurangiza nabi, inkunga yibiciro irakomeye.Kugeza ubu, inganda zibona isoko zirakomeye by'agateganyo, ahanini zishyigikiwe n’ahantu habi, ariko kandi zihangayikishijwe n’ingaruka z’intege nke za peteroli, ibiciro bya aromatiya byatangiye kugabanuka, bigira ingaruka ku biciro bya styrene.Hamwe n’ibikorwa by’ubuzima rusange by’imbere mu gihugu bikwirakwira hose, kongera imirimo n’umusaruro ku nzira isabwa biteganijwe ko bizatera imbere, styrene mu gihe gito yongeye kwiyongera mu gihe hategerejwe ko ibicuruzwa bizagenda neza, mu gihe giciriritse gikomeza kuba gito.
