Kwemakore anopfuura 75, mercury kusvibiswa kubva kuBadger Army Ammunition Plant kwaisa chepfu hove uye hupenyu hwemumvura muLake Wisconsin, zvichiisa hutano hweveruzhinji panjodzi. Kubviswa kwakachengeteka kwenzvimbo dzakashatiswa kunodikanwa kwazvo kuchengetedza hutano hwevanhu kubva mukuratidzwa kunoenderera.
Iwozvino maseridhi mazinga
Pasinei nedzimwe mbiri dzekare dzakasakara, zvikamu zvinenge 16 maGruber's Grove Bay yeLake Wisconsin zvichiri ine mercury-yakagadziriswa. Mhepo inokonzerwa mune dzimwe nzvimbo munzvimbo iyi iri yakakwirira seye 6.3 milligrams kilogram (mg / kg), kure nechepamusoro pechinangwa chokuchenesa che 0.36 mg / kg yakagadzwa neWisconsin DNR.
Kushandiswa kwehove
Inonyanya kukosha kwehutano hwenharaunda inobatanidza ne mercury mu bay ndiyo kusvibiswa kwehove dzenyama, maererano neWisconsin DNR. Mafuta anowedzera muhove dzehove semethylmercury. Iyi fomu ye mercury ndiyo inonyanya kuisa pangozi yehutano hwevanhu kuburikidza nekushandisa hove dzakasvibiswa.
Kuedzwa neUnited States Army kwakagutsikana kuti mercury mazinga muhove yemhuka yakabatwa muGruber's Grove Bay yakakwirira kudarika inowanika muhove mune imwe nzvimbo yeWisconsin Riverway.
Zvinotambudza vanhu
Vacheche vari mudumbu vanogona kuburitswa kune methylmercury kana amai vavo vachidya hove uye hove ine methylmercury. Uku kuratidzwa kunogona kukanganisa hutano hwevacheche vasati vaberekwa hunowanda uye masisitimu etsinga. Aya masisitimu anogona kunge ari panjodzi yemethylmercury kupfuura uropi uye masisitimu etsinga evakuru ari.
Nhoroondo yeMvura Yakasviba Inobudiswa kuGruber's Grove Bay
Munguva yekushanda kwemakore anoshingaira, Badger Army Zvirimwa Zvirimwa zvakabudisa mvura yakasviba kuGruber's Grove Bay yeLake Wisconsin zvichikonzera kusvibiswa kwemvura yakadzika pasi. Kuisa zvinosvibisa zvinosanganisira mutungamiri, mhangura, arsenic, ammonia, nitroglycerine, PCBs uye methylmercury - iyo inonyanya kuipa ye mercury. Mercury inhengo inonyanyisa uye hapana inonzi inozivikanwa yakachengetedzwa. Zvakanaka, vana kana vakuru havafaniri kuva ne mercury mumitumbi yavo.
