Ukungcola kwamanzi

Esikhathini sethu, ukungcola kwamanzi kuyingozi ngempela. Kunzima kakhulu ukuthola amanzi okumsulwa okwemukelekile ekuphuzeni. Ake sibheke ezinye zezinhlobo eziyingozi kakhulu zokungcola.

Ukungcola kwamakhemikhali amakhemikhali avela kokubili amabhizinisi ezimboni kanye nemfucumfucu yasemakhaya, izigidigidi zamathani ezihlakazeka kuwo wonke umhlaba hhayi nje kuphela, kodwa nolwandle. Izinto zokwenziwa komzimba, isibonelo, ezihlukahlukene zamaplastiki, amapende, ama-polymeric fibers, ahlanzwa emasimini noma ama-pesticides alahliwe, amanye amabhizinisi amakhulu okulima afana nokuxhashazwa, kusho ukusetshenziselwa ukungenisa izakhiwo zamapulangwe nezinye izinto eziningi ezingenakukwazi ukulimala kwemvelo , Kodwa bangabandakanyeka ekusetshenzisweni kwamathambo aphilayo, okwenza lapho njengezinqubo eziphathelene nezinqubo zokugulisa umzimba.

Futhi amakhemikhali athile abangela ukungcola kwamanzi angacutshungulwa yizinto eziphilayo, kodwa ngokuvamile abe yizinto eziyingozi kakhulu eziphilayo eziphilayo kunezokuqala. Ezinye zazo ziyi- carcinogens ezinokwethenjelwa (izinto ezenza ukwakhiwa kwezicubu zomdlavuza), ezinye ziye zaveza izakhiwo ze-teratogenic nezomutageni (okungukuthi, zibangelwa ukungabikho komzimba okungezansi noma ukuguquka kwezinhlobo zezinto eziphilayo). Umphumela onjalo uhambelana nama-hydrocarboni halogenated, ama-polychromatic compounds kanye nama-phenols.

Ukungcoliswa kwamanzi yi-nitrites ne-nitrate kuyingozi kakhulu ezinganeni ezineminyaka yobudala kuze kufike eminyakeni eyishumi nambili. Eziswini zabo, okwamanje asikakhiqiza i-asidi eyanele ukuvimbela lawo mabhaktheriya enza i-nitrate ibe yi-nitrites enobuthi. Kodwa le nkinga ayikhathaleli abantwana kuphela, ama-nitro amakhemikhali anjalo akhiwa ngaphansi kwezimo ezithile ngisho nasesiswini sabantu abadala futhi abangela ubuthi obuvamile. Ngalolu hlobo lwe-poisoning ezisanda kuzalwa, lesi sifo senza i-methhemoglobinaemia, ebizwa ngokuthi "i-blue baby syndrome", ngaleli sifo, i-erythrocyte ilahlekelwa ikhono lokuthwala i-oksijeni, imiphumela yalesi sifo ingaba yingozi.

Izimbangela zokukhula komdlavuza zingaba yi-benzene ne-trichlorethylene ngisho ne-asbestos. Futhi uma ukuhola kungena emzimbeni, i-pathologies engathí sina yengqondo ingase ivele, ikakhulukazi izingane zihlupheka ngalokhu.

Amakhemikhali namakhele e-chlorine ahlanzekile, empeleni asetshenziselwa ukuhlanzwa, kepha abulale ama-microorganisms, ngesikhathi esifanayo agcwalisa amanzi ngamakhemikhali e-organochlorine ayingozi. Kusukela ku-chlorine, amanzi abuye athole ukunambitheka okungathandeki futhi alahlekelwe obala. Futhi lapho kwenzeka ukuthi izidakamizwa ze-organochlorine zingene emzimbeni wesifazane okhulelwe, zingabangela ukukhubazeka okunzima kokuzalwa komntwana, okufana nokulimazeka kwenhliziyo nobuchopho.

Kusuka kumanganese ne-iron, amanzi athola i-black or brownish hue, ukunambitheka kwawo kwehla, ukuthuthukiswa kwamabhaktheriya ensimbi kuqala. Ukusebenzisa isikhathi eside amanzi anjalo kusiza ekuthuthukiseni izifo zegazi, isibindi, ukuvela kwenhliziyo. Ukungcola kwamanzi ngamafutha kuholela ekutheni kutholakale zonke izidakamizwa eziphilayo eziyinkimbinkimbi ezibulala zombili abantu kanye nezitshalo nezilwane zamanzi.

Isikhathi sokuba abantu bacabange ngezenzo zabo, bayeke ukuhlekisa umhlaba, ngoba kunganciphisa kakhulu ukungcola okunjalo njengesintu, ngokunyakaza okungadingekile emkhakheni weplanethi, isibonelo, ukuqhuma komkhumbi omkhulu noma ukuvela kwegciwane elisha. Abantu badinga ukuthanda imvelo, futhi izobuyisela ngokuphindwe kabili.
