I- ukungcoliswa kwamanzi Kwenzeka lapho izinhlanganisela eziphilayo nezingaphili ezishintsha ukwakheka kwemvelo kwamanzi ziphonswa emifuleni, emachibini nasezilwandle. Lokhu kudala imiphumela eyingozi ezintweni ezihlala kuwo, futhi kubeka engcupheni ukusetshenziswa nokusetshenziswa yizidalwa eziphilayo zalesi sici esibalulekile ukuze zisinde.
Kunezinto eziningi eziyingozi ku-ecosystem yasemanzini, zifinyelela emanzini avela emithonjeni ehlukene, ngokwesibonelo: ukuthuthwa kwezimoto zasolwandle, ukuchitheka kukawoyela, amapayipi ezimboni, ukuchitheka emadolobheni.
Ezimweni eziningi, ukungcoliswa kwamanzi kubangelwa isenzo somuntu. Kodwa-ke, (yize kusezingeni elincane) kunolunye uhlobo lokungcola okwenziwa yindawo uqobo lwayo. Umlotha wentaba-mlilo noma i-mercury yizici zokungcola kwemvelo.
- Kungakusiza: Izimo zemvelo
Ukungcola okukhiqizwa isenzo somuntu
Ukungcola okukhiqizwa ngabantu kuvame ukugxila ogwini nasemanzini angaphezulu. Ngudoti olahlwa ngqo noma ngokungaqondile. Ngokwesibonelo: izibulala-zinambuzane; imfucumfucu engavamile efana no-oyela, uphethiloli, amapulasitiki; amakhemikhali afana nensipho yokuhlanza; udoti wemvelo okhiqizwa izidalwa eziphilayo; izinsimbi ezifana ne-nickel, ithusi, umthofu kanye ne-chromium evela emisebenzini ehlukahlukene yezimboni.
Ukungcola kungenzeka ngendlela yasendaweni, lapho okokusebenza kuvela ngamapayipi endle namapayipi avela ezimbonini, emithonjeni kawoyela nasezimayini; futhi okuvela emithonjeni engamaphoyinti lapho imfucumfucu yamakhemikhali ichithwa ezindaweni ezinkulu zomhlaba.
Ukungcola kwenhlabathi nakho kuveza izinguquko emanzini ngokungcolisa amanzi agcinwe enhlabathini nasemanzini angaphansi komhlaba. Ngaphezu kwalokho, imfucuza ekhona emhlabathini ingathwalwa ngenkasa noma ngamanzi emvula emifuleni nasolwandle.
- Bheka futhi: Ukungcola kwenhlabathi okuyinhloko
Imiphumela yokungcola kwamanzi
- Ukulimala kwemvelo: izinguquko ezitshalweni nasezilwazini zasemanzini.
- Ukungalingani kwemijikelezo yezinto eziphilayo.
- Kubeka imisebenzi yabantu engcupheni efana nokubhukuda, ukuphuza, ukuhlala lapho noma ukukusebenzisela ukukhiqiza ukudla.
- Ukusilela kwamanzi okuphuza okufanele kusetshenziswe izidalwa eziphilayo.
- Izifo nobungozi ezintweni eziphilayo ngenxa yokusebenzisa amanzi esimweni esingesihle.
Izibonelo zokungcola kwamanzi
- Amabhodlela epulasitiki alahlwe ngqo emifuleni noma ezilwandle.
- Imfucuza yamakhemikhali evela ezimbonini.
- Amagciwane, amagciwane nezinambuzane ezingena emanzini kusuka kudoti wemvelo.
- Ukusingathwa kwemisebenzi yezimayini.
- Imikhumbi ichithela uwoyela olwandle.
- Izinto zokugeza nezokuhlanza zazivame ukuwasha izitsha nezingubo.
- Ama-pesticides kanye nezinambuzane.
- Imfucuza yemvelo evela endle.
- Izinto zemisebe.
- Amafutha namafutha.
- Izinsimbi ezisindayo.
- Izinto zokwakha
- Izibonelo eziningi ku: Ukungcola kwamanzi okuyinhloko
