Amanzi ayadingeka empilweni, ngakho-ke kuyamangaza ukuthi aphathwa ngokudelela.
Amanzi ompompi ngokuvamile angcoliswa izibulala-zinambuzane, amakhemikhali ezimboni, imithi, nobunye ubuthi—ngisho nangemva kokwelashwa.
Ukususwa kwamakhemikhali anobuthi njengomthofu, i-mercury ne-arsenic ezikhungweni zokuhlanza amanzi angcolile kuncane futhi akukho kwezinye izindawo. Ngisho namapayipi amanzi ahlanzekile okufanele angene ngawo ezindlini angaba umthombo wobuthi.
Kodwa ngenkathi amagciwane amagciwane ekhishwa emanzini, inqwaba yezinto ezinobuthi, njenge-chlorine, ingena emanzini.
Kungani i-chlorine iyingozi?
I-Chlorine iyingxenye ebalulekile yamanzi kampompi. Asikho esinye isithako samakhemikhali esingaqeda amabhaktheriya namanye ama-microorganisms ngendlela ephumelelayo. Nokho, lokhu akusho ukuthi kufanele uphuze amanzi ane-chlorine noma ukuthi anempilo. I-Chlorine iyingozi kakhulu ezintweni eziphilayo. Ukuqeda i-chlorine emanzini kubalulekile ekugcineni impilo enhle.
Imvelo iwangcolisa kanjani amanzi?
Imithombo yamanzi igcwaliswa ngokungcola okuvela emithonjeni ehlukahlukene. Imfucuza yasezimbonini ngokuvamile ingena emifuleni nasemifuleni, okuhlanganisa i-mercury, i-lead, i-arsenic, imikhiqizo kaphethiloli, nenqwaba yamanye amakhemikhali.
Amafutha ezimoto, i-antifreeze namanye amakhemikhali amaningi ageleza amanzi emifuleni nasemachibini. Izindawo zokulahla imfucumfucu zingomunye umthombo wokungcola, njengoba imfucuza ingena emanzini angaphansi komhlaba. Amapulazi ezinkukhu nawo anomthelela ekuvuzeni kwezinto ezingcolisa umoya, okuhlanganisa nezidakamizwa, ama-antibiotics nama-hormone.
Ngaphezu kwalokho, izibulala-zinambuzane, izibulala-khula kanye namanye amakhemikhali ezolimo agcina esemifuleni ngokuhamba kwesikhathi. Izinto ezilwa nomfutho wegazi ophakeme, ama-antibiotics, ngisho ne-caffeine ne-nicotine azitholakali kuphela emithonjeni yamanzi, kodwa futhi emanzini okuphuza ngokwawo.
Ingabe amanzi asemabhodleleni ayisinqumo esingcono kakhulu?
Akunjalo neze ngaleyo ndlela. Iningi lamanzi asemabhodleleni amanzi kampompi afanayo. Kodwa okubi nakakhulu, amabhodlela epulasitiki ngokuvamile angenisa amakhemikhali emanzini. Amabhodlela avame ukwenziwa nge-PVC (Polyvinyl Chloride), yona ngokwayo eyingozi emvelweni.
Abacwaningi abazimele bahlole okuqukethwe kwamabhodlela amanzi futhi bathola i-fluorine, i-phthalates, i-trihalomethanes ne-arsenic, okungenzeka ukuthi ikhona emanzini ngesikhathi senqubo yokufaka amabhodlela noma ivela emanzini asebhodleleni. Amaqembu emvelo nawo akhathazekile ngenani lezinto ezingcolisayo eziqukethwe emabhodleleni epulasitiki.
Yini esingayenza ukuze siphuze amanzi ngokuzethemba? Thenga isihlungi samanzi esihle futhi usisebenzise! Kulula kakhulu futhi kungcono kusikhwama sakho semali kanye nemvelo kunokuthenga amanzi asemabhodleleni.
