Enye yezinkinga ezinkulu zemvelo zesikhathi sethu ukungcoliswa kwamakhemikhali kwemvelo.
Izinhlobo zokungcola kwamakhemikhali
- okuyinhloko - ukungcola kwamakhemikhali kwakhiwa ngenxa yezinqubo zemvelo kanye ne-anthropogenic;
- okwesibili - kwenzeka ngenxa yezinqubo zomzimba nezamakhemikhali.
Abantu sebenakekele ukulondolozwa kwesimo semvelo amashumi ambalwa eminyaka, kufaka phakathi amazwe athuthukile omhlaba enza izinhlelo zombuso zokwenza ngcono isimo semvelo. Ngaphezu kwalokho, isimo sokungcola kwamakhemikhali ezifundeni ezahlukahlukene siyahluka ngamandla.
Abantu bahlangabezana nezinhlanganisela zamakhemikhali empilweni yansuku zonke nalapho besebenza kumabhizinisi ezimboni. Mayelana nalokhu, udinga ukusebenzisa ngokucophelela izimpushana, okokuhlanza nokuhlanza, ama-bleach, izithasiselo zokudla nokunye.
Izinhlobo zokungcola kwamakhemikhali
Ngandlela thile, emzimbeni wezinto eziphilayo ezahlukahlukene, kunezakhi zamakhemikhali ngamanani amancane. Umzimba ulusizo ku-zinc, calcium, iron, magnesium, njll.
Ukungcoliswa kwamakhemikhali kuthelela izingxenye ezahlukahlukene ze-biosphere, ngakho-ke kufanelekile ukugqamisa lezi zinhlobo ezilandelayo zokungcola:
- umkhathi - ukuwohloka kwesimo somoya emadolobheni nasezindaweni zezimboni;
- ukungcoliswa kwezakhiwo, izakhiwo, izindawo zokuhlala nezimboni;
- ukungcoliswa nokuguqulwa kokudla ngezithasiselo zamakhemikhali;
- ukungcoliswa kwe-hydrosphere - amanzi aphansi nangaphezulu, ngenxa yalokho, angena emapayipini amanzi, asetshenziswa njengokuphuza;
- ukungcola kwe-lithosphere - ngesikhathi sokutshalwa kwenhlabathi yi-agrochemistry.
Ukungcoliswa kwamakhemikhali kweplanethi kuthe ngconywana kunezinye izinhlobo zokungcola, kepha kudala umonakalo ongatheni kubantu, ezilwaneni, ezitshalweni nakuzo zonke izinto eziphilayo. Ukulawulwa nokusetshenziswa ngendlela efanele kwamakhemikhali kuzosiza ekwehliseni usongo lwale nkinga yemvelo.
