I-Sea of Japan itholakala emaphethelweni oLwandlekazi iPacific. Njengoba ichibi linezinkinga ezifanayo zemvelo njengezinye izilwandle zomhlaba, ohulumeni bala mazwe bathatha izinyathelo ezahlukahlukene ukulondoloza ubunjalo bolwandle. Umthelela ohlelweni lwe-hydraulic lwabantu ezindaweni ezahlukahlukene alufani.
Ukungcoliswa kwamanzi
Inkinga enkulu yezemvelo yoLwandle lwaseJapan ukungcoliswa kwamanzi. Uhlelo lwe-hydraulic luthinteka kabi yizimboni ezilandelayo:
- Onjiniyela bamakhemikhali;
- imboni yamakhemikhali;
- umkhakha wamandla kagesi;
- ukusebenza ngensimbi;
- imboni yamalahle.
Ngaphambi kokukhishelwa olwandle, kufanele ihlanzwe ngezinto eziyingozi, izibaseli, ama-phenols, ama-pesticides, izinsimbi ezisindayo nokunye ukungcola.
Akuyona indawo yokugcina ohlwini lwemisebenzi enobungozi ethinta kabi imvelo yoLwandle lwaseJapan ukukhiqizwa nokucutshungulwa kukawoyela. Impilo yezinhlobo eziningi zezitshalo nezilwane, amaketanga okudla aphelele azoncika kulokhu.
Amabhizinisi athululela amanzi angcolile echibini laseZolotoy Bereg, e-Amur nase-Ussuri. Amanzi angcolile avela emadolobheni ahlukahlukene.
Izazi zemvelo zithwele kanzima ukufaka izihlungi zokuhlanza ezidinga ukusetshenziselwa ukwelapha amanzi angcolile ngaphambi kokuba ziwalahle emifuleni nasolwandle.
Ukungcoliswa kwamakhemikhali
Ososayensi bahlole amasampula wamanzi oLwandle lwaseJapan. Imvula ene-asidi nayo ibalulekile. Lezi zinto ziholele ezingeni eliphezulu lokungcola kwedamu.
I-Sea of Japan ingumthombo wemvelo obalulekile osetshenziswe amazwe ahlukahlukene. Izinkinga ezinkulu zemvelo zincike ekutheni abantu balahlela amanzi angalashiwe emifuleni nasolwandle, okudala umonakalo omkhulu ohlelweni lwamanzi, kubulale ulwelwe nempilo yasolwandle. Uma izinhlawulo zokungcola kolwandle, imisebenzi engagunyaziwe yamanye amabhizinisi ingathinteki, lapho-ke ichibi lizoba elingcolile, izinhlanzi nabanye abantu basolwandle bazofela kulo.
