Njengoba umhlaba ujwayela imiphumela yobhubhane lomhlaba wonke, kukhona okungenani izinto ezithile okungathenjelwa kuzo ukuthi zingashintshi.
Umnotho waseChina owawudonsa kanzima ekuqaleni kwalolu bhubhane, usululeme kakhulu, njengoba umsebenzi wokukhiqiza waseChina usunyukele ngenyanga yesi-9 ilandelana ngokusho kweNational Bureau of Statistics.
Ukukhiqizwa kwama-PCB asekhaya aseShayina njengamanje kudlula imiyalo yokuthekelisa ezimbonini eziningi futhi kuhambisana nokukhuphuka kwentengo yezinto ezingavuthiwe ezingaphezu kwama-35% kwezinye izimo, abakhiqizi be-PCB manje sebezimisele ukudlulisa lezi zindleko ezikhuphukile kumakhasimende, ababengafuni ukukwenza ngesikhathi izigaba zokuqala zobhubhane.
Njengoba ama-oda okuthunyelwa kwamanye amazwe eqala ukuqoqwa umthamo otholakalayo uyaqhubeka nokunciphisa ukubeka ingcindezi eyengeziwe kumaketango wokuhlinzeka ngezinto ezibonakalayo, okuvumela abakhiqizi bempahla eluhlaza ukuthi bakhokhise amanye amaphrimiyamu.
Igolide lihlala liwuthango lokungaqiniseki kwezomnotho emhlabeni wonke, njengoba insimbi eyigugu idlondlobala yafinyelela ezingeni eliphezulu emlandweni, ukusebenza okuphinde kwaphindeka kabili izindleko zensimbi kule minyaka emihlanu edlule.
Izindleko zobuchwepheshe be-PCB azivikeleki, njengoba izindleko zokuqedela indawo ye-ENIG zinyukile kubo bonke ubuchwepheshe, umthelela walokhu kukhula uzwakala kakhulu kumikhiqizo yokubalwa kongqimba ephansi njengoba i-% yokwenyuka ilingana ngokuphambene nenani lezendlalelo.
Ijubane lokubuyela emuva komnotho waseShayina lizwakala emhlabeni wonke, njengoba iDola laseMelika lehla ngo-6% uma liqhathaniswa ne-RMB kusukela ngoJanuwari 2020. Amafekthri e-PCB atholakala ngedola emalini ekhokhiswayo kufanele abhekane nokuhunyushwa kwemali yakwamanye amazwe njengoba izindleko zabo zomsebenzi zikhuphuka. ikhokhwe ngemali yendawo.
Ngokunyuka kwezinto zokusetshenziswa okungenzeka kuqhubeke kuze kube semva kukaNyaka Omusha WaseShayina kanye nokukhula okuqhubekayo kwempahla edayiswa emhlabeni wonke, imakethe manje isifinyelele eqophelweni lapho amanani okukhiphayo e-PCB enyuka abe sezingeni elingenakusimama ukuze amafekthri aliquke.
