Iibhetri ezingenazinkunkuma zemercury akunyanzelekanga ukuba ziphinde zisetyenziswe kwaye kujongwane nazo ngamnye, ngaba zingakwazi ukulahla zonke ngenkunkuma yobomi? Unyaka ka-Chen Bai, ibakala lesihlanu lesitalato sase-Youfu West, Ndaliphikisa le mbono. I-5th Nanjing Youth "iSayensi", ebanjwe yiKomiti kaMasipala, ibambe iphepha elincinci kweso siganeko, kwaye abantwana babhala intshiseko enkulu. Ilahleko yeebhetri ingozi "encinci"? Chen Bai, ukhumbula ukuba utitshala wathi kwiklasi yesayensi: ibhetri enye ibolile emhlabeni, enokwenza umhlaba osisikwemitha esi-1 usebenzise ngokusisigxina ixabiso; ibhetri yeqhosha inokubangela iitoni ezingama-600 zongcoliseko lwamanzi.

Ngoko ke, uye wahlala ekholelwa ukuba ibhetri yenkunkuma inomonakalo omkhulu kwindalo. Kodwa uthe akujonga kweli phephandaba, wafumanisa ukuba ezinye iingcali zikholelwa ukuba ingozi yenkunkuma yebhetri incinci, kwaye namagosa athi iibhetri ezingenankunkuma akunyanzelekanga ukuba ziphinde zisetyenziswe kwaye zijongane nazo, zinokulahla inkunkuma yasekhaya. Kwiimbono ezinjalo, i-Chen Bai ayiqatshelwa, kwaye ngokwenza iimvavanyo.

“Ndifuna ukufunda ngokuntshula kwembewu ngokusebenzisa iibhetri ezilahliweyo, abantu abaninzi mabawuqonde umonakalo weebhetri zenkunkuma. "Uvavanyo lubonisa ukuba ibhetri ye-mercury-free nayo iyingozi kwi-Chen Bai iminyaka: izinga lokuntshula kwembewu yembotyi emanzini acocekileyo yi-100%, kwinqanaba elithile lokuhluma kwembewu yembotyi eluhlaza kulwelo oluvuzayo olubhalwe" i-mercury ephantsi ye-zinc manganese ", kwiqondo elithile lokuntshula kwembewu yembotyi ye-mung mercury ebhalwe "imbewu ye-bean ye-mung ebhalwe kwibhetri I-100%, kodwa imbewu ekucoceni iphelile, kwaye ukuhluma kwembewu kuya kumisa ukukhula, kwaye ekugqibeleni isikhunta, i-necrosis. Oku kunokuqukunjelwa ngokuba iibhetri eziluncedo ezingenametyhuri ephantsi ziyingozi ekuntshuleni nasekukhuleni kwembewu yeembotyi zemung.

Ngokusebenzisa imifuniselo, nceda ubuze utitshala, ufumane ulwazi olufanelekileyo, u-Chen Bai ukholelwa ukuba nayiphi na inkcazo ebaxayo okanye ecutha ibhetri eyingozi ayiyonzululwazi. “Sinokuqonda okuthile ngeengozi zeebhetri ezisetyenzisiweyo, kodwa akukho nto isebenzayo. "I" iNzululwazi encinci uGqr.

"IKomiti eQuquzelelayo ivavanye amaphepha angama-74 abalaseleyo, abandakanya iinkalo ezininzi ezinje ngoluntu, ubomi kunye nezidalwa. Kuxelwa ukuba abadlali abanomsebenzi omhle kula maphepha amancinci kunye nempendulo baya kufumana isihloko esihloniphekileyo se-5th Nanjing Juvenile "Isayensi encinci uDkt.".
