Isikhungo sezimboni eziningi noma sezokwelapha sisebenzisa amakhemikhali avuthayo. Amakamelo okuhlola asebenzisa amakhemikhali cishe nsuku zonke. Uketshezi oluvuthayo kanye nezinto ezinobuthi kufanele zigcinwe futhi zifakwe ngokwahlukana ukuze zinciphise ubungozi bokuvuza noma ukusakazeka komlilo.Amakhabethe wesitoreji esivuthayo seYunjshi avuthayo izinqumo ezinhle zokugcina uketshezi oluvuthayo namakhemikhali. Amakhabethe ethu okugcina amakhemikhali ahlukile ngemibala nangosayizi. Siphinde futhi sinikeze insiza yangokwezifiso. Ukuba yisazi sezixazululo zokulawula izixazululo kanye nomswakama, ubuchwepheshe be-Yunboshi bunikeza amakhabethe amakhemikhali, kanye namakhabethe okomisa, njengama-muffs endlebe, amakhasimende emhlabeni wonke. Ubuchwepheshe beYunboshi bugxile ocwaningweni nasekuthuthukisweni kobuchwepheshe bawo bokulawula umswakama ngezimakethe ezahlukahlukene eMkhemisi, ngogesi, i-semiconductor kanye nokupakipha. Besisebenze amakhasimende aqhamuka emazweni angama-64 anjengeRochester - I-USA nase-Inde-India kuyo yonke iminyaka.
