Ukuphepha, ukuthobela imithetho, kanye nesibopho semvelo akuseyona izinto ezikhethwayo kodwa izidingo eziyisisekelo ezihlukanisa abahlinzeki bekhemikhali abanomthwalo wemfanelo futhi bavikela izintshisekelo zamakhasimende abo. Izimo zemakethe zikhombisa ukwanda okuqhubekayo kwesidingo sezinto ezithuthukisiwe ze-formaldehyde ezihlanzekile, ezishukunyiswa ukuthuthukiswa kobuchwepheshe, ukuthuthukiswa kwengqalasizinda, kanye nomzamo womhlaba wonke wokuba nezindlela ezizinzile zezimboni. Ukubambisana nomenzi osemisiwe njengoNGE THU inikeza ukufinyelela hhayi kuphela emikhiqizweni esezingeni eliphezulu kodwa futhi nobuchwepheshe, ukwethembeka kwezinto ezithunyelwayo, kanye nenani lobudlelwano besikhathi eside. Sikhuthaza ochwepheshe bezokuthenga kanye nabenzayo izinqumo zobuchwepheshe ukuthi bahlole ngokucophelela abahlinzeki abangaba khona ngokusekelwe emakhonweni okukhiqiza, izinhlelo zokulawula ikhwalithi, ukuthobela imithetho, kanye nengqalasizinda yokusekelwa kwamakhasimende. Ngemininingwane eyengeziwe mayelana nokucaciswa komkhiqizo, izicelo, kanye nezinketho zokuthola, sicela uvakashele i-IMIKHIQIZO ikhasi noma XHUMANA NATHI ukukhuluma nethimba lethu lobuchwepheshe. Ukwenza ukukhetha okunolwazi ekuphatheni izinto zamakhemikhali kuyisikhathi esihle sokusebenza kahle, ikhwalithi yomkhiqizo, nokukhula kwebhizinisi okuzinzile okuzobuyisa izinzuzo iminyaka ezayo.
