Kumakhemikhali angaba ngu-350.000 atholakala kwezentengiselwano emhlabeni wonke, kuncane okwaziwayo ngawo okungaba yingozi engqondweni futhi okungalimaza ubuchopho, ikakhulukazi ngesikhathi sokuthuthukiswa. Kuze kube manje, izindlela zokuhlola ezisebenzayo bezingekho, njengoba izindlela ezivamile zidla isikhathi, zibiza kakhulu, futhi zivame ukuhilela ukuhlolwa kwezilwane kumagundane noma emagundwini. Ithimba locwaningo eHelmholtz Centre for Environmental Research (UFZ) manje selisungule indlela yokuhlola ephezulu esebenzisa imibungu ye-zebrafish... Funda kabanzi »

Ucwaningo oluqavile, olwanyatheliswa ngoJuni 25, 2025, ku-Environmental Science and Ecotechnology (DOI: 10.1016/j.ese.2025.100589), luxwayisa ngomthelela omkhulu wokungcola kwamakhemikhali ezinhlobonhlobo zezinto eziphilayo emhlabeni jikelele. Abacwaningi baseShayina nase-UK babonisa ukuthi ukungcola kungasunduza izimiso zemvelo ziye ezindaweni lapho kungekho khona ukubuya. Lezi zinguquko ezingezona eziqondile, ezibhebhethekiswa ukuguquka kwesimo sezulu nokulahlekelwa yindawo yokuhlala, zidinga ukucabanga kabusha okuyisisekelo... Funda kabanzi »

Amakhemikhali ayizinkulungwane eziningana manje abhekwa njenganobuthi kubantu kanye nemvelo. Kodwa-ke, izilinganiso ezivela emanzini zitholakala engxenyeni encane kakhulu yala makhemikhali. Lokhu sekuboniswe ososayensi eRhineland-Palatinate Technical University yaseKaiserslautern-Landau (RPTU). Ziphinde zibonise ukuthi izingozi zemvelo zamakhemikhali amaningana zingahlolwa kuphela ngezinga elilinganiselwe, njengoba sezivele zisebenza kahle ekugxilweni ku... Funda kabanzi »

Amakhemikhali ayinkinga awazange ahlolwe ngokwanele esikhathini esidlule, kuphetha ithimba locwaningo laseShayina ocwaningweni lwakamuva. Ucwaningo lubonisa ukuthi amakhemikhali e-organic aguquguqukayo ane-chlorine emoyeni angaguqulwa abe ama-dibenzo-p-dioxin ane-polychlorine anobuthi obukhulu kanye nama-dibenzofuran ezinhlayiyeni zothuli lwamaminerali ngaphansi kokukhanya kwelanga. Amakhemikhali ayingozi avame ukuhlolwa emithethweni kazwelonke neyamazwe ngamazwe, egxile kakhulu... Funda kabanzi »

Amakhemikhali aqukethe i-chlorine abalulekile empilweni yethu yansuku zonke. Kodwa-ke, i-chlorination, ukufakwa kwe-chlorine kuma-compounds, kunzima futhi kuvame ukuba yingozi kubantu kanye nemvelo, kodwa cishe akunakwenzeka ukuyishintsha. Ithimba eliholwa ngusokhemisi uTanja Gulder waseSaarland University manje selithole into evula umnyango we-chlorination yama-compounds amakhemikhali anobungani nemvelo, njenge... Funda kabanzi »
