Kwiikhemikhali ezimalunga nama-350.000 ezithengiswayo kwihlabathi liphela, kuncinci okwaziwayo ngazo ezinokuba yityhefu kwimithambo-luvo kwaye zingonakalisa ingqondo, ngakumbi ngexesha lophuhliso. Ukuza kuthi ga ngoku, iindlela zokuvavanya ezisebenzayo bezingekho, njengoko iindlela eziqhelekileyo zithatha ixesha, zibiza kakhulu, kwaye zihlala ziquka uvavanyo lwezilwanyana kwiimpuku okanye kwiimpuku. Iqela lophando kwiZiko loPhando lweNdalo laseHelmholtz (UFZ) ngoku liphuhlise indlela yokuhlola ephezulu kusetyenziswa iimbumba ze-zebrafish ezithi... Funda ngokugqithisileyo »

Uphononongo oluphambili, olupapashwe ngoJuni 25, 2025, kwiSayensi yezeNdalo kunye ne-Ecotechnology (DOI: 10.1016/j.ese.2025.100589), lulumkisa ngempembelelo enkulu yongcoliseko lweekhemikhali kwizinto eziphilayo zehlabathi. Abaphandi baseTshayina nase-UK babonisa ukuba ungcoliseko lunokunyusa iindawo eziphilayo ziye kwiindawo ezisezantsi apho kungekho mbuyekezo. Ezi ntshukumo zingengomgca, eziye zanda ngenxa yotshintsho lwemozulu kunye nokulahleka kwendawo yokuhlala, zifuna ukuphinda zicinge kwakhona... Funda ngokugqithisileyo »

Iikhemikhali ezingamakhulu amawaka ngoku zithathwa njengetyhefu ebantwini nakwindalo esingqongileyo. Nangona kunjalo, imilinganiselo evela emanzini ifumaneka kuphela kwinxalenye encinci kakhulu yezi khemikhali. Oku ngoku kubonakaliswe zizazinzulu kwiYunivesithi yoBugcisa yaseRhineland-Palatinate yaseKaiserslautern-Landau (RPTU). Zikwabonisa ukuba iingozi zokusingqongileyo kwiikhemikhali ezininzi zinokuvavanywa kuphela kwinqanaba elilinganiselweyo, njengoko sele zisebenza kumanqanaba akwi... Funda ngokugqithisileyo »

Iikhemikhali ezinengxaki azizange zihlolwe ngokwaneleyo kwixesha elidlulileyo, liqukumbela njalo iqela lophando laseTshayina kuphando lwakutshanje. Olu phononongo lubonisa ukuba iikhompawundi ze-organic eziguquguqukayo ezine-chlorine emoyeni zinokuguqulwa zibe yi-polychlorine dibenzo-p-dioxins kunye ne-dibenzofurans ezinobungozi kakhulu kwiinxalenye zothuli lweminerali phantsi kwelanga. Iikhemikhali eziyingozi zihlala zivavanywa kwimigaqo yesizwe neyehlabathi, egxile kakhulu... Funda ngokugqithisileyo »

Iikhemikhali ezine-chlorine azinamsebenzi kubomi bethu bemihla ngemihla. Nangona kunjalo, i-chlorination, ukufakwa kwe-chlorine kwiikhompawundi, kunzima kwaye kudla ngokuba yingozi ebantwini nakwindalo esingqongileyo, kodwa phantse akunakwenzeka ukuyitshintsha. Iqela elikhokelwa yikhemistri uTanja Gulder waseYunivesithi yaseSaarland ngoku lenze uvumbululo oluvula umnyango we-chlorination yeekhompawundi zeekhemikhali ezinobuhlobo nokusingqongileyo, ezifana...
