Ama-microplastics ngokusobala angaphazamisa kakhulu ukusebenza kwama-phagocyte esibindini, okungenani kumagundane. Umphumela uba ukuphazamiseka kokusebenza kwe-metabolic yesitho kanye nokwanda kokugcinwa kwamafutha. Lokhu kuyimiphumela ebalulekile yocwaningo lwaseJalimane nase-Austria oluholwa yi-University of Bonn, olushicilelwe kumagazini i-Nature Metabolism. Ama-phagocyte, aziwa ngokwesayensi ngokuthi ama-macrophage, awuhlobo olukhethekile lomhlophe... Funda kabanzi »

Ukuvuselelwa kabusha kwe-PET plastic kuya ku-levodopa ngama-microbial: ukwenziwa okuqhubekayo kwesidakamizwa sikaParkinson

Abacwaningi basungule inqubo ye-biotechnology eguqula imfucuza yepulasitiki ye-polyethylene terephthalate (PET) ibe yi-levodopa (L-DOPA) – umuthi oyinhloko wokwelapha isifo sikaParkinson. Le ndlela isebenzisa i-Escherichia coli eguquliwe ngokwezakhi zofuzo futhi ithola isivuno esikhulu ngaphansi kwezimo ezithambile nezimanzi. Ithimba, eliholwa nguBenjamin Royer noStephen Wallace, lakha indlela ye-biosynthetic enezinyathelo ezine eguqula i-terephthalic acid (TPA) – i-monomer eyinhloko ye-PET – ibe yi-levodopa nge… Funda kabanzi »

Amahlathi angcoliswa yi-microplastics engena enhlabathini evela emoyeni. Lokhu kuboniswe ocwaningweni olusha olwenziwe yi-TU Darmstadt, olushicilelwe ku-Nature Communications Earth & Environment. Okokuqala ngqa, kukhombisa ukuthi inhlabathi yamahlathi igcina i-micro- kanye ne-nanoplastics, efana nolwandle noma umhlaba wezolimo. Ososayensi be-geoscientific bathole ukuthi izinhlayiya zepulasitiki zingena kakhulu emahlathini ngomoya. Ziyaqoqana... Funda kabanzi »

Abacwaningi eLeibniz University Hannover basungule i-hydrogel entsha emunca futhi yonakalise ama-microplastic emanzini ngokuzimela. Ama-microplastic, angcolisa ulwandle, amachibi, nemifula, abangela ukuvuvukala kanye nokucindezeleka kwe-oxidative ezintweni eziphilayo. Izinhlelo zokuhlunga ezivamile zokususa kwazo ziyabiza futhi zidinga amandla amaningi. Izinto ezintsha, i-hydrogel ye-thermoresponsive enezinhlayiya ze-organosilicate ezinezimbobo kanye ne-photocatalyst, isebenza ngokuzimela. Icwila emanzini angcolile... Funda kabanzi »

Izingxoxo ze-UN ngo-Agasti 2025 kungenzeka ukuthi zaphakamisa ukuqwashisa ngenkinga yomhlaba wonke yepulasitiki, okungenani okwesikhashana, kodwa isintu sisekude kakhulu nesixazululo somhlaba wonke. Ngaphandle koshintsho olukhulu, inani kanye nobuthi bepulasitiki emvelweni, kanye nakubantu nasezilwaneni, kuzoqhubeka nokukhula ngokushesha. Siqoqe izibalo namaqiniso athile... Funda kabanzi »

Ochwepheshe bezempilo banxusa isivumelwano se-UN esinombono ojulile sokuvikela impilo yabantu kumapulasitiki anobuthi. Ngaphambi kwezingxoxo zoHlelo Lwezemvelo lwe-UN eGeneva ngo-Agasti, babiza umhleli we-World Health Organization (WHO) ukuthi kuqedwe ukusetshenziswa kwamakhemikhali ayingozi kumapulasitiki, kuncishiswe ukukhiqizwa kwepulasitiki, kanye nokushintsha ekuphathweni kwemfucuza kanye nokusetshenziswa kabusha njengezixazululo eziyinhloko.

I-Transpolar Drift, umsinga omkhulu wolwandle, iyindlela ebalulekile yokuthutha amanzi ahlanzekile nezinto zomhlaba e-Arctic Ocean. Lo msinga womhlaba awugcini nje ngokwakha izindawo zemvelo ezisemaceleni kodwa futhi uthinta nokugeleza kolwandle emhlabeni jikelele. Ithimba locwaningo lwamazwe ngamazwe eliholwa yi-University of Bristol, kanye nabalingani bamazwe ngamazwe okuhlanganisa i-Kiel University (CAU) kanye ne-Alfred Wegener Institute, i-Helmholtz Centre for Polar and Marine Research, manje seli...

Ama-nitrate, izibulala-zinambuzane, izinsimbi, ipulasitiki – inhlabathi yezolimo ivame ukuqukethe ukungcola. Ingabe zikhona izixazululo eziqhubekayo nezingathathi hlangothi kwesimo sezulu zokuthuthukisa nokukhuthaza impilo yenhlabathi ezindaweni zezolimo? Yebo, kusho ithimba locwaningo e-UFZ (Helmholtz Centre for Environmental Research). Izinhlobo ezithile zezitshalo zingasetshenziswa njengezitshalo zokumboza ze-phytoremediation, okungukuthi, ukususa ukungcola enhlabathini. Izitshalo zokumboza yizitshalo ezikhuliswe phakathi kwezitshalo ezimbili eziyinhloko… Funda kabanzi »

Ukuthi izinhlayiya ezincane zepulasitiki zingena kanjani emkhathini kuwumbuzo obalulekile, ngoba ngokusho kwezifundo eziningi zakamuva, amapulasitiki amancane emoyeni abeka impilo engcupheni. Besebenzisa imodeli yomhlaba wonke yokuthutha izinto zamakhemikhali, abacwaningi bakhombisile ukuthi, ngokuphambene nalokho okushiwo ngaphambilini, ulwandle aluwona umthombo omkhulu wamapulasitiki amancane emkhathini, kodwa kunalokho luyisinki esikhulu.
