Kubantu abaninzi, isiqalo esihle sisiqingatha sedabi. Umsebenzi wasekuseni uqala emva kwekomityi yekhofi eshushu ... Ngeli xesha, i-caffeine ibophelela kwi-receptor ethile kwingqondo, eyenza ingqondo ingakwazi ukufumana iimpawu "zokukhathala", ngoko inika abantu amandla okunyusa amandla.
Nangona kunjalo, uphando olutsha lukhuphe isilumkiso: ukusetyenziswa kwexesha elide leekomityi zephepha ezilahlayo ukusela ikofu eshushu okanye iziphuzo ezishushu, kuquka ukutya (kushushu) kwiibhokisi zesidlo sasemini ezilahlayo, ziya kuhlawula ixabiso lezempilo.
Kuphononongo olutsha olupapashwe kwi-《 Journal of Hazardous Materials》 (IF=9.038), iqela lophando elivela kwi-Indian Institute of Technology lifumanise ukuba ikofu eshushu okanye ezinye iziselo ezishushu kwiikomityi zephepha ezilahlwayo ngaphakathi kwemizuzu eli-15 Amashumi amawaka ezinto ezinokuba yingozi ziya kukhutshwa kwisiselo, oko kukuthi amasuntswana eplastiki...
Sonke siqhelene neeplastiki ezincinci. Kwiminyaka yakutshanje, kunye nokuveliswa kobuninzi kunye nokusetyenziswa kweeplastiki, ukuxinwa kweeplastiki ezincinci kwindalo kuye kwaqhubeka ukwanda. Ungcoliseko lweplastiki encinci ibe yingxaki yehlabathi jikelele yokusingqongileyo ecaleni kokuphela kwe-ozone, i-asidi yolwandle, kunye nokutshintsha kwemozulu.
Abaphandi bathi ezi plastiki ziphantse zingabonakali zisiba yingozi enkulu kwimpilo yabantu. Ekuqaleni kwalo nyaka, iqela lophando laseMelika lifumene iiplastiki ezincinci kwizitho zomntu okokuqala. Abantu banexhala lokuba olu ngcoliseko luza kubangela umhlaza okanye ubudlolo. Uphononongo lubonise ukuba ungcoliseko lweplastiki encinci lunokubangela ukudumba kwizilwanyana.
Umbhali ohambelana nesifundo, uDkt. Sudha Goel, iSikole seNzululwazi yeNdalo kunye nobuNjineli, i-Indian Institute of Technology, wathi: "Ikomityi yephepha egcwele ikofu eshushu okanye itiye eshushu iya kuhlambalaza i-microplastic layer kwindebe ngaphakathi kwemizuzu eyi-15. It iya kuthomalalisa umlinganiselo weemicrometer ezingama-25 000. La masuntswana akhululwa abe ziziselo ezishushu.
Kuqikelelwa ukuba kunyaka ophelileyo, abavelisi bekomityi yephepha bavelise iikomityi zephepha ezimalunga nama-264 eebhiliyoni, uninzi lwazo zisetyenziselwa iti, ikofu, itshokolethi eshushu, kwanesuphu. Eli nani lilingana neekomityi zephepha ezingama-35 ngomntu ngamnye emhlabeni.
Ukwanda okuqhubekayo kwenani leenkonzo zokuthatha izinto zehlabathi nako kuqhube imfuno yeemveliso ezilahlwayo. Kubomi obuninzi obuxakekileyo kunye nomsebenzi, uku-odola ukuhanjiswa kokutya kuye kwaba yinkqubo yemihla ngemihla kubantu abaninzi. Iibhokisi zesidlo sasemini ezilahlwayo zilahlwa nje zakuba zigqityiwe, kwaye azinampembelelo imbi kokusingqongileyo njengezikhongozeli zeplastiki kunye ne-styrofoam. Nangona kunjalo, uSudha uthe, olu ncedo luza ngexabiso.
Abaphandi bongeze bathi: "Iiplastiki ezincinci zisebenza njengabathwali bezinto ezingcolisayo, ezinje nge-ion, isinyithi esinetyhefu esinetyhefu efana ne-palladium, ichromium kunye ne-cadmium, kunye neekhompawundi zezinto eziphilayo eziyi-hydrophobic kwaye zinokungena kwizilwanyana. iziphumo zempilo zinokuchaphazeleka. Zibi kakhulu."
Ubuchule bokwahlula imichiza buchonge iiplastiki ezincinci kumanzi ashushu. Eyona nto iphazamisayo, uhlalutyo lwefilimu yeplastiki lubonakalise ubukho besinyithi esinzima kwi-lining.
Uyabona ukuba ezi ziphumo zovavanyo zingentla "ziyayothusa", ke ngaba ikhona imveliso enokutshintsha iikomityi zephepha ezigqunywe ngePE?
Impendulo nguewe !YethuIikomityi zephepha ze-EPP,OPB isidlo sasemini ibhokisi series, njl., luphumelele ngokupheleleyo uvavanyo kunye nesiqinisekiso samagunya agunyazisiweyo ahlukeneyo (uvavanyo lokhuseleko lwetyhefu yebhayoloji, uvavanyo lwe-POPs fluorine, uvavanyo oluthile lokufuduka, njl.), kwaye unokuqiniseka ukuba i-pulp ehlaziyiweyo okanye iphepha lingaphinda lisetyenziswe. Beka phambili ukwenza umgquba, qonda izixhobo zokurisayikilisha kwaye usebenzise iplastiki ekhuselekileyo nengenabungozi kokusingqongileyo. Iikomityi zephepha eziveliswe ngayo zinokubuyisela ngokugqibeleleyo iikomityi zephepha ezigqunywe nge-PE.
