Xinhua News Agency, Beijing, January 10, News Special News Media Sida laga soo xigtay mareegaha "Wararka Caafimaadka Maanta" ee Maraykanka iyo website-ka rasmiga ah ee Qaramada Midoobay, microplastics waa "meel walba", laakiin qasab maaha inay khatar ku yihiin caafimaadka aadanaha. .Maria Nella, oo ah madaxa waaxda caafimaadka dadweynaha, deegaanka iyo go'aaminta bulshada ee WHO, ayaa tiri: "Waxaan ogaanay in maaddadan ay ku jirto deegaanka badda, cuntada, hawada iyo biyaha la cabbo.Marka loo eego macluumaadka xaddidan ee aan hayno, biyaha la cabbo Microplastics ee Shiinaha uma muuqdaan inay halis caafimaad ku yihiin heerarka hadda jira.Si kastaba ha ahaatee, waxaan si degdeg ah ugu baahanahay inaan wax badan ka ogaano saameynta microplastics-ka ay ku leeyihiin caafimaadka."
Waa maxay microplastics?
Qurub caag ah oo dhexroor ka yar 5 mm ayaa guud ahaan loo yaqaan "microplastics" (qurub dhexroor ka yar 100 nanometer ama xataa ka yar fayrusyada waxaa sidoo kale loo yaqaan "nanoplastics").Baaxadda yar waxay la macno tahay inay si fudud ugu dabaalan karaan webiyada iyo biyaha.
Xaggee ka yimaadeen?
Ugu horreyntii, qaybo waaweyn oo balaastig ah ayaa jejebi doona oo burburi doona wakhti ka dib waxayna noqdaan microplastics;Qaar ka mid ah alaabooyinka warshadaha laftoodu waxay ka kooban yihiin balaastiigyo yar-yar: Nabarrada microplastic-ku waxay ku badan yihiin alaabta sida daawada cadayga iyo nadiifiyeyaasha wejiga.Daadinta fiber-ka ee alaabada faybarka kiimikaad ee nolol maalmeedka iyo qashinka ka yimaada is jiid jiidka taayirka ayaa sidoo kale ka mid ah ilaha.Maraykanku waxa uu hore u mamnuucay ku darista microplastics ee daryeelka maqaarka iyo alaabta daryeelka shakhsi ahaaneed sanadka 2015.
Halkee baad ugu badan isugu keentaa?
Microplastics-ka waxaa lagu qaadi karaa badweynta biyaha wasakhda ah oo ay liqi karaan xayawaanka badda.Muddo ka dib, tani waxay keeni kartaa in microplastics ay ku ururaan xayawaankan.Sida laga soo xigtay xogta ururka "Balaastigga" ururka, in ka badan 8 milyan oo tan oo baco ah ayaa qulqulaya badda sannad kasta.
Daraasad la sameeyay 2020 ayaa tijaabisay 5 nooc oo kala duwan oo cuntooyinka badda ah waxaana lagu ogaaday in muunad kasta ay ka kooban tahay microplastics.Isla sannadkaas, cilmi-baadhis lagu tijaabiyey laba nooc oo kalluun ah oo ku jira webi, ayaa lagu ogaaday in 100% saamiga tijaabada ah ay ku jiraan microplastics.Microplastics ayaa si qarsoodi ah u soo galay liiskayaga.
Microplastics ayaa kor u qulquli doona silsiladda cuntada.Marka uu xayawaanku u dhawaado xagga sare ee silsiladda cuntada, waa ay sii kordheysaa suurtogalnimada in la qaato microplastics.
Maxay WHO tiri?
2019, Ururka Caafimaadka Adduunka ayaa soo koobay cilmi-baaristii ugu dambeysay ee saameynta wasakhowga microplastics-ka ee aadanaha markii ugu horreysay.Gabagabada ayaa ah in microplastics-ku ay yihiin "meel walba", laakiin qasab maaha inay khatar ku yihiin caafimaadka aadanaha.Maria Nella, oo ah madaxa waaxda caafimaadka dadweynaha, deegaanka iyo go'aaminta bulshada ee WHO, ayaa tiri: "Waxaan ogaanay in maaddadan ay ku jirto deegaanka badda, cuntada, hawada iyo biyaha la cabbo.Marka loo eego macluumaadka xaddidan ee aan hayno, biyaha la cabbo Microplastics-ka Shiinaha uma muuqdaan inay halis caafimaad u yihiin heerka hadda jira.Si kastaba ha ahaatee, waxaan si degdeg ah ugu baahanahay inaan wax badan ka ogaano saameynta microplastics-ka ay ku leeyihiin caafimaadka."WHO waxay aaminsan tahay in microplastics-ka dhexroorkoodu ka weyn yahay 150 microns aysan u badnayn in uu nuugo jidhka bini'aadamka.Qaadashada walxaha yaryar waxay u badan tahay inay aad u yar yihiin.Intaa waxaa dheer, microplastics-ka ku jira biyaha la cabbo inta badan waxay ka tirsan yihiin laba nooc oo maaddooyin ah - PET iyo polypropylene.
