Diethell phthalate,Yaziwa nangokuthi i-PEP kanye ne-CAS Inombolo 84-66-2, iwuketshezi olungenamibala nolungenamphundla oluvame ukusetshenziswa njengesesimo epulasitiki emikhiqizweni ehlukahlukene yabathengi. Kusetshenziswa kabanzi ekukhiqizweni kwezimonyo, imikhiqizo yokunakekelwa komuntu siqu, amakha, kanye nemithi yezemithi. Kodwa-ke, kube nokukhathazeka okukhulayo kanye nenkulumompikiswano ngemiphumela engaba yingozi ye-diethell perthalate empilweni yezempilo nemvelo.
Ingabe i-diethell phthalate iyingozi?
Umbuzo wokuthidiethell phthalatekuyingozi kube yisihloko sengxoxo nokucwaninga okuningi. UDiethyl perthalate uhlukaniswa njengo-Phthalate Ester, iqembu lamakhemikhali abelokhu lihlolisiswa ngenxa yemiphumela yawo emibi yempilo yabantu. Ucwaningo luphakamise ukuthi ukuvezwa ku-diethell phthalate kungaxhunyaniswa nezinkinga ezahlukahlukene zezempilo, kufaka phakathi ubuthi bokuzala nokuthuthuka, ukuphazamiseka kwe-endocrine, kanye nemiphumela ye-carcinogenic engaba khona.
Enye yezinto ezimayelana nokukhathazeka okuzungezilediethell phthalateingabe amandla ayo ukuphazamisa uhlelo lwe-endocrine. Abaphazamisi be-Endocrine bangamakhemikhali angaphazamisa ibhalansi ye-hormonal yomzimba, eholela emiphumeleni emibi yezempilo. Ucwaningo luveze ukuthi i-diethell perthalate ingalingisa noma iphazamise umsebenzi wama-hormone emzimbeni, ukukhulisa ukukhathazeka ngomthelela wayo ngempumelelo yokuzala nentuthuko, ikakhulukazi ezinganeni nabesifazane abakhulelwe.
Ngaphezu kwalokho, kunobufakazi bokuphakamisa lokhodiethell phthalateingaba nemiphumela emibi ohlelweni lokuzala. Ucwaningo luxhumeke ekuchayweni kwezifo ezivela kuma-phthalates, kufaka phakathi i-diethel phthalate, ngekhwalithi yesidoda enciphile, amazinga we-hormone aguquliwe, kanye nokungahambi kahle kokuzala. Lokhu okutholakele kukhulise ukukhathazeka ngomthelela ongaba khona we-diethell perthalate ekuvuthweni nasekuzalweni impilo.
Ngaphezu kwemiphumela yayo engaba khona empilweni yabantu, kukhona nezinkinga ngomthelela wezemvelo we-diethell perthalate. Njengamakhemikhali asetshenziswa kabanzi emikhiqizweni yabathengi, i-diethell perthalate inamandla okufaka imvelo ngezindlela ezahlukahlukene, kufaka phakathi izinqubo zokukhiqiza, ukusetshenziswa komkhiqizo, nokulahlwa. Lapho ekhishwe emvelweni, uDiethely phthalate angaphikelela futhi aqongelele, abhale izingozi ezingaba khona ku-Ecosystems nasezilwaneni zasendle.
Ngaphandle kwalokhu okukhathazayo, kubalulekile ukuqaphela ukuthi ama-ejensi okulawula nezinhlangano athathe izinyathelo zokubhekana nezingozi ezingaba khona ezihambisana ne-diethel perthalate. Ezifundeni eziningi, kufaka phakathi i-European Union kanye ne-United States, uDiethely phthalate ungaphansi kwemithetho nemikhawulo okuhloswe ngayo ukunciphisa ukusetshenziswa kwayo emikhawulweni ethile nasekuqinisekiseni imikhawulo ephephile.
Naphezu kokukhathazeka okuzungezilediethell phthalate, iyaqhubeka nokusetshenziswa emikhiqizweni ehlukahlukene yabathengi ngenxa yokusebenza kwayo njenge-Plistic. Kuma-COSMETICS kanye nemboni yokunakekelwa komuntu siqu, i-diethell perthalate isetshenziswa kakhulu emakhaleni, izipikili zezipikili, nezithombo zezinwele ukuthuthukisa ukuguquguquka nokuqina kwemikhiqizo. Iphinde isetshenziswe ekwakhiweni kwemithi ukuthuthukisa i-solubility yezithako ezisebenzayo.
Ukuphendula ukukhathazeka mayelanadiethell phthalate, Abakhiqizi abaningi bebelokhu behlola amanye amapulasitiki nezithako zokunciphisa noma ukuqeda ukusetshenziswa kwezifo ezisebenza ngemikhiqizo yabo. Lokhu kuholele ekuthuthukisweni kokwakheka kwamahhala kwe-perthalate nokusetshenziswa kwamanye ama-spistizes abhekwa njengokuphephile kwempilo yabantu kanye nemvelo.
Ekuphetheni, umbuzo wokuthidiethell phthalateIlimaza inkinga eyinkimbinkimbi futhi eqhubekayo edinga ukucubungula ngokucophelela kobufakazi obukhona besayensi nezindlela zokulawula. Ngenkathi i-diethell phthalate isetshenziswe kabanzi njengepulasitiki emikhiqizweni yabathengi, ukukhathazeka ngemiphumela yayo engaba khona ngempilo yabantu futhi imvelo iye yathuthumela ukwanda kokuhlolisiswa kanye nokwakhiwa kwezinye izindlela. Njengokuqonda kwezingozi ezingaba khona ezihambisana ne-diethell perthalate ziyaqhubeka, kubalulekile ukuba abakhiqizi, abalawuli kanye nabathengi ukuhlala unolwazi futhi bakwazi ukukwazi izinqumo ezinolwazi ngokusetshenziswa kwalemikhiqizo.
