I-Diethyl phthalate,eyaziwa nangokuthi i-DEP kanye nenombolo ye-CAS 84-66-2, iwuketshezi olungenambala nolungenaphunga oluvame ukusetshenziswa njenge-plasticizer ezinhlobonhlobo zemikhiqizo yabathengi. Isetshenziswa kabanzi ekukhiqizeni izimonyo, imikhiqizo yokunakekelwa komuntu siqu, amakha, kanye nemithi. Kodwa-ke, kube nokukhathazeka okukhulayo kanye nenkulumompikiswano mayelana nemiphumela eyingozi engaba khona ye-diethyl phthalate empilweni yabantu kanye nemvelo.
Ingabe i-Diethyl Phthalate Iyingozi?
Umbuzo wokuthii-diethyl phthalatekuyingozi kube yindaba yezingxoxo nocwaningo oluningi. I-Diethyl phthalate ihlukaniswa njenge-phthalate ester, iqembu lamakhemikhali abelokhu ehlolisiswa ngenxa yemiphumela yawo emibi engaba khona empilweni yabantu. Ucwaningo luye lwaphakamisa ukuthi ukuchayeka ku-diethyl phthalate kungase kuxhunywe ezindabeni ezihlukahlukene zezempilo, okuhlanganisa ubuthi bokuzala nokuthuthuka, ukuphazamiseka kwe-endocrine, kanye nemiphumela engaba khona ye-carcinogenic.
Enye yezinto ezikhathazayo eziyinhloko ezizungezilei-diethyl phthalateamandla ayo okuphazamisa uhlelo lwe-endocrine. Iziphazamisi ze-Endocrine zingamakhemikhali angaphazamisa ukulingana kwamahomoni omzimba, okungase kuholele emiphumeleni yezempilo engemihle. Ucwaningo luveze ukuthi i-diethyl phthalate ingase ilingise noma iphazamise ukusebenza kwamahomoni emzimbeni, iphakamise ukukhathazeka ngomthelela wayo empilweni yokuzala nokuthuthuka, ikakhulukazi ezinganeni nakwabesifazane abakhulelwe.
Ngaphezu kwalokho, kunobufakazi obusikisela lokhoi-diethyl phthalateingase ibe nemiphumela emibi ohlelweni lokuzala. Ucwaningo luye lwaxhumanisa ukuchayeka kuma-phthalates, okuhlanganisa i-diethyl phthalate, enekhwalithi yesidoda enciphile, amazinga amahomoni ashintshile, kanye nokungajwayelekile kokuzala. Lokhu okutholakele kuphakamise ukukhathazeka ngomthelela ongaba khona we-diethyl phthalate ekuzaleni nempilo yokuzala.
Ngaphezu kwemiphumela engaba khona empilweni yomuntu, kukhona nokukhathazeka mayelana nomthelela wemvelo we-diethyl phthalate. Njengekhemikhali esetshenziswa kakhulu emikhiqizweni yabathengi, i-diethyl phthalate inamandla okungena emvelweni ngezindlela ezahlukahlukene, okubandakanya izinqubo zokukhiqiza, ukusetshenziswa komkhiqizo, kanye nokulahlwa. Uma isikhishelwe endaweni ezungezile, i-diethyl phthalate ingaphikelela futhi iqongelele, ibeke ubungozi obungaba khona kuma-ecosystem kanye nezilwane zasendle.
Naphezu kwalokhu kukhathazeka, kubalulekile ukuqaphela ukuthi izinhlangano ezilawulayo nezinhlangano zithathe izinyathelo zokubhekana nezingozi ezingase zibe khona ezihlobene ne-diethyl phthalate. Ezifundeni eziningi, okuhlanganisa i-European Union kanye ne-United States, i-diethyl phthalate ingaphansi kwemithetho nemikhawulo ehloselwe ukukhawulela ukusetshenziswa kwayo emikhiqizweni ethile kanye nokuqinisekisa ukuthi amazinga okuchayeka angaphakathi kwemikhawulo ephephile.
Naphezu kokukhathazeka okuzungezilei-diethyl phthalate, iyaqhubeka nokusetshenziswa ezinhlobonhlobo zemikhiqizo yabathengi ngenxa yokusebenza kwayo njenge-plasticizer. Embonini yezimonyo nokunakekelwa komuntu siqu, i-diethyl phthalate ivame ukusetshenziswa kumakha, ukupholisha izinzipho, nezifutho zezinwele ukuthuthukisa ukuguquguquka nokuqina kwemikhiqizo. Ibuye isetshenziswe ekwenziweni kwemithi ukuthuthukisa ukunyibilika kwezithako ezisebenzayo.
Ekuphenduleni ukukhathazeka mayelanai-diethyl phthalate, abakhiqizi abaningi bebelokhu behlola amanye ama-plasticizers kanye nezithako zokunciphisa noma ukuqeda ukusetshenziswa kwama-phthalates emikhiqizweni yabo. Lokhu kuye kwaholela ekwakhiweni kokwakheka kwamahhala kwe-phthalate kanye nokusetshenziswa kwamanye ama-plasticizer abhekwa njengaphephile empilweni yomuntu kanye nemvelo.
Sengiphetha, umbuzo wokuthi ngabei-diethyl phthalatekuyingozi udaba oluyinkimbinkimbi futhi oluqhubekayo oludinga ukucutshungulwa ngokucophelela kobufakazi besayensi obukhona kanye nezinyathelo zokulawula. Nakuba i-diethyl phthalate isetshenziswe kabanzi njenge-plasticizer emikhiqizweni yabathengi, ukukhathazeka mayelana nemiphumela yayo engaba khona empilweni yabantu kanye nemvelo kuye kwabangela ukucutshungulwa okukhulayo kanye nokuthuthukiswa kwezinye izinhlobo zokwakheka. Njengoba ukuqonda kwezingozi ezingaba khona ezihlobene ne-diethyl phthalate kuqhubeka nokuvela, kubalulekile kubakhiqizi, abalawuli, nabathengi ukuthi bahlale benolwazi futhi benze izinqumo ezinolwazi mayelana nokusetshenziswa kwaleli khemikhali emikhiqizweni.
