I-Diethyl phthalate,eyaziwa ngokuba yi-DEP kunye nenombolo ye-CAS 84-66-2, ngulwelo olungenambala kunye nevumba eliqhelekileyo elisetyenziswa njenge-plasticizer kuluhlu olubanzi lweemveliso zabathengi. Isetyenziswa kakhulu kwimveliso yezithambiso, iimveliso zokhathalelo lomntu, iziqholo, kunye namayeza. Nangona kunjalo, kukho inkxalabo ekhulayo kunye nengxoxo malunga neziphumo ezinobungozi ze-diethyl phthalate kwimpilo yabantu kunye nokusingqongileyo.
Ngaba i-Diethyl Phthalate Inobungozi?
Umbuzo wokubai-diethyl phthalateiyingozi ibe ngumxholo wengxoxo kunye nophando oluninzi. I-Diethyl phthalate ihlelwa njenge-phthalate ester, iqela leekhemikhali eziye zahlolwa ngenxa yemiphumo emibi enokubakho kwimpilo yabantu. Uphononongo lucebise ukuba ukuvezwa kwi-diethyl phthalate kunokunxulunyaniswa nemicimbi eyahlukeneyo yezempilo, kubandakanya netyhefu yokuzala kunye nophuhliso, ukuphazamiseka kwe-endocrine, kunye neziphumo ezinokubakho ze-carcinogenic.
Enye yezinto eziphambili ezixhalabisayoi-diethyl phthalateamandla ayo okuphazamisa inkqubo ye-endocrine. Iziphazamisi ze-Endocrine ziikhemikhali ezinokuphazamisa ibhalansi yehomoni yomzimba, enokukhokelela kwiziphumo ezibi zempilo. Uphando lubonise ukuba i-diethyl phthalate inokulinganisa okanye iphazamise ukusebenza kweehomoni emzimbeni, iphakamisa inkxalabo malunga nefuthe layo kwimpilo yokuzala kunye nophuhliso, ngakumbi kubantwana kunye nabasetyhini abakhulelweyo.
Ngaphezu koko, kukho ubungqina obubonisa ukubai-diethyl phthalateinokuba nemiphumo emibi kwinkqubo yokuzala. Uphononongo lunxibelelene nokuvezwa kwi-phthalates, kubandakanya i-diethyl phthalate, kunye nomgangatho oncitshisiweyo wesidoda, amanqanaba ehomoni atshintshileyo, kunye nokungaqhelekanga kokuzala. Ezi ziphumo ziphakamise iinkxalabo malunga nefuthe elinokubakho le-diethyl phthalate ekuchumeni kunye nempilo yokuzala.
Ukongeza kwimiphumo enokubakho kwimpilo yabantu, kukwakho iinkxalabo malunga nefuthe lemo engqongileyo ye-diethyl phthalate. Njengekhemikhali esetyenziswa ngokubanzi kwiimveliso zabathengi, i-diethyl phthalate inamandla okungena kwimo engqongileyo ngeendlela ezahlukeneyo, kubandakanya iinkqubo zokuvelisa, ukusetyenziswa kwemveliso, kunye nokulahlwa. Nje ukuba ikhutshelwe kwindalo esingqongileyo, i-diethyl phthalate inokuqhubeka kwaye iqokelele, ibeka imingcipheko enokubakho kwi-ikhosistim kunye nezilwanyana zasendle.
Nangona ezi nkxalabo, kubalulekile ukuba uqaphele ukuba ii-arhente ezilawulayo kunye nemibutho ithathe amanyathelo okujongana neengozi ezinokuthi zidibene ne-diethyl phthalate. Kwimimandla emininzi, kubandakanywa i-European Union kunye ne-United States, i-diethyl phthalate ixhomekeke kwimimiselo kunye nezithintelo ezijoliswe ekunciphiseni ukusetyenziswa kwayo kwiimveliso ezithile kunye nokuqinisekisa ukuba amanqanaba okuvezwa angaphakathi kwemida ekhuselekileyo.
Nangona kukho iinkxalabo ezingqongileyoi-diethyl phthalate, iyaqhubeka isetyenziselwa uluhlu olubanzi lweemveliso zabathengi ngenxa yokusebenza kwayo njengeplastiki. Kwizimonyo kunye neshishini lokhathalelo lomntu, i-diethyl phthalate iqhele ukusetyenziswa kwiziqhumiso, iipolishe zenzipho, kunye nezitshizi zeenwele ukuphucula ukuguquguquka kunye nokuqina kweemveliso. Ikwasetyenziswa ekuxutyweni kwamachiza ukunyusa ukunyibilika kwezithako ezisebenzayo.
Ukuphendula iinkxalabo malungai-diethyl phthalate, abaninzi abavelisi baye bahlola ezinye iiplastiki kunye nezithako zokunciphisa okanye ukuphelisa ukusetyenziswa kwe-phthalates kwiimveliso zabo. Oku kuye kwakhokelela ekuphuhlisweni kwe-phthalate-free formulations kunye nokusetyenziswa kwezinye iiplastiki ezithathwa njengezikhuselekileyo kwimpilo yabantu kunye nokusingqongileyo.
Ukuqukumbela, umbuzo wokubai-diethyl phthalatekuyingozi ngumba ontsonkothileyo noqhubekayo ofuna ukuqwalaselwa ngononophelo ubungqina obukhoyo benzululwazi kunye namanyathelo olawulo. Ngelixa i-diethyl phthalate isetyenziswe ngokubanzi njengeplastiki kwiimveliso zabathengi, iinkxalabo malunga nemiphumo enokubakho kwimpilo yabantu kunye nokusingqongileyo kuye kwabangela ukwanda kokuhlolwa kunye nokuphuhliswa kwezinye iindlela zokuxutywa. Njengoko ukuqonda kweengozi ezinokubakho ezinxulumene ne-diethyl phthalate ziqhubeka nokuguquka, kubalulekile ukuba abavelisi, abalawuli, kunye nabathengi bahlale benolwazi kwaye benze izigqibo ezinolwazi malunga nokusetyenziswa kwale khemikhali kwiimveliso.
