Thaum lub sijhawm txij Lub Ib Hlis 2024 txog Lub Ob Hlis 2024, European Union Txoj Kev Ceeb Toom Ceev Ceev rau Cov Khoom Siv Khoom Noj Tsis Muaj Khoom Noj (RAPEX) tau tshaj tawm ntau qhov xwm txheej ntawm kev tsis ua raws li EU RoHS Cov Lus Qhia thiab POPs cov cai. Cov xwm txheej no feem ntau cuam tshuam txog kev txwv cov khoom xws li di (2-}ethylhexyl) phthalate (DEHP), luv-chain chlorinated paraffins (SCCPs), lead, thiab di-n-butyl phthalate (DBP).
Kev phom sij ntawm Phthalates
▶ Toxicity to the Male Reproductive System: Feem ntau manifested li testicular toxicity. Cov tsos mob muaj xws li mob qog nqaij hlav loj, kev hloov pauv tseem ceeb hauv testosterone concentration, txo cov spermatogenic hlwb, txo qis hauv cov qog nqaij hlav enzyme kev ua, thiab txo cov phev suav.
▶ Kev Toxicity rau Cov Poj Niam Kev Loj Hlob: Cov tshuaj phthalate muaj tshuaj lom rau ntawm lub tsev menyuam thiab zes qe menyuam. Qhov no tuaj yeem ua rau lub voj voog ntev ntev, txo cov qib progesterone, qhov hnyav ntawm lub tsev menyuam, kev hloov pauv ntawm lub voj voog ovulation, thiab ovulation qeeb lossis anovulatory cycles.
▶ Cov txiaj ntsig ntawm Cov Ntshav: Pom qhov txo qis hauv hematocrit, txo qis hauv cov ntsiab lus hemoglobin, thiab qhov tseem ceeb ntawm platelet adhesion.
▶ Teratogenicity: Cov kev tshawb fawb pom tau hais tias raug cov tshuaj phthalate tsawg tsawg ua rau muaj qhov tshwm sim ntawm tus menyuam hauv plab tuag. Kev mob hnyav kuj tuaj yeem ua rau mob plawv, mob raum toxicity, pulmonary toxicity, ua rau tuag taus.
▶ Hepatic Toxicity: Phthalate compounds ua rau oxidative puas tsuaj rau cov proteins, daim siab cell membranes, thiab DNA, thiab tuaj yeem ua rau qia hlwb puas tsuaj.
▶ Carcinogenicity: Ntev raug rau phthalate tebchaw ua rau muaj qhov tshwm sim ntawm malignant qia cell hlav.
Tag nrho cov khoom ntawm lub tuam txhab (J388, JDCH888 series, JDCH999 series) yog benzoe-dawb ib puag ncig plasticizers, tsis muaj DEHP, BBP, DBP, DIBP thiab lwm yam tshuaj lom, thiab tau dhau SGS RoHS thiab lwm yam kev soj ntsuam cov ntawv pov thawj, cov khoom muaj feem xyuam. Cov ntaub ntawv tuaj yeem rub tawm los ntawm kev luam theej duab QR code hauv qab no.
