TAILIEUCHUNG - Determination of phthalate esters in children’s toys

The studied method was a reliable, rapid, easy and cheap method and permitted to determine the restricted phthalates in plastic toys in compliance with European Regulation (No 1907/2006). The method was applied to determine phthalates in 20 toys in HoChiMinh city, Vietnam. Phthalates were found in almost soft PVC toys with high concentrations. | TAÏP CHÍ PHAÙT TRIEÅN KH&CN, TAÄP 19, SOÁ K5- 2016 Determination of phthalate esters in children’s toys Tran Thi Kieu Anh Luong Trong Ton Tran Ngoc Hoa Pham Minh Trang Ho Chi Minh City University of Technology, VNU-HCM (Manuscript Received on June 10th, 2016, Manuscript Revised August 12th, 2016) ABSTRACT A validated analytical method for the determination of phthalates (DBP, BBP, DEHP, relative standard deviation (%RSD) were from to . Wide ranges of linearity of DNOP, DINP and DIDP) in plastics was standard curves were obtained from mg/L to described and applied to 20 toys in Ho Chi Minh city, Vietnam. Phthalates in the sample were 100 mg/L for DBP, BBP, DEHP and DNOP and from 25 mg/L to 1000 mg/L for DINP and DIDP extracted in a mixture of acetone and hexane and analyzed by GC-FID. Limits of detection (LOD) with R2 > . The studied method was a reliable, rapid, easy and cheap method and and limits of quantification (LOQ) of the analysis method for DBP, BBP, DEHP và DNOP in the permitted to determine the restricted phthalates in plastic toys in compliance with European PVC plastic were from to and Regulation (No 1907/2006). The method was from to , respectively. Recoveries of DBP, BBP, DEHP và DNOP in applied to determine phthalates in 20 toys in HoChiMinh city, Vietnam. Phthalates were found PVC and PP at two spiked concentrations ( and ) ranged from to with the in almost soft PVC toys with high concentrations. Keywords: GC-FID, GC-MS, phthalates in toy, platiscizer 1. INTRODUCTION Phthalate or phthalate ester is a general term for esterified substances of phthalic acid and alcohol. Phthalate esters are added to plastics to make these materials more flexible and elastic. Phthalates have toxicity such as carcinogenesis, immunization failure or reproduction failure The high concentrations of phthalates in toys will harm children’s health. The REACH .
