Plastic toys and child care articles as a source of children exposure to phthalates and other plasticisers in Saudi Arabia

Abstract

ABSTRACT Phthalates are chemical compounds added to plastic materials to provide flexibility. They are used in numerous consumer products including children’s toys and child care articles. Exposure to phthalates is linked to reproductive and developmental disorders in addition to endocrine disruption effects. This study is the first to investigate the presence and levels of phthalates and other plasticisers in children’s toys and child care articles sold in the Saudi market. Twenty-seven products were obtained from local marketplaces and analysed by GC-MS for the levels of the six regulated phthalates dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), di-(2-ethylhexl) phthalate (DEHP), di-n-octyl phthalate (DnOP), diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP). Other plasticisers and plastic additives were investigated qualitatively for potential risks. Overall, 19% of products tested were found to have one or more regulated phthalates exceeding the 0.1% w/w regulatory limit. All noncompliant items were made of polyvinyl chloride (PVC). In contrast, the 16 non-PVC items tested were compliant with regulations. Among the 11 PVC items tested, 45% were noncompliant. DEHP was detected in all 11 PVC products, with concentrations ranging from <LOQ-32.2% w/w, and with concentrations exceeding regulatory levels in 4 of 11 PVC products (36%). The other regulated phthalates detected in PVC products were DBP and DINP with amounts that ranged from <LOQ-0.275 and 0.218–14.2% w/w, respectively. Plasticisers other than the regulated ones were present in a number of products; including dioctyl isophthalate (DOIP), di(isononyl) cyclohexane-1,2-dicarboxylate (DINCH), methyl stearate, acetyl tributyl citrate (ATBC) and diisobutyl phthalate (DIBP). Inexpensive children’s toys were found to be less complying with the regulations of toys safety regarding phthalates content, which may pose more risk to children.
