Abstract:
Mineral bottled water packed in three polymers viz., virgin polyethylene terephthalate (PET), recycled PET, and low-density polyethylene (LDPE) were investigated for the occurrence, migration, and health risk of phthalic acid esters (PAEs) at 25 °C, 35 °C, and 45 °C. The average concentration of six USEPA priority PAEs in refrigerated water samples was highest in recycled PET> LDPE > virgin PET. The highest leaching was seen at 45 °C after 2 days for LDPE water packets with ∑6PAEs amounting to 64,300 ng/L. Similarly, for recycled PET, the highest migration was seen at 45 °C after seven days (3,800 µg/L). Bis 2-ethyl hexyl phthalate (DEHP) and di-n-butyl phthalate (DnBP) were the predominant plasticizers from PET bottles and LDPE water packets, respectively. Predicted concentration after three weeks based on best fit obtained through the polynomial model for PET bottles was seen higher than the recommended limit suggested by USEPA (6 µg/L) and WHO (8 µg/L).

Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...
Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
