PFAS, bisphenol, and paraben in Malaysian food and estimated dietary intake

Endocrine disrupting chemicals (EDCs) such as per- and polyfluoroalkyl substances (PFAS), bisphenols, and parabens are used in food packaging or as preservatives and their unintended consumption has been associated with cancer and other diseases. Food EDCs data are scarce in Malaysia. Thus, liquid chromatography mass tandem spectrometry (LC-MS/MS) was utilised to analyse 18 EDCs from different food categories. Bisphenol was the most abundant EDC found, followed by PFAS and paraben. Bisphenol levels in canned foods, dairy products, canned drinks, fruits, and vegetables ranged from 1.16 to 183 ng/g. PFAS was found in almost every food category, with canned foods having the highest concentrations (0.18-34.5 ng/g). Only canned foods, fruits, and vegetables contained parabens, with mean concentrations ranging from 0.27 to 26.7 ng/g. PFOS, PFBA, PFHQA and bisphenol A all had hazard quotients (HQ) above 1, indicating that they can pose a risk to human health.
