Assessment of Pesticides and Polycyclic Aromatic Hydrocarbons in Beef Jerky Meat From Nigeria and Their Dietary Concentration to Human

Abstract

The study reports the concentrations, daily intake levels and possible potential health risks of 33 pesticides and 16 polycyclic aromatic hydrocarbons (PAHs) in beef jerky meat samples collected from sellers in Ado-Ekiti, Nigeria. The PAHs concentration (µg/kg) ranged from 0.007 (indeno(1,2,3-cd)pyrene) to 0.516 (acenapthylene), while pesticides (µg/kg) ranged from 0.010(2,4,6-trichlorophenol) to 0.272 (oxamyl). The estimated daily intakes of the pesticides were within the acceptable daily intakes (EDI˂˂˂ADI). The hazard indices were significantly less than 1 (HI ˂˂ 1) with estimated range of 1.08 × 10 -7 (pyriproxyfen) to 1.81 × 10 -4 (aldrin). Non carcinogenic equivalent (mg/kg/day) intakes of PAHs from beef jerky consumption ranged from 0.000027 (pyrene) to 0.00421 (anthracene), while the carcinogenic equivalent concentration ranged from 0.000024 (chrysene) to 0.265 benzo(a)pyrene. The risk associated with beef jerky meat showed no potential non-carcinogenic and carcinogenic risk while mutagenic and carcinogenic risk revealed low potential health risk as compared to the guideline value (1.0 × 10 -6 ) for potential cancer risk.
