The research investigated the migration potentiality of heavy metals (Pb, Cr, Cu, and Cd) from plastic cups into different food products at different time intervals. The study reported that the migration of heavy metals found to be highest in all samples at 10 minutes contact time intervals. The migrated concentrations of the selected heavy metals are in the order: Cu>Cr>Pb>Cd. The concentration of Cr found to be highest in lassi sample at 10 minutes contact time (0.3971 ppm), for Cu the value was highest in tea sample at 10 minutes contact time (0.9987 ppm). Both the concentration of Pb and Cd were highest at 10 minutes contact time in lassi (0.4714 ppm) and carbonated beverage (0.0030 ppm) respectively. The non-carcinogenic and carcinogenic risk assessment for heavy metals found an increase in risk potential with increase in contact time. All the samples had HI values below 1, and ILCR values <1×10^-6, meaning the samples consumed at this short interval don’t possess any non-carcinogenic and carcinogenic risks. The variations in the concentration of different heavy metals at the same time were due to the temperature of the product. And the study reported that the migration of the heavy metal is higher in foods with higher temperatures. Further research can be conducted to identify the effect of temperature, and simultaneous temperature-time effect on the migration of the heavy metal from plastic cups to foodstuffs.
