The presence of heavy metals in food is a global problem. The paper aimed to examine the content of cadmium (Cd) and lead
(Pb) in instant coffee and instant coffee substitutes. The safety of consumption of the beverages by adult Poles was estimated based on the following parameters: tolerable weekly intake (TWI) %, benchmark dose lower confidence limit (BMDL) %, chronic daily intake (CDI), target hazard quotient (THQ) and hazard index (HI), for three beverage consumption patterns— one, two or three servings a day. Forty-nine samples of coffee, instant coffee drinks and coffee substitutes were analysed. The content of cadmium and lead was determined by ICP (inductively coupled plasma) analysis. The maximum level of Cd in the analysed beverages was 3.2 μg, and that of Pb was 82.6 μg per 1 kg. The tolerable level of intake of Cd (TWI) and Pb (BMDL) with the analysed beverages did not exceed 2.5%. The value of CDI, THQ and HI was not higher than 1, which
means that the risk of diseases related to chronic exposure to Cd and Pb consumed with coffee should be evaluated as very
low. However, special note should be taken of Pb, as the level of this metal was higher than that of Cd, and for beverages
with a higher weight per serving (e.g. Cappuccino), the intake of Pb can exceed consumer-safe levels if they are consumed
on a regular basis. Therefore, it should be considered whether it is advisable for flavoured multi-ingredient instant coffee
drinks to be consumed from time to time only, and natural coffee with optional milk and/or sugar be the choice of regular
coffee drinkers.
