Heavy Metal (Pb, Cd, Hg and As) Content of Some Pineapples Juice Produced in Informal Market in....

The aim of this study was to determine the extent of micropollutant contamination (mercury, lead, cadmium, and arsenic) in handcrafted pineapple juices sold in recovery bottles on the outskirts of Abidjan.

Samples were taken from street vendors in four different districts of Abidjan (Marcory, Treichville, Cocody and Koumassi).

Between December 2019 and June 2020, researchers at the Central Food Hygiene Laboratory and Agribusiness conducted research.

The 32 samples were analysed using an atomic absorption spectrophotometer.

Results: It appears that traces of a few metallic micropollutants were present in pineapple juices at varying levels, with some reaching the maximum lead values recommended in 75 percent of the juices tested. In terms of municipalities, arsenic concentrations in 100% of the juices obtained from vendors in the commune of Cocody surpass the maximum regulatory values. Overall, Daily Exposure Doses (DDE) are smaller than the Previsional Tolerable Dose (0.024 10-4 mg/kg bw of mercury, 0.345 10-4 mg/kg bw of lead, 0.001 10-3 mg/kg pc of cadmium, and 0.5 10-4 mg/kg bw of arsenic) (PTD).

Conclusion: Is it possible to remove the danger for the general public? Although the levels of metallic micropolluants present in pineapple juices are below the mercury and cadmium limits, they are high in lead and arsenic, raising the risk of adverse effects.
