- Thirteen food crops were analysed for aluminium, arsenic, cadmium and lead.
- Mean concentrations were used to calculate EDI, THQ and HI.
- TCR was calculated for arsenic for all food crops.
- The THQ and HI were <1 for all food crops; target cancer risk did not exceed 10â4.
- The food crops evaluated pose no undue risk to the consumer.
Thirteen Jamaican-grown food crops â ackee (Blighia sapida), banana (Musa acuminate), cabbage (Brassica oleracea), carrot (Daucus carota), cassava (Manihot esculenta), coco (Xanthosoma sagittifolium), dasheen (Colocasia esculenta), Irish potato (Solanum tuberosum), pumpkin (Cucurbita pepo), sweet pepper (Capsicum annuum), sweet potato (Ipomoea batatas), tomato (Solanum lycopersicum) and turnip (Brassica rapa) â were analysed for aluminium, arsenic, cadmium and lead by atomic absorption spectrophotometry and instrumental neutron activation analysis. The fresh weight mean concentrations in these food crops (4.25-93.12Â mg/kg for aluminium; 0.001-0.104Â mg/kg for arsenic; 0.015-0.420Â mg/kg for cadmium; 0.003-0.100Â mg/kg for lead) were used to calculate the estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and target cancer risk (TCR) for arsenic, associated with dietary exposure to these potentially toxic elements. Each food type had a THQ and HIÂ <Â 1 indicating no undue non-carcinogenic risk from exposure to a single or multiple potentially toxic elements from the same food. The TCR for arsenic in these foods were all below 1Â ÃÂ 10â4, the upper limit used for acceptable cancer risk. There is no significant health risk to the consumer associated with the consumption of these Jamaican-grown food crops.
