Heavy metals in dates (Phoenix dactylifera L.) collected from Medina and Dhaka City markets, and assessment of human health risk

Constantly eaten foods (such as fruits, vegetables, cereal, etc.) that contain excessive concentrations of heavy metals pose a major risk to human health and deplete the food supply. The amounts of heavy metals in different date varietiies were measured after they were collected from three wholesale markets in the major cities of Dhaka, Bangladesh, and Medina. In order to look at the health risks associated with heavy metal consumption after intake of dates, the Average Daily Intake (ADI), Hazard Quotient (HQ), and Hazard Index (HI) were also calculated. Copper (Cu), Cadmium (Cd), Chromium (Cr), Iron (Fe), Lead (Pb), Manganese (Mn), Nickel (Ni), and Zinc (Zn) levels were evaluated. Several analyses of date fruit exhibited levels of Pb and Cd in different date varieties that beyond the Maximum Permissible Limit (MPL). In the majority of the samples, ADI was below the upper authorized tolerated daily consumption. The likelihood of a health risk from the regular eating of the investigated date fruits is revealed by the hazardous indexes of samples taken from New Market and Badamtali that surpassed unit value as a result of excessive air pollution brought on by greater industrial and vehicle traffic. According to the study, the majority of the analyzed heavy metals were identified in date samples and those from later samples at levels that were less harmful than the maximum acceptable threshold (MAL). Some samples included higher levels of Pb and Cd. As a result, eating dates that contain more metal has a higher chance of harming your health. Additionally, it has been recommended that regular testing for heavy metals in date fruits may be useful in preventing health risks associated with eating fruits that are contaminated with heavy metals.
