Assessment of Human Health Hazard Due to Consumption of Trace Metal in Selected Sea Foods and Vegetables from Port Harcourt Markets, Rivers State, Nigeria.

vegetables, sea foods, EDI, TDI, WHO MPL, THQAbstract
Sea foods and vegetables are important in human diet and are consumed at very high rate and by majority of the population in Port Harcourt. Sea foods and vegetables contaminated with excess trace metals can cause health problems for humans and the ecosystem. Estimated the daily intake of selected metals were used to assess the health related risks of consuming sea foods and vegetables sold in two Port Harcourt major markets. Samples were collected randomly from the two markets and analyzed for Copper, Lead, Zinc, Cadmium and Chromium concentration (mg/kg) using Atomic absorption spectrometer, the results was used to estimate the daily intakes of the metals analysed and the Target Hazard Quotient (THQ) was determined. Some of the metals analysed showed levels higher than maximum permissible limits by regulatory agencies with estimated daily intake (EDI) exceeding the tolerable daily intake (TDI) stipulated by regulatory bodies. Recommendations are made for a coordinated approach to monitoring sources of these foods to abate any potential public health impact on the populations.
