  Sequel to the high rate at which waterleaf (Talinum triangulare) is consumed in Southern Nigeria and the excellent phytoextraction and bioaccumulation potentials of the plant, an assessment of the safety status and potential human health risk of Lead (Pb), Calcium (Cd), Chromium (Cd) and Nickel (Ni) through consumption of waterleaf sold in major markets in Calabar, Nigeria was carried out between February and April, 2021. A total of 36 composite samples obtained from 180 waterleaf vendors was used for the study. Heavy metals concentrations were determined using Atomic Absorption Spectrophotometer (Shimadzu, Model AA-6800, Japan) after wet digestion. The concentration (Mg Kg-1) ranged from 0.26-0.59 for lead, 0.04-0.42 for cadmium, 0.35-1.02) and 1.35-4.32 for nickel. The mean metals content of edible tissues (leaves and tender stem) of waterleaf were found to be above FAO/WHO permissible limits and the EU maximum Levels for the metals in leafy vegetable except for chromium. The Estimated Daily Intake of the metals were above their respective Recommended Daily Intake and Upper Tolerable Daily Intake except for nickel. The average Target Hazard Quotients were greater than 1.00 except for chromium. The Hazard Index for the respective markets were greater than unity. The study concludes that Talinum triangulare purchased from the markets under study is not safe for human consumption as it poses significant toxicological risk with respect to lead, cadmium, and nickel and chromium intoxication. تفاصيل المقالة

  The assessment of some trace metals in soils around a municipal solid waste dumpsite in Gombe, Nigeria was conducted. Pollution indices and health risk parameters were determined in order to evaluate the ecological and health risk to the local environment. The soil samples were collected in dry and rainy seasons and analysed for (Fe, Cd, Pb, Mn, Zn, Cu, Cr, and Ni) using atomic absorption spectrometry. The content of trace metals (mg kg-1) at the dumpsite in dry season were: Pb (8.78), Zn (151.00), Ni (11.80), Cr (4.55), Cd (12.12) and Mn (92.05), while in rainy season, content of trace metals were Pb (8.80), Zn (148.00), Ni (11.63), Cr (4.20), Cd (10.03) and Mn (91.03). In both seasons, there was a significant increase (p<0.05) in levels of chromium, cadmium, zinc, nickel, lead, copper and iron in soil samples from the south (20 m) of the dumpsite and at the dumpsite compared to soil samples from the control site. Pollution indices studies showed that soil samples from south (20 m) of the dumpsite and at the dumpsite were highly polluted with cadmium, contributing 99% of the overall potential ecological risk. No potential health risk was detected, considering the fact that the hazard quotient and total hazard index of all the studied metals were less than one. However, children were found to be more vulnerable to heavy metal pollution than adults. تفاصيل المقالة
