Eighteen samples were collected and analyzed for As, Pb, and Cd, obtaining fifty-four results. The samples were washed with deionized water, air-dried and oven dries at 105°C for 48 hours and analyzed using Varian (USA) Atomic Absorption Spectrophotometer. The concentration of Pb, As, and Cd in the vegetable trend follows; Ebonyi south (ES) < Ebonyi central (EC) < Ebonyi north (EN); EN < ES < EC and ES < EC < EN respectively both for Pumpkin and Spinach vegetables. The Cd, As and Pb, content was below WHO/FAO, (2007) and EU, (2006) specific limits. The daily intake of metals, health risk index, and targeted health quotient were computed. The DIM of Pb, As and Cd were below their respective oral reference dose (RfD) of 0.004, 0.003, and 0.001mg/kg/day. Pb, As, and Cd HRI values for adults, teenagers, and children ar...

Resistivity meter and its accessories were used for data acquisition. The maximum current and potential electrode distance were 400 m and 20 m respectively. The field data were interpreted using Interpex software and three to five geo-electric layers encountered within the study area. The dominant curve type was H followed by K. From the result, geo-electric layers delineated were sandstone, clay, saturated sandstone, sandy shale, clayey shale, and shale with average apparent resistivity values of 2249.94 Ωm, 2.86 Ωm, 365.28 Ωm, 222.69 Ωm, 14.60 Ωm and 59.02 Ωm respectively. The top geoelectric layer was dominantly lateritic topsoil, with variation in degrees of compaction and having an average resistivity of 876.33 Ωm with depth and thickness generally less than 5 m. The calculated aqui...
