Evaluation of Heavy Metals of Lead, Nickel, Cadmium, Vanadium and Some Chemical Parameters in Surface Soils of the City of Khorramabad

This study was conducted in 2017 with the aim of determining distribution heavy metals lead, nickel, cadmium, vanadium and parameters acidity, electrical conductivity organic matter surface soils city Khorramabad. Sampling performed monthly from 12 stations repeated 3 times autumn. The highest amount cadmium observed soil samples industrial areas two sampling periods October December to be 7 ppm. A comparison mean measured values elements showed that average amounts are lowest residential areas. 8th 11th at 2 lead 6th station, a bustling area, 22 nickel higher than other In during period October, its determined 58 mg/kg. recorded staion9 52 Lead has significant correlation acidity. is 0.01% for acidity variables 0.03% nickel. Nickel level 0.01%. results indicate Khorramabad not contaminated studied metals. general, both human natural factors always involved concentration
