Abstract
A descriptive study was conducted to determine the concentrations of lead and cadmium in
soil, surface water, underground water, leachate, and air samples from the sanitary landfill area of 5
provinces, middle southern of Thailand and to measure the concentrations of lead and cadmium by
using AAS. The potential health risk was presented by HQ. A results of this study shown the
concentrations of lead in soil, surface water, under-ground water, leachate, and air samples at
-
mg/kg, 0.012-0.049 mg/l, 0.002-0.005 mg/l, 37-73 mg/l Ēúą nd-0.015 mg/m
3
, respectively. The
concentrations of lead in soil, surface water, under-ground water, leachate, and air samples were
0.076-0.124 mg/kg,
-
mg/l, 2.012-7.050 mg/l and nd-0.009 mg/m
3
, respectively. However, the
underground water did not detected the concentration of lead and cadmium. HQ of less than one
indicated that the environmental medias under this investigation posed no hazard to human health.
