  Mercury emitted to the atmosphere may pollute different environmental compartments in term of dry and wet fall out deposit. This study aimed to investigate the Total mercury (THg) concentration in dry deposit, surface soil, rice grains and assess its potential risks. Sampling field survey conducted during one period of sample collection. Result shown that Thg concentration in dry deposit were ranged from 1.76-4.00 μg m-3 day-1, surface soil were ranged from 85.94-193.33 μg kg-1 dw in 0-5 cm depth and 120.64-226.59 μg kg-1 dw in 5-10 cm depth and brown rice were in the range of 99.1-181.5 μg kg-1 ww and white rive were in the range of 113.1-185.1 μg kg-1 ww, respectively. The elevated THg in dry deposit were in St. 4 and 5 had average values with 3.46 μg m-3 day-1) while in surface soil (0-5 and 5-10 cm) had averages of 161.64 and 177.89 μg kg-1 dw), respectively. Hence in conclusion, THg concentration in dry deposit and surface soil were due to results of ore amalgam processing that correspond to the elevated THg concentration in atmospheric dry deposition.
