ABSTRACTRon phibun subdistrict is the old

mining area. It is possible that dust which

scattered from the rock and/or the mining

waste containing by arsenic. By setting

12 dust and rain water collecting stations

continuously for 1 year, dust and rain water

samples were collected and analysed for

arsenic concentration and study a relation

between arsenic level in dust and rain water.

The result of the study showed that the

average of arsenic level in dust in the

mining area is higher than the other sites.

On average, arsenic concentrat ions in

rainwater are lower than the drinking water

standard by WHO (10 mg/l) or in the range of

the uncontaminated area (0.55-12 mg/l) then

it can be believed that rain water is safe

water.
