Water Quality Monitoring and Cadmium Contamination in the Sediments of Mae Tao Stream, Mae Sot District, Tak Province, Thailand

Abstract—Some lands and streams at Mae Sot District, Tak Province, Thailand are polluted by cadmium (Cd) which leach from the zinc mine. The objectives of present study were to evaluate physico-chemical parameters of Mae Tao Stream and Cd concentration in the sediments. The water and sediment samples were collected from the upstream and downstream of Mae Tao Stream from April 2011 to February 2012. The downstream sites are affected by the water from the zinc mine. Physico-chemical parameters such as Temperature, Water Velocity, pH, Electrical Conductivity, Total Dissolved Solid, Dissolved Oxygen, Nutrients (Nitrate, Ammonium and Orthophosphate), Suspended Solids, Alkalinity and Total Hardness were measured. Judged from the parameters, Mae Tao Stream was classified to Type III of the Surface Water Quality Standard of Thailand for agriculture at all sampling sites. Cd concentrations in the sediments were measured in the range of 0.84-7.86 mg kg-1. In the sediments of polluted sites, Cd concentrations exceeded the European maximum permissible level of 3.0 mg kg-1 for Agricultural Soil. It is important to continue to monitor the physico-chemical parameters and the cadmium concentrations in the sediments, and the bio-assessment should be begun around the stream.
