Identification of major acidic and basic species in rain water at Semenyih Dam water resources area / Nor Azura Mat Desa

A comprehensive study on the composition of rainwater was carried out from July 2007 to September 2007 at Semenyih Dam Water Resources Area. This area is a semi urban with no agricultural activities within 15 km range, no industrial activities within 20 km and located 15 km heavy traffic. All sample...
