title: [Investigation of the water quality of Yalu Zangbo Jiang and the well-water of towns along it].
abstract: This article reports for the first time results of investigation on the water quality of the Yalu Zangbo Jiang and the wells-water of towns along it. It analysed such items of the water quality as pH, temperature, turbidity, total hardness, chloride, sulphate, nitrogen nitrate, fluoride, iron, manganese, zinc, copper, cadmium, lead and arsenic. The data indicated clearly that the turbidity and iron content of the river water and some of the wells were higher, but total hardness and fluoride content were lower, while other items analysed all conformed to the country's hygienic standard. Generally speaking, the hygienic standard of the water quality of the Yalu Zangbo Jiang, and the wells' water of towns along it is fairly good.
