[Microbial characteristics and eco-health implication of mineral spring water in Wudalianchi, Northeast China].

Abstract

Mineral spring water is a top quality potable groundwater resource formed by long-term groundwater-rock interaction in aquifer. Mineral spring water is rich in minerals and trace elements which are beneficial for human health. Given the current serious water pollution and environment deterioration, it is of great significance to re-recognize the ecological and health effects of mineral water based on new scientific and technological achievement. The Wudalianchi scenic area in Heilongjiang Province has abundant mineral water and peloid resources, which supported the development of tourism and convalescence and have been used in medical and health care for more than 100 years. However, it is threatened by resource reduction, environmental pollution, and other problems. Here, we reviewed the formation process, distribution, hydro-biochemical characteristics and health effects of the Wudalianchi mineral springs, with particular focus on the advances of microbial studies in this area. We also proposed the future research prospective for the Wudalianchi mineral water. To better protect and utilize the Wudalianchi mineral water, it was recommended that a green eco-agriculture practice in reducing chemical fertilizers should be adapted in the surrounding farms of Wudalianchi. Along with the development of tourism and recuperation resources, it is necessary to establish a framework of pollution risk assessment and control, and strictly reduce potential emerging pollutants to eco-geological environment.
