In semi-arid region, Northeast Asia, the livestock population has rapidly increased in recent years. Excessive grazing due to large numbers of livestock causes severe degradation of natural grassland. Furthermore, the vegetation cover of grassland has been reduced by extensive droughts caused by recent climatic changes in continental East Asia. These changes are likely to result in severe soil degradation and the release of large quantities of soil dust into the atmosphere.This study clarified that estrogen-like substances were contained in Hustai National Park(HNP)-tur river water and surrounding soil. It can be considerable that estrogen-like substances from urban area cause contaminations suburb area.For human health, wildlife (Takhi), and the environmental resource protection (grassland), it is necessary to rethink conventional wisdom about effluent treatment.In so far as Takhi protection in HNP, we should keep them away from Tur river.

在半干旱地区，东北亚地区的牲畜种群近年来增长迅速。大量畜牧业的过度放牧，导致天然草地严重退化。此外，由于东亚大陆最近的气候变化造成的大范围干旱，草原的植被覆盖率已经减少。这些变化可能导致严重的土壤退化和大量的土壤粉尘释放到大气中。本研究澄清了胡斯泰国家公园(HNP)-Turn河水和周围土壤中含有雌激素样物质。城市地区的雌激素样物质对郊区造成污染是相当可观的。为了人类健康、野生动物(Takhi)和环境资源保护(草原)，有必要重新思考关于污水处理的传统观念。就HNP的Takhi保护而言，我们应该让他们远离图尔河。
