| Outline of Final Research Achievements |
In semi-arid region, Asia, the livestock population has rapidly increased in recent years. Excessive grazing due to large numbers of livestock cause severe degradation of natural grassland. Furthermore, the vegetation cover of grassland has been reduced by extensive draughts caused by recent climatic changes in continental 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 carcinogen substances were contained in Hustai National Park (HNP) - Tuur river basin and surrounding soil. It can be considerable that cansinogen substances from urban area sause contaminations suburban area. For human health, wildlife, and the environmental resource protection, it is necessary to rethink conventional wisdom about effluent treatment.
