Janghang Korea Dataset

Soils were collected along the vicinity of a copper and gold smelter in Janghang town located in Seocheon County in South Chungcheong Province, South Korea. Soil samples were collected at a depth of 0-30 cm from paddy soils located at three different locations and were named based on their distances from the refinery center. Site 1 was located 260 m from the smelter and contained high levels of arsenic.Site 2 was located 240 m from the smelter and contained highest levels of arsenic because of its vicinity to the smelter. Site 3 consisted of rice paddy soil located 3500 m from the smelter and represented an area of low contamination.Soil sampling was done from three randomly selected areas within each site. Each area represented a replicate sample of a single site, and consisted of top and sub soils from three adjacent spots which were approximately 1 m away from each other.The data set contain the raw files obtained after pyrosequencing for each site.本数据集的土壤样本采集自韩国忠清南道舒川郡长项邑一处铜金冶炼厂周边区域。研究人员于三处不同点位的稻田中采集0~30 cm深度的土样，样本命名依据其距冶炼厂中心的距离确定。1号点位距冶炼厂260米，土壤砷含量较高；2号点位距冶炼厂240米，因紧邻冶炼厂，土壤砷含量为三处点位最高；3号点位距冶炼厂3500米，属于低污染区域，土壤类型为稻田土。每个点位均设置三个随机选取的采样区域作为重复样本，每个重复样本由彼此间距约1米的相邻三个采样点的表层与亚表层土壤构成。本数据集包含各点位经焦磷酸测序（pyrosequencing）后获得的原始文件。
