Map of Selenium Content in Soil in Japan

摘要: We present a new selenium (Se) map of Japan in more detail than our previous report (J. Health Sci., 42, 360-366). It contains 150 measured points, especially the northeast Japan. In sampling we did not find high Se levels and most measurements were generally at values below 1 mg/kg. Japan, there are two particularly measurements, Mt.Zao (10 mg/kg) Tateyama Murodo Jigokudani (148 mg/kg). These areas origin minor branch Abukuma River Jouganji River, respectively. also analyzed near major copper mines, Asio Besshi. detected content rocks both mines an average level soil from area mine. The Besshi was slightly higher that some pyrites ten mg/kg general soil. This study provides information about fundamental background to correlate with pollution if it occurs future
