Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.
