| Abstract: | By analyzing soil samples from Dalian Chemical Plant section, the paper studied As in various chemical states, such as water dissoloved staete, ammonium carbonate exchanged state, hydrochloric acid dissoloved state, sodium hydroxide dissoloved and residual state,and also determined the concentration of As3+, As5+ in these chemical states. As a result it extended to evaluate distribution characteristics and presented pollution situation of As in the section. The scientific basis for studying the migrating law and the prevention, as well as control of As in the environment were provided in this paper. |
