Abstract
Description
Technical Field
[0001] The present invention relates to the field of soil pollution source analysis and scientific research technology, in particular to an atmospheric deposition collection method.
[0002] Device and method of use thereof. Background Art
[0003] Cadmium in atmospheric wet deposition mainly exists in the form of small molecule colloidal state (<3kDa) and ionic state (<0.45μm), accounting for more than 82% and 90% respectively; exchangeable and carbonate-bound cadmium in atmospheric dry deposition accounts for more than 25%, and in the coastal areas of East Asia, this form of cadmium accounts for more than 70%, and this part of cadmium has strong migration, bioaccumulation and toxicological effects. Highly active cadmium enters the soil through atmospheric deposition and is more likely to be enriched in the surface layer of soil aggregates. The original cadmium in the soil (including: parent rock matrix, anthropogenic activities, and previously deposited atmospheric cadmium) is mainly enriched inside soil aggregates, and the proportion of exchangeable cadmium enriched in soil surface aggregates is significantly higher than that in the soil aggregates, indicating that atmospheric cadmium is mainly combined with soil aggregates in the form of highly mobile and biologically effective states.
