Embodiment Construction

[0042] The present invention will be described in further detail below through specific examples, and the following examples are only descriptive, not limiting, and cannot limit the protection scope of the present invention with this.

[0043] Hunan Province is one of the provinces with the most serious heavy metal pollution in my country. Among the 30 key prevention and control areas involved in the "National Competitive Review of Heavy Metal Pollution Prevention and Control Key Areas", Hunan alone has 11, mainly distributed in non-ferrous metal mining areas and the Xiangjiang River Basin. As the core area of ​​economic development and urbanization in Hunan Province, the Changzhou-Zhuzhou-Xiangtan area has become a major area heavily polluted by man-made pollution due to its industrial structure dominated by traditional manufacturing industries such as non-ferrous metallurgy, machinery manufacturing, and chemical raw materials. Heavy metals such as Cd, Pb, Zn and Cr accumulated...

Abstract

The invention relates to an analysis method for heavy metal accumulation and morphological characteristic analysis of a main heavy metal pollution source of rice field profile soil. The method comprises the following steps: (1) sample collection; (2) sample pretreatment; (3) sample determination and analysis; (4) a heavy metal pollution evaluation method; (5) data statistical analysis. Accumulatedcharacteristics and form distribution rules of six heavy metal elements (Cd, Pb, Cu, Zn, Cr and Ni) in profile soil of rice fields near a normal fertilization (organic fertilizers such as pig manure)area, a pig farm biogas slurry irrigation area, a lead-zinc mining area, an industrial area and the like without obvious pollution sources in a long plant pool area in Hunan are taken as research objects, the analysis method effectively overcomes the defects in the prior art, evaluates the pollution risk of the rice field soil in the region by adopting a single pollution index and a comprehensivepollution index, and analyzes a main possible pollution source in the region with the unknown pollution source by utilizing the morphological distribution characteristics of the soil heavy metals inthe region with the known pollution source.

Description

technical field [0001] The invention belongs to the field of ecology and environmental protection, and relates to a soil heavy metal source analysis technology, in particular to an analysis method for analyzing heavy metal accumulation and morphological characteristics of soil heavy metals in paddy field sections. Background technique [0002] Under natural tillage, leaching, etc., the heavy metals accumulated in the soil will migrate horizontally and vertically, making them present different accumulation characteristics and morphological distributions in the soil profile. Studies have shown that the accumulation and form distribution characteristics of heavy metals in the profile soil are affected by pollution sources. For example, the surface layer of heavy metals such as Cd, Pb, and Cu in the rice field soil of the Jiangxi tungsten mining area is obviously enriched, while the soil profile near the new mine entrance of the Fenghuang lead-zinc mining area There is an obviou...
