Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] see figure 1 In the embodiment of the present invention, a method for analyzing the concentration of heavy metals in sediments from agricultural ditches to rivers includes the following steps:

[0030] (1) Sample collection

[0031] like figure 1 As shown, the samples of heavy metal content in agricultural ditch to river sediments were collected from the Changgou area, the river area, and the diffusion area, respectively. Th...

Abstract

The invention discloses a method for analyzing the heavy metal concentration of sediments from an agricultural ditch to a river, which comprises the following steps: setting a starting point and a plurality of sampling points, measuring the heavy metal concentration of the sediments at the sampling points, and recording the distance from the sampling points to the starting point to obtain total sample data; performing difference analysis on the overall sample data; analyzing the relationship between the heavy metal concentration and the distance by using a regression analysis method to obtain a linear regression equation; according to a linear regression equation, the heavy metal concentration changes along with the distance. By measuring and analyzing the heavy metal concentration of the sediments at different sampling points, the correlation between the concentration and the distance and the significance of the difference between different areas are found out, so that the change trend of the heavy metal concentration in the sediments from the agricultural ditch to the river is predicted.

Description

technical field [0001] The invention relates to the technical field of agricultural pollution prevention and control, in particular to a method for analyzing the concentration of heavy metals in sediments from agricultural ditches to rivers. Background technique [0002] Heavy metal pollution in agricultural ditch sediments will bring harm to surrounding plants, animals and microorganisms, and through the action of the food chain, after people eat livestock and poultry products raised with agricultural products near the pollution source as feed, it will bring harm and potential harm to human health. Heavy metals refer to a group of metal elements with an atomic density greater than 5 grams per cubic centimeter, about 40 species, mainly including cadmium (Cd), chromium (Cr), cobalt (Co), lead (Pb), copper (Cu), zinc (Zn), nickel (Ni), etc. It should be noted that elements such as selenium and aluminum, which have an atomic density of less than 5 grams per cubic centimeter, m...
