Erials and Solutions two. Components and Procedures 2.1. Sample Collection and Chemical Analysis 2.1. Sample Collection and Chemical Analysis As shown in Figure 1, the analysis location is positioned in Tai Lake, Jiangsu Province. Soil As shown in Figure 1, the study area is located in Tai Lake, Jiangsu Province. Soil sampling was carried out near Tai Lake. There areare six soil types in this study region, insampling was carried out close to Tai Lake. There six soil forms in this study region, which includes Anthrosols, Ferralisols, Luvisols, Skeletol primitive soils, Dark Semi-hydromorphic cluding Anthrosols, Ferralisols, Luvisols, Skeletol primitive soils, Dark Semi-hydromorsoils, soils, Hydromorphic soil. soil. Most soil samples (783, 80.6 ) have been distributedin Anphic and and Hydromorphic Most soil samples (783, 80.six ) were distributed in Anthrosols, followed by Ferralisols (101, ten.4 ), Luvisols (23, two.3 ), Skeletol primitive soils throsols, followed by Ferralisols (101, ten.4 ), Luvisols (23, 2.3 ), Skeletol primitive soils (18, 1.8 ), Dark Semi-hydromorphic soils (7, 0.7 ), and Hydromorphic soils (0, 0 ). (18, 1.8 ), Dark Semi-hydromorphic soils (7, 0.7 ), and Hydromorphic soils (0, 0 ).Figure 1. Spatial distribution of measured samples and soil form in the study location. Figure 1. Spatial distribution of measured samples and soil sort within the study location.According to the grid layout, a total of 971 sampling points had been collected for the duration of In accordance with the grid layout, a total of 971 sampling points have been collected during 2010011, WZ8040 Technical Information included 854 farmland samples, 9898 dryland samples, andpaddy land samples, 2010011, integrated 854 farmland samples, dryland samples, and 11 11 paddy land samand correct longitude and latitude coordinates were recorded with GPS.

To most sampling points were were distributed around the farmland of the research ensure that thethat the modeling set as well as the validation set represented the statistical characterisensure modeling set as well as the validation set represented the statistical traits of your sample,sample, we used the random function to randomlyaextract a 2:1 scale in the tics in the we employed the random function to randomly extract two:1 scale from the 971 soil samples, making use of 649 because the modeling set along with the remaining 322 as the validation set. In the course of the sampling process, the soil sampling depth was 0 20 cm. To avoid the effects of soil which had been transferred from someplace else or disturbed by some humanLand 2021, ten,four ofactivities, at the same time as newly disturbed soil layers, five-point sampling approaches have been utilized to take away surface debris and gravel in the soil, retaining 1kg of YTX-465 MedChemExpress polyethylene self-capsuling soil sample for each and every collected sample. In this study, the contents of six heavy metals, Cd, Hg, As, Pb, Cu, and Zn, have been determined. Cd and Pb in soil had been determined by graphite furnace atomic absorption spectrometry (Optima 2100DV, Perkin Elmer, USA), Cu and Zn in soil have been determined by flame atomic absorption spectrometry (Optima 2100DV, Perkin Elmer, USA), Zn, Hg, and As in soil had been determined by atomic fluorescence spectrometry (Primus-II, Rigaku Corporation, Japan), and Cr in soil was also determined by inductively coupled plasma atomic emission spectrometry (Optima 2100DV, Perkin Elmer, USA). The course of action of measuring heavy metal conce.
