Example Embodiment
[0031] In order to verify the correlation between the micronucleus test of faba bean root tip and the degree of heavy metal complex pollution, we designed an experiment.
[0032] 1. Sample Collection
[0033] After on-the-spot investigation and research, and on the basis of comprehensive consideration of natural conditions such as landforms, soil types, soil uses, etc. in the study area, as well as various human factors, we formed a plan for setting up sampling points in Nanjing Industrial Zone. In April 2011, The sampling points are set in a radial shape from near to far, and at each sampling point, surface soil samples at a depth of 0-20 cm are collected. During the collection process of each sample, GPS was used for precise positioning, and the environmental conditions and geographical conditions near each sampling point were investigated. Remove plant residues, stones, etc. in the soil mixed sample, and place it in a cool, ventilated place to air dry naturally. See Table...
