Description

technical field [0001] The invention relates to the technical field of soil sample collection equipment, in particular to a multifunctional sampling device used for soil and groundwater sample collection. Background technique [0002] The pollutants produced by human activities enter the soil and accumulate to a certain extent, causing the deterioration of soil quality, and then causing some indicators in crops to exceed the national standard, which is called soil pollution. There are various ways for pollutants to enter the soil. The pollutants contained in the exhaust gas, especially the particulate matter, settle to the ground under the action of gravity and enter the soil. The wastewater carries a large amount of pollutants into the soil, and the pollutants in the solid waste directly enter the soil or Its exudate enters the soil. The most important one is soil pollution caused by sewage irrigation. Extensive use of pesticides and chemical fertilizers has resulted in a...
