Description

Technical Field

With the acceleration of industrialization and agricultural intensification, heavy metals, organic pollutants and complex pollution continue to accumulate in the soil, posing a serious threat to the ecological environment and human health. Traditional manual sampling methods have problems such as low efficiency and insufficient data representativeness, which makes it difficult to meet the needs of precise and standardized pollution investigations.
