Soil Heavy Metal Content Analyzer

Soil heavy metal pollution is becoming increasingly severe, leading to the accumulation of heavy metals such as cadmium, copper, arsenic, chromium, mercury, nickel, aluminum, fluorine, titanium, selenium, iron, zinc, manganese, and copper in the soil's topsoil layer. This has become one of the primary environmental issues facing us today.

Heavy metals in soil enter the food chain through accumulation in crops, posing a serious threat to human and animal health. The mining of non-ferrous metal ores, the discharge of industrial “three wastes” (wastewater, waste gas, and solid waste), the accumulation of heavy metal-containing waste, the use of wastewater for irrigation in agricultural production, and the improper use of agricultural chemicals can all lead to harmful heavy metal elements entering the soil directly or indirectly, resulting in severe exceedances of heavy metal content in soil, crops, fruits and vegetables, water quality, and aquatic products.

However, current heavy metal testing methods are slow, cumbersome, and require expensive equipment. In response to this situation, we have developed a rapid heavy metal testing method.

The high-precision soil heavy metal content analyzer can rapidly and simultaneously determine the levels of arsenic, lead, cadmium, chromium, mercury, nickel, aluminum, fluorine, titanium, selenium, iron, zinc, manganese, and copper in samples such as soil, fertilizers, crops, vegetables, fruits, water quality, and food.
