Heavy metal analysis

Heavy metals are biochemically active elements that are part of the organic matter cycle and primarily affect living organisms. Heavy metals that can occur in garden or agricultural soil include lead, copper, zinc, cadmium and nickel. Some heavy metals, such as copper and chromium, are vital for humans and plants in trace amounts. However, in higher concentrations they usually have a toxic effect.

Heavy metals also have a negative effect in the soil if the limit values are exceeded, because they bind to certain protein groups and block the enzyme synthesis by soil microorganisms, plants and animals. Since increased heavy metal uptake sometimes becomes negatively noticeable only years later, an appropriate soil analysis is essential for the evaluation of the soil quality. Soil testing is important for assessing soil contamination and predicting the intensity of pollutant accumulation in soils.
