The presence of heavy metals in soil has become a significant global environmental issue due to their harmful impacts on plants, animals, and human health. Metals like lead (Pb), cadmium(Cd),mercury(Hg),chromium(Cr),arsen ic(As),iron(Fe),zinc(Zn),Manganese(Mn),Nickel (Ni) etc. find their way into the soil through activities such as industrial operations, mining, poor waste management, the application of chemical fertilizers, and sewage disposal. In contrast to organic pollutants, heavy metals are not easily broken down and tend to accumulate in the soil, causing long-lasting ecological harm. This contamination negatively influences soil fertility, microbial functions, and food safety, as crops can absorb these metals and introduce them into the food chain. Therefore, measuring heavy metal levels in soil is crucial for assessing. Some elements can enter water in the form of oxides ,chloride,carbonates etc. and affect aquatic ecosystem.When these water used as a irrigation purpose then soil becomes contaiminited. The environmental hazards and formulating remediation methods. In the present method 1-(2-pyridylazo)-2 naphtal(PAN) is used as a chromogenic reagent for the trace determination of some heavy metals in the soil samples.
