This research seeks to measure the lead, cadmium, copper, nickel, chromium, and arsenic in the paddy fields in Nganjuk Regency, as well as how much influence these metals provide on the environment and where they are located. Topsoil samples totaling 105 were collected in pursuit of this goal. The AAS was utilized to ascertain the elemental composition of the soil samples. The numerous soil pollution and ecological risk indices, such as Igeo, PI, IPI, PLI, and PERI, were used to analyze the situation. Spline interpolation with ArcGIS 10.2 was used to study metal distribution. The metal content in Pb, Cd, Co, Ni, Cr, and As was 10.01, 0.77, 9.60, 5.46, 3.61, and 2.79 mg/kg, respectively. There were no anthropogenic factors in the PCA or the HCA results; all elements came from natural sources. All of these pollutants had pollution index values between 0.59 and 2.56 and 0.05 and 0.56 on the lower end of the scale. With an average of 1.10-6, the pollutant load index suggests that all samples are safe. The rice fields in the research region have an average PERI score of 91.48, indicating a low ecological risk.
