Assessment of heavy metals contamination was carried out in agricultural soil in Wanasari, Brebes Regency, Central Java Province. The study purposed to assess the level of metal contamination using statistical analysis, contamination factor (CF), geo-accumulation index (I-geo), and load pollution index (PLI). In this research, a total of 18 topsoil samples were taken and analyzed for the several metal concentrations are Pb, Cd, Cr, Co, and Ni. The concentration of heavy metals in soil samples was in the order of Cr > Ni > Pb > Co > Cd. The I-geo values of Pb, Co, Ni, and Cr indicated uncontaminated soils, while I-geo values for Cd showed level contamination in soil was uncontaminated to moderately contaminated. The values of pollution load index (PLI) indicated that these observed samples in agricultural soils for shallot in Wanasari, Brebes Regency were uncontaminated.
