The persistence, mobility and distribution patterns of phorate and terbufos in soil was not well explored. As a result, this study is designed to evaluate the residual uncertainty and leaching potential of horate and terbufos in packed soil columns. The leaching and distribution behavior of applied pesticides will indicate the soil-pesticide interaction and groundwater contamination through soil column leaching. In this study, a comparative soil column study is conducted following the OECD guidelines for leaching soil column test for exploring the distribution, and mobility of phorate and terbufos including their metabolic transformation into soil column. Briefly, the packed soil column (5 cm diameter, 50 cm height) were filled up to 30 cm, and oversaturated by capillary waters. After leaching test, the leachate and soil sections (each section for 10 cm depth) were analyzed for parent pesticides and transformed metabolites. According to GUS index, both phorate and terbufos considered immobile pesticide (no residue is detected in the leachate) with low to extremely low leachability. Besides, the major pesticides and metabolite concentration (˃90% recovered) was found in the upper layer soil (0-10 cm) followed by subsoils. Among the transformed metabolites, sulfone and sulfoxide were the predominant for both pesticides. The degradation of phorate and terbufos was controlled by soil moisture, organic matter, and soil texture, respectively. In summary, the persistence, distribution and metabolic transformation of phorate and terbufos is limited within the vadose zone soil (0-10 cm) and no parent pesticides were detected in leachate due to slow leaching potential and immobility.
