This research were aimed to 1) investigate amount of green mustard distribution lanes from the farmers in Banjarangkan District to the retailers 2) to investigate kind of distribution lanes and post harvest handling at each distribution lanes of green mustard and 3) to investigate Pb and Cd content in green mustard which was distributed from the farmers at Banjarangkan District to the retailers. The study used a survey method with the application of CSAM in the form of questionnaire distributed to farmers, collectors, wholesalers, and retailers green mustard. Laboratory analysis using AAS to determine the levels of Pb and Cd in green mustard. There were four distribution lanes of green mustard from farmer at Banjarangkan District to Retailers, namely lane 1 (farmer ? retailer), lanes II (farmer ? collector ? retailer), lanes III (farmer ? collector ? wholesaler ? retailer) and lanes IV (farmer ? collector ? retailer).

Loss impact on retail level was on the display reached 12% (significant). The concentration of heavy metal Pb and Cd on lane I ranged of 0,4768–0,4966 mg/kg and 0,4718–0.4768 mg/kg; in the lane II ranged of 0,3675–0.4519 mg/kg and 0.4867–0.5562 mg/kg; in the lane III ranged of 0.3129–0.4023 mg/kg and 0.5016–0.5662 mg/kg; in the lane IV ranged of 0.3923–0.4370 mg/kg and 0.5066–0.5314 mg/kg.
