Corresponding To manage waste agricultural and food industries biomass and to convert it into a material resource this research was carried out. The current study deals with the utilization of Apple pomace   as agricultural and food waste materials as bio-sorbents for removal of toxic heavy metal ions: Nickel, Cadmium and Lead from studied Oryza Sativa rice cultivated in Babol paddies’ rice in Mazandaran province in the north of Iran. Fresh experimental Apple Pomace samples were collected from several main factories (such as Sanich) in Tehran county and Saveh city, Iran. Nickel, Lead and Cadmium concentrations in treated rice by Apple Pomace and conventional rice products were determined by wet digestion method and samples were analyzed according to standardized international protocols by wet digestion method and Flame Emission Spectrophotometer. The content of Ni, Pb, and Cd in the samples were analyzed by ANOVA, followed by Student’s t-test (P<0.0). Our data revealed that mean  Pb concentration in studied paddies which treated by AP significantely decreased ( p ≤ 0.005 ) . The mean level of lead ( mg/kg DW) for all studied rice samples in studied paddies without treatment was 2.7171 ± 0.011( mg/kg DW± SE) but for studied smples from  paddies by AP which treated 10 days before the transplanting rice stems decreased to 0.0101 ± 0.001(mg/kg DW± SE). https://www.biotech-asia.org/vol13no4/remediation-of-contaminated-rice-farmlands-soil-and-oryza-sativa-rice-product-by-apple-pomace-as-adsorbent/ Apple Pomace; Remediation Soil; Oryza Sativa Rice; Adsorbent; Rice Paddy
