Phytoremediation is an alternative to traditional chemical and ways of treating polluted soils. The current study was carried out to investigate the phytoremediation of soil contaminated with nickel (Ni) by Lepidium sativum. Soil samples from 0 to 10 cm depth were collected. Lepidium sativum was transplanted in pots containing 5 kg of the collected soils. Central composite design and response surface methodology were employed in order to illustrate the nature of the response surface in the experimental design and explain the optimal conditions of the independent variables. Different concentrations for Ni (1 to 20 mg kg-1) and times for collecting samples (10 to 40 days) were used. The results showed the amount of Ni removed was ranged from 8.62 mg kg-1 (Ni concentration of 20 mg kg-1 and time for taking samples of 10 days) to 7.066 mg kg-1 (Ni concentration of 10.50 mg kg-1 and time for taking samples of 40days). Additionally, the findings explained that the Lepidium sativum is an effective accumulator plant for phytoremediation of Ni polluted soils. Optimum conditions for nickel concentration and time for taking samples were 19.66 mg kg-1 and 39.28 days, respectively. For the optimum condition, the amount of Ni removed was 10.8095 mg kg-1.

This study was carried out to optimize formulation for Heracleum Lasiopetalum (golpar) extract nanoencapsulation by response surface methodology (RSM). The primary emulsion was fabricated by (5-10 %) golpar extract (GE), (40-35 %) emulsifier span 80 (EM), and (50-60 %) sunflower oil (SO). The coating materials of nanoencapsulation were the composition of Lepidium sativum seed gum (LSG) and whey protein concentrate (WPC) at different ratios (1:0, 1:1, and 0:1). The yield of nanoencapsulation of golpar extract, particle size, and zeta potential was investigated as responses of RSM. The optimal formulation for nanoencapsulation of golpar extract were SO: 50.46%, GE 9.52%, and EM: 36.30% in LSG, SO: 57.07%, GE: 7.12%, and EM: 30.85% in LSG:WPC, and SO: 54.98%, GE: 9.05%, and EM: 39.87% in WPC coating. In conclusion, the nanoencapsulation of golpar extract prepared with the optimized formulation by RSM ensures the gradual release and sedimentation during storage with nanometric size and high yield of encapsulation. The nanocapsules of golpar extract can be used as a natural antioxidant in food systems.
