Effect of pollution with crude oil and used motor oils on the concentration of protein and carbohydrates in safflower and flax plants

Abstract

This study was conducted to clarify the effect of soil pollution with crude oil, car, and generator used oil on the concentration of protein and carbohydrates in Carthamus tinctorius and Linum usitatissimum plants as the soil was treated with crude oil and used oils for car engines and generators at three concentration for each , which are(1, 2, 3)%. The results showed that the treatment of safflower and flax plants with used motor oil and crude oil at concentrations (3)%, respectively, led to a significant decrease in protein concentration in the shoots of the two plants, reaching (0.503, 0.175) mg/g dry weight, respectively. Then, treating the two plants with crude oil at the concentration (3)% led to a significant decrease in the carbohydrate concentration in the shoots of the two plants, reaching (1.110) and (1.100) mg/g dry weight, respectively, compared to the comparison treatment, which amounted to (3.805, 3.860) mg/g. Dry weight, while we note that crude oil was significantly more effective, as it led to a decrease in the protein concentration in the two plants, reaching (0.565) mg/g dry weight, and no significant differences were observed between the effect of oil and oils for engines of generators and cars.
