Plastic granules and their impact on the concentration of some mineral elements and conductivity in the soil

The current study was conducted in the plastic houses of the (University of Mosul - College of Education for Pure Sciences - Department of Biology), for the academic year 2024 for study the effect of soil pollution with granules of five types of plastic. The results showed that treating the soil with plastic granules of type C at a concentration of 50 and 100 gm/5 kg soil led to a significant decrease in the concentration of both nitrogen, phosphorus and calcium which reached (0.0049, 0.0019 ), (0.1248, 0.0906) and (0.008, 0.008) % respectively compared to their concentration in the comparison treatment, which recorded (0.0059, 0.1959 and 0.0200) %, respectively. When the soil was treated with PET plastic granules, the phosphorus concentration likewise significantly decreased, reaching (0.0632) % as opposed to (0.1959) % in the comparator treatment. Additionally, there was a notable drop in conductivity, which reached (0.714) %
