From: Effect of co-presence of cadmium or procymidone with microplastic films in soil on lettuce growth
Effect of microplastics in the control soils (i.e., uncontaminated soil) on the a length of lettuce leaves per lettuce seedling during the 25 d-growth period, b number of lettuce leaves per lettuce seedling during the 25 d-growth period, c final length of lettuce seedling after 25 d, and d final number of lettuce leaves after 25 d. Control: soil without microplastic contamination, PVC control soil with polyvinyl chloride (PVC) contamination, LDPE control soil with low-density polyethylene (LDPE) contamination
