ABSTRACT

Microplastics (MPs), which are defined as particles of plastic waste with a size smaller than 5 mm, are considered as emerging contaminants and attract global attention. On plants, MPs have detrimental effects such as interfering with nutrient absorption, slowing germination and roots development. Of all the stages of growth, seeding has an important role in the crop yields obtained. The examined the impact of three polymer MPs (1 % w w–1) on paddy seeding and control as a comparison with four repetitions by using soil culture experiment for 20 d. Plant height, leaf length, root length, fresh weight, chlorophyll, and MPs identification in the roots were observed in this study. The data gained were run through ANOVA, followed by randomized complete block design (RCBD). Overall, three types of MPs polymers affect the growth of rice plants. HDPE (High Density Polyethylene) showed no effect on root elongation compared to LDPE (Low Density Polyethylene) and PVC (Polyvinyl Chloride) although all MPs still reduced plant growth (27 %  HDPE, 36 % PVC and 20 % LDPE), fresh weight (20 % HDPE, 33 % PVC, and 25 % LDPE) and total chlorophyll (72.5 % HDPE, 33.3 % PVC, and 19.8 % LDPE). HDPE types tend to require a longer time to fragment into smaller plastic sizes compared than other microplastics, soe not accumulated thoroughly in the roots. Further research should be carried out by treating organic matter and earthworms to bioremediate MPs.
