AB  - Microplastics had been collected at two sites namely Trou d'eau Douce (TD) and La 
      Cambuse (LC) public beaches, lying in the east coast and south-east coast of 
      Mauritius, respectively, over 6 months from September 2019 to February 2020. The 
      sizes of the latter varied from 180 microm to 4 mm. A higher amount of microplastics 
      collected/6-kg sand sample was recorded at LC. Two-way ANOVA revealed that (1) 
      there was a considerable gap in the variability regarding quantity and size 
      distribution of microplastics on the two beaches. The post-hoc analysis showed 
      that the majority of the microplastics at LC were > 1.40 mm, whereas the smaller 
      plastic fragments < 1.40 mm were more dominant at TD. (2) There was a significant 
      interaction between location and event (p value = 0.025). The post-hoc analysis 
      showed that the torrential rain hitting the island prior to sampling week 7 had 
      decreased the microplastic counts at both TD and LC, but not significantly. 
      Interestingly, the two hurricanes, prior to weeks 8 and 9, had appreciably 
      reduced the microplastic counts at TD and, on the other hand, there was an 
      increase in the amount of microplastics at LC, but not to a significant effect. 
      The chemical nature (qualitative analysis) of microplastics was determined by 
      density flotation and FTIR spectroscopy. Microplastics at TD were exclusively 
      high-density polyethylene (HDPE) in origin, whereas, at LC, microplastics were 
      both HDPE and polypropylene (PP) in origin.
