It was found that zooplankton ingest microplastics beads (1.7−30.6 μm) and excrete fecal matter contaminated with microplastics. Along with ingestion, the microplastics stick to the appendages and exoskeleton of the zooplankton[20]. Zooplankton, among other marine organisms, consume microplastics because they emit similar infochemicals, notably dimethyl sulfide, as phytoplanktonand other organic materials [21][22]. Plastics such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP) produce dimethyl sulfide odors[21]. These types of plastics are commonly found in plastic bags, bleach, food storage containers, and bottle caps [23]. Furthermore, the microplastics plastics absorb chemical pollutants are transferred into the organism's tissues[24].
