Consider the following statements regarding microplastic pollution and filtration mechanisms: I. Microplastics are defined as plastic particles smaller than 5 mm and are recognized as emerging pollutants in aquatic ecosystems. II. Domestic washing machines are a major source of secondary microplastics released into the environment via synthetic clothing fibers. III. Filter-feeding mechanisms in aquatic organisms rely entirely on electrostatic attraction to trap suspended microparticles. IV. Biomimicry in environmental technologies involves engineering engineering solutions inspired by biological structures. How many of the above statements are correct?
