Microplastics (MPs) have become a global environmental concern because of their ubiquitous presence. Under investigation, over 80% of the plastics are flowing into the oceans. Definitionally, MPs consist of either deliberately manufactured commercial micro-particles, including scrubbers, abrasives, and precursor pellets (primary sources), or as fragments and fibres derived from the deterioration of larger products (secondary sources). For their characteristics of weeny and migrant, MPs can act as vectors for environmental contaminants. Once they are exposed to organic pollutants, it would absorb onto the surface of POPs and accelerate their mobility. Consequently, the microparticles laden with high levels of POPs can be ingested by marine biota. Therefore, it is highly likely that pollutants will accumulate in marine biota, which may bring more serious ecological crisis on aquatic plants, animals and microorganisms. |
