Consider the following statements regarding impacts of plastic on mari...
• Both statements are correct
Impact of Plastic on Marine Ecosystem
• Plastics contaminate the marine environment; the increased use of plastics has lead to negative environmental impacts.
• Plastics pollution can interfere with the plankton species (phytoplankton – primary producer zooplankton primary consumers) and that form the foundation of the food web, and other organisms adversely affecting the delicate balance in the marine ecosystem.
Plastics as a Waste Material- in Marine Environment
• Plastic waste is well known to result primarily from fishing-related activities, and from non-point source influx from beaches.
• There are two clear differences between the fate of plastics debris in the ocean environment as opposed to on land environments.
1. The rate of UV-induced photo-oxidative degradation of plastics floating or submerged at sea is very much slower than that exposed to the same solar radiation on land.
2. Unlike on land there is no easy means of retrieval, sorting and recycling of plastic waste that enters into the ocean environment.
• These two factors generally result in extended lifetimes for plastics at sea.
Impact of Micro-particles
• Challenging the Antarctic krill and other zooplankton with plastic beads that are about 20 microns or so in size has demonstrated that these micro-particulates are readily ingested by these organisms. They appear to ingest the particles unselectively, and the ingestion rates depend on the concentration of particles in the environment.
• Plastics are bio-inert and are not expected to be toxic to the animal in the conventional sense. While physical obstruction or indirect interference with physiology is always possible (as with sea birds showing satiation on ingesting plastics) the material will pass through the animal virtually unchanged.
• Plastics exposed to sea water tend to concentrate toxic and non-toxic organic compounds present in the sea water at low concentrations. These, including PCBs, DDT, and nonylphenols, have very high partition coefficients and are very efficiently concentrated in the plastic material.
• Plastic-related distress to over 250 species has been documented worldwide. The focus has very much been on larger species in surface waters or beaches, despite the fact that 99 percent of marine species live in the benthos. The impact of negatively buoyant plastic waste (such as nylon net fragments) on benthic species has remained virtually unaddressed.
