This can cause serious harm to the species that drink the water.Landfill areas contain many different types of plastics.Depending on their chemical composition, plastics and resins have varying properties related to contaminant absorption and adsorption.
Macrodebris are often found in ocean waters, and can have a serious impact on the native organisms. Even after they have been abandoned, they continue to trap marine organisms and other plastic debris.
Eventually, these abandoned nets become too difficult to remove from the water because they become too heavy, having grown in weight up to 6 tons.
Mega- and micro plastics have accumulated in highest densities in the Northern Hemisphere, concentrated around urban centers and water fronts.
Plastic can be found off the coast of some islands because of currents carrying the debris.
Plastics are more likely to be found in enclosed regions such as the Caribbean.
Plastic pollution, more so in the forms of macro- and mega-plastics, potentially serves as a means of distribution of organisms to remote coasts that are not their native environments.Their abundance has been found to transport persistent organic pollutants, also known as POPs.These pollutants have been linked to an increased distribution of algae associated with red tides.It is estimated that a foam plastic cup will take 50 years, a plastic beverage holder will take 400 years, disposable diaper will take 450 years, and fishing line will take 600 years to degrade.It is estimated that global production of plastics is approximately 225 mt/yr.Both mega- and macro-plastics are found in packaging, footwear, and other domestic items that have been washed off of ships or discarded in landfills.
