Plastic pollution , accumulation in the environment of synthetic plastic products to the point where they create problems for wildlife and their habitats as well as for human populations. In the invention of Bakelite brought about a revolution in materials by introducing truly synthetic plastic resins into world commerce. By the end of the 20th century, however, plastics had been found to be persistent polluters of many environmental niches , from Mount Everest to the bottom of the sea. Whether being mistaken for food by animals , flooding low-lying areas by clogging drainage systems, or simply causing significant aesthetic blight , plastics have attracted increasing attention as a large-scale pollutant. Plastic is a polymeric material —that is, a material whose molecules are very large, often resembling long chains made up of a seemingly endless series of interconnected links. Today, however, the average consumer comes into daily contact with all kinds of plastic materials that have been developed specifically to defeat natural decay processes—materials derived mainly from petroleum that can be molded, cast, spun, or applied as a coating.

J Toxicol Risk Assess Since to , about 6. Human population increase and consistent demand for plastics and plastic products are responsible for continuous increase in the production of plastics, generation of plastic waste and its accompanied environmental pollution. We have reviewed in this paper, the most relevant literatures on the different types of plastics in production, the hazardous chemical constituents, prevailing disposal methods and the detrimental effects of these constituents to air, water, soil, organisms and human health viz-a-viz the different disposal methods. Papers that reported environmental and public health effects of plastic constituents but not plastics directly were also reviewed.
Plastic has become an important and integral part of society throughout the world due to its various applications, such as packaging, agriculture, automobile parts, electronic applications and medical devices. The plastic fabrication process can be modified to form various shapes, colors and specifications according to customer needs. Consequently, the amount of plastic waste is increasing due to the increase in plastic consumption because of the increasing population. Moreover, the problem of marine plastic debris is on the rise globally, including in Thailand, which results from the irresponsibility of mankind. Generally, plastic waste in Thailand can be generated from industrial processes and households.
Plastic pollution is the accumulation of plastic objects and particles e. Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.
In our full entry on Plastic Pollution we provide an in-depth overview of global plastic production, distribution, management, and impacts through data visualisations and explainers. There you should find most of the data and context needed to understand the problem of global plastics. How much plastic and waste do we produce?
