Plastics are widely used in our daily lives, and our lives cannot do without plastics. This paper introduces the concepts of relative irreplaceable coefficient and absolute irreplaceable coefficient, discusses the extent to which plastic waste can be reduced to an environmentally safe level, and reversely applies a health risk assessment model to describe the environmental safety level, and compares this safety level as a warning line for the amount of plastic waste.

Few other environmental problems have received as much public attention and criticism in recent years as plastic pollution. Accordingly, in recent years, a number of plastic policies have been adopted at the national and supranational level in the EU and worldwide. In the U.S., health risks were repeatedly raised in the decision-making process of these policies and scholars have pointed out the crucial role of these arguments for the adoption of plastic policies. Hence, this article uses a structuring qualitative content analysis to investigate the parliamentary debates of two recently adopted

Government-led legislation is a key strategy to reduce plastic pollution; however, societal perception can heavily influence government intervention for environmental issues. To understand the public acceptability of government action to reduce plastic pollution, we examine the perception of existing and upcoming legislative action on single-use plastics (SUPs) by means of a structured survey with additional semi-structured interviews. Our focus is on the four Atlantic provinces of Canada, which was the first region in Canada to implement provincial-wide legislation for plastic reduction at th

Plastic pollution is a planetary threat, affecting nearly every marine and freshwater ecosystem globally. In response, multilevel mitigation strategies are being adopted but with a lack of quantitative assessment of how such strategies reduce plastic emissions. We assessed the impact of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at different levels of effort to estimate plastic emissions to 2030 for 173 countries. We estimate that 19 to 23 million metric tons, or 11%, of plastic waste generated globally in 2016 entered aquatic ecos

A significant portion of the world’s plastic is not properly disposed of and, through various processes, is degraded into microscopic particles termed micro- and nanoplastics. Marine and terrestrial faunae, including humans, inevitably get in contact and may inhale and ingest these microscopic plastics which can deposit throughout the body, potentially altering cellular and molecular functions in the nervous and other systems. For instance, at the cellular level, studies in animal models have shown that plastic particles can cross the blood–brain barrier and interact with neurons, and thus aff

Background: Plastics, owing to their ease of use and affordability, have taken over every aspect of our modern world. It has become an essential aspect of our everyday lives, permeating every sector from food packaging to toys and electronics, to the degree that it is unimaginable to picture a world without it. Plastic takes around 15 to 1000 years to biodegrade. The consumption of plastic by individuals and the ineffective reuse or recycling of it has detrimental effects on the ecosysystem. Overusing plastic and neglecting disposal solutions for plastic over a long time led not only India but

Environment plastic accumulation has been attracting the attention of both political and scientific communities, who wish to reduce global pollution. Plastic items have been detected everywhere, from oceans to the air, raising concerns about the fate of plastics within organisms. Leaked plastics are ingested by animals, entering the food chain and eventually reaching humans. Although a lot of studies focused on the evaluation of plastic particles in the environment and living organisms have already been published, the behavior of plastic at the cellular level is still missing.

Abstract. Millimeter-sized plastics are numerically abundant and widespread across the world's ocean surface. These buoyant macroscopic particles can be mixed within the upper water column due to turbulent transport. Models indicate that the largest decrease in their concentration occurs within the first few meters of water, where subsurface observations are very scarce. By using a new type of multi-level trawl at 12 sites within the North Atlantic accumulation zone, we measured concentrations and physical properties of plastics from the air–seawater interface to a depth of 5 m, at 0.5 m inter

Plastic has found an irreplaceable part in human life. Human produces plastic wastes continually which results in pollution. In this paper GLCM (Gray Level Co-occurrence Matrix) technique is used for plastic segregation. Plastic segregation is necessary for recycling; hence they have to be segregated from other wastes. Manufacturing plastics from recycled plastic products uses only two-third of the energy used to make plastics from virgin materials. By the variation in intensity levels of reflected light from the plastic wastes it is segregated. This type of waste management gains attention in

Plastic is often used for various purposes in human life in very large quantities. From food packaging to automotive materials needs. Plastic is a very well-know material and is widely used as a material for making automotive components, besides metals, such as iron. The main problem with plastics is that they produce waste that doesn’t melt down naturally. It takes a very long time to produce all the plastic waste from the earth’s surface. Contolling the usse of plastic is becoming increasingly difficult, which will also cause air temperatures to be higher than usual, because the polymer has

This research presents a low-cost sensor for measuring liquid levels using plastic optical fibers (POF). The sensor reduces the scattering-based optical losses in the fiber, which increase linearly with the liquid height. A U-bent fiber probe and photodetector are used to detect the change in optical intensity. The U-bent probe serves as a test probe for measuring the liquid level. The voltage response difference of the photodetector provides liquid level measurement. This study demonstrates the sensor's responsiveness to liquid level fluctuations above 55 cm at varying temperatures. Sensitivi
