Environmental hazards caused by plastic

To make the event "disposable-free", there was ban on the usage of disposable water bottles. Average levels of daily exposure are below the levels deemed to be unsafe, but more research needs to be done on the effects of low dose exposure on humans. These findings are in stark contrast with the European Union environmental risk assessment predicted environmental concentrations of 0.

When mass production of plastics began in the s, it quickly permeated into all facets of modern daily life [ 2 ].

Environmental hazard

Hence, more information is required on the biological mechanisms that may be affected by plastic additives and in particular, low-dose chronic exposures. A key conclusion from the paper by Talsness et al.

Methods to monitor the abundance of anthropogenic debris including plastics often vary considerably between countries and organizations, adding to difficulties in interpreting trends.

However, not all current uses of plastics are prudent and sustainable, as illustrated by widespread, unwanted human exposure to endocrine-disrupting bisphenol-A BPA and di- 2-ethylhexyl phthalate DEHPproblems arising from the large quantities of plastic being disposed of, and depletion of non-renewable petroleum resources as a result of ever increasing mass-production of plastic consumer articles.

The report was published this month in a theme issue of Philosophical Transactions of The Royal Society B, a scientific journal.

Phthalates and BPA are detectable in aquatic environments, in dust and, because of their volatility, in air Rudel et al. For BPA, there is an extensive published literature showing adverse effects of exposure at very low doses, based on administration during development and to adult experimental animals.

Government regulations have been implemented that ban some chemicals from being used in specific plastic products. The durability of the plastics is visible among the remains. Other plastics contain Bisphenol-A BPAwhich has been identified as a chemical that disrupts hormones.

Still, there is already evidence that chemicals associated plastics might harm wildlife. Thyroid hormone axis[ edit ] Bisphenol A affects gene expression related to the thyroid hormone axis, which affects biological functions such as metabolism and development.

Littering is a behavioural issue and some have suggested that it has increased in parallel with our use of disposable products and packaging. In some locations around Europe, it has been suggested that quantities on the seabed may exceed 10 items ha—1, and debris has even been reported more than a m below the ocean surface, including accounts of inverted plastic bags passing a deep-sea submersible like an assembly of ghosts Gregory Diverting solid waste Curbside plastic collection programs are driven in part by a wish to minimize municipal solid waste.

The potential for transport varies among contaminants, polymers and possibly also according to the state of environmental weathering of the debris. Land-based sources of ocean plastic pollution[ edit ] Estimates for the contribution of land-based plastic vary widely.

A single resin type might be mixed with many such additives, adding complexity to the chemical composition and possibly generating new classes of incompatible resins within the grossly simplified SPI resin code.

Environmental Health Science and Practice

Any single or combination of toxic chemical, biological, or physical agents in the environment, resulting from human activities or natural processes, that may impact the health of exposed subjects, including pollutants such as heavy metals, pesticides, biological contaminants, toxic waste, industrial and home chemicals.

Hence, the potential for plastics to transport and release chemicals to wildlife is an emerging area of concern. As the plastics recycling infrastructure develops and viable new plastics markets emerge, the Ecology Center will evaluate the collection of other plastics, based on operational, cost, and environmental concerns.

Plastic pollution

By affecting the thyroid hormone axis, BPA expoure can lead to hypothyroidism. Researching credible sources on this topic aided in answering the research question: Although evidence due to research so far has been sufficient for governmental agencies to take action, more is still being done to demonstrate conclusively that the negative health effects listed above and others are due to the compounds such as BPA and DEHP in plastic.

More recently, abundance at the sea surface in some regions and on some shorelines appears to be stabilizing, while in other areas such as the Pacific Gyre there are reports of considerable increases.

Please help improve this article by adding citations to reliable sources. Some of these compounds are added to plastics during manufacture while others adsorb to plastic debris from the environment.

An area of particular concern is Environmental hazards caused by plastic abundance of small plastic fragments or microplastics.

This article does not cite any sources. These seabirds choose red, pink, brown, and blue plastic pieces because of similarities to their natural food sources. In particular, unlike the case for experimental animal research on phthalates, there are now hundreds of experiments on laboratory animals using doses within the range of human exposures Vandenberg et al.

This is the goal of the new field of green chemistry, which is based on the premise that development of chemicals for use in commerce should involve an interaction between biologists and chemists. To help mitigate the potentially harmful chemicals in plastics, the authors recommend that more studies be conducted on the biological mechanisms that may be affected by plastic additives and in particular, low-dose chronic exposures.

Given our declining reserves of fossil fuels, and finite capacity for disposal of waste to landfill, this linear use of hydrocarbons, via packaging and other short-lived applications of plastic, is simply not sustainable. Prosthetics, engineered tissues, and microneedle patches for drug delivery are all possible with polymers [ 1011 ].Environmental and health hazards of chemicals in plastic polymers and products Delilah Lithner, Department of Plant and Environmental Sciences.

May 26,  · What are the Environment hazards due to plastics? What can we do as individual? Follow. 21 answers Plastic is a by product of oil and is not a bio degradable product. As a responsible citizen and individual, we can avert the hazards of using plastics, by educating the society around us and practicing the non-usage of all Status: Resolved.

The persistence of plastic debris and the associated environmental hazards are illustrated poignantly by Barnes et al. who describe debris that had originated from an aeroplane being ingested by an albatross some 60 years after the plane had crashed. Plastic pollution is a global problem.

The majority of plastic winds up in landfills where it remains indefinitely. No one exactly knows how long plastic takes to break down, but it is believed to take hundreds or even thousands of years.

Plastic pollution is the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat and humans.

[1] [2] Plastics that act as pollutants are categorized into micro- meso- or macro debris, based on size. [3].
