Eight percent of world oil production goes to manufacturing plastics. If the product were made of excessive packaging that used a lot of virgin materials, it would get a red dot. Centers for Disease Control and Prevention reported that 93 percent of people had detectable levels of BPA in their urine.
This way you can help in contributing towards the environment in the form of reducing plastic pollution whose ill effects are irreversible.
As land becomes more valuable, just finding a place to put garbage is becoming a problem in many parts of the world. Research on experimental animals informs epidemiologists about the potential for adverse effects in humans and thus plays a critical role in chemical risk assessments.
Not to throw used plastic here and there e. To destroy plastics, we can either recycle or burn them. But some of these chemicals have been shown to affect reproduction and development in animal studies, according to the report. Short Article on Plastic Hazards Article shared by: Plastic is an incredibly useful material, but it is also made from toxic compounds known to cause illness, and because it is meant for durability, it is not biodegradable.
The process of recycling plastic can also lead to plastic irritants being released in a number of ways. Some studies also have linked these chemicals with adverse effects in people, including reproductive abnormalities.
We look at how the environment affects our health through environmental epidemiology, collect and share environmental health data, and provide support to state and local environmental health practitioners. Production, usage, disposal and waste management solutions Accumulation of plastic debris in the environment and the associated consequences are largely avoidable.
Hence, more information is required on the biological mechanisms that may be affected by plastic additives and in particular, low-dose chronic exposures. It can also get stuck on poles, traffic lights, trees, fences, tower etc. These kinds of occurrences have caused deaths, injuries, evacuations and major property damage.
Problem chemicals are used as plasticizers, antioxidants, colorants, flame retardants, heat stabilizers, and barrier resins. Such substances may be toxic. The report also suggests that plastic waste can be reduced by using labels that allow consumers to choose packaging based on a lifecycle analysis that includes all components of the manufacturing process.
In addition to the physical problems associated with plastic debris, there has been much speculation that, if ingested, plastic has the potential to transfer toxic substances to the food chain see Teuten et al.
This has had terrible consequences on many marine species, which can lead to consequences for those that eat fish and marine life for nutrients — including people.
But the synthetic material also has left harmful imprints on the environment and perhaps human health, according to a new compilation of articles authored by scientists from around the world. Global warming further aids the process by making previously inhospitable areas like the Arctic livable for invasive species, which can be detrimental to local species.
However, ingestion is likely to be particularly problematic for species that specifically select plastic items because they mistake them for their food. These effects include direct toxicity, as in the cases of lead, cadmium, and mercury; or carcinogens, as in the case of diethyl hexylphosphate DEHP.
The durability of plastics and their potential for diverse applications, including widespread use as disposable items, were anticipated, but the problems associated with waste management and plastic debris were not. 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.
These initiatives include container deposit laws and landfill use-reduction laws. There is also a need for industry and independent scientists to work more closely with, rather than against, each other in order to focus effectively on the best ways forward.
Still, there is already evidence that chemicals associated plastics might harm wildlife. Laboratory experiments have shown that small pieces such as these can be ingested by small marine invertebrates including filter feeders, deposit feeders and detritivores Thompson et al.
If those substances turn out to be persistent e. Effects observed in the laboratory coincide with measured environmental concentrations, thus there is a very real probability that these chemicals are affecting natural populations Oehlmann et al.
The greatest concerns with exposure to BPA are during development; BPA appears to affect brain development leading to loss of sex differentiation in brain structures and behaviour Talsness et al. As noted by these authors and others, there is a need to integrate concepts of endocrinology in the assumptions underlying chemical risk assessment.
In addition to the reliance on finite resources for plastic production, and concerns about additive effects of different chemicals, current patterns of usage are generating global waste management problems.Environmental and health hazards of chemicals in plastic polymers and products Delilah Lithner, Department of Plant and Environmental Sciences.
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 - Plastic bags- an environmental hazard The problem created by the use of plastics bags is primarily due to shortcomings in the waste management system.
Indiscriminate chemical additives pose environmental problems including choking open drains, ground water contamination, etc. Living on Earth is an independent media program and relies entirely on contributions from listeners and institutions supporting public service.
Please donate now to. Pollution and hazards from manufacturing The most obvious form of pollution associated with plastic packaging is wasted plastic sent to landfills.
Plastics are very stable and therefore stay in the environment a long time after they are discarded, especially if they are shielded from direct sunlight by. The second option, incineration, returns some of the energy from plastic production but is known to produce negative environmental and health effects.
Many plastics can be recycled, and some of the materials used to make plastics can be recovered.Download
