“Microplastics”

Microplastics are very small pieces of plastic that pollute the environment.  According to the U.S. National Oceanic and Atmospheric Administration (NOAA) microplastics are less than 5mm in length. Other plastics are internationally designed to be small, they are called microbeads. Microbeads are tiny pieces of polyethylene plastic added to health and beauty products. Microplastics are not biodegradable.
Text Box:                                                Figure 1:- Structures of microplastics
Microplastics consist of Carbon and Hydrogen atoms bound together in polymer chains. Other chemicals such as Phthalates, Polybrominated biphenyl ethers (PBDE s) and tetrabromobisphenol A (TBBPA) are typically also present in microplastics.

There are two types of Microplastics.
Ø  Primary Microplastics

Ø  Secondary Microplastics


There are countless sources of both primary and secondary microplastics.




v Primary Microplastics

Primary microplastics fibres enter to the environment from the washing synthetic clothes. Such as polyester, nylon etc…Did you think washing clothes may affect to the future? I know even you can’t believe.

Do you know usually some companies have used microplastics (microbeads) to produce some tooth pastes, cleansers, and other cosmetics products? Think, how much of cosmetics you use in daily. Not only you but also your family also. Think daily consumption of microplastics in the world. Can you count how much of microplastics may release to the environment?  You can’t. Many people talk about the environmental pollution. But I think all people in the world have released microplastics to the environment. Isn’t that include to the environmental pollution?


I think we all have use even toothpastes with microplastics.








 


Anyway on December 28.2015, president Obama signed to the microbeads free waters act of 2015, banning plastic microbeads in cosmetics and personal care products. But microplastics are still a huge problem.

Also primary microplastics release from plastic pellets which is used in industrial manufacturing.
Some microplastics scrubbers using at machinery, engines, and boat hulls to remove rust and paint.

v Secondary Microplastics

Form from the breakdown of larger plastics. Such as wave action, Wind abrasion and ultraviolet radiation from sunlight.


v What will happen to the Live Organisms?

Microplastics also are a source of air pollution, occurring in dust and airborne fibrous particles.  The health effects of microplastics inhalation are unknown.
Aquatic life and birds likely to eat which are floating on the water surface. That foods will be exactly contaminated with microplastics. So they mistaking the plastic bits for food. 


 By 2018, in marine and freshwater ecosystems combined, microplastics had been found in more than 114 aquatic species. Microplastics have been found lodged in the digestive tracts and tissues of various invertebrate sea animals, including Crustaceans such as crabs, fish and birds. The ingestion of microplastics can cause aquatic species to consume less food and therefore to have less energy to carry out life functions and it can result in  neurological and reproductive toxicity.







 

Think about what will happen to us after consuming fish and other aquatic organisms.
Anyway entire cycle and movement of microplastics in the environment is not yet known. But research is currently underway to investigate this issue.



v How to overcome?

·         There are some campaigns conducting for raising awareness of plastic pollution and encouraging reuse, and recycling of plastics.

·         Can ban the microbeads containing cosmetic products.


·         Remediation of microplastics already in the environment.
  Strategies under investigation included the use of microorganisms capable of breaking down synthetic microplastic polymer. A number of bacterial and fungal species possess biodegradation capabilities, breaking down chemicals such as polystyrene, polyester, polyurethane and polyethylene. Such microorganisms potentially can be applied to sewage waste water and other contaminated environment.

Any way you can reduce the microplastics in the earth.
Follow,

Reduce
Reuse
Recycle
