What is it about?

Microplastics and Nano-particles ( MNP’s) surround us, not only found in the natural external environment but are also found within our very own internal environment (our tissues). As the world has entered the 21st century and as technology has advanced, the use of plastics predominantly single-use plastics (which are polymeric materials) has rapidly increased to match the global demand and the lifestyle habits as well as creature comforts which are demanded by the modern human being.

Why is it important?

Microplastics and Nano-particles ( MNP’s) interact with our environment and affect our health. However our knowledge with regards to these MNP’s still has major gaps and further research is necessitated to understand their full effect on our bodies and natural environment. Micro-plastics and nanoparticles are also known as MNP’s, for a piece of plastic to be considered a “microplastic” it must be less than 5mm in length and a nanoparticle is deemed one if it ranges between 1 to 1000 nanometers in size. The ubiquitous nature of these MNP’s within our environment poses a threat both directly and indirectly to the human race. The majority of these plastic polymeric compounds are produced from petro-chemicals and have innate substances and toxins which contaminate organic living matter.

Perspectives

It is clearly evident that MNP’s have a detrimental effect on cardiovascular health, the extent to which is unclear. Further larger scale studies are required and are imperative to providing an improved insight for legislation and governing action.
