Development of Atmospheric Microplastic Analysis Technology for Future Environmental Protection
Microplastics Contaminating the Air! What Are the Impacts on Our Health?
It has been about 150 years since humanity first created plastics, and today, over 400 million tons are produced annually. With this increase in production, plastic waste has also surged, leading to the spread of microscopic plastic particles that have become a global environmental issue as microplastics. Microplastics in the air have the potential to be inhaled by humans through respiration, and understanding their dynamics and effects on health is crucial.
Visualizing Microplastics in the Air! Development of New Analytical Methods
Traditional methods such as infrared absorption spectroscopy and Raman spectroscopy have faced challenges in completely tracking particulate matter in the air due to limitations like the diffraction limit of light. To address this, we are developing a new analytical technique using Pyrolysis Gas Chromatography/Mass Spectrometry (Py-GC/MS). This method allows us to analyze small amounts of plastic components without being affected by particle size.
Thoroughly Analyzing Particles in the Air! Getting Closer to the Mystery of Plastics
We classify particles in the air based on their aerodynamic diameter, and after collecting them using quartz fiber filters, we perform direct analysis. This approach allows us to detect even trace amounts of plastic components with high sensitivity, eliminating the influence of other co-existing substances. Furthermore, our analysis covers a wide range of plastic and rubber types, aiming for a comprehensive analysis.
A Key to Combating Air Pollution! The Importance of Microplastic Analysis
By implementing this method, we can evaluate the mass of plastic and rubber components per unit volume of air and measure the potential health impacts, such as those from PM2.5. Additionally, this enables international data comparison, enhancing our understanding of the movement and impact of microplastics in the atmosphere. Ultimately, this research could lead to determining the acceptable levels of plastic in the air, paving the way for concrete environmental action.
Towards a Future Without Microplastic Pollution! Innovation Leads the Way
The Py-GC/MS technique not only analyzes plastic and rubber components but can also be applied to study additives. This technology is at the forefront globally, and it is undoubtedly poised to become a key technology for addressing future environmental challenges.
