We are working on a system based on data analysis which thanks to technology which involves Raman Spectroscopy, we can detect the amount of microplastics (and the type of it, even if they are polymers or other material). Even though we have done a modification on the Raman to apply it to solids and it requires less complex analysis, we have to take into account the amount of analysis we are doing per day.
To make this calculation, first we are considering the volume of aspirated air in 2 h by the air pump:
We are able to see the volume the vaccum will absorve. Knowing the distribution of people in the room.
We will be using 1 filter per 4 people, what means having 0.25 filter per person.
Then:
100 people/room -> 25 Filter
200 people/room -> 50 Filter
In first place, we have to be aware of our Rate 15.0 ± 0.1 L/min. If we are using it between 1 h and 2.5 h (Depending on the room space), we won’t block up the poruses of the filter.
This is the schematic of the table with which we are basing the calculations.
The concentration obtained on the Raman spectrocopy is not the same than the one that a person would have inhalated in that time.
When the Ramman spectrosopy will give us the concentration we will have to apply the relation to know the real value of inhalation of the people.
We put the filter on the table for three main reasons:
“Empowering Vietnam textile factories workers by reducing their overexposure to microplastics to avoid lung disseasses.”
