>>14338621From the new paper, the mean of the sum quantifiable concentration of plastic particles in blood was 1.6 µg/ml, and the blood volume of about 5 liters, then you have 8000µg or 8mg in the bloodstream.
>"Our operationally defined method targeted particles that could beretained on a filter with pore size of 700 nm, i.e. particles ?700 nm
in dimension. The inner diameter of the needle used for venipuncture
(0.514 mm) can be considered the upper size limit of particles this
method could sample."
It means they weren't measuring anything smaller than 700nm, and a
single "mer" is surely smaller than that and many biological processes
occur under 700nm scales.
>Older research: "The research builds on previous work that has alsoshown that microplastics are making their way through our bodies. A
2019 study found that 97 percent of blood and urine samples collected
from some 2,500 children in Germany between the ages of three and 17
showed toxic levels of plastic byproducts. A 2018 study showed similar
results: 20 particles of plastic per ten grams of human stool
samples."
What can you do? Get away from cars- the tires are continually disintegrating mp's. Running around outside isn't going to help: Airway infiltration is probably the key pathway into the bloodstream via the lungs. There is a continuous concentration in the air, it is visible as dust on surfaces. Distance from emissions sources is probably the best strategy, but you are exposed everywhere on the planet now. A HEPA filter filtering fresh air with good sealing around doors and windows will help. Ban pic related- all they are doing is putting microplastics (and other shit) into the air column (reversing sedimentation processes).
Right now we simply don't know what effects it is having. As methods of detection improve, we will start finding it everywhere- we already know experimentally it can cross the blood brain barrier in the rat model.
