Science of the Health Effects of FibersAn introduction to fiber biology, chemistry, and physics

Is there a Scientific Question?

Before we ask why different kinds of fibers yield different responses when people are exposed to them, we need to show that there really is a big difference that needs a scientific explanation. There are now several studies available that show these differences clearly including these results from chronic inhalation studies. Our Fiber science page is an introduction to the biology, chemistry, and physics of fibers in the lung.

Dissolution Rate Calculator

The theory behind the fiber dissolution rate calculator is from composition has been published in a series of papers and will be outlined here. It is based on the Arrhenius equation in which the logarithm of a reaction rate constant is proportional to the free energy required to initiate the process.
