Why do the low-cost optical sensors claimed to measure particle mass while the optical signal is not proportional to mass at all?

I am not a expert in optical. But I read that the optical intensity is either proportional to particle diameter to the 6 for particles smaller than 1 micron meter or particle diameter to the 2...

Are there any mechanism by which the relationship between aerosol nanoparticle penetration (P) and particle size (D) is: P=aD, where a is constant?

P=aD (power law that power is 1) that means larger particle have higher penetration through something. The nanoparticle size is between 20-500 nm.
