Inflammation of the aveoli, which may arise from raising poultry and engaging in farm labour is also now covered, in addition to diseases arising from exposure to zinc, copper, tin, organic solvents, and pharmaceutical products, in addition to the inhalation of carbon dioxides and metal resources.
This damage makes the aveoli less elastic and, therefore, less effective at passing oxygen into the blood and removing carbon dioxide from the blood, leading to shortness of breath.
He said this opens aveoli (air sacs) in our lungs to allow more efficient oxygen uptake for each breath.
Doctors have long been concerned about fine particulates because they get drawn into the aveoli, the lung's smallest air sacks, where they remain, causing potential damage over long periods of time.
