What are the short-term and long-term outcomes of Sulphur Dioxide or health problem if not treated?

My answer:
short term effects:
Acute effects to high levels can possibly burn the skin and eyes and
may result in permanent eye damage. High levels may also cause
pulmonary edema (when the lungs fill up with fluid). This is a true
medical emergency since oxygen cannot get through the fluid so the
person may die. S02 can also cause the airway passages in the lung to
narrow resulting in wheezing, chest tightness, or breathing problems.

In severe cases where very high concentrations of SO2 have been
produced in closed spaces, SO2 has caused severe airways obstruction,
hypoxemia (insufficient oxygenation of the blood), pulmonary edema (a
life threatening accumulation of fluid in the lungs), and death in
minutes. The effects of pulmonary edema include coughing and shortness
of breath which can be delayed until hours or days after the exposure.
These symptoms are aggravated by physical exertion. As a result of
severe exposures, permanent lung injury may occur.


long-term
"Repeated, long-term exposure to lower levels of sulfur dioxide may:
Decrease pulmonary function
Cause bronchitis to develop with cough and phlegm production"
Long-term exposure to persistent levels of sulfur dioxide can affect
your health. Lung function changes were seen in some workers exposed
to low levels of sulfur dioxide for 20 years or more. However, these
workers were also exposed to other chemicals, so their health effects
may not have been from sulfur dioxide alone. Asthmatics have also been
shown to be sensitive to the respiratory effects of low concentrations
of sulfur dioxide.

Animal studies also show respiratory effects from breathing sulfur
dioxide. Animals exposed to high concentrations of sulfur dioxide
showed decreased respiration, inflammation of the airways, and
destruction of areas of the lung."
