Conclusion
All three studies demonstrate that acid rain pollution has numerous
connections and is quite complicated, especially in its origins, effects
and solutions. A first study explains that simulation of acid rain
increases the leaching of arsenic compounds from industrial waste which
harms both the environment and groundwater. Using the
leaching-crystallization method, it was found that these hazardous
residues could be stabilized, thus stressing the importance of treating
residues in areas with acid rain.
Although pollution controls reduced acid gases in the air, acid rain in
Guilin did not get any better and instead, got worse. It happened
because simultaneously, the number of alkaline elements in the air which
normally neutralize rain’s acids, decreased. To keep acid rain under
control, the study encourages using methods that handle both the
releasing chemicals and the substances that counter their effects.
All of these points show that acid rain prevention relies on a broad and
equal approach. Actions to limit greenhouse gas emissions should cover
burning fossil fuels and agriculture, along with looking at and managing
the balance of chemicals in the air. Also, they point out that it is
important for countries to work together locally and regionally since
pollutants can be carried to other regions and affect the chemistry of
rain. Creating better environmental standards, applying leading
treatment methods and updating monitoring are important parts of
strategy to help both the environment and health.
