NONE as PVC cannot be exposed to direct sun light. A much better choice would be cast iron piping with a CI drain and lead caulked joints which will not dry out and are acid resistant from acid rain and bird droppings
Harmful.
To understand acid deposition's causes and effects, and to track changes in the environment, scientists from EPA, state governments, and academia study acidification processes. They collect air and water samples and measure them for various characteristics such as pH and chemical composition, and research the effects of acid deposition on human-made materials such as marble and bronze. Finally, scientists work to understand the effects of sulfur dioxide (SO2) and nitrogen oxides (NOx)-the pollutants that cause acid deposition and contribute to particulate matter -on human health. See the acid rain effects section for more information. To solve the acid rain problem, people need to understand how acid rain damages the environment. They also need to understand what changes could be made to the air pollution sources that cause the problem. The answers to these questions help leaders make better decisions about how to control air pollution and therefore, how to reduce-or even eliminate-acid rain. Because there are many solutions to the acid rain problem, leaders have a choice of which options or combination of options are best. The next section describes some of the steps that can be taken to tackle the acid deposition problem.

No such thing as a galvanized iron roof. They are galvanized steel. The sound is distinct and as I cannot post audio it is impossible to describe the sound. But if you will click the link you can hear it.
The surfaces can be passivated with polymers but existing damage probably cannot be repaired.
There is no such thing as acid rain but you can make drops of acid depending on its pH level on top of iron.
When acid rain touches iron, a chemical reaction occurs that causes the iron to corrode or rust. The acid in the rain reacts with the iron to form iron oxide, which weakens the metal and can eventually lead to its deterioration and structural damage.
Yes, acid rain can affect the cell structure of Spirogyra algae. The acidic nature of acid rain can disrupt the cell membrane and inhibit photosynthesis, which can ultimately lead to damage or death of the algae.
Acid rain can damage skin of a person.
Acid rain can gradually erode and deteriorate the surface of granite by reacting with the minerals in the rock. This can lead to discoloration, pitting, and weakening of the structure over time. Additionally, acid rain can also contribute to the degradation of any protective coatings or sealants applied to the granite surface.
The acid rain can dissolve marble and is corrosive for iron railway lines.
Yes, acid rain does affect germination of seeds by mixing in with the soil and damaging the seed coating.
Acid rain can have a devastating affect on the desert. This acid can wear through the plants protective layer and it will then die in the sun.
It wears the structure down to nothing. Particularly those made of limestone.
We build factories that create pollution; in some cases acid rain
it burns it
yes, it can
