SulphuR dioxide or nitrogen dioxide...this can kill fish by making lakes acidic!
Carbon Dioxide is always in the atmosphere, so all rain has some carbonic acid in it.

When water vapor and sulfur dioxide combine in the air, they can form sulfuric acid, a major component of acid rain. This can have harmful effects on the environment by damaging vegetation, aquatic life, and infrastructure. Controlling emissions of sulfur dioxide is key to mitigating the impacts of acid rain.
The two main components of acid rain are sulfur dioxide(SO2) and nitrogen oxides (NOx).Sulfur dioxide is a colorless gas released by combusting fossil fuels that contain sulfur.Sulfur dioxide reacts with the moisture in the atmosphere to form sulfur trioxide.Sulfur trioxide then joins with water to form Sulfuric Acid.
Sulfur dioxide (SO2) emissions react with water in the atmosphere to form sulfuric acid (H2SO4), a major component of acid rain. When acid rain falls, it can lower the pH of soil and water bodies, leading to harmful effects on aquatic life, vegetation, and infrastructure. The release of sulfur dioxide from human activities such as burning fossil fuels is a significant cause of acid rain.
acid rain; SO2, i.e. sulfur dioxide, reacts with water to produce H2SO3, or sulfurous acid, which then reacts with oxygen to form sulphuric acid (H2SO4), and dissolves in rain to fall as acid rain
nitric and sulfuric acids
The element is sulfur. When coal containing sulfur is burned, it forms sulfur dioxide, a gas that reacts with water in the atmosphere to form sulfuric acid, a major component of acid rain.
NO2 and SO2
Acid rain
Acid rain is a result of chemicals such as sulfur dioxide and nitrogen oxides, often contained in coal, mixing and reacting with the oxygen, hydrogen, and water in the air resulting in acid such as sulfuric acid and nitric acids. The result is the acids dissolved in the rain drops. This acid rain can have corrosive effect on plant and animal life as well as man made art and structures. Carbon Water
I believe a major component is formic acid.
