Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life ...
The air pollutants released from the burning of fossil fuels usually comes back to earth in the form of acid rain. Acid rain is a form of precipitation which has high sulfuric and nitric acids, which can also occur in the form of a fog or snow. Acid rain has numerous ecological impacts on streams, lakes, wetlands and
Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [66]
The term/s acid gas and sour gas are often incorrectly treated as synonyms. Strictly speaking, a sour gas is any gas that specifically contains hydrogen sulfide in significant amounts; an acid gas is any gas that contains significant amounts of acidic gases such as carbon dioxide (CO 2) or hydrogen sulfide. Thus, carbon dioxide by itself is an ...
In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries. The carbon dioxide content of the blood is often given as the partial pressure , which is the pressure which carbon dioxide would have had if it alone occupied the volume. [ 73 ]
The higher sulfuric acid content of rain also may not release as much Al 3+ from soils as does nitric acid, in part due to the retention (adsorption) of SO 4 2-by soils. This process releases OH − into soil solution and buffers the pH decrease caused by the added H + from both acids. The forest floor organic soil horizons (layers) that are ...
Alcohol education is the planned provision of information and skills relevant to living in a world where alcohol is commonly misused. [3] WHO Global Status Report on Alcohol and Health, highlights the fact that alcohol will be a larger problem in later years, with estimates suggesting it will be the leading cause of disability and death.
