What is Acid Rain? | US EPA

Acid rain results when sulfur dioxide (SO 2) and nitrogen oxides (NO X) are emitted into the atmosphere and transported by wind and air currents.The SO 2 and NO X react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground. While a small portion of the SO 2 and NO X that cause acid rain is from ...

How to Acid Etch Steel: 11 Steps (with Pictures) - wikiHow

Nitric acid is commonly mixed in a ratio of 1 part nitric acid to 3 parts water. It can also be mixed with acetic acid (vinegar), in a 1 to 1 ratio, or with hydrochloric acid. Sulfuric acid should be used only in concentrations from 10 to 25 percent. Generally, dilute solutions are more effective than concentrated ones.

Steel Mill Workers - Mesothelioma & Asbestos Exposure Risks

Steel Mill Workers and Mesothelioma. When workers inhaled asbestos fibers, some would become lodged in the lungs and pleural lining of the lungs, often causing scarring and damage that led to tumor formation later in life. Many workers were eventually diagnosed with mesothelioma cancer.

The Parietal Cell: Mechanism of Acid Secretion

Mechanism of Acid Secretion. The hydrogen ion concentration in parietal cell secretions is roughly 3 million fold higher than in blood, and chloride is secreted against both a concentration and electric gradient. Thus, the ability of the partietal cell to secrete acid is dependent on active transport.

What materials are used to make wind turbines?

According to a report from the National Renewable Energy Laboratory, wind turbines are predominantly made of steel (71-79% of total turbine mass); fiberglass, resin or plastic (11-16%); iron or cast iron (5- 17%); copper (1%); and aluminum (0-2%). Many turbine components are domestically sourced and manufactured in the United States (Wind Technologies Market Report).

Types of Batteries Used for Electric Vehicles

Both lead acid batteries and nickel metal hydride (NiMH) batteries are mature battery technologies. These types of batteries were originally used in early electric vehicles such as General Motor's EV1. However, they are now considered to be obsolete with regards to their uses as the main source of energy storage in BEVs.
