Nitrogen Oxides | Center for Science Education

Nitric oxide is a colorless, flammable gas with a slight odor. Nitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. It, along with aerosols, is responsible for the reddish-brown color of smog. At high concentrations it is highly toxic, and can cause serious lung damage. Nitrogen dioxide is a strong oxidizing agent, and ...

Sulfur dioxide | Minnesota Pollution Control Agency

Sulfur dioxide. Sulfur dioxide (SO2), a foul-smelling toxic gas, is part of a larger group of chemicals called sulfur oxides. These gases, especially SO2, are emitted by the burning of fossil fuels or other materials that contain sulfur. Sulfur dioxide can damage trees and plants, inhibit plant growth, and damage sensitive ecosystems and waterways.

How to Control Sulfur Oxide Emissions in Smelting

Currently, there are three methods in use for reducing the sulfur dioxide concentration in the atmosphere surrounding a smelter. They are: (1) the tall stack; (2) the tall stack coupled with a contact sulfuric acid plant; and (3) closed-loop control. Of the three methods, the tall stack is the simplest.
