ENV-400: Air pollution and climate change

A survey course describing the origins of air pollution and climate change ...

Description

This lecture covers the formation of air pollutants such as NO₂ and HNO₃, their direct and indirect health effects, the production of N₂O, and the reduction strategies using 3-way catalysts and SCR. It also discusses the Volkswagen emissions scandal and the measurement techniques for nitrogen oxides. The presentation includes information on the history of ozone detection, the impact of air pollutants on the environment, and the regulations governing air quality.

Expertise atmospheric science, aerosol-cloud interactions, climate change in polar regions Mission Extreme environments are particularly sensitive to climate change and are transforming at accelerated rates. This can have important global repercussions. EERL aims to create integrated process understanding by investigating interactions between the atmosphere, cryosphere, biosphere, ocean, land and anthroposphere. The goal is to characterize climate-change relevant and vertically-resolved processes that are d

Air pollution

Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of indoor or outdoor surrounding either by chemical activities, physical or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules.

Vehicle emissions control

Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines. Emissions of many air pollutants have been shown to have variety of negative effects on public health and the natural environment. Emissions that are principal pollutants of concern include: Hydrocarbons (HC) – A class of burned or partially burned fuel, hydrocarbons are toxins. Hydrocarbons are a major contributor to smog, which can be a major problem in urban areas.

Vehicle emission standard

Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human life. Different regions and countries have different standards for vehicle emissions. Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles.

Nitrogen oxide

Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds: Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide Nitrogen dioxide (), nitrogen(IV) oxide Nitrogen trioxide (), or nitrate radical Nitrous oxide (), nitrogen(0,II) oxide Dinitrogen dioxide (), nitrogen(II) oxide dimer Dinitrogen trioxide (), nitrogen(II,IV) oxide Dinitrogen tetroxide (), nitrogen(IV) oxide dimer Dinitrogen pentoxide (), nitrogen(V) oxide, or nitronium nitrate Nitrosyl azide (), nit

Nitrogen dioxide

Nitrogen dioxide is a chemical compound with the formula NO2. It is one of several nitrogen oxides. NO2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantities. Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry. It is included in the NOx family of atmospheric pollutants.
