with the first section covers the common nitrogen oxides, followed by the sources and potential sinks in the environment, then the chemical behaviour of these oxides, the impacts on human and ecosystem, and finally the prevention and control of these pollutants.
Nitrogen oxides mainly consist of nitrogen and oxygen, and the most common nitrogen oxides are nitric oxide (NO) and nitrogen dioxide (NO2) (Farmer 2013, p.26; Harrison 2001, p.179). Notably, nitrous oxide and nitrogen dioxide are emitted when nitrogen reacts with oxygen in the air during combustion at high temperatures and this shows that the amount of nitrogen oxides produced depends on temperature of combustion. Another nitrogen oxide is nitrous oxide (N2O) which is a greenhouse gas that has a greater impact on climate change. Nitric oxide is a colourless gas with a sharp and sweet smell, but nitrogen dioxide is a colourless gas with a strong, harsh odour. Of the nitrogen oxides emitted, nitric oxides forms the larger part, followed by nitrous oxide then nitrogen dioxide which is produced in low amounts, and also it is important to note that both nitric oxide and nitrogen dioxides does not have prolonged lifespan in the atmosphere as compared to nitrous oxide.
Nitrogen oxides are produced naturally but they are as well produced by various human activities including agricultural activities, transportation and industrial processes and many others. In nature, nitrogen oxides are produced because of bacterial processes, biological growth and decay, forest fires (Lippmann 2009, p.823), volcano, and lightening among others (Hill 2010, p.128). Thunderstorms lead to the production of nitric oxide as a result of high heat of lightening released in the process of breaking down nitrogen molecules. On the other hand, burning of fossil fuels is considered the primary source of nitrogen oxides as part of human activities.
Transportation fuels when burned produce nitrous oxide and mostly, motor vehicles and trucks

The paper seeks to answer the question: What are we going to do to solve environmental problems? We cannot simply be ignorant to problems and turn our backs to the problems that currently exist in far-away place from us. The reason we cannot ignore problems is because it would not be ethical, and it is impossible that we will not be affected at some point in some way.
Substances found in diesel exhaust may include harmful substances like fine particulate matter, hydrocarbons, nitrogen oxides, carbon monoxide, as well as similar air contaminants. Where solids and liquid droplets mix together, particle or particulate pollution (PM) is often seen.
The prime sources are burning fuels, for example , petrol or diesel in a car engine, or natural gas when it is burned at homes for central heating or at a major scale, in power stations (Harrison 2001, p. 179). Naturally, though, it is formed by the electrostatic reaction of lightening and by plants and other vegetation.
(Wijetilleke & Karunaratne, 1995, p.10) There are many types of air pollution. The common types are acid rain, smog, greenhouse effect and damage in ozone layer. All these types can cause serious damage to human health (What is Air Pollution, n.d.). There are two main air pollutants that cause most damage to human beings and environment.
This essay refers to Beijing Municipal Environmental Monitoring Center, that reports current quality of air is above 300, which is considered hazardous by the World Health Organization. The researcher also discusses causes of air pollution, such as dense smog in the atmosphere and impacts on the people of Beijing.
With the tool, it allows for objective monitoring of asthma attacks without the need of comprehensive articulation. The use of nitric oxide in this field is based on the pathophysiological, physical, molecular and genetic researches that have the role of nitric oxide in respiration and related diseases (Gill et al, 2005).
The use of fertilizers in agriculture, pollution and other human interventions has resulted in increased concentrations of the gas in the atmosphere and work places that has instilled fear for environmental /health safety.
In this context, monitoring Nitrous oxide concentrations becomes pertinent.
The author of the essay highlights some of the sources of air pollution and provides means of regulating them. Most of the sources of air pollution arise from technological and industrial advancement made by humans. The research also reveals that air pollution is indeed a major problem in many regions of the world.
Furthermore, many areas of human life would be vulnerable to potential dangerous scenarios unless proactive engineering efforts are initiated towards identifying and resolving those issues. This paper will discuss the engineering
