What are the effects of nitrogen dioxide?
What are the effects of nitrogen dioxide?
Elevated levels of nitrogen dioxide can cause damage to the human respiratory tract and increase a person’s vulnerability to, and the severity of, respiratory infections and asthma. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease.
What happens when exposed to nitrogen dioxide?
Exposure to nitrogen oxides may result in changes of the pulmonary system including pulmonary edema, pneumonitis, bronchitis, bronchiolitis, emphysema, and possibly methemoglobinemia. Cough, hyperpnea, and dyspnea may be seen after some delay.
How does nitrogen dioxide affect the climate?
Nitrogen emissions such as ammonia, nitrogen oxide and nitrous oxides contribute to particulate matter and acid rain. Nitrous oxide is a particularly potent greenhouse gas as it is over 300 times more effective at trapping heat in the atmosphere than carbon dioxide.
What damage can nitrogen dioxide cause in the atmosphere?
NO2 and other nitrogen oxides in the outdoor air contribute to particle pollution and to the chemical reactions that make ozone. It is one of six widespread air pollutants that have national air quality standards to limit them in the outdoor air.
Can you smell nitrogen dioxide?
Nitrogen dioxide is reddish-brown with a very harsh smell at high concentrations, at lower concentrations it is colorless but may still have a harsh odour.
What causes high nitrogen dioxide levels?
Nitrogen dioxide comes from vehicles, power plants, industrial emissions and off-road sources such as construction, lawn and gardening equipment. All of these sources burn fossil fuels. People who live or work near busy roadways can experience high exposures.
What happens if you have too much nitrogen in your body?
Uremia is life-threatening because too much nitrogen in the blood is toxic to the body. Symptoms of uremia include confusion, loss of consciousness, low urine production, dry mouth, fatigue, weakness, pale skin or pallor, bleeding problems, rapid heart rate (tachycardia), edema (swelling), and excessive thirst.
What causes nitrogen dioxide in the air?
Nitrogen dioxide comes from vehicles, power plants, industrial emissions and off-road sources such as construction, lawn and gardening equipment. All of these sources burn fossil fuels.
What is nitrogen dioxide used for?
What is nitrogen dioxide used for? Nitrogen Dioxide, NO 2; was used as a catalyst in some oxidation reactions; as an inhibitor to prevent the polymerization of acrylates during distillation; as an organic compound nitrating agent; as an oxidizing agent; as a rocket fuel; as a flour bleaching agent.
Where is nitrogen dioxide found?
Road traffic is the principal outdoor source of nitrogen dioxide. The most important indoor sources include tobacco smoke and gas-, wood-, oil-, kerosene- and coal-burning appliances such as stoves, ovens, space and water heaters and fireplaces, particularly unflued or poorly maintained appliances.
Is nitrogen dioxide a carcinogen?
The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified nitrogen oxides for potential carcinogenicity.
Is there a safe level of nitrogen dioxide?
According to the Occupational Safety and Health Administration (OSHA)2, the permissible exposure limit for NO2 in homes and offices should not exceed 5 ppm (9 mg/m3). However, NO2 levels as low as 0.1 ppm have been shown to cause respiratory discomfort in vulnerable populations such as asthmatics.
What are the effects of Nitrogen Dioxide ( NO 2 )?
2 can cause respiratory effects including airway inflammation in healthy people and increased respiratory symptoms in people with asthma. NO 2 creates ozone which causes eye irritation and exacerbates respiratory conditions, leading to increased visits to emergency departments and hospital admissions for respiratory issues, especially asthma.
What is the phase diagram of nitrogen gas?
The phase diagram of nitrogen is shown below the table. Follow the links below to get values for the listed properties of nitrogen at varying pressure and temperature: Nitrogen is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid.
How does nitrogen dioxide get into the air?
Nitrogen Dioxide (NO 2) is one of a group of highly reactive gases known as oxides of nitrogen or nitrogen oxides (NO x ). Other nitrogen oxides include nitrous acid and nitric acid. NO 2 is used as the indicator for the larger group of nitrogen oxides. NO 2 primarily gets in the air from the burning of fuel.
What can you do to stop the flow of nitrogen dioxide?
Nitrogen dioxide is non-flammable but supports combustion. Wearing proper equipment, shut off flow of gas. Use water spray to keep containers cool and to direct escaping gas away from those effecting shut off.
