Motor vehicle emissions contribute to ambient levels of air toxics known or suspected as human or animal carcinogens. Exposures to air toxics can also cause noncancerous health effects, such as neurological, cardiovascular, respiratory, reproductive and/or immune system damage .
How gases that cause air pollution affects human health?
They can increase the risk of heart and respiratory diseases, as well as lung cancer . Ozone is a major factor in causing asthma (or making it worse), and nitrogen dioxide and sulfur dioxide can also cause asthma, bronchial symptoms, lung inflammation and reduced lung function.
How do emissions affect health?
Relationship to public health
Vehicle emissions contribute to the formation of ground level ozone (smog), which can trigger health problems such as aggravated asthma, reduced lung capacity, and increased susceptibility to respiratory illnesses, including pneumonia and bronchitis .
How does CO2 emissions affect human health?
Exposure to CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions .
How does climate affect human life?
The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience .
How does climate change global warming affect human health?
Hot temperatures increase the ozone concentration, which can damage people’s lung tissue and cause complications for asthma patients and those with lung diseases . Increased global warming can also pose a threat to national security, affecting food security, which, in turn, can lead to resource conflicts.

- the person’s individual characteristics and behaviours.
How does vehicle pollution affect humans?
Air pollutant emissions, such as hydrocarbons, oxides of nitrogen and particulate matter can lead to smog and adverse health impacts such as respiratory illness, cardiovascular disease and cancer .
Is CO2 toxic to humans?
At low concentrations, gaseous carbon dioxide appears to have little toxicological effect . At higher concentrations it leads to an increased respiratory rate, tachycardia, cardiac arrhythmias and impaired consciousness. Concentrations >10% may cause convulsions, coma and death.
What level of CO2 is harmful to humans?
This could occur when exposed to levels above 5,000 ppm for many hours. At even higher levels of CO 2 can cause asphyxiation as it replaces oxygen in the blood-exposure to concentrations around 40,000 ppm is immediately dangerous to life and health.
What are the diseases caused by climate change?
The major mosquito-borne infectious diseases that have been reported to be affected by global warming include malaria, dengue fever, Japanese encephalitis (JE), and tick-borne encephalitis .
How does climate change affect humans and animals?
Impacts. Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.
How does climate change affect human health in India?

How does climate affect mental health?
The mental health consequences of events linked to a changing global climate include mild stress and distress, high-risk coping behavior such as increased alcohol use and, occasionally, mental disorders such as depression, anxiety and post-traumatic stress .
How does climate change affect respiratory health?
Climate change increases water and air pollution which can cause and aggravate chronic respiratory disease, such as asthma . Increased temperatures due to climate change lead to increased ground-level ozone, which cause airway inflammation and damages lung tissue.
What are the 5 effects of global warming?

What diseases can air pollution cause?
Ambient air pollution accounts for an estimated 4.2 million deaths per year due to stroke, heart disease, lung cancer and chronic respiratory diseases . Around 91% of the world’s population lives in places where air quality levels exceed WHO limits.
Which of our organs is mostly affected by air pollution and why?
Lungs and heart
There is now overwhelming evidence that air pollution results in serious harm not only to the lungs, but also to the heart. Here it increases the risk of heart attacks as arteries narrow and muscles weaken.

- Avoid exercising outdoors when pollution levels are high. ...
- Always avoid exercising near high-traffic areas. ...
- Use less energy in your home.
How primary and secondary pollutants are harmful for humans and environment?
Primary pollutants and secondary pollutants can be more dangerous. The first are those that are emitted directly from a source, which can be natural (volcanic eruptions or fires, for example) or of anthropogenic origin (carbon monoxide from vehicles) . Secondary pollutants, on the other hand, are not emitted directly.
How has pollution affected your health and well being how has it affected the well being of your family and the community?
