What are the causes of air pollution?
There are a wide range of air pollution causes, from chemical or physical agents to biological agents that contaminate and change the atmosphere of the indoor or outdoor environment.1 Examples include common household gases like carbon monoxide, particulate matter, and ozone and pollutant gases such as nitrogen dioxide and sulphur dioxide.1,2

I’ve heard a lot about ‘ozone’, what is it?
Ground-level ozone causes smog in cities. It’s created when pollutants such as methane, nitrogen oxides and other pollutants from industry, traffic, waste and energy production, react with sunlight in what’s called a photochemical reaction.1
Why has pollution become such a big problem?
Since the Industrial Revolution, there has been a steady increase in the worldwide use of fossil fuels. This means carbon dioxide levels in the atmosphere have increased steadily since 1900.3
The chief source of mobile pollution in all industrialised countries of the world is without doubt the motor vehicle,4 powered by a four-stroke cycle (Otto cycle) engine fuel with gasoline.
Why use Otrivin Breathe Clean range?
If you are affected by air pollution, Otrivin Breathe Clean Saline range can help keep nature’s pollution filter (the nose) working.5,6 Your nose normally filters particles from the air you breathe by trapping them in the nasal mucus and hairs. They are then transported to the back of your throat and you swallow them, or you cough them out. But some types of pollution can affect this process and here’s where the system can break down. Some pollutants can cause inflammation in your airways, and you produce more mucus.7
Otrivin Breathe Clean Saline range works in the nose to clear away entrapped pollutants.
