There are six pollutants in the world they are carbon monoxide, lead, nitrogen oxides, ground-level ozone, particle pollution and sulphur oxides. These gases can be toxic or poisonous to humans or animals. There are ways that people can prevent these gases from happing and leaking. Main things I would say if people are using equipment that give off these gases then they would have to turn it off because the fumes are dangerous and you will need to be hospitalized if inhaled.
There can be different things that if there’s gases or hazards there an be warning signs or danger signs telling people to stay back from the area effected.
Unauthorised people if they access the area without authorised access then they will be arrested for trespassing on the grounds at putting yourself in danger.
Carbon dioxide is the greenhouse gas most scientists consider the main air pollutant of the Earth’s atmosphere. Even though carbon dioxide is essential to support living organisms, it is also a dangerous air pollutant, generated mostly by human activities such as deforestation and the fossil fuel combustion.
The most harmful gas is NO2 .
Nitrogen dioxide is the most harmful of these compounds and is generated from the combustion of fuel engines and industry. It can damage the human heart and lungs and it reduces atmospheric visibility at high concentrations. Finally, it is a critical precursor to the formation of ground-level ozone.
