Noise: "In recent years, ongoing work by the academic and medical community has revealed the true health impacts of exposure to excessive environmental noise. Far from being a problem only for easily-dismissed “noise sensitive” people, an increasing body of academic research is showing that noise impacts all of us, whether we realise it or not. "

Pollution: "Aircraft release a cocktail of air pollutants, including NOx, sulphur, volatile organic compounds and particulate matter (soot and black carbon). Discussion about air pollution from airports has historically focused on nitrogen dioxide (NO2) pollution from increased road transport due to people driving to and from the airport. There has been some focus on NO2 emissions from aircraft during landing and take-off phases, but relatively little investigation into the role that plays in localised ozone formation at ground level, or indeed in the troposphere where it is known to be a climate forcer."
