Bedeutung der Gesetzgebung zur Luftreinhaltung in der Prävention umweltbedingter Erkrankungen

Air pollution, for example from particulate matter, nitrogen oxides or ozone, is harmful to health. Short-term increases in air pollution can lead to exacerbation of existing lung diseases. Long-term air pollution contributes to the development of cardiorespiratory diseases. According to the European Environment Agency, 53,000 people prematurely died in Germany in 2019 due to particulate matter pollution. Air pollution control is a political task with great public health potential. In recent years, it has significantly contributed to improving air quality and thus health. In view of the new more stringent World Health Organization (WHO) air quality guidelines, the authorities and policy makers worldwide are now confronted with the question of adjusting air quality targets and setting standards. In Europe, the EU Directive on air quality standards is passed by the EU Parliament and the Council of the EU and is binding for air quality targets of member states. Member states can be brought to court for failure to achieve the targets. Therefore, there is a risk that achievable and less ambitious air pollution targets will be set. Even now, the EU guideline values are significantly higher than those in the USA or Switzerland. While “only” 11% of the EU population were exposed to levels above the current EU limit for PM10 in 2020, 71% of the population were exposed to hazardous levels of PM10 following the new recommendation by the WHO. Among the most important and successful air pollution control measures is the reduction of air pollutants at the source: emission control. Despite the energy crisis goals regarding air pollution control and climate protection must not be ignored. Importantly, health protection cannot be left to individuals. Health professionals have an important clinical role in advising sensitive patients on how to deal with short-term elevated levels of air pollutants but beyond that their advisory role in policy is very significant.
