Air pollution in Stuttgart ? NO 2 O3O3 PM 10
2
Stuttgart
3
NO 2 - Nitrogen dioxide Guideline values WHO 40 μg/m 3 annual mean 200 μg/m 3 1-hour mean Health effects causes inflammation of the airways at short-term concentrations (>200µg/m³) in asthmatic children increase symptoms of bronchitis with long-term exposure to NO 2 reduced lung function Source of NO 2 in the air burning of fossil fuels: motor vehicle exhaust
4
NO 2 annual average in Stuttgart 2004-2014
5
NO 2 in µg/m³–annual average 2014 German measuring stations
6
O 3 – Ozone (at ground level) Guideline values 100μg/m 3 annual mean Health effects It can cause breathing problems, trigger asthma, reduce lung function and cause lung disease Source of ground-level ozone created by chemical reactions with sunlight
7
O 3 –number of days >30°C – 1999-2012 Here: 120 μg/m 3 8-hour mean
8
PM 10 - Particulate matter (particulates less than 10 µm in diameter) Major components are: sulfate, nitrates, ammonia, sodium chloride, black carbon, mineral dust and water. Sources of particulates: natural processes: forest fires and wind erosion human activities: agricultural practices and car emissions also produced when chemicals from natural and human sources react
9
PM 10 - Particulate matter Health effects exposure to high concentrations: increased mortality or morbidity Chronic exposure to particles contributes to the risk of cardiovascular and respiratory diseases and lung cancer. Guideline values 20 μg/m 3 annual mean 50 μg/m 3 24-hour mean
10
PM 10 – particulates number of days with >50µgm³in 2014
11
PM 10 – particulate matter daily average
12
Summary 1.Air pollutants cause serious health effects 2.Guidelines by WHO protect us 3.Guidelines are broken frequently in Stuttgart 4.Very high average of particulates
