The European Environment Agency has launched a photography competition, called ImaginAIR.
The theme of ImaginAIR is 'Photographing The Invisible', and the EEA want you to choose one of four themes, air and health, air and technology, air and nature, and air and cities.
Submissions open on 24 September, and the deadline is 4 October.
Competition organisers will select a shortlist of photo stories, which will be open to a public vote before winners are announced on 15 November.
A €500 prize will be awarded to the winner of each photo story category, and an additional €500 Youth Prize will be awarded to the winning photo story entry from a participant aged between 18 and 24.
The EEA will use some of the photographs in future publications on air quality, including web pages and reports.
ImaginAIR aims to raise awareness of the importance of air quality. Many of the air pollutants which cause acid rain have been reduced over the last few years, although several pollutants which seriously affect health are still a problem in Europe, particularly in cities.
Participants could choose to tell a story which considers the positive or negative aspects of air pollution. For example, the natural world absorbs a lot of air pollution, but natural processes can also be a source of poor air quality. Another example is that technology has a dual role – our consumption of the newest technology leads to pollution, but technological developments have also allowed us to monitor and filter
Other stories could tell how pollution has changed, show the health effects of air pollution, or depict an inspiring lifestyle which reduces air pollution. These are just a few ideas – indeed, the possibilities are as broad as the atmosphere.
