Cellular telephones have almost replaced conventional telephones for public use in Western European countries. Modern WAP telephones offer a mobile access to the internet from about everywhere at any time. This technique therefore appears to be very attractive for transferring up-to-date information about the environmental situation to the public, i.e. air and water quality measurements or weather conditions as well as forecasted values of these processes. On this account WAP services complete existing information sources for public use like the internet, videotext or print media. Location Based Services add a new dimension to these services. By automatically detecting the current location of the calling telephone the information offered to the user may thus be focussed to this location. Due to the relative small size of the telephone displays and the low resolution of these devices new concepts for designing such WAP-based environmental information services are essential.

Two environmental WAP services were realized on the basis of these concepts. The first one focuses on the topic of the air pollutant ozone and on meteorological parameters. The second service aims to inform the public about the up-to-date local gamma dosage rate of nuclear power plants.
