Air Quality Introduction From world leaders at a global level, to neighbours in our community, air pollution has become one of our time’s greatest concerns coming high in the environmental agenda. Intricately connected to human health, welfare, and the natural environment, air pollution plays a significant role in our quality of life and is the driving force behind climate change. By measuring the concentration of pollutants in the air, advanced technology is used in order to monitor air pollution and determine the quality of the air we breathe. In Gibraltar, this is done through a formalised programme that makes use of three automatic monitoring stations that measure a variety of pollutants; and a passive monitoring network measuring nitrogen dioxide and volatile organic compounds with diffusion samplers. Operated with the objective of monitoring legislative compliance and developing future guidance on how to reduce impacts on humans and the natural environment, results logged at all stations are continuously examined and published in near real- time at www.gibraltarairquality.gi.

At this site, readings of benzene, carbon monoxide (CO), nitrogen dioxide (NO2), and sulphur dioxide (SO2) are taken. Benzene POLLUTANT BENZ Maximum hourly mean 27.1 µg m-3 Maximum running 8-hour mean 10 µg m-3 Maximum running 24-hour mean 5.4 µg m-3 Maximum daily mean 5.3 µg m-3 Data capture 73%* *lower than normal capture rate due to equipment failure.
