![]() ![]() Similar studies are needed in conjunction with the ever-growing body of citizen science work to ensure that the limitations of these methods are fully understood.Īir pollution Biomonitoring Citizen science Lichens OPAL.Ĭopyright © 2013 Elsevier Ltd. We conclude that the simplified OPAL methodology can detect large contrasts in nitrogenous pollution, but it may not be able to detect more subtle changes in pollution exposure. ![]() The hypothesised changes were detected along strong pollution gradients, but not where the road source was relatively weak, or background pollution relatively high.

We hypothesised that the abundance of nitrophilic lichens would decrease with distance from the road, while that of nitrophobic lichens would increase. Find useful insights on Asia Air Surveys company details, tech stack, news alerts, competitors and more. We tested whether a recent citizen science survey (the OPAL Air Survey) could detect trends in lichen community composition over transects away from roads. However methodologies are often simplified to make them accessible to citizen scientists. It uses thermal desorption tubes to extract Volatile Organic Compounds (VOCs) from the air, concentrate them onto a single thermal desorption tube, and then analyze them using gas chromatography-mass. Citizen science is having increasing influence on environmental monitoring as its advantages are becoming recognised. AirSurvey utilizes the latest technology for the analysis of air.
