Abstract. Passive air samplers (PASs), which provide time-averaged concentrations of gaseous mercury over the timescale weeks to months, are promising for filling a gap in monitoring atmospheric worldwide. Their usefulness will depend on their ease use and robustness under field conditions, availability affordability, most notably, ability results acceptable precision accuracy. Here we describe...

Airborne pollen are important aeroallergens affecting human health. Local airborne compositions can pose health-risks for the sensitized population, but at present little is known about fine-scale composition patterns. The overall objective of this study to determine local variations in tree with passive samplers and identify surrounding landscape characteristics that drive them. In February–Ma...
