Concentrations of mercury and arsenic were monitored in water samples from the Záskalská water reservoir (Czech Republic) and its tributaries. The total mercury concentration in the reservoir ranged between 0.06-0.11 µg L-1 and in tributaries between 0.14-0.20 µg L-1. The effect of water erosion from abandoned cinnabar mine on mercury concentration in tributaries and reservoir was observed. The arsenic concentrations in water samples were between 0.21-0.54 µg L-1. The 98±10% of arsenic concentration in the water was determined as potentially bioavailable, whereas only 7-20% of the total mercury concentration in the water was determined as bioavailable using diffusive gradients in thin films technique.
