Sampling chamber for air mercury. Before air measurement, surface soil of about 5 cm thickness was removed, and a cylindrical chamber (20 cm diameter × 20 cm height) with a sampling hole (5 cm diameter) at the top was placed on the surface. After air sampling, about 5 g of soil was taken for mercury analysis.
