Submicron aerosols (PM1) have more serious effect on the visibility, air quality, human health and climate change compared to coarse particles (particle size between 2.5 10 ?m). There is practical significance in understanding formation mechanisms sources of these particles. In this study, we conducted real-time measurements composition non-refractory submicron (NR-PM1) Guangzhou from 20 Octobe...
This paper is a preliminary attempt to assess the composition of pollutants in two different caldera lakes situated in the Indonesian Archipelago: Batur and Bratan. Both lakes are characterized by largely different physico-chemical regimes; Batur Lake is located in an area that is currently volcanically active, unlike Bratan Lake. The latter is much smaller and shallower than Batur Lake. The co...
