Mobile substrate layers fill up coarse sediments and even pools with consequences for the habitat suitability of the interstices. Although sulfur dioxide and carbon dioxide occur in the air natu- rally, burning fossil fuels adds more of these chemicals to the air. What is more, the acid has deteriorated the general circumstances for the aquatic fauna due to washing aluminium out of granite-based soils.

Mobile substrate layers fill up coarse sediments and even pools with consequences for the habitat suitability of the interstices. Although sulfur dioxide and carbon dioxide occur in the air natu- rally, burning fossil fuels adds more of these chemicals to the air. What is more, the acid has deteriorated the general circumstances for the aquatic fauna due to washing aluminium out of granite-based soils.

Mobile substrate layers fill up coarse sediments and even pools with consequences for the habitat suitability of the interstices. Although sulfur dioxide and carbon dioxide occur in the air natu- rally, burning fossil fuels adds more of these chemicals to the air. What is more, the acid has deteriorated the general circumstances for the aquatic fauna due to washing aluminium out of granite-based soils.
