摘要: Abstract Bedrock chemistry from three drill cores and fluxes of precipitation, throughfall runoff the 2015 water year were examined in forested catchments western Czech Republic. The coefficient alkalinity rocks at granitic (felsic) LYS catchment fall low chemical reactivity category. Rocks amphibolitic (mafic) NAZ have high serpentinitic (mostly ultramafic) PLB or even very reactivity. Streamwater reflected composition underlying bedrock lithologies, especially for magnesium, nickel chromium PLB, calcium, arsenic sulfur NAZ. incomplete neutralization acidic deposition had mostly negative correspondingly potentially toxic inorganic monomeric aluminum. Internal cycling magnesium calcium spruce canopy was influenced by substrate About half streamwater nitrogen left organic form.
