Description
  • Sixty-three brooks, in the frontier region between Bavaria and Czech Republic, subject to different human impacts were investigated. Basic hydrochemistry, 79 elements and some organic compounds (PAK, aromates, halogen-CH ) were evaluated. A total number of 256 species of algae and cyanobacteria was registered with 35-40 species per site. By using multivariate methods, acidification proved to have the strongest influence on the composition of phytobenthos (29%), followed by industrial sewage (27%), domestic sewage (19%), agriculture (18%). Traffic influence to phytobenthos composition was insignificant. From the natural influences quality of bottom was the most prominent, then presence of fishes and velocity of the stream. Algal growth potential declines in the following sequence: domestic sewage > agriculture > not-influenced > traffic > acidification

  • Bylo studováno šedesát tři potoků příhraniční oblasti mezi Bavorskem a Českou republikou, s různým ovlivněním člověkem. Základní hydrochemie, 79 prvků a některé organické látky (PAK, aromáty, halogenované uhlovodíky) byly stanoveny. Bylo nalezeno celkem 256 druhů sinic a řas, 35-40 druhů/lokalitu. S použitím multivariačních metod se acidifikace prokázala jako nejsilnější vliv na složení fytobentosu (29%), následují průmyslové odpady (27%), domácí odpady (19%), zemědělství (18%). Vliv dopravy na fytobentos byl neprůkazný. Z přírodních vlivů nejsilnější byl typ dna, další přítomnost ryb, a rychlost toku. Řasový růstový potenciál klesal v pořadí: domácí splašky > zemědělství > neovlivněné > doprava > acidifikace (cs)
