In the Mszanka catchment area, similar fluctuations in
N-NH4+ were observed for grassy and
arable land. The lowest fluctuations in
N-NO2- and
N-NO3- were observed for forests. The
P-PO43- concentrations were highest in
permanent grassland. In addition, the highest TSS concentration in water
streams ranged between 5.43–25.35 mg·dm-3 in the
arable land (Table 2).
