Information

Ecological parameter:  oxygen van Dam

Parameter group: habitat related parameters

Explanation:
Classification as oxygen indicator (measure of water pollution) following van Dam et al. (1994). Two different classifactions are provided: values modified by Coste (Lecointe et al., 1993) and values by van Dam et al. (1994).
