Environmental biomonitoring conditions

Although variability is inherent in all environmental measurements, a variety of physical, chemical, and biological factors should be noted in compliance biomonitoring to enhance the consistency and de-fensibility of toxicity test results. These various parameters may affect the effluent toxicity to aquatic biota, and it is important that the investigator take them into account. Test conditions should mimic receiving water conditions, whenever feasible, to allow accurate assessment of the in-stream effect of an effluent. However, the use of upstream water for dilution should be avoided due to the potential variability in quality, or toxicity, over the testing period. 

Active biomonitoring can be carried out independently of the natural moss vegetation. Also F. antipyretica is relatively tolerant against alterations of environmental conditions, provided the water temperature is below 20°C.
