Do distinct water chemistry, reservoir age and disturbance make any difference on phosphatase activity?

Journal of Limnology, 2003
Alkaline phosphatase activity was assessed concomitantly with total phosphorus, orthophosphate and phosphomonoester concentrations in two meso-eutrophic reservoirs with distinct age and subjected to different kinds of environmental influence. Differences

A new concept for the ecotoxicological assessment of plastics under consideration of aging processes

Applied Research, Volume 3, Issue 2, April 2024.
Alternating stress scenario to plastics caused increasing ecotoxicity in algae growth inhibition tests with proceeding hydrolysis and ultraviolet stress times. The dissolved degradation products of polymers in the storage water of aging procedure and not microplastic particles caused the observed ecotoxicological effects.

Toxic effects of erythromycin, ciprofloxacin and sulfamethoxazole on photosynthetic apparatus in Selenastrum capricornutum

Ecotoxicology and Environmental Safety, 2011
The effects of three antibiotics (erythromycin, ciprofloxacin and sulfamethoxazole) on photosynthesis process of Selenastrum capricornutum were investigated by determining a battery of parameters including photosynthetic rate, chlorophyll fluorescence, Hill reaction, and ribulose-1.5-bisphosphate carboxylase activity, etc.
