Researchers with the Swiss Federal Institute of Water Science and Technology wrote “Water-borne pharmaceuticals reduce phenotypic diversity and response capacity of natural phytoplankton communities” for PLOS One, published in March 2017. The scientists used Spectrum Labs’ Biotech CE dialysis tubing to “test for trans-generational effects of micropollutants on phytoplankton and the resulting consequences for community structure, trait variation, and functional properties”. The researchers found that high micropollutant levels significantly impacted the phytoplankton.

Abstract: Chemical micropollutants occur worldwide in the environment at low concentrations and in complex mixtures, and how they affect the ecology of natural systems is still uncertain. Dynamics of natural communities are driven by the interaction between individual organisms and their growth environment, which is mediated by the organisms’ expressed phenotypic traits. We tested whether exposure to a mixture of 12 pharmaceuticals and personal care products (PPCP) influences phenotypic trait diversity in lake phytoplankton communities and their ability to regulate biomass production to fit environmental changes (response capacity).
