Dataset Supporting McClean and Hunter: 17a-Estradiol limits the impact of ibuprofen upon community respiration by streambed biofilms in a sub-urban stream. DOI: 10.1101/718924

Pharmaceuticals compounds such as the non-steroidal anti-inflammatory drug ibuprofen and the artificial estrogen 17a-estradiol are contaminants of emerging concern in freshwater systems. Globally, the use of these compounds is growing by around ~3 % per year, yet we know little about how interactions between different pharmaceuticals may affect aquatic ecosystems. Here we test how interactions between ibuprofen and 17a-estradiol affect the growth and community metabolism of streambed biofilms. Here we provide supporting data from contaminant exposure experimentsreporting how ibuprofen and estradiol affected biofilm biomass (ash free dry weigh), community respiration, net and gross primary production,
