Understanding the Ecological Consequences of Ubiquitous Contaminants of Emerging Concern in the Laurentian Great Lakes Watershed: A Continuum of Evidence from the Laboratory to the Environment

Exposure of Juvenile Lake Sturgeon to Contaminants of Emerging Concern (CECs), Including Polybrominated Diphenyl Ethers (PBDEs): Location Differences and Effects on Thyroid Hormones

“…Many CECs are unregulated and may pose threats to aquatic ecosystems. Previous research detected CECs in the Great Lakes basin at levels that can cause biological and ecological impacts in fish (Jorgenson et al 2018;Cipoletti et al 2019;Schoenfuss et al 2020). Changes in reproductive parameters, feminization of male fish, and altered liver function have been observed in wildcaught Largemouth Bass Micropterus salmoides and White Suckers Catostomus commersonii in correlation with the presence of CECs within in situ waters (Jorgenson et al 2018).…”

Additionally, laboratory studies of Fathead Minnows Pimephales promelas exposed to environmentally relevant mixtures of CECs have shown changes in fecundity, feminization of male fish, and high plasma vitellogenin levels (Schoenfuss et al 2020).…”
