Life‐cycle studies with 2 marine species and bisphenol A: The mysid shrimp (<italic>Americamysis bahia</italic>) and sheepshead minnow (<italic>Cyprinodon variegatus</italic>).

Abstract: Bisphenol A (BPA) is a high production volume compound primarily used to produce epoxy resins and polycarbonate plastic. Exposure to low concentrations of BPA occurs in freshwater and marine systems, primarily from wastewater treatment plant discharges. The dataset for chronic toxicity of BPA to freshwater organisms includes studies on fish, amphibians, invertebrates, algae, and aquatic plants. To broaden the dataset, a 1.5‐generation test with sheepshead minnow (<italic>Cyprinodon variegatus</italic>) and a full life‐cycle test with mysid shrimp (<italic>Americamysis bahia</italic>) were conducted. Testing focused on apical endpoints of survival, growth and development, and reproduction. The respective no‐observed‐effect concentration (NOEC) and lowest‐observed‐effect concentration (LOEC) values of 170 and 370 µg/L for mysid and 66 and 130 μg/L for sheepshead were based on reduced fecundity. The hazardous concentrations for 5% of the species (HC5) values of 18 μg/L were calculated from species sensitivity distributions (SSDs) with freshwater‐only data and combined freshwater and marine data. Inclusion of marine data resulted in no apparent difference in SSD shape, <italic>R</italic>2 values for the distributions, or HC5 values. Upper‐bound 95th percentile concentrations of BPA measured in marine waters of North America and Europe (0.024 and 0.15 μg/L, respectively) are below the HC5 value of 18 μg/L. These results suggest that marine and freshwater species are of generally similar sensitivity and that chronic studies using a diverse set of species can be combined to assess the aquatic toxicity of BPA. <italic>Environ Toxicol Chem</italic> 2018;37:398–410. © 2017 The Authors.
