The Mussel Watch California pilot study on contaminants of emerging concern (CECs): Synthesis and next steps

Bioaccumulation of human pharmaceuticals in fish across habitats of a tidally influenced urban bayou

“…Carbamazepine, diphenhydramine, and erythromycin were detected in fish from the present study. These 3 pharmaceuticals, though not frequently detected (<20%) by Maruya et al, were also observed in mussels along the urban California coast [15]. Additionally, the antidepressant sertraline was frequently (64%) identified in marine mussels relative to other pharmaceuticals [13].…”

“…As noted above, available data for comparison are lacking as investigations of pharmaceutical bioaccumulation in urbanized coastal or estuarine areas are limited. However, Maruya et al [15] reported occurrence of select contaminants of emerging concern in marine mussels from urban coastal ecosystems in California, USA. Carbamazepine, diphenhydramine, and erythromycin were detected in fish from the present study.…”

“…Based on our previous observations of salinity differences with depth in Buffalo Bayou [11], samples of effluent, surface water (0.3 m from surface), and bottom water (0.3 m from sediment-water interface) and biological samples were collected during an extensive sampling event on 15 electrofishing locations within this area were determined by salinity influences on electrofishing effectiveness. Fish length and weight were measured on-site immediately after anesthetization using MS-222.…”

“…Bioaccumulation of human pharmaceuticals has been observed in aquatic organisms globally [12][13][14][15][16][17]. Physicochemical properties of pharmaceuticals and other contaminants of emerging concern dictate an advancement of historical approaches to define bioaccumulation, hazards, and risks [16].…”

Pharmaceutical bioaccumulation by periphyton and snails in an effluent-dependent stream during an extreme drought

“…Pharmaceuticals have been shown to accumulate in fish tissues (Brooks et al, 2005;Ramirez et al, 2007, http://dx.doi.org/10.1016/j.chemosphere.2014.08.044 0045-6535/Ó 2014 Elsevier Ltd.

Fick et al, 2010;Metcalfe et al, 2010;Schultz et al, 2010;Du et al, 2012) and other aquatic organisms, such as algae (Vannini et al, 2011), mussels (Bringolf et al, 2010;Contardo-Jara et al, 2011;Maruya et al, 2014) and sharks (Gelsleichter and Szabo, 2013) when these organisms are exposed to pharmaceuticals in laboratory settings or to wastewater effluent and surface waters receiving effluent discharges.…”
