Bioaccumulation and bioamplification of pharmaceuticals and endocrine disrupting compounds in caddisfly Silo nigricornis

Wastewater effluent pollution causes the presence of various pharmaceuticals (PhACs) and endocrine disrupting compounds (EDCs) in aquatic environments worldwide. Aside from their impact on aquatic biota, increased attention is recently given to researching the transfer of these chemicals from aquatic to terrestrial ecosystems. PhACs and EDCs can be transferred to terrestrial environments via food webs, but also with emergence of aquatic insects, which can bioaccumulate compounds during their aquatic life stage [1], [2]. Considering that the ecological and biological traits of aquatic organisms affect availability, exposure and bioaccumulation of PhACs and EDCs in organisms [3], [4], we examined bioaccumulation patterns in all life stages of the holometabolous caddisfly Silo nigricornis (Pictet, 1834). Furthermore, by calculating bioamplification factors (BAMFs) we aimed at determining trends in changing concentrations during different stages of metamorphosis. Samples were collected at wastewater impacted location with great abundance of the S. nigricornis. In total, 17 compounds were bioaccumulated in caddisfly tissues. Significant differences in concentrations between life stages were determined for seven compounds, all having highest values in adults compared to larvae and/or pupae. Concentration increase in adults is result of the metamorphosis solely, as these caddisflies do not feed as adults. Accordingly, BAMFs showed increase in concentrations during at least one stage of metamorphosis for 13 compounds. Moreover, for six compounds bioamplification was inferred (BAMFs ≥1) through both metamorphosis stages. All compounds with BAMFs over 1 have concentration in the tissues increased without additional exposure to the compounds. Increased body burden of PhACs and EDCs in adult caddisflies could greatly impact their riparian predators, such as spiders, birds and bats, which are consequently exposed to elevated concentrations of contaminants originating from aquatic pollution. Results of this research provide new insights on the behavior and fate of PhACs and EDCs on the aquaticterrestrial ecosystem boundary.
