“…Mayflies are commonly used as biomonitors of contaminants in aquatic systems [31, 32]. Because this organism can accumulate high levels of sediment‐associated chemicals, our results confirm that mayfly larvae can effectively monitor PAHs and PCBs in sediment, although mayflies might not represent exposure and accumulation of organic contaminants in other invertebrate species.…”

Abstract-The distribution patterns of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were determined in four benthic invertebrate species of western Lake Erie, USA, to assess and compare the processes governing the exposure dynamics of these two classes of contaminants. Significant differences in the sum of 17 PAH compounds were observed among the four species, with mayflies containing the highest PAH body burden, followed by dreissenid mussels, amphipods, and crayfish. For PCBs, mayflies contained significantly higher concentrations of the sum of 39 PCB congeners than the other organisms, and dreissenids had higher levels than crayfish. No significant differences were found in the ⌺PCB levels between dreissenids and amphipods or between amphipods and crayfish. For PCBs, the relationship between biota-sediment accumulation factors (BSAFs) and log K ow followed a parabolic pattern indicative of selective bioaccumulation. In contrast, BSAFs for PAHs were inversely related to log K ow , suggesting that metabolism of the higher K ow compounds was occurring. These results support the conclusion that mayflies and dreissenids play major roles in the transfer of PAHs and PCBs to upper trophic levels, and they demonstrate that the exposure dynamics of PAHs and PCBs are different in the benthic components of aquatic food webs.

“…In their study area, concentrations of PCBs were greatest in mayflies from pool 4 near Lake Pepin, a 35-km long natural riverine lake that is an efficient sediment trap (14). Similar results were also obtained in the same area shortly after PCB use and disposal came under strict federal control (15).…”

“…Larval mayflies (Hexagenia limbata) accumulated benzo [a] pyrene, phenanthrene, and hexachlorobiphenyl when exposed to spiked sediments (22). Mobilization of sediment-associated pollutants by emergent insects has been verified in the field (20, [23][24][25][26], and spatial patterns of contamination in insects have been shown to correspond to those in sediments (27). Nevertheless, the linkage between emergent insects and contaminant levels in the animals that consume them remains largely unexplored.…”
