Article Synopsis
- PFOS is a common and resistant pollutant in water systems, but there’s limited data on its long-term effects on aquatic organisms.
- Toxicity tests were conducted on four species: midge (C. dilutus), water flea (C. dubia), amphipod (H. azteca), and zebrafish (D. rerio), revealing varying sensitivity to PFOS.
- C. dilutus was the most affected species, showing significant survival and growth impacts at very low PFOS levels, while C. dubia and H. azteca were much more tolerant to higher concentrations typically found in polluted environments.
The US Department of Defense (DOD) is developing insensitive munitions (IMs) that are resistant to unintended detonation to protect warfighters. To enable material life-cycle analysis for the IM, 1-methyl-3-nitro-1-nitroguanidine (MeNQ), ecotoxicological impacts assessment was required. A previous investigation of MeNQ exposures in Daphnia pulex revealed concentration-responsive decreases in reproduction relative to controls (0 mg/L) across a 174, 346, 709, 1385, and 2286 mg/L exposure range.
