“…The reproduction LOEC of PFNA was approximately five times higher than that of PFOS. The fact that PFOS was found to be more toxic than PFNA in this study is not surprising, because this finding is similar to the results of other studies that have evaluated the toxicity of PFOS and other PFCs to aquatic organisms (Ji et al 2008;Ding et al 2012b). However, the reproduction NOEC and LOEC of PFNA/PFOS were all approximately five times higher than those of a single dose of PFNA or PFOS.…”

“…Ji et al (2008) also reported that the 48-hour EC50 of PFOS was 17.95 mg/L in Moina macrocopa, whereas Moina macrocopa was generally much more sensitive to PFOS than D. magna. The 48-hour EC50 of PFNA was 151 mg/L in D. magna, as reported by Ding et al (2012b). The 96-hour EC50 of PFOS was reported to be 78.13 mg/L, while that for 120 hours was 76.53 mg/L for zebrafish embryo (Ding et al 2012a).…”

“…However, for marine shrimp, Mysidopsis bahia, the 96-hour LC50 of PFOS for D. magna was reported to be 3.5 mg/L (Beach et al 2006), significantly lower than that for the freshwater organisms mentioned above. Different culture conditions and test procedures may partly account for the differences between the reported data in the same species (Ding et al 2012b).…”

In order to study toxicological effects of perfluorononanoic acid (PFNA), perfluorooctane sulfonate (PFOS), and their mixtures (PFNA/PFOS) on Daphnia magna (D. magna), a suite of comprehensive toxicity tests were conducted, including a 48-hour acute toxicity test, a 21-day chronic test, a feeding experiment, and a biomarker assay. D. magna was exposed to aqueous solutions of PFNA and PFOS (alone and in combination) at concentrations ranging from 0.008 to 5 mg/L. The survival, growth and reproduction of the D. magna were monitored over a 21-day life cycle. The biomarkers, including acetylcholinesterase (AChE), superoxide dismutase (SOD), and catalase (CAT) activities, were determined after seven days of exposure. PFOS was more toxic than PFNA based on the results of the acute toxicity test. The perfluorinated compounds (PFCs) inhibited both growth and reproduction of D. magna during the testing period. The ingestion rates as well as the biomarkers, including AChE, SOD, and CAT activities, were significantly inhibited by the PFCs in most cases. Moreover, the combined effects related to the growth and reproduction showed the antagonistic effects of PFCs.

“…According to the toxicity test of zooplankton, PFOA can significantly influence the population density of water flee (Sanderson et al 2003). PFOS may have a greater impact on Chironomid larvae than PFOA does, suggesting that PFOS may be associated with the oxygen stress response (MacDonald et al 2004) The EC 50 and NOEC values of six PFCAs in Daphnia were calculated, and they were inversely proportional to the length of carbon chains of PFAAs (Ding et al 2012). PFOS was approximately 2.5-fold more toxic to B. calyciflorus than PFOA and can affect the size of individuals and eggs and this toxicity is hereditary (Zhang et al 2013a).…”

Perfluoroalkyl acids (PFAAs) are emerging persistent organic pollutants that are globally distributed in the environment. In the present review, the occurrence of PFAAs and their behavior in aquatic ecosystem were summarized, and the health and ecological risk assessment and the multimedia fate simulation were investigated. PFAAs are most likely to exist in the aqueous phase, and PFAAs in atmosphere are also able to enter water bodies through diffusion and wet and dry deposition and eventually become widely distributed in various environmental media. The air-solid partition is considered to be one of the major factors in the long-distance transportation of the pollutants. The pKa values and organic carbon fraction of the sediment could influence the partition of PFAAs between water and sediment. Otherwise, PFAAs have teratogenic, mutagenic and other toxic effects and they could be accumulated by biota, and magnified through trophic level. The ecological and health risks of PFOA and PFOS were assessment. In order to explore the partition mechanism and reduce the uncertainty of the simulation of the transport, transformation and fate, the experimental methods on physicochemical properties of PFAAs should be developed. Moreover, further studies on toxicities of PFAAs are necessary for health and ecological risk assessment.

“…However, since many household products use PFCs as additives, it is difficult to calculate their amount of usage and the amounts released into the environment. Whereas the residual concentration of PFCs in the environment is small, at the ng/L (ppt) level or below, the effects on the ecosystem cannot be disregarded if the ecosystem then is exposed long-term to PFCs [6][7][8].…”

We surveyed the variation in perfluorinated compound (PFC) concentrations entering urban wastewater treatment plants and then designed an optimal PFCs treatment method based on a pilot test. The PFCs influent concentration was found to be affected by the types of industries and operating rate. The concentration of PFCs in the wastewater treatment effluent was slightly lower than that of the influent. Thus, PFCs had not been adequately removed by the existing biological treatments. The pilot test results showed that about 10% of PFCs was removed by coagulation and precipitation, and the ozone and chlorine test showed that few, if any, PFCs were removed regardless of the oxidant dose. The activated carbon adsorption test showed that the removal significantly increased with empty bed contact time, with about a 60% removal in five minutes and over 90% removal in over 15 minutes. Therefore, a more stable and higher PFCs removal would result from continuous oxidation processes, such as ozone and adsorption processes involving activated carbon, rather than a single biological treatment.
