“…Ankley et al (2005) found that fathead minnows exposed to 30 µg PFOS/L had ovary concentrations of 21.6 µg/g following exposure of 42 d. We report a similar result in that fish exposed to 44 µg PFOS/L exposure had ovary concentrations of 21.8 µg PFOS/g. Considering the variability in PFAS chemical analysis (Martin et al 2004; Lath et al 2019; Rewerts et al 2020, this issue), the PFOS concentrations measured in the present study are in close agreement with those of Ankley et al (2005). Unfortunately, the mass required for chemical analysis prevented us from having replicate data for other organs; and therefore, comparisons with published literature cannot be made with confidence, although PFOS liver concentrations per gram of tissue (wet wt) demonstrated a trend of increased PFOS sequestration in liver compared to gonads.…”

Per‐ and polyfluoroalkyl substances (PFAS) have emerged as contaminants of environmental concern following release from industrial practices and use of aqueous film–forming foam (AFFF). Of the identified PFAS in surface water samples from known AFFF release sites, perfluorooctanesulfonate (PFOS) and perfluorohexanesulfonic acid (PFHxS) are frequently detected. The focus of the present study was to determine the effects of PFOS and PFHxS to the native (and common) fathead minnow, Pimephales promelas, over critical life stages of reproduction and development. Two separate, 42‐d experiments were carried out using sexually mature fish, exposed to either PFOS or PFHxS. Measured exposure concentrations for PFOS and PFHxS were 0, 44, 88, 140, and 231 µg/L and 0, 150, 300, 600, and 1200 µg/L, respectively. At day 21 of the adult exposure, eggs were collected and reared for 21 d to determine the effects of PFOS or PFHxS on development, growth, and survival of larvae. The no‐observable‐effect concentration (NOEC) for PFOS was 44 µg/L, and the lowest‐observable‐effect concentration was 88 µg/L based on reduced growth in juvenile (F1) fish. Effects from PFOS exposures that did not follow a standard dose–response curve were reduced gonadosomatic index in adult males (at 44 µg/L) and reduced fecundity in females (at 140 µg/L). There was no toxicity on apical endpoints to report on adult or juvenile fish exposed to PFHxS up to 1200 µg/L. Importantly, we note that both PFOS and PFHxS accumulated in gonads and liver of adult fish following the respective exposures. The present study supports previous literature on PFOS toxicity and accumulation in fathead minnows but resulted in a lower NOEC than previously established for this species.

“…This likely is a function of shorter chains being more water soluble and less adsorbent [ 32 ]. In a recent study of adsorption on filter membranes and centrifuge tubes, other researchers found that polypropylene tubes were able to adsorb 32% to 42% of the PFOA in solution that came in contact with this material [ 33 ]. Although the exposure time and surface areas were much different than this study, these results are similar.…”

Perfluoroalkylated Substances (PFAS) Associated with Microplastics in a Lake Environment

The presence of both microplastics and per- and polyfluoroalkyl substances (PFAS) is ubiquitous in the environment. The ecological impacts associated with their presence are still poorly understood, however, these contaminants are extremely persistent. Although plastic in the environment can concentrate pollutants, factors such as the type of plastic and duration of environmental exposure as it relates to the degree of adsorption have received far less attention. To address these knowledge gaps, experiments were carried out that examined the interactions of PFAS and microplastics in the field and in a controlled environment. For field experiments, we measured the abundance of PFAS on different polymer types of microplastics that were deployed in a lake for 1 month and 3 months. Based on these results, a controlled experiment was conducted to assess the adsorption properties of microplastics in the absence of associated inorganic and organic matter. The adsorption of PFAS was much greater on the field-incubated plastic than what was observed in the laboratory with plastic and water alone, 24 to 259 times versus one-seventh to one-fourth times background levels. These results suggest that adsorption of PFAS by microplastics is greatly enhanced by the presence of inorganic and/or organic matter associated with these materials in the environment, and could present an environmental hazard for aquatic biota.

“…were weighed into polypropylene (PP) tubes and pre-equilibrated for 24 h with 7 mL of 0.5 mM CaCl 2 (AnalaR®) (Higgins and Luthy, 2006). The choice of containers were based on our investigations on their suitability (Lath et al, 2019). Next pH was measured using a smartCHEM-Lab™ pH meter and then adjusted with 1 M HCl (Scharlau) or 1 M NaOH (Univar).…”
