“…The U.S. Geological Survey (USGS) studied PAHs in three streams in Minnesota. Fluoranthene was in fact the chemical detected most frequently in this study, being found in at least 50% of the samples [18]. Rivers were characterised by DEHP concentrations in the range 100-500 ng·L -1 , but this did not therefore represent an exceedance of the limit values set out for surface waters.…”

Abstract. Negative and effectively "irreversible" changes in the environment have often been caused by one or more factors including the intensive development of new technologies, progressing urbanisation andabove all -insufficient knowledge of the properties and toxic effects of many chemicals used. Hundreds of non-natural compounds capable of exerting a negative effect on the natural environment have now been identified in it, including within the broad categories of pesticides, polychlorinated biphenyls and polycyclic aromatic hydrocarbons. Such new and emerging pollutants pose a serious threat to living organisms on account of their tendency to accumulate in certain parts of the environment. Furthermore, the substances in question may prove toxic and harmful to human beings and the environment even at low concentrations. Work described here thus had as its objective an analysis of the pollution of surface water in Poland in terms of content of organic compounds in general, and the aforementioned emerging organic pollutants in particular. Results confirm the presence in waters of such substances as phthalic esters, polybrominated diphenylethers, and organic tin compounds. Reference to average values for individual parameters in the cases of different rivers and lakes further show that, as of 2014-15, the various Polish surface waters researched were characterised by similar levels of pollution, other than in the case of naphthalene.

“…No other WWTPs discharge upstream from the sampling reach in the Grindstone River. Upstream from the South Fork Crow River sampling reach was one WWTP with a continuous discharge of 400 m 3 /day and three WWTPs with discharges of less than 340 m 3 /day that are intermittent controlled releases that are periodically discharged twice a year in the spring and fall (Lee et al ., ). In the sampling reach for the Redwood River, an industrial wastewater discharge from a wet corn milling operation with a daily discharge of 5,700 m 3 /day is between the upstream sampling location and the WWTP discharge (MPCA, ).…”

“…Upstream from the Redwood River sampling reach are four small WWTPs with controlled releases ranging from 151 to 640 m 3 /day for wet‐weather design flow (MPCA, 2004). The controlled release WWTPs in the South Fork Crow and Redwood River Basins released treated water from detention ponds during April and May of the 2007 study period (Lee et al ., ).…”

“…Width‐ and depth‐integrated water samples were collected and streamflow was measured six times from February through September 2007 to capture a variety of seasons and streamflow conditions (Lee et al ., ).

“…The WWTPs discharging to the rivers in this study varied in terms of population served, design flows, influent composition, and major industrial inputs (Table ). All three WWTPs use activated sludge for the secondary treatment (Lee et al ., ) and have continuous discharges. No other WWTPs discharge upstream from the sampling reach in the Grindstone River.…”

Alkylphenolic chemicals (APCs) and hormones were measured six times from February through October 2007 in three Minnesota streams receiving wastewater to identify spatial and temporal patterns in concentrations and in estrogen equivalency. Fish were collected once during the study to evaluate endpoints indicative of endocrine disruption. The most commonly detected APCs were 4‐tert‐octylphenol and 4‐nonylphenol and the most commonly detected hormones were estrone and androstenedione. Chemical concentrations were greatest for nonylphenol ethoxycarboxylates (NPECs) (5,000‐140,000 ng/l), followed by 4‐nonlylphenol and 4‐nonylphenolethoxylates (50‐880 ng/l), 4‐tert‐octylphenol and 4‐tert‐octylphenolethoxylates with concentrations as great as 130 ng/l, and hormones (0.1‐54 ng/l). Patterns in chemicals and estrogen equivalency indicated that wastewater effluent is a pathway of APCs and hormones to downstream locations in this study. However, upstream contributions can be equally or more important indicating alternative sources. This study indicates that aquatic organisms experience both spatially and temporally variable exposures in the number of compounds, total concentrations, and estrogenicity. This variability was evident in fish collected from the three rivers as no clear upstream to downstream pattern of endocrine disruption endpoints emerged.

The majority of previous research investigating the fate of endocrine-disrupting compounds has focused on single processes generally in controlled laboratory experiments, and limited studies have directly evaluated their fate and transport in rivers. This study evaluated the fate and transport of 4-nonylphenol, 17β-estradiol, and estrone in a 10-km reach of the Redwood River in southwestern Minnesota. The same parcel of water was sampled as it moved downstream, integrating chemical transformation and hydrologic processes. The conservative tracer bromide was used to track the parcel of water being sampled, and the change in mass of the target compounds relative to bromide was determined at two locations downstream from a wastewater treatment plant effluent outfall. In-stream attenuation coefficients (k(stream)) were calculated by assuming first-order kinetics (negative values correspond to attenuation, whereas positive values indicate production). Attenuation of 17β-estradiol (k(stream) = -3.2 ± 1.0 day(-1)) was attributed primarily due to sorption and biodegradation by the stream biofilm and bed sediments. Estrone (k(stream) = 0.6 ± 0.8 day(-1)) and 4-nonylphenol (k(stream) = 1.4 ± 1.9 day(-1)) were produced in the evaluated 10-km reach, likely due to biochemical transformation from parent compounds (17β-estradiol, 4-nonylphenolpolyethoxylates, and 4-nonyphenolpolyethoxycarboxylates). Despite attenuation, these compounds were transported kilometers downstream, and thus additive concentrations from multiple sources and transformation of parent compounds into degradates having estrogenic activity can explain their environmental persistence and widespread observations of biological disruption in surface waters.
