“…Water quality is known to influence fish distribution and abundance, and the fresh waters of Puerto Rico have received substantial sediment, chemical and nutrient pollution from a variety of sources (Hazen, ; Hunter & Arbona, ; Warne, Webb & Larsen, ). However, recent surveys of aquatic contaminant concentrations in Puerto Rico stream and river habitats and biota revealed that the ecosystems were not severely polluted, with the exception of elevated concentrations of nickel, polychlorinated biphenyls (PCBs), and mercury in several fish species from agricultural and urban streams (Buttermore et al., ). Elevated PCB concentrations in American eel (0.019–0.031 ppm wet weight) were high enough in an urban Puerto Rico stream to pose a human health hazard.…”

The majority of American eel, Anguilla rostrata LeSueur, knowledge is derived from temperate regions in the United States and Canada, with little known from its tropical Caribbean distribution. Findings of original research on American eel distribution, abundance, population biology, habitat ecology and threats from the Caribbean island of Puerto Rico were synthesised. American eel were captured from 48 of 116 sites (41.4%) in 26 of 49 river basins (53.1%) during 2005–2016, and it was extirpated upstream of dams and migration barriers >3.0 m high (38.9% of habitat). Mean density and biomass were 438.9 fish/ha and 23.44 kg/ha, respectively. Upstream habitats favoured larger individuals, and females were larger than males. The swim‐bladder parasite Anguillicoloides crassus Kuwahara, Niimi & Hagaki was not found in 120 eels examined. Realised threats include dams and other migratory barriers, habitat loss and alteration and pollution; exotic species and commercial fishing are impending threats; and the least understood is climate change.

“…We deployed polyethylene and universal passive sampling devices (PE PSDs and uPSDs) at each of the 12 sites during six onemonth deployment periods between July 2012 and July 2014 to collect time-integrated water samples for organic contaminant analyses. PSDs estimate ecologically relevant exposure to contaminants (Heltsley et al, 2005), and the PE PSDs and uPSDs used here have been previously described by Luellen and Shea (2002), Hewitt et al (2006), Cope et al (2011) and Buttermore et al (2018). Both PSDs were placed inside a plastic mesh cage (5 mm openings) that allowed water to flow past while protecting the PSDs from debris.…”

“…In the lower Mississippi River of USA, a meticulous study of age-dated sediment cores revealed an upward trend in the hydrophobic organic compounds (except PAH) and trace element concentrations from the 1930's to 1970's followed by a decreasing trend till 2012 [41]. Although many large scale programs have been attempted to study the occurrence, distribution and trends of pesticides in the USA, these studies vary widely in terms of sample collection methods, analysis of sediment-cores and the species of biota sampled [31,42,43,44,45,46]. The major shortcoming of studies in the USA is the complexity in deriving an overall assessment of streambed pollution at a provincial or national scale owing to the differences in the design and duration of the studies [20].…”

Streambeds are among the important components of stream ecosystems and support several critical ecosystem services such as transformation of organic matter and nutrients and provide habitat for aquatic organisms. Increasing anthropogenic influence introduces multiple stressors to the stream networks resulting in pollution of streambeds, which in turn, could have detrimental effects on overall stream ecosystem health. However, there are gaps in the current understanding of the impacts of streambed pollution and the mitigation strategies lack holistic approach. In this review, we first present a global inventory to highlight the status of streambed pollution around the globe. Next, we synthesize the state-of-art knowledge of conventional and emerging forms of contaminants, their overall impacts on stream ecosystem functions, and finally present future directions to comprehend the problem of streambed pollution. We highlight that fine sediments and plastics (found especially in urban streambeds) are among the major physical pollutants of streambed pollution and the chemical pollutants generally comprise of hydrophobic compounds including various legacy contaminants such as polychlorinated biphenyl (PCB), dichlorodiphenyltrichloroethane (DDT), a wide range of pesticides and a variety of heavy metals. Further, in recent years, highly polar and hydrophilic emerging contaminants such as micro-plastics, pharmaceutical waste and personal care products have been identified in rivers around the world. We stress that the impacts of streambed pollution have been largely studied with discipline-driven perspectives amongst which the ecological impacts have received a lot of attention in the past. To present a comprehensive outlook, this review also synthesizes the hydrological, geomorphological and biochemical impacts of different forms of streambed pollutants. In the end, we endorse the positive and negative aspects of the current impact assessment methodologies and also highlight various physical, chemical and biological remediation measures that could be applied to alleviate streambed pollution.
