widespread Routine Occurrence of pharmaceuticals in sewage effluent combined sewer overflows and receiving waters
Environmental Pollution, 2017Co-Authors: Stephen R Hughes, James R Ault, Alison E Ashcroft, Lee E BrownAbstract:Abstract Research addressing the Occurrence, fate and effects of pharmaceuticals in the aquatic environment has expanded rapidly over the past two decades, primarily due to the development of improved chemical analysis methods. Significant research gaps still remain, however, including a lack of longer term, repeated monitoring of rivers, determination of temporal and spatial changes in pharmaceutical concentrations, and inputs from sources other than wastewater treatment plants (WWTPs), such as combined sewer overflows (CSOs). In addressing these gaps it was found that the five pharmaceuticals studied were Routinely (51–94% of the time) present in effluents and receiving waters at concentrations ranging from single ng to μg L−1. Mean concentrations were in the tens to hundreds ng L−1 range and CSOs appear to be a significant source of pharmaceuticals to water courses in addition to WWTPs. Receiving water concentrations varied throughout the day although there were no pronounced peaks at particular times. Similarly, concentrations varied throughout the year although no consistent patterns were observed. No dissipation of the study compounds was found over a 5 km length of river despite no other known inputs to the river. In conclusion, pharmaceuticals are Routinely present in semi-rural and urban rivers and require management alongside more traditional pollutants.

Conversational Repair and Human Understanding: Conversational repair and human understanding: an introduction
Conversational Repair and Human Understanding, 2020Co-Authors: Makoto Hayashi, Geoffrey Raymond, Jack SidnellAbstract:Any serious effort to contend with the real time production and understanding of human actions in everyday interaction can scarcely avoid noting that they are characterized by the Routine Occurrence of troubles, “hitches,” misunderstandings, “errors,” and other infelicities. Indeed, these phenomena – and participants’ efforts to contend with them – are so ubiquitous that very few approaches within the human and social sciences have avoided commenting on, or contending with them, in some way. In many approaches within the social sciences, researchers looked past these phenomena altogether, treating them as epiphenomenal to the proper object of study (however that is defined) or as matters to be reduced, remedied, or otherwise overcome. More recently approaches from various disciplines have recognized their import in different ways, thereby raising the more nettlesome issue of just what is to be done with them or what can be done with them. Here, approaches vary considerably: some have simply incorporated these phenomena into the larger domain of human conduct being investigated (whether it is the psyche in psychology, ritual and culture in anthropology, or social structure in sociology), conflating a range of matters that are more profitably treated as distinct from one another. In many such cases, however, scholars interested in learning about the mind, self, language, society, and culture have treated these phenomena as special – as even more informative than other types of conduct. For these approaches the ubiquity of such troubles (and their management) makes them especially attractive since their Occurrence in the stream of conduct impacts on virtually every aspect of it. The perception that such troubles are special derives from a belief that they entail (or reveal) an authenticity obscured by more “practiced” behavior, or that they offer a window into the mind, or the depths of personhood, identity, and social relations, otherwise obscured by socialization, experience, or politeness. In these respects we might say that such approaches “exploit” such troubles insofar as they are not interested in them as such, but for how the apparently “unpracticed” character of such hitches, or the apparently revealing character of errors and the like, has
