“…Over the last few years, microfluidic devices have been shown to be capable of making analytical measurements to acceptable levels of accuracy and precision in a number of laboratory-based environmental applications (Marle and Greenway, 2005;Chen et al, 2006a;Richardson and Ternes, 2011;Jokerst et al, 2012). Integrated chips with separation and detection have been developed (and even used in the field) to measure streamwater P concentrations (Kang et al, 2001;Bowden et al, 2002a;Chen et al, 2006b).…”

Abstract. This paper introduces new insights into the hydrochemical functioning of lowland river systems using fieldbased spectrophotometric and electrode technologies. The streamwater concentrations of nitrogen species and phosphorus fractions were measured at hourly intervals on a continuous basis at two contrasting sites on tributaries of the River Thames -one draining a rural catchment, the River Enborne, and one draining a more urban system, The Cut. The measurements complement those from an existing network of multi-parameter water quality sondes maintained across the Thames catchment and weekly monitoring based on grab samples. The results of the sub-daily monitoring show that streamwater phosphorus concentrations display highly complex dynamics under storm conditions dependent on the antecedent catchment wetness, and that diurnal phosphorus and nitrogen cycles occur under low flow conditions. The diurnal patterns highlight the dominance of sewage inputs in controlling the streamwater phosphorus and nitrogen concentrations at low flows, even at a distance of 7 km from the nearest sewage treatment works in the rural River Enborne. The time of sample collection is important when judging water quality against ecological thresholds or standards. An exhaustion of the supply of phosphorus from diffuse and multiple septic tank sources during storm events was evident and load estimation was not improved by sub-daily monitoring beyond that achieved by daily sampling because of the eventual reduction in the phosphorus mass entering the stream during events. The results highlight the utility of sub-daily water quality measurements and the discussion considers the practicalities and challenges of in situ, sub-daily monitoring.

“…4 Most of these discharges have not been regulated yet, and the environmental fate of pharmaceuticals is not well understood. 5,6 Therefore, there is a growing interest for the disposal of such residues that could have potential negative effects on ecosystems. 7 Antibiotics, among all pharmaceuticals, are extensively used in treatment of diseases, and as such, their antimicrobial residues can have potentially adverse effects on humans.…”

“…8 In the last decades, antibiotic compounds have been considered as ''emerging contaminants'' due to their relatively high consumption and pseudo-persistence in the environment. 6,9 Conventional wastewater treatment approaches are usually ineffective at degrading pharmaceutical contaminants like antibiotics, because most such contaminants show poor solubility in water. 4 Therefore, different research groups have been focusing on other degradation processes, such as photochemical transformations and photocatalytic decompositions in order to increase removal efficiency.…”

“…It has been described as an emerging contaminant [1,2] due to its activity as an endocrine disruptor -20 even at low environmental concentrations, it affects the endocrine system of biological species. It has been banned for veterinary use in India due to links with declining vulture populations across the Indian subcontinent [3,4].…”
