“…Concentrations of paracetamol, diclofenac and trimethoprim were similar to those seen in other global estuaries, with mean concentrations less than 100 ng l -1 (Table 1). Whilst maximum concentrations of paracetamol were similar to those detected in rivers (Barbara Kasprzyk-Hordern et al 2008;Burns et al 2017), concentrations of diclofenac and trimethoprim were considerably lower (Hughes et al 2013;Nakada et al 2017). In the present study, water samples were collected at high tide, when concentrations would be expected to be lowest, so it is possible that these levels could be higher at other points in the tidal cycle (Yang et al 2016).…”

There is a lack of data on the occurrence of pharmaceuticals in estuaries worldwide, with little understanding of their temporal and spatial variations globally. Ibuprofen, paracetamol, diclofenac, trimethoprim and citalopram were measured in twelve estuaries in the UK. Initially, these compounds were monitored in the Humber Estuary, where samples were taken every two months over a twelve month period in order to assess their spatial and temporal variations. Ibuprofen was found at some of the highest concentrations ever measured in an estuary globally (18-6297ng l-1), with paracetamol also measured at relatively high concentrations (4-917 ng l-1) in comparison to the other compounds. In terms of spatial distribution, a pattern was observed where the highest concentrations were found at a site at which wastewater is discharged, whilst compound concentrations were often lower upstream and downstream of this site. The downstream profile of pharmaceuticals differed temporally with concentrations highest downstream when input from wastewater effluent was highest. Eleven further estuaries were sampled around the UK in order to put the occurrence of pharmaceuticals in the Humber Estuary into a wider context. Pharmaceutical concentrations in the other estuaries sampled were less than 210 ng l-1 but, again, ibuprofen and paracetamol were found at concentrations higher than other compounds, whereas diclofenac and citalopram were absent in many estuaries. The 2 Humber, which is the receiving environment for the sewage effluent of approximately 20% (13.6 million people) of the population of England, was observed to have the highest overall concentration of pharmaceuticals in contrast to the other estuaries sampled, thereby representing a worst case scenario for pharmaceutical pollution.

“…In a review of the worldwide occurrence of DEET in the aquatic environment, concentrations ranging from 40 to 3000 ng/L in various water bodies were reported ( Costanzo et al, 2007 ). Higher DEET concentrations were also found by Nakada et al (2017) in the Thames River (UK) (average 95 ng/L; max. 590 ng/L).…”

The River Thames and 15 of its major tributaries have been monitored at weekly intervals since March 2009. Monitored determinands include major nutrient fractions, anions, cations, metals, pH, alkalinity and chlorophyll a., and linked to mean 10 daily river flows at each site. This catchment-wide biogeochemical monitoring platform captures changes in the water quality of the Thames basin during a period of rapid change, related to increasing pressures (due to a rapidly growing human population, increasing water demand and climate change) and improvements in sewage treatment processes and agricultural practises. The platform provides the research community with a valuable data and modelling resource for furthering our understanding of pollution sources and dynamics, and interactions between water quality and aquatic ecology. Comparing 15 Thames Initiative data with previous (non-continuous) monitoring data sets from many common study sites, dating back to 1997, has shown that there have been major reductions is phosphorus concentrations at most sites, occurring at low river flow, and these are principally due to reduced loadings from sewage treatment works. This ongoing monitoring programme will provide the vital underpinning environmental data required to best manage this vital drinking water resource, which is key for the sustainability of the city of London and the wider UK economy.
