Seasonal and spatial dynamics of enteric viruses in wastewater and in riverine and estuarine receiving waters
2018
International audience; Enteric viruses represent a global public health threat and are implicated in numerous foodborne andwaterborne disease outbreaks. Nonetheless, relatively little is known of their fate and stability in the environment. In this studywe used carefully validatedmethods tomonitor enteric viruses, namely adenovirus (AdV), JC polyomavirus (JCV), noroviruses (NoVs), sapovirus (SaV) and hepatitis A and E viruses (HAV and HEV) fromwastewater source to beaches and shellfish beds. Wastewater influent and effluent, surface water, sediment and shellfish samples were collected in the Conwy catchment (North Wales, UK) once a month for one year. High concentrations of AdV and JCV wer…
Modelling the impact of higher temperature on the phytoplankton of a boreal lake
2014
We linked the models PROTECH and MyLake to test potential impacts of climate-changeinduced warming on the phytoplankton community of Pyhäjärvi, a lake in southwest Finland. First, we calibrated the models for the present conditions, which revealed an apparent high significance of internal nutrient loading for Pyhäjärvi. We then estimated the effect of two climate change scenarios on lake water temperatures and ice cover duration with MyLake. Finally, we used those outputs to drive PROTECH to predict the resultant phytoplankton community. It was evident that cyanobacteria will grow significantly better in warmer water, especially in the summer. Even if phosphorus and nitrogen loads to the la…
