Anthropogenic emissions to the atmosphere have increased the flux of nutrients, especially nitrogen, to the ocean, but they have also altered the acidity of aerosol, cloud water, and precipitation over much of the marine atmosphere. For nitrogen, acidity-d ...
Human viruses are ubiquitous contaminants in surface waters, where they can persist over extended periods of time. Among the factors governing their environmental persistence, the control (removal or inactivation) by microorganisms remains poorly understoo ...
Human viruses are widespread as contaminants in surface waters and represent a significant health risk. Viral pathogens can persist in aquatic ecosystems and cause infections via contaminated water or food. Among the different factors governing the environ ...
