Tritium in the Aquatic Environment

Tritium Modelling in Aquatic Systems

Models commonly used in tritium dose assessment are steady state specificactivity models based on the assumption of complete isotopic mixing with the stable element, and isotopic equilibrium between all environmental compartments (IAEA, 2010). These models may not be adapted to situations with fluctuating tritium levels in rivers, resulting from discontinuous radioactive discharges or accidenta...

Microplastics Pollution in the Aquatic Environment: Problems and Challenges

Microbiology of the Aquatic Environment

This is t~e fifth of several compilations of briefing papers on w~ter quahty prepared by the U.S. Geological Survey. Each bne:fing paper is prepared in a simple, nontechnical, easy-tounderstand manner. This U.S. Geological Survey Circular contains three papers on the microbiology of aquatic environment. Briefing papers are included on "The ecological role(s) of aquatic micro-organisms in lakes ...

13 Ethinyl oestradiol in the aquatic environment

This chapter describes the scientific evidence and regulatory debates concerning one of these oestrogens, ethinyloestradiol (EE2), an active ingredient in the birth control pill. First developed in 1938, it is released to the aquatic environment via wastewater treatment plants. Although it is now clear that wildlife species are exposed to and impacted by a cocktail of endocrine disrupting chemi...

Chemical sensor networks for the aquatic environment.

A recent commentary speaks to a broad range of potential applications for autonomous chemical sensor networks, including systems that monitor the state of the environment in real time.1 However, the authors of the commentary noted that existing sensor networks are “almost entirely restricted to transducers for detecting physical parameters such as temperature, pressure, light or movement”. They...
