one of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic life. in the present study, impact of such factors as salinity, ph and do on flocculation of...

Dietary intake is the predominant route for human exposure to perfluorooctane sulfonic acid (PFOS). Single pollution events may thus affect human exposure if polluted ground and water is used to produce animal feed or food. In this study, a physiologically based pharmacokinetic (PBPK-) model is derived that describes the uptake of PFOS from contaminated feed by cows and its subsequent eliminati...

While there are many resources available to aid in the design and construction of most structural stormwater Best Management Practices (BMPs), there are few guides pertaining to their operation and maintenance. Historically, it seems as though “build-em” and walk has been common-place. However, increasing focus upon mass balances, numeric goal setting and Total Maximum Daily Loads (TMDLs), now ...

The disposal of spent refiactory materials has become a major problem for metals producers. The main issue surrounding refractory disposal is the elimination of the hazardous components of refractories, most commonly chrome-bearing materials and fluoride and cyanide in spent pot-liners. The various approaches to pollution prevention involve re-design to eliminate or significant reduction in was...

1. Introduction This paper presents the EU-MOP project (Elimination Units for Marine Oil Pollution) based on the design of an intelligent and autonomous robot system to respond to oil spills. The innovative factor of the EU-MOP project is focused on the functional autonomy and an information system for the tactical management and independent strategy during the operations scenario.
