The enrichment of natural waters by nutrients from different sources has been associated with eutrophication in many Europe river basins. Materials accounting is a multidisciplinary approach to identify precisely the sources of pollution and to assess the most efficient preventive means to avoid the

The amounts of atmospheric depositions were measured by two types of bulk deposit-samplers (BDS). One of them was a commonly used dry-type BDS mounted with a conical polyethylene (PE) funnel on a PE-reservoir (d-BDS). The second BDS was a wet-type BDS which was devised to evaluate the nutrient loads

The Korissia lagoon is located in the southwest of Corfu Island, Greece. It is a shallow coastal ecosystem of great aesthetic and ecological importance, included in the Natura 2000 network of protected areas. The lagoon is connected to the sea by an artificial channel and its depth varies between 0.

The degradation of quantity and quality of lake waters nowadays forces scientists to develop advanced methods of studying and understanding lake ecosystems. These methods lead to models that have as an aim to describe in detail the chemical and biological processes that take place in the lake enviro

It is found that, at the same ML concentration, the specific ammonia utilization rates (nitrification rate) for the conventional BNR system are approximately 1.8 times higher than those found in the parallel MBR–BNR system, probably due to different selective pressures. In contrast, no differences i
