Increased numbers of swine producers will be removing sludge from their anaerobic waste treatment lagoons in the next few years, due to sludge exceeding designed storage capacity. Information on availability of nitrogen (N) in the sludge is needed to improve application recommendations for crops. The objective of this study was to investigate possible effects of different companies and types of...

Detailed seasonal analyses of phytoplankton assemblages’ composition were performed on long-term datasets (20 years) two oligotrophic Mediterranean lagoons (Diana and Urbino), in order to test if community bloom events patterns rely a basis. Our results highlight similar between the lagoons, but different terms abundances, timing, magnitude occurrence Taxonomic Units, occurrence. Dominant diato...

Enteroviruses were isolated from influent and effluent wastewaters of two types of oxidation lagoons during an 18-month study. Isolations, performed by sewage concentration and direct assay, were low in number and did not follow a seasonal trend. The younger treatment system, using aeration and effluent chlorination, was more efficient at removing viruses than the aging, static complex.

In organic-enriched sedimentary systems, like many Mediterranean coastal lagoons, a detailed analysis of sediment grain size composition and partitioning within the muds is crucial to investigate sedimentological trends related to both hydrodynamic energy and basin morphology. In these systems, sediment dynamics are particularly important because the partitioning and transport of fine sediments...

Environmental releases of antibiotics from concentrated animal feeding operations (CAFOs) are of increasing regulatory concern. This study investigates the use and occurrence of antibiotics in dairy CAFOs and their potential transport into first-encountered groundwater. On two dairies we conducted four seasonal sampling campaigns, each across 13 animal production and waste management systems an...

Control methods are needed to abate NH losses from swine anaerobic lagoons to reduce the contribution of confined swine operations to air pollution. In a 15-mo meso-scale column study, we evaluated the effect of manure pretreatment on water quality, reduction of N losses, and sludge accumulation in swine lagoons using (i) enhanced solid-liquid separation with polymer (SS) and (ii) solid-liquid ...

In this study, we determined the technical characteristics and target species of some fishing gears, used in lagoon fisheries along Aegean Sea. The samplings were carried out five lagoons (Enez, Homa, Karina, Akköy Güllük) between 2014 2016. Technical plans gears drawn by MS-Visio programme with scale for gillnets, but no scales longlines. A total 10 type set nets which 8 trammel 2 3 longlines ...

in less than 150 words) The highly productive waters of Madagascar’s ‘Deep South’ are critical feeding grounds for the highly migratory species of the region, including seabirds and cetaceans. It is characterized by large coastal dunes, lagoons and coastal ponds, forming unique coastal habitats and wetlands; shallow benthic communities dominated by hard substrate communities, with small isolate...
