Potential contamination (pollution) of surface waters with sediment, nutrients, and pesticides in agricultural runoff is an important water quality issue. Conservation tillage has been promoted and adopted by many row crop farmers because of its effectiveness in decreasing exposure to rainfall and reducing runoff and sediment loss. Vegetative filter strips (VFS), also known as buffer strips or ...

Water in many areas of Australia is scarce and of poor quality. In some areas high levels of treatment are required either due to contamination of waters or due to high salinity. Nanofiltration (NF) and low pressure RO membranes are well recognised technologies to treat waters of qualities ranging from low salinity surface water to high salinity seawater. In remote communities the operation of ...

IntroductionHuman activity in wilderness areas has the potential to affect aquatic ecosystems, including through introduction of microorganisms associated with fecal contamination. We examined microorganism contamination water sources (lake outlets, snowmelt streams) popular Absaroka Beartooth Wilderness United States. Although region is remote, increasing human visitation negatively quality, p...

We determined the antimicrobial resistance of Salmonella serovars from a total of 154 (44 chilling waters and 110 carcasses) samples collected from 22 poultry slaughterhouses. Standard culture techniques, Kauffmann-White slide agglutination and disc diffusion tests were used to isolate, and identify the serovars and to assess the antimicrobial activity, respectively. A total of 88 isolates belo...

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...

Contamination of recreational waters with cyanobacterial toxins continues to increase and presents a risk to animals and humans. Although cases of acute hepato- and neurotoxicoses in dogs following cyanotoxin exposure exist, no reports of skin-related reactions in dogs exist. A 5-year-old female spayed 34 kg Bracco Italiano was initially presented for rapid onset of severe pruritus and urticari...

The aim of this study was to evaluate the species distribution, antibiotic-resistance profile and presence of enterotoxin (SE) genes in staphylococci isolated from the Dilúvio stream in South Brazil. Eighty-eight staphylococci were identified, 93.18% were identified as coagulase-negative (CNS) and 6.82% coagulase-positive (CPS). Fourteen Staphylococcus species were detected and the most frequen...

Efforts to improve land-use practices to prevent contamination of surface waters with soil are limited by an inability to identify the primary sources of soil present in these waters. We evaluated the utility of fatty acid methyl ester (FAME) profiles of dry reference soils for multivariate statistical classification of soils collected from surface waters adjacent to agricultural production fie...

Heavy metals in southeast Kansas are frequently found in the shallow soil layers. Rainfall events in this region often generate overland flows which cause the release and migration of these chemicals into surface waters. The chemicals are then transported in surface waters to downstream locations and, as such, pose a threat to the quality of both fields along streams and surface and ground wate...
