Coastal Sediments
The release of particulate-phase trace metals due to sediment resuspension has been investigated by combining erosion chamber experiments that apply a range of shear stresses typically encountered in coastal environments with a shear stress record simulated by a hydrodynamic model. Two sites with contrasting sediment chemistry were investigated. Sediment particles enriched in silver, copper, an...
متن کاملAbundance and Distribution of Enteric Bacteria and Viruses in Coastal and Estuarine Sediments—a Review
The long term survival of fecal indicator organisms (FIOs) and human pathogenic microorganisms in sediments is important from a water quality, human health and ecological perspective. Typically, both bacteria and viruses strongly associate with particulate matter present in freshwater, estuarine and marine environments. This association tends to be stronger in finer textured sediments and is st...
متن کاملMicrobial manganese reduction by enrichment cultures from coastal marine sediments.
Manganese reduction was catalyzed by enrichment cultures of anaerobic bacteria obtained from coastal marine sediments. In the absence of oxygen, these enrichment cultures reduced manganates when grown on either lactate, succinate, or acetate in both sulfate-free and sulfate-containing artificial seawaters. Sodium azide as well as oxygen completely inhibited microbial manganese reduction by thes...
متن کاملPyrethroids in Southern California coastal sediments.
Little is known about pyrethroid fate and effects in estuarine and marine environments. In the present study, the extent and magnitude of pyrethroids in coastal embayments of the Southern California Bight (SCB), USA, were assessed. Using a stratified probabilistic design, 155 sediment samples were collected from four embayment habitats (estuaries, marinas, open bays, and ports) and analyzed for...
متن کاملAdsorption-Elution Techniques and Molecular Detection of Enteric Viruses from Water
Submit Manuscript | http://medcraveonline.com in drinking water. Faecal coliforms are used as indicators because of the assumption that the fate and transport of faecal coliforms reflect that of the waterborne pathogens [1]. However, accumulating evidence on waterborne disease outbreaks shows that absence of faecal coliform indicators does not entirely eliminate possibilities of the presence of...
