Synergistic effect of crude oil plus dispersant on bacterial community in a louisiana salt marsh sediment

Effect of Crude Soybean Oil Sediment as a Substitute for Refined Soybean Oil in Broiler Diet

Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment gr...

Effects of Crude Oil, Dispersant, and Oil-Dispersant Mixtures on Human Fecal Microbiota in an In Vitro Culture System

The Deepwater Horizon oil spill of 2010 raised concerns that dispersant and dispersed oil, as well as crude oil itself, could contaminate shellfish and seafood habitats with hazardous residues that had potential implications for human health and the ecosystem. However, little is known about the effects of crude oil and dispersant on the human fecal microbiota. The aim of this research was to ev...

Comparative toxicity of oil, dispersant, and oil plus dispersant to several marine species.

Dispersants are a preapproved chemical response agent for oil spills off portions of the U.S. coastline, including the Texas-Louisiana coast. However, questions persist regarding potential environmental risks of dispersant applications in nearshore regions (within three nautical miles of the shoreline) that support dense populations of marine organisms and are prone to spills resulting from hum...

Patterns of Plant Community Development in a Created and a Natural Salt Marsh on the Gulf Coast of Louisiana, USA

The use of chlorate, nitrate, and perchlorate to promote crude oil mineralization in salt marsh sediments.

Due to the high volume of crude oil released by the Deepwater Horizon oil spill, the salt marshes along the gulf coast were contaminated with crude oil. Biodegradation of crude oil in salt marshes is primarily limited by oxygen availability due to the high organic carbon content of the soil, high flux rate of S(2-), and saturated conditions. Chlorate, nitrate, and perchlorate were evaluated for...
