Taints in meat - May 1999
The chlorophenols have disinfectant-like tastes, detectable in water in concentrations ranging from 0.04 parts per billion (ppb) for 2, 6-dichlorophenol to 30 ppb for pentachlorophenol (PCP). The chlorophenols are soluble in most organic solvents and are slightly soluble in water. Chlorocresols share the disinfectantchemical taste of the chlorophenols, and may have even lower taste threshold va...
متن کاملOcean Drilling Program Leg 204 Scientific Prospectus Drilling Gas Hydrates on Hydrate Ridge, Cascadia
During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...
متن کاملImpacts of gas drilling on human and animal health.
Environmental concerns surrounding drilling for gas are intense due to expansion of shale gas drilling operations. Controversy surrounding the impact of drilling on air and water quality has pitted industry and lease-holders against individuals and groups concerned with environmental protection and public health. Because animals often are exposed continually to air, soil, and groundwater and ha...
متن کاملNovel Desorber for Online Drilling Mud Gas Logging
This work presents the construction solution and experimental results of a novel desorber for online drilling mud gas logging. The traditional desorbers use mechanical mixing of the liquid to stimulate transfer of hydrocarbons to the gaseous phase that is further analyzed. The presented approach is based on transfer of hydrocarbons from the liquid to the gas bubbles flowing through it and furth...
متن کاملReal-time drilling mud gas monitoring for qualitative evaluation of hydrocarbon gas composition during deep sea drilling in the Nankai Trough Kumano Basin
BACKGROUND Integrated Ocean Drilling Program Expedition 338 was the second scientific expedition with D/V Chikyu during which riser drilling was conducted as part of the Nankai Trough Seismogenic Zone Experiment. Riser drilling enabled sampling and real-time monitoring of drilling mud gas with an onboard scientific drilling mud gas monitoring system ("SciGas"). A second, independent system was ...
