Marine aquaculture is expanding rapidly without reliable quantification of effluents. The present study focuses on understanding
the transport of dissolved wastes from aquaculture pens in near-coastal environments using the hydrodynamics code SUNTANS
(Stanford Unstructured Nonhydrostatic Terrain-following Adaptive Navier–Stokes Simulator), which employs unstructured grids
to compute flows in the coastal ocean at very high resolution. Simulations of a pollutant concentration field (in time and
space) as a function of the local environment (bathymetry), flow conditions (tides and wind-induced currents), and the location
of the pens were performed to study their effects on the evolution of the waste plume. The presence of the fish farm pens
cause partial blockage of the flow, leading to the deceleration of the approaching flow and formation of downstream wakes.
Results of both the near-field area (area within 10 to 20 pen diameters of the fish-pen site) as well as far-field behavior
of the pollutant field are presented. These detailed results highlight for the first time the importance of the wake vortex
dynamics on the evolution of the near-field plume as well as the rotation of the earth on the far-field plume. The results
provide an understanding of the impact of aquaculture fish-pens on coastal water quality. 相似文献

Seven pilot-scale partitioning gas tracer tests (PGTTs) were conducted to assess the accuracy and reproducibility of this method for measuring water in municipal solid waste landfills. Tests were conducted in the same location over a 12-month period, and measured moisture conditions ranged from possible dry waste to refuse with a moisture content of 24.7%. The final moisture content of 24.7% was in reasonable agreement with gravimetric measurements of excavated refuse, where the moisture content was 26.5+/-6.0 CI%. Laboratory tests were used to assess the utility of the PGTT for measuring water in small pores, water sorbed to solid surfaces, and the influence of dry waste on PGTTs. These experiments indicated that when refuse surfaces are not completely solvated with water, PGTTs may produce misleading results (negative estimates) of water saturation and moisture content. 相似文献

Carbonyls emitted from essential oils can affect the air quality when they are used in indoors, especially under poor ventilation conditions. Lavender, lemon, rose, rosemary, and tea tree oils were selected as typical and popular essential oils to investigate in terms of composition, thermal characteristics and fifteen carbonyl constituents. Based on thermogravimetric (TG) analysis, the activation energy was 7.6–8.3 kcal mol?1, the reaction order was in the range of 0.6–0.7 and the frequency factor was 360–2838 min?1. Formaldehyde, acetaldehyde, acetone, and propionaldehyde were the dominant carbonyl compounds, and their concentrations were 0.034–0.170 ppm. The emission factors of carbonyl compounds were 2.10–3.70 mg g?1, and acetone, propionaldehyde, acetaldehyde, and formaldehyde accounted for a high portion of the emission factor of carbonyl compounds in essential oil exhaust. Some unhealthy carbonyl species such as formaldehyde and valeraldehyde, were measured at low-temperature during the vaporization of essential oils, indicating a potential effect on indoor air quality and human health. 相似文献
