Smoke alleviates adverse effects induced by stress on rice

Smoke and salinity are environmental hazards. Smoke produced DNA damage, inflammatory, and oxidative stress in humans while salinity reduced plant yield. However, smoke from plants is beneficial towards plant growth. In this study, smoke of two plants, Buhania varegata (1:1000 and 1:5000 dilutions (v/v)) and Cymbopogon jwarancusa (1:500 and 1:1000), were used to determine effects on different physiological and biochemical parameters in rice Basmati-385 (B-385) and Shaheen Basmati under different saline concentrations (control: 50, 100, and 150 mM). With increasing salinity, germination%, seedling growth, K⁺, Ca⁺, cell membrane stability, and total nitrogen and protein contents were decreased while Na⁺ content increased. However, seeds primed with different dilution of smoke significantly diminished the adverse effects of salinity and shown to produce positive responses in all of the above parameters. The most effective dilutions were 1:5000 for Buhania varegata and C-500 for Cymbopogon jwarancusa. It seems that priming with plant smoke solution is a potent stimulant for plant growth exerting a significant role in physiology and biochemistry of rice plants under saline condition.

Ex situ treatment of MTBE‐containing groundwater by a UV peroxide system

This article describes the design, implementation, and operating results for an ex situ ultraviolet/hydrogen peroxide (UVP) system to treat methyl tert‐butyl ether (MTBE) in extracted groundwater. The UVP modification was designed to reduce the operation and maintenance costs of an existing groundwater pump‐and‐treat treatment system that relied on air stripping and carbon adsorption. The UVP system is relatively inexpensive and can easily be scaled to cope with different groundwater extraction rates up to 80 gpm by adding UV lamps in series or in parallel at the higher groundwater extraction rates. The MTBE concentration in the effluent from the UVP system to the carbon vessels decreased from an average of 590 μg/L to approximately 2 μg/L on average over 33 months of operation of the UVP. Incorporation of this UVP modification as a second‐stage treatment to the groundwater pump‐and‐treat/soil vapor extraction system, after the air stripper and prior to the carbon vessels, significantly increased the usable life of the carbon (from two months previously to about two years after installation) and completely resolved the issue of frequent MTBE breakthroughs of the carbon that had plagued the remediation system since its inception. © 2006 Wiley Periodicals, Inc.     

Upstream Turbulence Effect on Pollution Dispersion

Experiments have been carried out to investigate turbulence at and above roof-level in an urban environment, and to predict the behaviour of street pollution from experiments using dye dispersion, for different roughness conditions and bed geometries. The flow in the boundary layer above an idealised urban environment has been simulated in a laboratory water flume. Comparisons have been made for the same model street canyon with and without the presence of upstream roughness. In the tests reported here, model street canyons were aligned perpendicular to the flow direction, and velocity measurements made within and above the model street canyons using a laser Doppler velocimeter (LDV). Flow visualisation techniques have also been used to confirm the gross flow features from streak images. Turbulence generated from the upstream roughness has a significant effect on the turbulence production and dispersion behaviour of the dye simulating pollution in street canyons.
