Even though oxygenated
phosphine fumigation is more complex and expensive than regular phosphine fumigation, Liu is optimistic that its benefits in terms of reduced treatment time and enhanced ability to control tolerant pests will more than compensate for the added costs and complexity.
The food ingested by the tadpoles in the hypoxic and oxygenated
water treatments was quantified in square centimeters of leaf mass.
water is probably not going to give anyone a sustained burst of energy, but it is harmless.
Motor Gasoline" includes conventional gasoline; all types of oxygenated
gasoline, including gasohol; and reformulated gasoline, but excludes aviation gasoline.
According to AP, various environmental and agricultural organizations have lobbied to retain the oxygenated
fuel mandate and DEQ director Stephanie Hallock said the state is considering the launch of alternative renewable fuel incentives before eliminating the region's winter fuel requirements.
The new research shows for the first time that subjecting sludge alternately to oxygenated
and oxygen-deprived conditions is highly effective at eliminating the hormones, he says.
Ronald Melnick, a toxicologist at the NIEHS Laboratory for Computational Biology and Risk Analysis, says Congress should recognize that oxygenated
fuels were less beneficial than expected, and that "for the most part, the impact on CO was overestimated in the initial models.
But the Oxygenated
Fuels Association said, "Despite its key contribution to the nation's enormously successful clean-burning gasoline program, MTBE has been unfairly singled out as a threat to groundwater.
In areas of the country where the National Ambient Air Quality Standards for carbon monoxide and ozone are routinely exceeded, the Clean Air Act requires that gasoline be oxygenated
to improve air quality.
specimens that had been conditioned in the oxygenated
Although the legislative effort to require alternative fuels has not been sustained, the use of "flexible" or alternative fuel formulations such as oxygenated
fuel mixtures has increased to meet strict CAFE (corporate average fleet economy) ratings.
Available data indicate that the extent to which oxygenated
fuels reduce winter air concentrations of carbon monoxide has been zero to about 10 percent, the committee said.
