In contrast, transverse flow is formed with the installation of the ventilation system designed in this study, significantly decreasing the indoor air temperature (by 3 5 °C) and air pollution (to permissible air-quality limitation).
The permissible ambient air quality standards for selected air pollutants were for the first time enacted under the National Environmental (Ambient Air Quality) Regulations of 1994 [ 7].
It have been found that, owing to special physicochemical and structural-adsorption properties of 3H-CLI, it promotes formation of the palladium copper catalyst providing carbon monoxide oxidation at the steady-state mode down to CO concentrations lower than its maximum permissible concentration at air relative humidity varied within a wide range.
Although these standards have provided guidance that has been beneficial for Greek occupational health physicians, they have not been substantially changed since 1987 [action level, BLL ≥ 50 μg/dL; maximum acceptable level, BLL = 70 μg/dL; permissible airborne exposure limit, air lead (workplace) < 150 μg/m (8-hr average)].
Further, the U.S. EPA noted that children's health was addressed in the NAAQS rulemakings for ozone and particulate matter, which establish the maximum permissible concentrations of the most common air pollutants that other air regulations help meet (U.S. EPA 2000a).
"He'd say: 'More leg room in the driver's seat.' " Air travel being permissible for C.B.A. trips longer than 200 miles, I happened to run into Jackson and his team in December 1985 at the gate in Atlanta, changing planes on my way to Pensacola, Fla., to report a story on a comeback by the former Knicks center Marvin Webster.
Maximum permissible concentrations of radioisotopes in air and water can be deduced from the properties of the emitter and the dose limits.
The Court of Appeal reversed the judgment on grounds unrelated to Article 9, holding that open air pyres were permissible on a proper construction of the legislation.
Clearly, what may constitute permissible levels of asbestos in the air will add up to significant quantities on the ground.
Ms. Jackson's proposal — to reduce the permissible level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billion — is sensible, no matter what industry's defenders may claim.
The presence of excess of sodium causes most of the samples to be in the permissible-to-doubtful ranges and restricts air and water circulation in the soil during wet conditions (Collins and Jenkins 1996; Saleh et al. 1999).
