Limits of 3, 7, 7, 45 and 100 microns should be exceeded over less than 5% of the length of ground track in the wavelength ranges 10 30 mm, 30 100 mm, 100 300 mm, 300 1000 mm and 1000 3000 mm respectively.
A flow duration curve provides the percentage of time the stream flow is exceeded over a historical period for a particular river basin (Vogel and Fennessey 1994).
The World Health Organization Air Quality PM2.5 Interim Target-1 (35 μg/m annual average) is exceeded over central and eastern Asia for 38% and for 50% of the population, respectively.
The WHO has set an interim target of 35 μg/m, which is exceeded over central and eastern Asia for 38%and50%0% of the population, respectively.
At the present time, shear base coefficients are established such that the probability that their value may be exceeded over a period of time does not exceed a small number.
From these analyses it is pointed out that the structure does not behave elastically in its existing condition even when subjected to the frequent design earthquake (81% probability of being exceeded over 50 years).
None of the traditional method is sufficient for the structure to survive basic design earthquake (10% probability of being exceeded over 50 years).
Earthquake hazard is measured in terms of the level of ground motion that has a certain probability of being exceeded over a given time period (McGuire 1995, 2008).
"To reduce one of the major health threats in our air, and to actually get to a standard where it hasn't been exceeded in over 10 years, is an achievement," he said.
The group also expressed concern that standards for fish and aquatic life, which are stricter than drinking water standards, in part because heavy metals accumulate in animal tissue over time, had been exceeded.
