Results for dustfall monitoring are provided in Table 15.
As discussed in Section 2.3.1.2.2, deposition values based on dustfall data are expected to be the most reliable.
Storm water runoff models presently in use do not consider the physics of atmospheric dustfall.
Monitoring of Ni in dustfall samples was not conducted near any of the facilities.
Key words: atmospheric dustfall, air pollution, urban runoff, water quality, pollutant buildup, environmental modelling.
There have been only two exceedances of total dustfall at one site in Sault Ste.
The monitoring network also includes dustfall, sulphation plates and fluoride plates.
Christine Nicholl remembers being concerned about dustfall.
The violence of this ancient collapse has been scarcely masked by the three billion subsequent years of wind erosion and dustfall.
But it would take only one good dustfall - one good razorstorm - to fill the shafts almost to the surface. '
There were exceedances of air quality standards for total dustfall and fine particulate on the Ontario side (Bonney St. site near the steelworks).
As monitoring is usually continuous, results for individual dustfall samples from the same station can be summed for all samples collected over the period of a year.
Multi-element analyses and 34S-32S determinations of selected dustfall samples were performed as a possible means of defining airborne traJectories of the material collected.
Worlds of wild magnetism and perpetual dustfall, where the surfaces of the planets are changed by the forever-shifting magnetism of their erratic orbits!
So far, the dustfall monitoring results on the U.S. side show only traces of coarse particulate matter (coal, coke, kish, coal soot, iron oxide) normally associated with steel mill/works emissions.
Comparison of annual deposition estimated from TSP data with the more reliable annual deposition measured in dustfall samples indicates that TSP-based estimations are generally low by factors of 2–5.
Monthly monitoring of dustfall at Butler Park, located 1.3 km east of the Cominco-Trail facility, has been conducted by the B.C. Ministry of Environment (MOE) since 1971.
ABSTRACT The following final report describes investigations concerned with a sulfur inventory of central Alberta, particularly as it may be revealed by measurements of sulfur in rain, snow, hail, and dustfall.
The air quality monitoring for the ambient environment will consist of dustfall monitoring, whereas the air quality monitoring for the workplace will consist of control measures in the process plant and open pit mining areas.
It should be noted, by comparing values in the two tables for monitoring at similar distances from the sources, that annual deposition rates estimated from TSP data are in nearly all cases somewhat lower than those measured in dustfall samples.
While total dustfall increased in summer months, when the ground is bare and the weather dry, the amount of Pb in dustfall was highest in winter months when emission dispersion conditions are poor.
The invading, engineered flora unleashed by the second generation of colonists (tourists) has begun to recede, thwarted by the now constant, imperceptible dustfall of pure, original, profoundly Malvirian sand upon the falsely enriched soil of the Occupied Zone: suburbia.
Avondale North Borrow Area - Dustfall jars and hi-vol samplers were implemented and used over a two year period to monitor the environmental impact of dust from the Avondale borrow area just North of the Keele Valley Landfill in Maple, Ontario.
