ter, an instantaneous dust sampler having a sampling duration of approximately onethird of a second. The collected dust sample was counted under a microscope and expressed as the number of particles per unit volume of air (particles per cubic centimeter). The earliest available konimeter dust data in Ontario date back to 1940. However, the ...
