The seasonal variability patterns of particulates varies among cities and sites, with Athens and Madrid presenting higher PM10 concentrations during the warm period and suggesting the larger relative contribution of secondary and natural particles during hot and dry days.
The spatial pattern of particulate organic mass over the southeastern U.S. is generally captured in the satellite-model product.
46 47 48 We classified distance to the nearest major road a priori as <50 m, 50 to <200 m, or ≥200 m, based on the observed pattern of particulate concentrations with increasing distance 47 48 49 and the distribution of roadway proximity in our sample.
The pattern of stratospheric particulate variations during the past decade "shows the fingerprint of volcanoes, with the right episodes showing up at the right time," says William Randel, an atmospheric scientist at the National Center for Atmospheric Research in Boulder.
The early development of lesions was first observed at 7 days, wherein the lesions surrounded the GO, and this was associated with a nonuniform, diffuse pattern of GO particulate deposition in the lung.
Aerosols scatter the light depending on their sizes, shapes, and compositions, so the scattering pattern of a particulate matter appears fairly greatest modulator of the ground reaching diffuse light.
Characterizing spatial patterns of airborne coarse particulate (PM10 2.5) mass and chemical components in three cities: the Multi-Ethnic Study of Atherosclerosis.
Mortality risk increased linearly with years of employment and was similar across job categories despite different current and historical patterns of exhaust-related particulate matter from diesel trucks, city and highway traffic, and loading dock operations.
No clear pattern was apparent in the concentrations of particulate organic carbon and particulate organic nitrogen (data not shown).
Altered patterns of gene expression mediate the effects of particulate matter (PM) on human health, but mechanisms through which PM modifies gene expression are largely undetermined.
