To investigate the possible relationship between airborne particulate matter and mortality, we developed regression models of daily mortality counts using meteorological covariates and measures of outdoor PM10. Our analyses included data from Cook County, Illinois, and Salt Lake County, Utah. We found no evidence that particulate matter < or = 10 microns (PM10) contributes to excess mortality i...

Although satellites provide reliable and repeated measurements on a global basis, particulate matter air quality information can be derived from satellites only when clouds are absent and when surface conditions are favorable. However, ground measurements provide particulate matter information irrespective of cloud cover and surface conditions. Therefore there could be a sampling bias when usin...

BACKGROUND We report on a novel approach to the analysis of suspended particulate data in a rural setting in southern Ontario. Analyses of suspended particulate matter and associated air quality standards have conventionally focussed on 24-hour mean levels of total suspended particulates (TSP) and particulate matter <10 microns, <2.5 microns and <1 micron in diameter (PM10, PM2.5, PM1, respecti...

Numerous studies have unmasked the deleterious effects of particulate matter less than 2.5 μm (PM2.5) on health. However, epidemiologic evidence focusing on the effects of PM2.5 on skin health remains limited. An important aspect of Asian dust (AD) in relationship to health is the amount of PM2.5 contained therein. Several studies have demonstrated that AD can aggravate skin symptoms. The curre...

Project Background The World Health Organization (WHO) recently announced that particulate matter (PM) now affects more people than any other pollutant. Here, we focus on PM less than 2.5 microns in diameter (PM2.5) as they pose a greater risk to human health via respiratory and cardiovascular diseases. We focus on Delhi, India for three main reasons: 1) according to the WHO it is the most poll...

INTRODUCTION Basic daily activities, such as walking and climbing stairs produce forces on the acetabular cup that results in shear forces throughout the contacting surface producing acetabular cup micromotion. Minimizing micromotion of the acetabular component is critical to the long term survival of total hip arthroplasty. A typical cementless acetabular component is coated with a porous surf...
