1The World Health Organization has classified diesel engine exhaust as carcinogenic, primarily due to its high concentration of fine particulate matter.
2Is the current regulatory framework for ambient particulate pollution sufficiently protective of vulnerable populations, such as children and the elderly?
3The study did not find a statistically significant correlation between coarse particulate levels and respiratory hospital admissions in the cohort.
4Ensure that all laboratory personnel wear appropriate respirators when handling any material that may generate airborne particulate contaminants.
5There is mounting epidemiological evidence that long-term exposure to even low levels of atmospheric particulate can accelerate cognitive decline in older adults.
