Short And Long Term

In recent years great importance has been given to the adverse effects of particulate matter (PM) in health, and several epidemiological studies correlating the airborne particles with pulmonary injury have been carried out. The adverse effect of short- and long-term expositions to PM can, indeed, cause a variety of effects, from minor effects on the respiratory system to serious oncogenic effects that can lead to precocious death and are considered one of the top environmental public health concerns. Some cytogenetic techniques, as micronucleus assay, allow to detect chromosome breakage and loss by measuring the formation of micronuclei and proved to be a good tool in the evaluation of genotoxic damage induced by PM. Thus genotoxic effects can be evaluated by micronucleus test in order to identify a gradient of potential exposure and to assess environmental monitoring. However, cross investigations involving biomarkers of genotoxicity and electron microscopy PM-induced tracheal and lung damages in natural populations are not common.

Abstract Numerous studies have indicated that ambient particulate matter is closely associated with increased risk of cardiovascular disease, yet the evidence for its association with renal disease remains underrecognized. We aimed to estimate the association between long-term exposure to fine particulate matter, defined as particulate matter with an aerodynamic diameter less than or equal to 2.5 μm (PM2.5), and mortality from renal failure (RF) among participants in the Elderly Health Service Cohort in Hong Kong, China, from 1998 to 2010. PM2.5 concentration at the residential address of each participant was estimated based on a satellite-based spatiotemporal model. We used Cox proportional hazards regression to estimate risks of overall RF and cause-specific mortality associated with PM2.5. After excluding 5,373 subjects without information on residential address or relevant covariates, we included 61,447 participants in data analyses. We identified 443 RF deaths during the 10 years of follow-up. For an interquartile-range increase in PM2.5 concentration (3.22 μg/m3), hazard ratios for RF mortality were 1.23 (95% confidence interval: 1.06, 1.43) among all cohort participants and 1.42 (95% confidence interval: 1.16, 1.74) among patients with chronic kidney disease. Long-term exposure to atmospheric PM2.5 might be an important risk factor for RF mortality in the elderly, especially among persons with existing renal diseases.
