A study on the relation between the number of particulate matter particles in the air and the number

Ambient air pollution and daily outpatient visits for cardiac arrhythmia in Shanghai, China.


The authors revealed that PM2. This exposure, even at low concentration, can translocate into blood steam and remote organ to cause potential cumulative toxicity Bronchial asthma, chronic obstructive pulmonary disease and interstitial pneumonia were the most common ailments treated by area hospitals.

To limit the number of tests, we evaluated effect modification only when primary analyses indicated a main effect, and then only for the averaging period we judged to have the strongest association.

Long-term exposure to air pollution and markers of inflammation, coagulation, and endothelial activation: Design Observational cohort study.

In view of the above mentioned deleterious impacts of particulate matter, it is quite obvious that there is a need to investigate feasible and ecosustainable green technologies.

In this regard, the air cleansing capacity of urban trees presents an alternative means to foster an integrated approach to the sustainable management of urban ecosystems Rai, Increased levels of fine particles in the air as a result of anthropogenic particulate air pollution "is consistently and independently related to the most serious effects, including lung cancer [9] and other cardiopulmonary mortality.

Higher levels of spatially PM2. To prospectively examine the relation between an individual level assessment of long-term ambient air pollution exposures including PM2.

An update to the scientific statement from the American Heart Association.

A total of married registered nurses, agesresiding in 11 states, were originally enrolled; at least 10 participants now reside in each of the 48 continental states.

Reduced HRV often predict the likelihood of developing ventricular arrhythmias in post-MI and heart failure patients 93 However, unlike the results observed in short-term exposure studies, the reanalysis of ACS study demonstrated that the coarse particles PM10 were generally not significantly related to CV mortality Levels of premature death, chronic bronchitis, and cardiovascular disease are increasing at a rapid rate.

The study used a reliable indice, the thoracic aortic calcification TACto evaluate the subclinical atherosclerosis. Biological monitors are organisms that provide quantitative information on some aspects of the environment, including the presence of pollutants.

Larger particles are generally filtered in the nose and throat via cilia and mucus, but particulate matter smaller than about 10 micrometers, can settle in the bronchi and lungs and cause health problems. Short-term effects of air pollution on out-of-hospital cardiac arrest in Stockholm.

Inflammatory and oxidative stress responses of healthy young adults to changes in air quality during the Beijing Olympics. Lung cancer, cardiopulmonary mortality, and long-term exposure to fine particulate air pollution. There is also evidence to suggest that particle numbers are of greater significance than mass concentration in the determination of certain health effects.

Other gaseous pollutants e. This study will provide new and critically important information to understand the relation between ambient air pollution and cardiovascular morbidity and mortality. Regulation[ edit ] Due to the highly toxic health effects of particulate matter, most governments have created regulations both for the emissions allowed from certain types of pollution sources motor vehicles, industrial emissions etc.

Sun and his colleague demonstrated that exposure to environmentally relevant PM2. Some authors indicated that the associations between PM2.

Commitment to Privacy

Although the PM-related vascular dysfunction is documented in many articles, the results for BP response to acute PM exposure is inconsistent. Lichens, bryophytes, or mosses and certain conifers have recently been proven to be potent biomonitoring tools of air pollution Rai, Analysis of particulate mass concentrations, PM and PM 10, in terms of the relationships between different size fractions, emission sources, episodes of high particulate pollution, and contribution of windblown suspended particles.

Particulate Matter and Number Concentrations of Particles Larger than ┬Ám in the Urban Atmosphere of Jeddah, Saudi Arabia Article (PDF Available) in Aerosol and Air Quality Research.

H. Li et al. Figure 3. The relationship between concentrations of PM 10 and air temperature. Figure 4. The relationship between concentrations of PM and air temperature.

Table 1 Correlation coefficient between concentration of particulate. matter and a variety of meteorological factors. The particle number (or number of particles) of a thermodynamic system, conventionally indicated with the letter N, is the number of constituent particles in that system.

The particle number is a fundamental parameter in thermodynamics which is conjugate to the chemical potential. A study In conducted in the U.S. explored how fine particulate matter may be more harmful than coarse particulate matter.

The study was based on six different cities. They found that deaths and hospital visits that were caused by particulate matter in the air were primarily due fine particulate matter. The study will also assess the relation between air pollutants and cardiovascular disease using alternate exposure metrics focusing on ultrafine particle number counts, chemical composition of particles, and aldehydes.
