Air Pollution
This article gives us a detailed follow up about the relationship between particulate matter and respiratory function in elderly. Particulate matter is a type of solid in air, which is toxic in the form of smoke, dust or vapor. This matter are consists of microscopic particles which become deposited in the alveolar region, and can cause respiratory problems. Especially in the elderly Respiratory problems are specially seen in children, people with asthma, people with cardiac problems and also in elderly which very sensitive towards particulate matter.
To study and investigate the relation between particulate matter and respiratory function in elderly, researchers conducted a study in renal asylum. This study was conducted to measure peak expiratory flow rate (PEFR) and to compare estimated risks using PM10 or PM2.5. In order to study adverse effect on respiratory health researchers conducted a longitude study on people in dense area located close to traffic which is well developed individuals from private asylum for elderly. Researchers measured their (PEFR) in there panel surveys, each survey is of 4 weeks.
Next researchers took samples of ambient air concentrations of PM10 and PM2.5 and were placed on roof of 2 story asylum. Then the study was analyzed on the basis of combined data collected from participant and PM10 and PM2.5. The daily mean levels of PM10 and PM2.5 were 78 mg/m3 and 56 mg/m3 and the estimated PEFR changes were -0.39 1/min - 0.54 1/min. this data suggest that particulate matter have more adverse effect on sensitive individuals such as elderly. After the survey the result shows that elderly individuals were included out of those 34 subjected PEFR. The 24 hour mean PM10 and PM2.5 concentrations on average, the proportion of fine particles is 72% of PM10.The data from the study provide a unique opportunity to compare the impacts from two air partied indices on respiratory function.
