Reduction in Maximum Voluntary Ventilation of lungs of Sand Stone Quarry Workers: A Case study
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 3
Abstract
This study was designed to assess the impact of high particulate concentration on Maximum Voluntary Ventilation of lungs of sand stone quarry workers. The workers were engaged in different types of activities such as drilling, loading and dressing. These different working conditions had different concentrations of RSPM, leading to different exposure levels in workers. It was found that exposure duration and exposure concentrations were the main factors responsible for damage to the respiratory tracts of the workers. The particles were deposited at various areas of the respiratory system and affect the Maximum Voluntary Ventilation of lungs . It was also revealed from the study that most of the workers suffered from silicosis if the exposure duration was more than 20 years
