Introduction: Street vendors are the most dominant occupation in urban and rural areas. Street vendors are exposed to several environmental pollution. They inhale toxic compounds such as carbon monoxide, carbon dioxide, ozone, nitrogen dioxide and other volatile organic chemicals. This is due to emission from vehicles and traffic. The aim of the study is to assess lung function on street vendors of the Chennai region. Materials and Methods: The study is done among street vendors in chennai region. The study included 50 people where 25 people are from the exposed group and 25 people are from the normal group. It was conducted by using a computerised spirometer. The total air capacity of the lung. The data was collected and entered in SPSS software. The results were obtained by doing an independent sample T test. Result and Discussion: Parameters like FVC, FEV1, PEF, FEV1/FVC were used to assess the lung function. It was observed that there is a decline in pulmonary functions parameters of the street vendors and it was not statistically significant . Conclusion: Thus the effect of pollution by the vehicles may be responsible for the pulmonary function impairment on street vendors affecting their lungs and other organs. This can be prevented by using face masks, lifestyle modification etc.

“…In addition, Zhang Yajing of the Tianjin University, also through the analysis of the road on both sides of the air quality index (AQI), and the difference of authority of air quality index of pollutant concentration and the road distance relationship, in order to verify the motor vehicle exhaust is the main pollution source of [2] City, on the road on both sides of the air pollution index and air quality monitoring sites released by the API index in the study, found the road on both sides of the AQI index was significantly higher than the published AQI index even reached 3 -5 times the difference. The main components of vehicle exhaust are: carbon monoxide, polycyclic aromatic hydrocarbons, lead compounds, toxic particles such as respirable particles less than 10mm in diameter, which can cause chronic bronchitis, emphysema, lung cancer and other diseases [3,4,5]. Therefore, it is the purpose of this paper that how to reasonably plan the path, so that pedestrians can effectively avoid the serious pollution of motor vehicle exhaust, and reduce the amount of pollutants collected in the air.…”

The main pollution source of urban air quality is vehicle exhaust pollution, in which a variety of toxic and harmful substances seriously affect the health. In this paper, a pedestrian path planning algorithm based on low exhaust gas intake is proposed. The vehicle exhaust collection device is used to collect and analyze the concentration of harmful gases on the road edge, and calculate the air quality index of each section by AQI calculation method. In order to reduce the intake of harmful gas in the existing road network model, the route planning of the minimum harmful gas intake from the starting point to the destination node is given by using the A* search algorithm. Experiments show that the algorithm can effectively avoid the large traffic flow and serious air pollution section.

Introduction: Street vendors work daily selling their goods on the sidewalks along the streets and seldom have breaks .They are considered the most working groups that are at the highest risk of exposure to air pollution as they usually work for long hours and are continuously exposed to inevitable: adverse weather conditions, atmospheric and road dust, vehicular emissions and air pollutants from industrial and other sources, resulting in a wide range of adverse respiratory health effects. Aim of work: To assess the prevalence of respiratory symptoms and the effect of outdoor work environment on pulmonary functions measurements among female street food vendors in Mansoura city. Materials and methods: A descriptive cross-sectional study was carried upon (152) stationary female street food vendors in Mansoura city during the period from August to December 2017. The sample size was calculated using MedCalc program version18. Data was collected using a questionnaire included sociodemographic characteristics, occupational and medical histories focusing on the respiratory symptoms in the last 12 months. Clinical examination and measurement of the pulmonary functions were done. Results: There was a high prevalence of respiratory symptoms among street food vendors in the last 12 months (86.2%). The mean observed values of FEV 1 and FVC were statistically significantly lower than their predictive values and the mean observed values of FEV 1 /FVC % were statistically significantly higher than their predictive values. Conclusion: Street vendors are at high risk of respiratory symptoms and impaired pulmonary functions. Bronchial asthma ranked the first disorder for the respiratory system (18.4%) among street food vendors followed by chronic bronchitis (7.9%).
