Since occupation is a major determinant of health, traffic police personnel face multiple occupational hazards. They are continuously exposed to vehicular emissions and work in a noisy and polluted environment. The objective of the present review is to explore the impact of occupational health hazards on the health of traffic police personnel. Published research papers on traffic police reporti...

Three dimensional simulations are carried out to estimate the effect of wind direction, wind speed and geometry on the flow and dispersion of vehicular pollutant in a street canyon. The pollutant sources are motor vehicles passing between the two buildings. Suitable emission factors for petrol and diesel vehicles at varying vehicle speed are used for the estimation of the rate of emission from ...

Detailed on-line measurements of city air quality are necessary to support compliance with air quality standards and emission strategy developments and to inform both policy makers and the general public in a timely manner. Current approaches to pollution monitoring, however, rely on very small numbers of stationary nodes. Providing detailed air quality information is a particularly hard challe...

Air pollution has become one of the main problems of cities. Among the sources of air pollution, vehicular traffic plays an important role. Planning for efficient management and control of the air pollution caused by vehicular traffic requires accurate information on spatio-temporal dispersion of the pollutions. This research studies 3D spatio-temporal dispersion of NOx pollution caused by vehi...

Source apportionment of total suspended particulate matter (TSPM) and associated heavy metals has been carried out for the city of Delhi using the Chemical Mass Balance Model, Version 8 (CMB8), as well as principle component analysis (PCA) of SPSS (Varimax Rotated Factor Matrix method) in coarseand fine-size mode. Urban particles were collected using a five-stage impactor at six sites in the wi...

The ambient air quality monitoring was carried during the May 2003 to April 2004 along the (NH-6) passing through Jalgaon city. The average concentration of SOx 64 microg/m3, NOx 58 microg/ m3, particulates (> 10 micro) 515 microg/m3 and respirable dust particulates 224 microg/m3 was reported at Prabhat during the study period (May 2003-April 2004). This location represents the major highway cr...

CSE blew the lid on smog and smogmakers in 1996 in its book Slow murder: The deadly story of vehicular pollution in India. The study found that the problem of vehicular pollution in India was the result of a combination of outdated engine technology, poor fuel quality, defective transportation planning and bad maintenance of vehicles on road. CSE exposed that the government was indulging in the...

The authors presented the contribution of gasoline vehicle exhaust to SOA formation in urban atmosphere. The manuscript indicated the importance of the vehicular gasoline compositions and clariïňĄed the principal problem of vehicular emissions for haze pollution in China. However, in your literature review, the authors missed some new ïňĄndings. E. g. Tang et al. (2015) illustrated the differen...

Tillandsia usneoides L. is an epiphytic bromeliad plant able to absorb water and nutrients directly from the air. For this reason this species was selected to carry out a monitoring study of air pollution in the metropolitan region of São Paulo, Brazil. Five consecutive transplantation experiments (8 weeks each) were performed in 10 sites of the city, submitted to different sources of air pollu...
