Air quality in Hyderabad, India, often exceeds the national ambient air quality standards, especially for particulate matter (PM), which, in 2010, averaged 82.2 ± 24.6, 96.2 ± 12.1, and 64.3 ± 21.2 μg/m(3) of PM10, at commercial, industrial, and residential monitoring stations, respectively, exceeding the national ambient standard of 60 μg/m(3). In 2005, following an ordinance passed by the Sup...

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 The study found that the problem of vehicular pollution in India was the result of a combination of outdated engine technology, poor fuel quality, defective transportation planning and bad maintenance of vehicles on road.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...

A traditional traffic signal control system is established based on vehicular delay, queue length, saturation and other indicators. However, due to the increasing severity of urban environmental pollution issues and the development of a resource-saving and environmentally friendly social philosophy, the development of low-carbon and energy-efficient urban transport is required. This paper first...

Exhaust emissions contribute greatly to air pollution, the social cost of which may occur as danger to human health, attracting huge medical expenses, causing absenteeism and hence loss of productivity. These are incentives to reduce exhaust emissions to the barest minimum. Two major cities in Ghana, Accra and Kumasi, are struck by vehicular traffic jams especially during rush-hours and are gra...

IEEE 1609.4 Standard for Wireless Access in Vehicular Environments (WAVE) has been proposed to enhance the performance of vehicular networks with multi-channel operations that allow for the coexistence of safety-related and non-safety related vehicular applications. At present, the evaluation of 1609.4-based Vehicular Ad Hoc Networks (VANETs) constitutes an open issue due to the lack of simulat...

We describe the use of discrete event simulation in modeling the curbside vehicular traffic at airports. The dynamic nature of vehicular traffic poses a challenge in developing a discrete event simulation model to represent roadway operations. We present our simulation methodology in modeling the new Austin-Bergstrom International Airport and address the use of simulation in the design as well ...

Changes in the concentration of different photosynthetic pigments (Chlorophyll and carotenoids) were determined in the leaves of six tree species exposed to air pollution due to vehicular emissions. The six tree species, which are all economically important because of their being fruit bearers, used for timber fodder and as road side trees on the basis of their air pollution tolerance index. Th...
