the effect of automobile pollution was determined on chlorophyll content of four different tree species viz. azadirachta indica l., conocarpus erectus l., guiacum officinale l.and eucalyptus sp. growing along the roads of the city.  significant changes in the level of chlorophyll “a”, chlorophyll “b” and total chlorophyll “a+b” were found in the leaves of four tree species (a. indica, c. erectu...

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...

Noise has many ill effects on living beings as well as non-living things. The adverse effects of noise may include noise induced hearing loss, sleep disruption, speech interference, reduction in human work efficiency and annoyance. In this paper an effort has been made to develop a fuzzy expert based model to study the annoyance among the road side dwellers, employees working in road side offic...

The study deals with the evaluation of the impact of heavy metal pollution on a Mediterranean natural ecosystem, and presents the results derived from a monitoring of heavy metals in different environmental matrixes (atmospheric dry depositions, suspended particulate matter (SPM) and stemflow of forest trees). Two sites in Castelporziano Presidential Estate (Rome), one internal and one near the...

transportation sector is one of the major contributors to noise in the urban areas. the traffic noise environment in balasore, a city of orissa, india in terms of standard noise indices, community response and community health effects are worked out in the present study. noise pollution is assessed in six different squares (road sections) of the town. it is inferred that the noise levels are mo...

This paper presents an integrated and adaptive problem-solving approach to control the on-road air quality by modeling the road infrastructure, managing traffic based on pollution level and generating recommendations for road users. The aim is to reduce vehicle emissions in the most polluted road segments and optimizing the pollution levels. For this we propose the use of historical and real ti...

Introduction: Heavy metals (HMs) accumulated in the road dust may be transferred to the surrounding land and water bodies and pose ecological risks. Hence, such pollution should be considered, especially in coastal roads. This study focuses on the HMs pollution of dust settled on the surface of coastal roads along the Persian Gulf in Bandar Abbas city. Materials and Methods: In this study, ro...
