Four sampling routes were considered with ten sampling points (SP1-SP10) placed 2.0m away from the edge of the road. Priority parameters: SO 2 , NO x, CO were monitored. The results of SO 2 , NO x, CO were in the range of 0.02-0.09ppm, 0.009-0.039ppm, 1.79-51.38ppm respectively. The concentration of SO 2 was highest at SP 6 with value 0.5103ppm. Emission concentration for NO x was found to be highest at SP 6 where traffic congestion and traffic intersection is observed. The highest level obtained for the air pollution indicator of CO was at: SP 9, 6, 3and 10 due to traffic congestion and traffic intersection, where long waiting time for vehicles was observed. All the three monitored air pollutants when compared with AQI level (Air quality index) were in the range of: SO 2was from very poor to good, NO x-from good to very good, COvery good to moderate and moderate to poor in different locations. The study concludes that, it has become quite important to understand the role of mobile source emissions on air quality through well-designed studies. This information can provide important input for the formulation of effective air quality management strategies.

Geotextile materials have four main functional applications that include: separation, filtration, drainage, and reinforcement. The increased use of geotextiles may be attributed to various properties, such as puncture resistance, tensile strength, burst resistance, tenacity, and frictional resistance, permeability, to name a few. In the successful application of geotextiles, natural fibre-based geotextiles have little contribution: thus there is the need for improvement of their properties for them to adequately compete with synthetic geotextiles. There is also the need for awareness about other areas where geotextiles can function. One of such areas is the prevention of rapid moisture evaporation from the soil in agriculture. Indeed, polyolefin geotextiles have contributed meaningful innovation in the engineering field.
