Plants exposed to air pollution show returnable and unreturnable biochemical and physiological alterations. So biochemical parameters can provide valuable information about physiological condition of plants that are subjected to air pollution. This study was performed to determine the effects of air pollutants on the amount of proline, protein, calcium and phosphorus in Medicago sativa and Phas...

Rapid urbanization and severe air quality deterioration in Pakistan have increased citizens’s concern towards air pollution. This study, conducted in November, 2016, aimed to develop relationship between degraded air quality and resident’s willingness to pay for improved air quality in city of Lahore, Pakistan through contingent valuation method to quantify an individual’s willingness to pay fo...

in recent decades, economic development and population growth in the world has led to the expansion of road networks. therefore the use of optimum methods for repairing and maintenance of these roads is considered as an important value. today one of the options in this regard, is the use of asphalt recycling technology. the present study which took place in the summer of 2015 in iran, lorestan ...

Modern studies in the field of environment science and engineering show that deterministic models struggle to capture the relationship between the concentration of atmospheric pollutants and their emission sources. The recent advances in statistical modeling based on machine learning approaches have emerged as solution to tackle these issues. It is a fact that, input variable type largely affec...
