In view of the problems involved in remote sensing monitoring urban air quality, including low spatial resolution, only for a single pollutant, complex inversion algorithms, and difficultly obtaining parameter values, this study, new difference smog index (DSI) was developed, then comparison with normal haze index, MODIS aerosol optical depth products. The results show that DSI model developed ...

Fresh Water Rivers are one of the most important aquatic ecosystems in arid and semi-arid regions of Iran in point of biodiversity and drinking water views. Damghanroud River is one of these rivers at Semnan province that during past years has been threatened by drought and anthropogenic pollutions. This river supplies some parts of drinking water of Damghan city and some vicinity villages. The...

Expanding traditional time geography, this study examines personal exposure to air pollution and personal pollutant intake, and defines personal health danger zones by accounting for individual level space-time behavior. A 3D personal air pollution and health risk map is constructed to visualize individual space-time path, personal Air Quality Indexes (AQIs), and personal health danger zones. P...

Leachate pollution index (LPI) value can be used as a tool to assess the leachate pollution potential of landfill sites particularly at places where there is a high risk of leachate migration and pollution of groundwater and thus can help to take necessary decisions as deem fit. In this paper, leachate treatment efficiency was evaluated on the basis of LPI value of leachate before and after tre...

The lack a of standard approach for presenting contaminant remediation kinetics using the UV/H2O2 advanced oxidation process (AOP) for water treatment hampers efforts to cross-interpret results and apply literature data for the prediction of treatment efficiencies in new experimental settings. Properly weighted UV fluence rates can be used to define parameters for assessing the UV/H2O2 AOP that...
