In the present study, a stationary stochastic ARMA/ARIMA [Autoregressive Moving (Integrated) Average] modelling approach has been adapted to forecast daily mean ambient air pollutants (O3, CO, NO and NO2) concentration at an urban traffic site (ITO) of Delhi, India. Suitable variance stabilizing...
Reservoir entrance environment is complicated and accepts different pollutants from various sources such as toxic, persistent, and bioaccumulative, and finally cause a permanent pressure on the environment. Sediment is the primary sink of heavy metals in aquatic ecosystems and has been recognized as an...

(1987) Application of SOS umu-test for the detection of genotoxic volatile chemicals and air pollutants. Environ. Mutag., 9, 171-176Ong, T.-M., Stewart, J., Wen, Y.-F. & Whong, W.-Z. (1987) Application of SOS umu-test for the detection of genotoxic volatile chemicals and air ...
Most of the AB 32 Scoping Plan measures will simultaneously reduce emissions of traditional criteria pollutants along with GHGs leading to a co-benefit of improved air quality in California. The present study quantifies the airborne particulate matter (PM2.5) co-benefits of AB 32 by comparing ...
