A field study was conducted to evaluate the impact of ambient ozone on mustard (Brassica campestris L. var. Kranti) plants grown under recommended and 1.5 times recommended NPK doses at a rural site of India using filtered (FCs) and non-filtered open top chambers (NFCs). Ambient mean O3 concentration varied from 41.65 to 54.2 ppb during the experiment.

In this paper, an analysis of data from continuous ambient air monitoring station in Hyderabad is reported to better understand daily and seasonal trends of particulates and chemistry of ozone pollution in the atmosphere.

Draft new EU legislation that would limit harmful vapour emissions from petrol pumps was proposed on 4 December by the European Commission. Petrol vapour contains benzene, which is known to cause cancer, and contributes to the formation of ground-level ozone, one of the air pollutants that is most damaging to human health and the environment and which also contributes to global climate change.

Ozone technology has been used for the past two decades or more. It is, however, only now that its use in wastewater treatment has been recognized.

Ozone technology has been used for the past two decades or more. It is, however, only now that its use in wastewater treatment has been recognized. The location of ozone use in wastewater treatment determines the goal of treatment. At the same time, ozone finds use in each stage of wastewater treatment.

Environmental air pollutants are inhaled as complex mixtures, but the long dominant focus of monitoring and research on individual pollutants has provided modest insight into pollutant interactions that may be important to health.
