Nitric Oxide (NO) is regarded as a pollutant with multiple effects. These include visibility impairment, respiratory problems, declined crop yield, greenhouse effect and stratospheric ozone depletion. Together with SO2, NO is a major contributor to acid rain, ground-level ozone and photochemical smog. Of much recent concern for NOx (all oxides of nitrogen together) is its ability to form ground-level ozone with volatile organic compounds (VOC) in the presence of heat and sunlight. Consequently, the Environmental Protection Agency (EPA) is becoming stringent in terms of standards for NOx emissions to protect human health and the environment.
