Photochemicals Emissions

A major concern for Comparative Analysis of the Feasibility of Alternative Locations for the Development of a Liquefied Natural Gas Precinct Jan (2009) report is that the airshed (air quality) both locally and regionally. LNG liquifiaction trains emit significant quantities of nitrogen oxide and volatile organics.

What are the dangers?

Photochemical smog can have an effect on the environment, on people’s health and even on various materials.

Chemicals such as nitrogen oxides, ozone and peroxyacetyl nitrate (PAN) can have harmful effects on plants. These substances can reduce or even stop growth in plants by reducing photosynthesis. Ozone, even in small quantities, can achieve this, but PAN is even more toxic to plants than ozone.

The biggest concern about photochemical smog is the effect it has on people’s health. The effects of the major primary and secondary pollutants in smog are given.

Health effects of pollutants involved in photochemical smog

Nitrogen oxides • can contribute to problems with heart and lungs
• links to decreased resistance to infection

Volatile organic compounds (VOCs) • eye irritation
• respirator problems
• some compounds are carcinogens

Ozone • coughing and wheezing
• eye irritation
• respiratory problems (particularly for conditions such as

Peroxyacetyl nitrate (PAN)
• eye irritation
• respiratory problems

According to the Wosley Parsons report (2008) it clearly states a piece of land will be required to accommodate up the 10 LNG trains. Redhand believes that this amount of trains, their emissions and pollution concentrations will well exceed the National Environmental Protection Measures. Again, Hands Off Country will be bringing you more information regarding the emissions as we piece our way through the Strategic Assessment Report Scoping document.
