5. Identify one environmental problem caused by nitrogen dioxide, NO2. Suggest two things that
you can do to help reduce this problem.

High levels of nitrogen dioxide are also harmful to vegetation—damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.

1-We could use low-nitrogen fuels

2- We could also modify combustion conditions to generate less NOx. Flue gas treatment techniques, such as selective cata- lytic reduction (SCR) processes, can remove NOx
