Usually <strong>use</strong>d in reference to amicrobial habitat.A reaction in which the atoms in an element lose electrons(<strong>of</strong>ten – but not limited to – to oxygen) See under ‘oxidativepeat losses’.Losses <strong>of</strong> peat resulting from the reaction <strong>of</strong> peat with oxygen(after drainage).An unstable gas in which three atoms <strong>of</strong> oxygen occur together.Ozone is a greenho<strong>use</strong> gas. In the atmosphere ozone occurs attwo different altitudes. Low altitude tropospheric ozone is a form<strong>of</strong> air pollution (part <strong>of</strong> smog) produced by the emissions fromcars <strong>and</strong> trucks. High in the atmosphere a thin layer <strong>of</strong>stratospheric ozone is naturally created by sunlight. This ozonelayer shields the earth from dangerous (cancer-causing)ultraviolet radiation from the sun. Several gases (notablychlor<strong>of</strong>luorocarbons, CFCs) speed the breakdown <strong>of</strong> ozone inthe ozone layer. While serious in its own right, this is largely adifferent problem from the problem <strong>of</strong> global warming. Abbreviatedas O 3.
