LIST OF ABBREVIATIONS


AF	Amplification Factor

AIDS acquired immunodeficiency disease syndrome

BAF Biological Amplification Factor

BCC basal cell carcinoma

CFC chlorofluorocarbon

CM cutaneous melanoma

CO carbon monoxide. A chemically-reactive trace gas that is believed to play an important role in controlling the oxidizing capacity of the free troposphere.

COS carbonyl sulfide. The most concentrated sulfur containing gas in the troposphere. COS is believed to be a source of background sulfate aerosols in the stratosphere.

CO2 carbon dioxide

CZCS coastal zone color scanner

DIC Dissolved inorganic carbon. Total concentration of dissolved inorganic carbon in water, expressed in units of grams carbon per liter

DMS dimethyl sulfide. The major volatile sulfur compound of biogenic origin emitted from the ocean into the atmosphere. DMS reacts in the troposphere to produce sulfate aerosols.

DNA deoxyribonucleic acid

DOC Dissolved organic carbon. Total concentration of dissolved organic substances in water, expressed in units of grams carbon per liter

DOM Dissolved organic matter. Total concentration of dissolved organic substances in water, usually expressed in units of grams carbon per liter

DU Dobson Unit (2.69 x 1019 molecules cm-2)

EC50 concentration resulting in 50% of specified effect

g DW Grams per dry weight

HCFC Hydrochlorofluorocarbon. The class of industrially produced compounds containing carbon, hydrogen, chlorine and fluorine. Can be used as chlorofluorocarbon substitutes.

HFC Hydrofluorocarbon. The class of industrially produced compounds containing carbon, hydrogen and fluorine. Can be used as chlorofluorocarbon substitutes

HIV human immunodeficiency virus

HSV herpes simplex virus

ISLSCP International Satellite Land Surface Climatology Project

IL-1,10 Interleukin -1, 10

NLOM Non living organic matter in the environment, e.g. litter, detritus

NMHC Non methane hydrocarbons. Volatile hydrocarbons emitted from terrestrial plants and marine phytoplankton that participate in various tropospheric chemical reactions

NMSC non-melanoma skin cancer

NO Nitric oxide. A highly reactive trace nitrogen species that participates in a variety of chemical reactions in the troposphere

NOx Nitrogen oxides. Reactive nitrogen-containing species, nitric oxide and nitrogen dioxide, that play an important role in tropospheric chemistry

N2O Nitrous oxide. An important greenhouse gas that also participates in stratospheric reactions that deplete ozone

PAM pulse amplitude modulation
