Abstract	CONCLUSIONS Environment: Ethylene is, due to its physical and chemical properties released mainly into the atmospheric compartment. About three quarters of atmospheric ethylene originates from natural sources, while one quarter is from anthropogenic sources. The main anthropogenic release is from burning of hydrocarbons and biomass. It has been well documented through relevant toxicity studies that the minute amounts measured in water implies little environmental hazard to the organisms in this compartment. In the terrestrial compartment, the vegetation has proven highly susceptible to this gas, probably through a mechanism related to the hormone function of ethylene in plants. Ethylene levels in urban areas have reached levels which inhibit growth of certain plant species. This is of concern both for decorative plants and agriculture in exposed areas. This is mainly due to incomplete burning of coal and petrol products in urban areas. The industrial emission is a minor contribution to total emissions and effects on vegetation are only expected close to production and processing plants. Human Health: Relevant studies have indicated a low toxicity of ethylene and no risk to human health has been identified neither from occupational exposure nor exposure of general public, either exposed directly or indirectly via the environment. However, metabolic studies in animals and man have revealed that ethylene is metabolised to ethylene oxide which is known to have carcinogenic and mutagenic effects. RECOMMENDATIONS No further testing of ethylene toxicity is recommended. It is recommended to do a closer monitoring of the environmental ethylene levels in urban and polluted regions with respect to its potential intoxication of vegetation, but this goes beyond the OECD HVP Chemical Programme.
