organic nitrogen
Essential nutrient of the food supply of plants and the diets of animals. Animals obtain it in nitrogen-containing compounds, particularly aminoacids. Although the atmosphere is nearly 80% gaseous nitrogen, very few organisms have the ability to use it in this form. The higher plants normally obtain it from the soil after microorganisms have converted the nitrogen into ammonia or nitrates, which they can then absorb. This conversion of nitrogen, known as nitrogen fixation, is essential for the formation of amino acids which, in turn, are the building blocks of proteins. (Source: WRIGHT)

nitrogen oxides
Oxides formed and released in all common types of combustion; they are formed by the oxidation of atmospheric nitrogen at high temperatures. Introduced into the atmosphere from car exhausts, furnace stacks, incinerators, power stations and similar sources, the oxides include nitrous oxide, nitric oxide, nitrogen dioxide, nitrogen pentoxide and nitric acid. The oxides of nitrogen undergo many reactions in the atmosphere to form photochemical smog. (Source: GILP96)

catalytic converter
Catalytic converters are designed to clean up the exhaust fumes from petrol-driven vehicles, which are otherwise the major threat to air quality standards in congested urban streets and on motorways. Converters remove carbon monoxide, the unburned hydrocarbons and the oxides of nitrogen. These compounds are damaging to human health and the environment in a variety of ways. The converter is attached to the vehicle' s exhaust near the engine. Exhaust gases pass through the cellular ceramic substrate, a honeycomb-like filter. While compact, the intricate honeycomb structure provides a surface area of 23.000 square metres. This is coated with a thin layer of platinum, palladium and rhodium metals, which act as catalysts that simulate a reaction to changes in the chemical composition of the gases. Platinum and palladium convert hydrocarbons and carbon monoxide into carbon dioxide and water vapour. Rhodium changes nitrogen oxides and hydrocarbons into nitrogen and water, which are harmless.

degradation of natural resources
The result of the cumulative activities of farmers, households, and industries, all trying to improve their socio-economic well being. These activities tend to be counterproductive for several reasons. People may not completely understand the long-term consequences of their activities on the natural resource base. The most important ways in which human activity is interfering with the global ecosystem are: a) fossil fuel burning which may double the atmospheric carbon dioxide concentration by the middle of the next century, as well as further increasing the emissions of sulphur and nitrogen very significantly; b) expanding agriculture and forestry and the associated use of fertilizers (nitrogen and phosphorous) are significantly altering the natural circulation of these nutrients; c) increased exploitation of the freshwater system both for irrigation in agriculture and industry and for waste disposal.

acid deposition
A type of pollution which washes out of the atmosphere as dilute sulphuric and nitric acids. It tends to be a regional rather than a global phenomenon, linked to particular industrial activities and meteorological conditions. It includes rain, more than normally acidic snow, mist, sleet, fog, gas and dry particles. It upsets the balance of nature, disrupting ecosystems, and destroys forests and woodlands, plants and crops; kills aquatic life by altering the chemical balance of lakes and rivers and corrodes building materials and fabrics. The pollutants are caused principally by discharges from power station chimneys of sulphur dioxide and nitrogen oxides released by burning fossil fuels, coal and oil. (Source: WRIGHT)
