| Main sources of
polluation are the industrial plants that mainly pollute the environment with gases
containing sulphur, carbon, nitrogen and heavy metals. Most of the industrial plants were
built without taking into consideration the problem of polluation and waste, and
consequently they have no technology to manage the problem. Some of the greatest air
pollutants in the Republic of Macedonia are: the lead and zinc smelter in Veles, the steel
plant in Skopje, "Jugohrom" in Jegunovce and "Fenimak" in Kavadarci
with an estimation of overall emissions of about 10,000 tons SO2. Some the
chemical plants can also be mentioned as pollutants that pollute the air with specific
chemicals. Such are: the chemical plant OHIS in Skopje, the factory for fertilizers in
Zletovo and the oil refinery in the vicinity of Skopje. The power plant in Bitola and Oslomej are also air pollutants whose emission
of SO2 is about 2,000 mg/m3. The same is true for the central
heating enterprice in Skopje due to the fact that it uses fuel with great quantities of
sulphur. The newly built gas pipeline is expected to substitute this high polluting fuel.
In addition, the emissions of the automobiles in the highly populated areas contribute to
the high level of air pollution, especially if we bear in mind the fact that the average
age of vehicle is 11 years and most of them are without catalysts and use petrol with a
high level of lead (0.6 mg/l) and poor quality diesel (with 1% sulphur). The problem with
the emissions from vehicles is especially acute in Skopje where 40% of the population
lives.
