The percentage of population living in these ter- ritories is approx. 33.2% and they occupy 9.5% of the total area of the Slovak Republic. These territories are usually linked to large urban and industrial areas. The territories belonging only to the level IV. of environmental quality are not a part of defined areas. There are approx. 233 000 inhabitants living on these territories. The following settle- ments together with their own urban areas belong to this group: Senica, Surany, Sahy, Zeliezovce, Levice, Nova Bafta, Lucenec, Svit and Presov.

They create a mosaic, divided by sig- nificant natural barriers that partly eliminate the negative impact. This region consists of the capital city of the SR area, that means Bratislava Districts I.-V. and the parts of near-by districts of Malacky, Pezinok and Senec. The number of inhabitants is 491 000, number of settlements is 17 and only Bratislava is a municipal industrial and administrative agglomeration. The endangered area of Bratislava region occupies 710 km2.

Soil Pollution According to the Soil Fertility Research Institute (VUPU) monitoring, the soil in Bratislava endan- gered region did not reach the level of heavily contaminated soil. Waste Management The principal method of waste treatment in Bratislava region is incineration in the city, incinera- tor that is going to be upgraded and reconstructed. The incineration residues (solid particular matter, clinker) are treated at the landfill site of the construction category III. near Pezinok. A serious problem of this area is the environmental impact of old unregistered landfill sites in various city districts. One of the most dangerous is gudrone landfill site in Devinska Nova Ves and also the waste from former CHZJD (Chemical works) in the natural bed in Mlynsky arm of the River Maly Dunaj near Vrakufia. The prob- lem of remediation of these landfill sites has not been solved yet. The largest waste producer in this area is Slovnaft a.s. Since the incinerator in this plant does not fulfill the demands of emission limits, the con- struction of the new incinerator with the capacity of 12 000 t.p.a. is prepared. The region occupies the area of Podunajska Highland with the part of Trnava and Podunajska Plain with the parts of Galanta and Sal'a districts. The axis of this region is broad flood plain of the River Vah. 46 The environmental impact is mostly from agriculture (food production), energy and chemical industries. In this endangered region, there are 162 000 inhabitants living in 20 settlements, out of which five are municipal. The region occupies the area of 384 km2.
