In 1847, the City Council of Pest opened a new central necropolis. In 1956, the cemetery was declared to be a National Pantheon and Graveyard. Nowadays, about half of the territory of the cemetery is settled, the individually or artistically remarkable tombs are protected, and the rest of the site is being re-designed as green area. In some parts of the cemetery, burials can still be carried out, but the major part of the graveyard is functioning as a public park.

The paper deals with the study upon the possibility to reduce migration of deposited pesticide wastes by using natural and waste sorption agents that would make a screen against plant protection means penetration into the hydrosphere. Sewage sludge from dairy treatment plant "Mlekovita" in Wysokie Mazowieckie as well as the same sludge with sawdust composted under natural conditions in Rudka Forestry Inspectorate was applied as natural sorption agents. Freundlich's and Langmuir's isotherms revealed that raw (no composting) sewage sludge showed better sorption features towards chloroorganic pesticides.
