Chelation therapy with 2,3-dimercaptopropane-1-sulfonate (DMPS) has been used to treat acute and chronic heavy metal poisoning. It is thought to work by forming an insoluble complex with the metal that is firmly bound to intracellular sites.
In every Polish city, the ghettos were overcrowded. Jews were transferred from the other neighborhoods in the city, and in many cases from nearby villages, to housing there, while the non-Jewish inhabitants of the neighborhood were forced to move to another area. These transfers caused great overcrowding from the outset.
Ghettos across Eastern Europe varied in their size, scope and living conditions. The conditions in the ghettos were generally brutal. In Warsaw, the Jews comprising 30% of the city overall population were forced to live in 2.4% of the city's area, a density of 7.2 people per room.n the case of sealed ghettos, any Jew found leaving them could be shot. The Warsaw Ghetto, located in the heart of the city, was the largest ghetto in Nazi occupied Europe, with over 400,000 Jews crammed into an area of 1.3 square miles (3.4 km 2).
