It was determined that the content of heavy metals in sludge exceeds the maximum permissible limit for sludge pollution in Lithuania. According to cadmium amount, the pollution also exceeds maximum allowable soil pollution level. However, the sludge in the pond contains a rather large amount of oil-products.
