Mercury and radionuclides in sediments of the Kaštela bay (Croatia) : Evaluation of the sediment pollution history

Mercury and radionuclides (226-Ra, 238-U and 137-Cs) were measured in sediments of the Kaštela bay (Eastern Adriatic Coast), polluted with mercury by the chlor-alkali plant. From depth distribution of 238-U, 226-Ra and Hg it was revealed that sediment represents a mixture of natural sediment (rich in Hg) and ash (poor in Hg and rich in radionuclides) from coal used in factory power plant. Distribution of 137-Cs showed that sediment up to a depth of 50 cm was younger than 1986, meaning that dumping of the coal ash to the sea took place after this year.
