Resumo: | The Almendares River constitutes the most important superficial stream in Cuban capital, that finishes in the Metropolitan Park of Havana, which is an entertaining centre. The objective of this work is to determine the presence of toxic inorganic pollutants in the Almendares River water. 10 samplings were carried out from June 2003 to May 2004 in 14 stations established along the last 10 km of the river and 3 tributaries. The quantification of nitrates, nitrites and ammonium was done by spectrophotometric methods The concentration of heavy metals in the dissolved and particulate phase was determined by atomic emission spectrometry. The total microbial charge was determined by epifluorescency. Were found high levels of ammonium and nitrites, as well as high values of Cd, Co, Ni and Pb. The total microbial charge were high in the 14 stations in spite of the presence of toxic metals.
