Numeorus analytical methods have been developed for determination of micronutrients, heavy metals and trace elements in soil. However, rapid and easy-to-perform methods are still needed for chemical composition analysis of soil that would be based on simultaneous extraction of multiple elements. Furthermore, it would be beneficial if element concentration in soil using these methods were correlated with its concentration in plants. The aim of the study was to determine the interdependency between soil concentration of: Al, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, Ti, V and Zn extracted using 0.03 M CH3COOH or 1 M HCl and its content in spinach leaves and lettuce heads. In reference to Al, B, Ba, Cd, Mn, Ni and Zn level in spinach as well as Al, B, Ba, Cd, Cr, Fe, Li and Ti accumulation in lettuce, higher values of correlation coefficients were calculated for soil and plant content of these elements after extraction with 0.03 M CH3COOH than 1 M HCl. In the case of: Cr, Cu, Fe, Li and Sr in spinach as well as Ni and Pb in lettuce, higher values of this parameter were found for 1 M HCl soil extraction when compared with the other tested method. No significant relation was found between Pb and Ti accumulation in spinach as well as Cu Mn, Sr or Zn content in lettuce and its level in soil irrespective of the extraction method (0.03 M CH3COOH or 1 M HCl).
Studies were conducted to determine the concentration of anionic surfactants in selected waters in Tricity agglomeration (Gdańsk, Gdynia, Sopot). Water samples were taken from November 2001 to May 2002. The total concentration of anionic surfactants in the environmental samples was determined by Methylene Blue Active Substances Method (MBAS). The concentration of anionic surfactants in the analyzed waters ranged from 5 to 150 ^g/dm3. The highest surfactant content was observed in the Strzyża stream in Gdańsk and the Kacza river in Gdynia. Less polluted were the Haffner stream in Sopot and the Oliwski stream in Gdańsk.
