A case study of the Neolithic comb ceramic site Pezmog 4 of the Kama culture presents a situation when results of radiocarbon dating change long-existing concepts concerning the development of archaeological events. Until the early 2000s, the chronology of the Kama culture, distributed mainly in the Kama and Vychegda River basins, has been based on comparative-typological analysis. Estimates of the age of this culture changed from the 3rd millennium BC in the 1950s to the 1st half of the 4th millennium BC by the 1990s. Research concerning the Pezmog 4 site in the central Vychegda River basin in 1999–2002 has abruptly changed this chronological understanding. The data obtained put the age of the early stage of Kama culture within the time range 5750–5620 cal BC and allowed us to propose the existence of another way of early pottery distribution in the forest zone of eastern Europe at the beginning of the 6th millennium BC. This innovation probably penetrated from the trans-Ural region.

The paper contains the results of classification of rivers and streams of the Republic of Moldova according to classic Strahler method. Mentioned method was applied to estimate the hierarchical rank of the stream segments situated in 50 pilot basins using modern GIS techniques and drainage network of the GIS for Water Resources of Moldova. It was estimated that the maximal order of segments is 7 specific for the Raut and Ialpug rivers. Overall, length of 1st order streams forms 50%, while that of 7th order streams - < 1%. Additionally, stream number and frequency as well as drainage density were calculated for pilot river basins.

According to the Water Framework Directive 2000/60/EC, nonylphenol (NP) has been included in the list of priority hazardous substances and subject to cessation or phasing out of discharges, emissions and losses within an appropriate timetable not exceeding 20 years. The present work analyzed monitoring data on NP and its precursors (mono- and di-ethoxylates, nonylphenol-mono-ethoxylate and nonylphenol-di-ethoxylate) collected in a highly impacted river basin in Northern Italy in order to assess the effectiveness of the adopted measures for NP reduction, during two monitoring campaigns in 2003/04 and 2009/10, respectively, before and after the entry into operation of three new wastewater treatment plants (WWTPs) in Milan. The River Lambro is the main source of pollutants also for the River Po and the Adriatic Sea. Data collected in the present work showed that in the last 7 years the reduction of the different analytes was from 70% to 90%. Most of the reduction can be attributed to the substitution of nonylphenolethoxylates in industrial uses as demonstrated by a survey in the textile industrial district. The entry into operation of the new municipal WWTPs in Milan contributes about 10% of the reduction of the total NP load discharged by the River Lambro.
