Assessment of water pollution and suitability to fish life in six Italian rivers.

This paper reports the results of a monitoring programme of six rivers (Serchio, Cecina, Cascina, ERa, Elsa and Pavone) that drain north-west Tuscany (Italy). In this area, agricultural, industrial and urbanization pressures affect water quality, also in terms of suitability for the survival of aquatic organisms. The river waters were monitored for several physico-chemical parameters (temperature, dissolved oxygen, suspended solids, total ammonia, nitrites, Cu, Cd, Cr, Ni and Pb) in order to assess the anthropogenic impact on the environmental conditions of these watercourses and their suitability for fish life.

Mutagenicity and chemical analysis of airborne particulate matter collected in Pisa.

The genotoxic effects of airborne particulate samples collected from two urban areas during various traffic intensity levels were evaluated using the yeast Saccharomyces cerevisiae (D7 strain) and Salmonella typhimurium (TA98 and TA100 strains). Standard protocols were used, in compliance with recent legislation. Airborne particulate data reveal that genotoxic effects were more evident in the samples collected in the area with intense moving traffic than in the area with limited traffic.

Ozone measurements in the urban and extra-urban areas of Pisa during the summer of 1995.

During the Summer of 1995, atmospheric ozone concentrations were measured in five areas with different geographical and environmental characteristics. The five areas included: 1. Pisan coastline.
