The monitoring of the epi-benthic dinoflagellate Ostreopsis ovata was carried out during the summer seasons of 2007 and 2008 all along the marine coastal areas of the Puglia region (Southern Italy, Central Mediterranean). Eighteen monitoring sites were investigated in both years from June to September at 15 day-time intervals, collecting water samples in order to measure both the Ostreopsis ovata density and microbiological parameters (Fecal Coliforms and Streptococci). The microbiological parameters were measured as indirect indicators of pollution from anthropogenic sources. Ostreopsis ovata highest density values were estimated for both years in the monitoring sites located northbound from the town of Bari, on the southern Adriatic coast. Results from microbiological analysis showed a similar distribution pattern. The relationship between O. ovata abundance and microbiological pollution was investigated by using synthetic indices (Ostreopsis-Score and Bacteriological Quality Index respectively) and the correspondence between the dinoflagellate blooms and humaninduced pollution pressures on these marine coastal areas was highlighted. © by PSP.

During the winter season 2008/2009 for the first time a massive cyanobacteria bloom occurred in the artificial lake of Occhito, the main reservoir in the province of Foggia (Southern Italy, Apulian Region). The toxic species Planktothrix rubescens was identified and monitored from January to July 2009 in order to quantify the population density and microcystin production both in the lake and in treated waters for human consumption. The bloom reached the main peak during March 2009, when the highest values of 140- 160*106 cells/l were recorded in the lake (at the same time the microcystin concentration was 11-31 μg/l). The water treated by means of sand - activated carbon filtering and chlorination processes highlighted significant removal rates, from 34% to 99% for P. rubescens cell density and from 52% to 100% for microcystin. © by PSP.
