Cosa sa la Comunità scientifica di Taranto?
Lo scopo delle nuova rubrica di Legamjonici è proprio quello di informarvi circa le ultime ricerche svolte relativamente all’inquinamento della nostra città.
La scelta di pubblicare la fonte nella lingua con cui è stata resa nota l’informazione risiede nella necessità di preservare l’attendibilità dei dati scientifici presentati, escludendo ogni possibilità di dubbio su una ipotetica manipolazione dell’informazione stessa.
Ecco i primi 3 articoli della rubrica. Si tratta di ‘abstract’ (riassunti).
Il testo nella versione integrale non è facilmente reperibile nella versione gratuita, ma occorre acquistarlo o richiederlo agli atenei.
- Residential proximity to industrial sites in the area of Taranto (Southern Italy). A case-control cancer incidence study.

The association between cancer incidence and the residence near polluting facilities in an industrial area nearby Taranto has been investigated. Age, sex and occupational exposure were controlled as confounding variables in a case-control study (658 cases, 2092 controls). High risks were evidenced close to the steel mill (OR: 3.54), coke plant (OR: 4.80), mineral deposit (OR: 3.33) and shipbuilding (OR: 4.29) for pleural neoplasm, and to the steel mill (OR: 1.65) and shipbuilding (OR: 1.79) for lung cancer. After adjustment for occupational exposure, increasing trends of risk were observed both for lung and bladder cancers. Cancer risks were evidenced near industrial sites and the introduction of “occupational exposure” as a confounder modified significantly the risks with respect to distance from the source of pollution, particularly for pleural, lung and bladder cancers.

INTRODUCTION: In 2009 the limit value of benzo(a)pyrene (BaP) in ambient air of 1.0 ng/m3 has been exceeded in the urban district of Taranto near to the industrial area, where a several large plants are located, including an integrated cycle steel plant.
OBJECTIVE: To identify emission sources and quantify relative contribution to the PAHs levels; to estimate health impact associated to PAHs exposure in general population.
METHODS: Multivariate receptor models have been used. Concentration of PAHs measured in 4 location in Taranto in 2008-2009 have been analyzed. 5 different models estimated profiles of unknown sources and identified significant chemical species. To compute the lung cancer risk the WHO unit risk estimate for BaP (8.7 x 10(5) ng/m3) has been adopted.
RESULTS: Models employed identify 3 to 4 emission sources. Estimated profiles have been compared with measured ones. Based on the average annual BaP level measured (1.3 ng/m3), 2 attributable cancer cases in the district Taranto population are estimated to result from a life-time exposure.
CONCLUSIONS: Among different emissive sources, the analysis identifies theoretical sources whose profiles, compared with observed data, allow to identify dominant contributions to PAHs pollution and to design corrective actions to reduce environmental and health impact.

Polychlorinated biphenyls (PCBs) and 17 parent polycyclic aromatic hydrocarbons (PAHs) were determined in surface sediments from nine stations in the Mar Piccolo of Taranto (Ionian Sea, Southern Italy). Total PAH concentrations ranged from 380 to 12,750 microg/kg d.w., while total PCB levels ranged from 2 to 1684 microg/kg d.w.; this values were higher than those found in others marine coastal areas of the Mediterranean Sea. For PAHs, low molecular weight/high molecular weight, phenanthrene/anthracene and fluoranthene/pyrene ratio were used for discriminating between pyrolitic and petroleum origin. Results showed that PAHs were mainly of pyrolitic origin. PCB and PAH levels in sediments were compared with Sediments Quality Guidelines (ERM-ERL, TEL-PEL indexes) for evaluation probable toxic effects on marine organism. Finally, ERM and PEL quotients were used to evaluate the degree to which chemicals exceed guidelines. Results suggest an ecotoxicological risk for benthic organisms mainly in the first inlet, where high concentrations of PCBs were found in sediments influenced by harbour activities.
