Descrizione delle condizioni meteo-climatiche in Toscana nell'anno 2021

Il progetto si è posto il duplice obiettivo di contribuire al quadro conoscitivo scientifico della materia e di qualificare, tra il 2021 e il 2022, decine tra Rifugi e altri siti d'interesse del CAI quali Stazioni di Terapia Forestale, secondo rigorosi criteri scientifici

Background The exposure to solar ultraviolet radiation is a significant risk factor generally underestimated by outdoor workers and employers. Several studies have pointed out that occupational solar exposure increased eye and skin diseases with a considerable impact on the lives and productivity of affected workers. The main purpose of this study was to evaluate the effectiveness against ultraviolet radiation of some measures recently undertaken for the protection of lifeguards in a coastal area of Tuscany. Methods Different shading structures (gazebos and beach umbrella) were tested during a sunny summer's day on a sandy beach by means of two radiometers; the UV protection offered by some T-shirts used by lifeguards was also tested in the laboratory with a spectrophotometer. Results The analysed shading structures strongly reduced the ultraviolet radiation by up to 90%, however a not always negligible diffuse radiation is also present in the shade, requiring further protective measures (T-shirt, sunglasses, sunscreen, etc.); the tested T-shirts showed a very good-excellent protection according to the Australian/New Zealand standard. Conclusion Results obtained in this study suggest how the adoption and dissemination of good practices, including those tested, could be particularly effective as a primary prevention for lifeguards who are subjected to very high levels of radiation for long periods.

The UV radiation risk is still little known and underestimated by outdoor workers and employers, as highlighted for example by the Plan of the Tuscany Region (Italy) "Risk from Solar UV Radiation in Outdoor Workers" which investigated several working sectors. Among these the seaside sector, well represented in Tuscany and mainly characterized by "outdoor" activities during the annual peak of UV radiation. Several studies have pointed out as occupational solar exposure increased eyes and skin diseases among which the non-melanoma skin cancer, with an excess risk up to three-fold increase in outdoor workers. Only recently the seaside sector in Tuscany is beginning to be aware of the use of protective measures such as shady areas and clothing (in addition to sunscreens, sunglasses, etc.) in order to reduce the professional risk due to solar UV exposure. In this work the UV protection properties offered by some shading structures were analysed during a summer clear sky day by means of two erythemally weighted broadband radiometers. Concerning clothes, were described some recent experiences of LaMMA/CNR-IBE on the UV protection offered by natural fabrics, while the ultraviolet protection factors of some T-shirts, used in the coastal area by beach lifeguards, were assessed. The shading structures blocked the direct component of the sun radiation, while the diffuse one, albeit also significantly reduced, continued to be not always negligible (due to environment reflection) especially considering a stay for several hours for the whole summer, therefore suggesting as good practice the maintaining of further protective measures (T-shirt, sunglasses, sunscreen, etc.) also in the shade. Results are shown both as instantaneous and cumulated doses for different time intervals along the day. The protective role of fabrics was emphasized and in particular, the tested T-shirts showed a very good-excellent protection (only one good protection) according to the New Zealand standard. The results show that also in the seaside context the dissemination of good practices, including those tested, could be particularly effective as primary prevention for workers who are subjected to very high levels of radiation for very long periods empowering employers and at the same time instil in workers an adequate awareness of the risk.

In recent years, the occurrence of Ostreopsis ovata (O. ovata) Harmful Algal Blooms (HAB) has increased in the coasts of the Ligurian Sea, causing problems to the marine environment and human health. Favourable conditions for O. ovata bloom are triggered by many drivers, many of which are still under investigation, but we hypothesize that this phenomenon can be simulated using a reduced number of major meteo-marine factors, namely water temperature and remixing. Satellite and model data obtained and derived from Copernicus service, namely Sea Surface Temperature (SST) and SignificantWave Height (SWH), were therefore investigated as possible proxies of these local factors. A simplified conceptual model, built on such proxies, was developed and applied to yield a synthetic indicator informative on O. ovata abundance. The model was tested in two study areas in the Ligurian Sea, Marina di Pisa and Marina di Massa in Tuscany, Italy. The results obtained show that the synthetic indicator is able to account for about 35% of the temporal variability of O. ovata bloom occurrence in the two study areas.
