“…Moreover, according to the CAREX study [36], solar radiation exposure in Italy, as well as in many other countries, is the occupational carcinogenic exposure involving the highest number of workers, just after passive tobacco smoke, e.g., in Italy, more than 700,000 outdoor workers, of whom 3200 are fishermen daily exposed to carcinogenic solar UV rays [36], and we should expect at least 1000 UV-inflicted occupational skin cancers (OSC) per year in Italy, but only a few dozen are reported each year to the compensation authority [37], and the same underreporting also happens in other countries [38,39]. Among the major issues in Europe for further improvements in the prevention of occupational solar UV exposure [7,40] there is the lack of established occupational exposure limits; only limits for artificial UV are available, but if we would apply these limits to outdoor work situations—and it can be possible, as solar UV radiation at the sea level is almost nonmeasurable below 300 nm of wavelength, so that the difference between the ICNIRP weighted and the erythemally weighted spectra can be considered negligible [6,14,27,28,29]—they would be largely exceeded, as shown in many studies [7,18,19,20,21,22].…”
