Solar ultraviolet radiation (UVR, 280-400 nm) is known to cause a number of detrimental effects in aquatic organisms. The area of Patagonia, which is sometimes under the influence of the Antarctic ozone “hole”, occasionally receives enhanced levels of ultraviolet B radiation (UV-B, 280-315 nm). Great efforts have been put into creating a database for UVR climatology by installing a variety of i...

In shallow subarctic ponds Daphnia and their algal food are often exposed to solar ultraviolet radiation (UVR). It was previously demonstrated that direct exposure of Daphnia to UVR may result in sublethal damage to Daphnia‘s intestinal system. This led to the hypothesis that, as consequences of such exposures, Daphnia may be experiencing a situation similar to starvation. We examined, in contr...

Our laboratory has shown that arsenite markedly increased the cancer rate caused by solar-simulation ultraviolet radiation (UVR) in the hairless mouse skin model. In the present study, we investigated how arsenite affected DNA photodamage repair and apoptosis after solar-simulation UVR in the mouse keratinocyte cell line 291.03C. The keratinocytes were treated with different concentrations of s...

Using micro-UV-irradiation versus whole-dorsal irradiation for inducing cutaneous carcinomas in Skh:HRI mice and an assay for UV radiation (UVR)-induced systemic tumor immunosuppression, the dependence upon systemic immunosuppression for the growth of UVR-induced carcinomas was examined. Squamous cell carcinomas were produced by repeated microirradiation of 0.8-cm2 middorsal skin with xenon are...

Ultraviolet radiation (UVR) has been identified as the primary etiologic agent for the induction and promotion of most skin cancers. The first associations between solar UVR and skin cancer were acknowledged by the scientific community in 1927. Since then, increasing evidence for the role of UVR in the causation of skin cancer has resulted in the listing of solar and artificial UVR as a human c...

Ultraviolet radiation (UVR) can suppress essential molecular and cellular mechanisms during early development in living organisms and variations in solar activity during early development may thus influence their health and reproduction. Although the ultimate consequences of UVR on aquatic organisms in early life are well known, similar studies on terrestrial vertebrates, including humans, have...

Emiliania huxleyi, the most abundant coccolithophorid in the oceans, is naturally exposed to solar UV radiation (UVR, 280-400 nm) in addition to photosynthetically active radiation (PAR). We investigated the physiological responses of E. huxleyi to the present day and elevated CO2 (390 vs 1000 μatm; with pH(NBS) 8.20 vs 7.86) under indoor constant PAR and fluctuating solar radiation with or wit...

This overview highlights the risk of skin diseases arising in workers exposed to ultraviolet radiation (UVR) at their workplace. There is a plethora of skin manifestations in outdoor workers such as seamen, fishermen, farmers after acute intense or long-term exposure to solar UVR, but some cutaneous diseases may also develop in indoor workers exposed to artificial sources. In recent years, inve...

The exposure of outdoor workers to solar ultraviolet radiation (UVR) has been known for some time. Measurements of erythemally weighted UVR are usually related to days of exposure and to the anatomical distribution of UVR on the human body. The aim of this research is to describe the UVR exposure of workers during a strawberry production cycle in order to assess the UVR hazard and to identify t...
