  author={Jaime F Abarca and Claudio C Casiccia},
Background:  Punta Arenas, Chile, the southernmost city in the world (53°S), with a population of 154 000, is located near the Antarctic ozone hole (AOH) and has been regularly affected by high levels of ultraviolet‐B (UV‐B) radiation each spring for the last 20 years. Large increases in UV‐B associated with the AOH have been measured with increases in UV‐B at 297 nm of up to 38 times those of similar days with normal ozone. Recently we reported significant increases in sunburns during the… 
The relationship between the ozone layer and skin cancer
In the recent decades, a sustained increase in the worldwide incidence of skin cancer has been observed and Chile is not the exception. The most important risk factor is the exaggerated and repeated
Erythemal irradiance at the Magellan's region and Antarctic ozone hole 1999-2005
The most austral zone of the Southern Cone of South America, which is sometimes under the influence of the Antarctic Ozone Hole (AOH), occasionally receives enhanced levels of ultraviolet B radiation
Dermatological effect of UV rays owing to ozone layer depletion
In recent years, one of the major threat for the earth is the depletion of ozone layer that accelerates the incoming amount of various solar rays including the UV rays. It has an drastic effect on

The temperate forests of the southern hemisphere are the most likely forests to be affected by increased levels of ultraviolet-B (UVB) radiation resulting from reduced ozone, and the morphological changes, physiological effects, and protection mechanisms, particularly UV absorbing compounds that result from present day and increasing UVB radiation are described.
An exploratory analysis of low-ozone events during spring and summer months over Cape Point, South Africa
Decreased stratospheric ozone levels contribute towards increased ultraviolet (UV) radiation at the Earth's surface with potential negative impacts on public health. This study sought to determine
Epidemiology of Skin Cancer: Role of Some Environmental Factors
Higher temperatures accompanying climate change may lead, among many other effects, to increasing incidence of skin cancer, and the impact of changes in ambient temperature will influence people’s behavior and the time they spend outdoors.
Factors influencing ultraviolet radiation dose to developing frogs in northern vernal pools
UV-B risk to vernal pool species is greater than predicted in previous studies, and amphibian UV-B exposure could reach levels of great concern given changes in light regimes, climate change, and forest harvesting.

This chapter follows the function of UVR in the onset and development of BCC, and describes the factors that influence BCC induced by UVR, and also reviews the recent advances of pathogenesis of BCC inducedBy UVR from the genetic and inflammatory aspects.
Quantification of the Environmental Solar Ultraviolet Radiation Field at the Human Eye and the Investigation of Peripherally Focused Rays.
The increase of terrestrial solar ultraviolet radiation (UVR) due to the reduction of the ozone layer has promoted a variety of research into establishing the impact of this elevated potential dose
The extra-terrestrial vacuum-ultraviolet wavelength range
Electromagnetic radiation in the vacuum-ultraviolet (VUV) and extra-terrestrial range at wavelengths from 10 nm to 300 nm is absorbed in the upper atmosphere by ozone, molecular and atomic oxygen,


Increase in sunburns and photosensitivity disorders at the edge of the Antarctic ozone hole, southern Chile, 1986-2000.
An acute impact on human health (sunburn) occurred because of abrupt ozone depletion and the accompanying increase in UVB during the mid and late austral spring of 1999.
Abstract One of the most significant environmental changes that occurs in our atmosphere, the ozone depletion in the stratosphere, produces increases in damaging UV-B radiation at the surface,
Measurements of enhanced springtime ultraviolet radiation at Palmer Station, Antarctica
Measurements of ultraviolet solar spectra from Palmer Station, Antarctica have defined the surface radiation environment of the region during the Austral spring of 1988. At wavelengths where

It will be several years before the beginning of an ozone recovery can be unambiguously identified at individual locations, and future changes in greenhouse gases will affect the future evolution of ozone through chemical, radiative, and dynamic processes.
Skin cancer and solar UV radiation.
The relationship between the most fatal skin cancer, i.e. malignant melanoma and solar UV exposure is, however, still unclear and needs to be clarified to optimise preventive measures and minimise mortality from skin cancers.
The ozone hole over Punta Arenas, Chile
Three fundamental questions are addressed for the location of Punta Arenas (53.0°S, 70.9°W), Chile: Does the Antarctic ozone hole extend over the city? If so, at what height is most of the ozone
Estimate of the wavelength dependency of ultraviolet carcinogenesis in humans and its relevance to the risk assessment of a stratospheric ozone depletion.
This carcinogenicaction spectrum for humans resembles the action spectrum for ultraviolet-induced erythema (sunburn), and results in small adjustments of earlier estimates of the effects of a stratospheric ozone depletion on skin cancer incidences.
Antarctic Ozone Hole: Possible implications for ozone trends in the southern hemisphere
Satellite-borne instruments (the Total Ozone Mapping Spectrometer and the Solar Backscattered Ultraviolet Instrument) show that, compared to 1979, total column ozone has a year-round decrease of more

A series of experiments were performed to provide more specific comparative data by testing the hypothesis that the action spectrum for carcinogenesis parallel that for erythema, which indicated a decreasing potency from 300 to 310 to 320 nm.
