dc.description.abstract |
Solar ultraviolet radiation (UVR) monitoring is important since it depends on several
atmospheric parameters which are associated with climate change and since excess solar UVR
exposure and has significant impacts on human health and wellbeing. The objective of this study
was to investigate the trends in solar UVR during a decade (2009–2018) in Saint-Denis, Reunion
Island (20.9 S, 55.5 E, 85 m ASL) and Cape Town, South Africa (33.97 S, 18.6 E, 42 m ASL). This
comparison was done using total daily erythema exposure as derived from UVR sensors continuously
at both sites. Climatology over the 10-year period showed extreme UVR exposure for both sites.
Slight changes with opposite trends were found, +3.6% at Saint-Denis and 3.7% at Cape Town.
However, these two sites often experience extreme weather conditions thereby making the trend
evaluation di cult. Human exposure assessment was performed for hiking activities at two popular
high-altitude hiking trails on the Maïdo–Grand Bénare (Reunion) and Table Mountain (Cape Town)
with a handheld radiometer. Extreme exposure doses of 64 SED and 40 SED (Standard Erythemal
Dose, 1 SED = 100 J.m 2) were recorded, respectively. These high exposure doses highlight the
importance of raising public awareness on the risk related to excess UVR exposure at tourist sites,
especially those at high altitude. |
