ABSTRACT
Introduction:
In the human skin exposed to ultraviolet (UV) radiation, melanogenesis occurs in two stages, accompanied by urinary excretion of Thormalen-positive melanogen (TPM). In Poland, no data are available on the course and intensity of melanogonesis in relation to UV exposure in an industrial region.
Material and Methods:
The Thormalen test was used for the collected samples (N=136) as modified by Matous and Suchoń.
Results:
Maximum environmental TPM content (0.67 μg/dm3) was observed in August.
Conclusions:
The time of UV exposure and local type of solar radiation promote melanogenesis.
