This article presents information related to the presence of lead, cadmium and zinc in tissues of Roe Deer. The term" hot spots" is used for areas where wildlife is the most threatened by toxic substances. These include areas near industrial and electricity generating centres. An industrial area in the northern part of Slovenia with a centuries-old tradition of mining and manufacturing of lead and zinc, represents an extreme example of a" hot spot" environment. Lead excavation started in here in 1424, while the start of well organised metallurgical activity dates from 1893. Lead production reached its peak in the seventies when approximately 28,000 tons of lead were produced per annum.
