However, due to the proven neurotoxic effects of lead at concentrations lower than 50 µg/L of blood, there is currently no established safe exposure limit. In order to establish and maintain the lowest practically achievable burden of lead exposure for the population, it is reasonable to implement measures in addition to regular monitoring, targeting vulnerable groups such as children and women of reproductive age.


Concentrations of total arsenic in blood, urine and breast milk in Slovenia are low and comparable to concentrations worldwide.

Long-term surveillance will be possible once regular national human biomonitoring is established.
