Abstract The aim of this paper is to show the results of lead and cadmium values measured on deciduous teeth of children from the city of Cartagena (Spain), and their relationships with different variables. A total of 834 samples were processed. Lead data shown a positively skewed distribution and fitted to a log- normal distribution, meanwhile cadmium data did not. The true arithmetic mean and standard deviation of cadmium values was estimated censoring data by 10 ng/g, where the cadmium distribution looks log-normal. No statistically significant differences coul
