BIOMARKERS AND RISK FACTORS AFTER LEAD AND CADMIUM EXPOSURE IN THE AREA OF COPŞA MICĂ
Abstract:
Industrial and urban development in the last decades in the absence of adequate environmental protection measurements led to an increased level of pollution in Romania. Environmental lead levels indicated the need to assess the exposure of susceptible population groups (children) living in the area of influence of a primary smelter in Copsa Mica. Blood lead levels and urinary cadmium levels of a susceptible population group (children aged 3-15 years) were assessed in a cross-sectional study. Most of the subjects (72%) had blood lead levels between 10-30 mg/dL, in case of 13% of them, blood lead levels fall within 30-40 mg/dL, while 5% of them had blood lead levels exceding 40 mg/dL. Only 10% of the investigated subjects had blood lead levels bellow 10 mg/dL. Urinary cadmium levels were bellow the detection limit of the method used for measuring, in case of most of the investigated subjects. The study found negative and statistically significant correlations between blood lead levels and children height.
