Table 5.

Exposure biomarkers (μg/L) in subjects occupationally (n = 47) and non-occupationally (n = 53) exposed to pesticides from the Córdoba province. Results expressed as geometric means (GM), confidence interval (CI), median, range and 95th percentile (p95). Also detection frequencies (DF) are informed.
