DNA damage on B and T lymphocytes in non-exposed group (a) and farm owners group (b). For both groups, S0 samples were collected at P0 period (January) and S4 samples were collected at period corresponding to the intensive spraying period P4 (May–June). For the farm owners group, another sample (S2 sample) was collected at P2 period (after the first day of spraying season). Boxes are limited by first and third quartiles separated by the median; thin vertical lines represent minimum and maximum values in the 10–90th percentile range. Points are the extreme values. Statistical analysis was performed with paired samples Student’s t test
