Table 4

Comparison of metal load between mothers according to their use of house–agricultural chemicals. Subgroups are not users-subgroup 1 (n=352) or users subgroup 2 (109), of any of the chemicals listed in figure 3D . Analysis was by multiple quantile regression on median values as linear function of the independent variable, ‘use of chemicals’. There was no significant difference for the load of all metal tested (p > 0,3) between the two groups
