Glyphosate
According to the USEPA [58], the lower limit associated with health
risk for glyphosate is 100 μg Kg−1 of body weight (b.w.) per day. Given
these values, a 65 kg person must consume more than 4.04 L day−1 of
water from San Antonio River to have health problems. Considering
that a typical Argentine adult drinks 2.3 L of water daily [13], the glyphosate
does not represent a risk to human health. However, taking into

of water from the San Antonio River during significant rain events
should not exceed 1.25 L rain events in order to prevent risk. Although
