That is a nice website - thanks for the info. I feel better about
glyphosate now. (My neighbor uses it)

BTW Does anyone know what means "the 96-hour LC50 was 8.3 mg/l with
Roundup and 38 ppm with glyphosate" or " The acute oral LD50 in the
rat is 5,600 mg/kg." ? Presumably LC50 is some sort of statistical
measure.
