In fresh evidence of the pervasive nature of pesticides, more than 80 percent of urine samples drawn from children and adults participating in a US health study contained a weedkilling chemical linked to cancer and other health problems.

The June 30 report by a unit of the Centers for Disease Control and Prevention (CDC) found that out of 2,310 urine samples collected, 1,885 were laced with detectable traces of glyphosate, the active ingredient in herbicides sold around the world, including the widely used Roundup brand.
