How do herbicides affect human health?

Glyphosate-based herbicides, such as the well-known “Roundup,” can cause DNA damages and act as endocrine disruptors in human cell lines (60) and in rat testicular cells (88), cause damages to cultured human cutaneous cells (89), and promote cell death in the testicular cells of experimental animals (88, 90).

How long do herbicides last in soil?

Herbicides can lie on the soil surface for seven to 10 days, perhaps even two weeks, without loss of efficacy.

Absorption of glyphosate through roots has been shown in several crop species, such as beets, barley, cotton, maize and rapeseed [13,15,16,17,18,19]. This exposure pathway is significant, because roots are the main intercept of glyphosate in field runoff.
