In addition to the potential for cancer - (
The individual in the court case was diagnosed with Non Hodgkins Lymphoma), researchers (
from studies done before 2009) have found that one of roundup’s inert ingredients can kill human cells, particularly embryonic, placental and umbilical cord cells (
"study done in more than one country"). is a surfactant, or detergent, derived from animal fat. It is added to Roundup and other herbicides to help them penetrate plants' surfaces, making the weed killer more effective.
"But some inert ingredients have been found to potentially affect human health. Many amplify the effects of active ingredients by helping them penetrate clothing, protective equipment and cell membranes, or by increasing their toxicity."
Weed-Whacking Herbicide Proves Deadly to Human Cells (from 2009 article)
Used in gardens, farms, and parks around the world, the weed killer Roundup
contains an ingredient that can suffocate human cells in a laboratory, researchers say

Such additives in pesticide formulations are commonly called "inert" ingredients or adjuvants, and little is known about these ingredients and their occurrence and transport in, and effects on, the environment. This USGS study is the first step in investigating the environmental fate and effects of POEA in herbicide applications.
