Most of the research points to high levels of glyphosate contributing to NHL. No one knows for sure what levels of glyphosate the average human experiences per day. This makes it difficult to determine the exact effects small amounts of glyphosate have on humans. What science does know is that nearly every human being in the United States absorbs glyphosate throughout the day. We absorb glyphosate through our food, our water, and through breathing the air in our environment.
