The impairment of liver function by low environmentally relevant doses of glyphosate-based herbicides (GBH) is still a debatable and unresolved matter. Previously we have shown that rats administered for 2 years with 0.1 ppb (50 ng/L glyphosate equivalent dilution; 4 ng/kg body weight/day daily intake) of a Roundup GBH formulation showed signs of enhanced liver injury as indicated by anatomorphological, blood/urine biochemical changes and transcriptome profiling.Wow! Damage at parts per billion! Or 4 NANOgrams per kg of body weight! Damage occurs at concentrations far below EPA standards.
This was a 2 year study on female rat liver tissue. The rats suffered from Non-Alcoholic Fatty Liver Disease (NAFLD). NAFLD currently affects 25% of the US population. NAFLD can progress to the more serious condition non-alcoholic steatohepatitis (NASH). Over the 24 months the trigliceride levels rose in the rates. See Figure 1 graph in study.
