Environmental Toxins & Liver Disease: A Link?
Study Says Low-Level Exposures May Explain Rise in Liver Disease
Environmental Toxins & Liver Disease: Second Opinion
The study results are "very important" and deserve attention, says Gina Solomon, MD, MPH, a senior scientist at the Natural Resources Defense Council in San Francisco, who reviewed the study for WebMD. "But it's hard to come to any solid conclusion based on this study alone."
"There is a chance they would find an association by statistical chance alone, because they looked at so many [toxins.]"
Some of the toxins associated with liver damage in the recent study, she says, have also been linked to liver damage in other studies, but at high levels of exposures. "The thing that is so dramatic about this study is they found associations at the levels that are in the general population. There's no surprise that these chemicals can cause liver disease, but previous research has always suggested that the doses needed to be much higher.
"The striking thing about this is that these are levels within the range that you or I might have in our bodies."
Although more study is needed, Solomon says that "If it holds up, it implies that some portion of the burden of liver disease out there in the U.S. may be due to chemical exposure outside the workplace."
Environmental Toxins & Liver Disease: Industry View
"The crop protection industry ... is one of the most highly regulated industries in the United States," says Susan E. Helmick, a spokeswoman for CropLife America, a trade organization representing makers of crop protection products and pesticides. "Safety to human health and any impact on the environment are always foremost in the development and use of crop protection products."
Further comment is not possible, she says, without seeing more findings than those in a brief abstract presented at the meeting.
