Scientist have shown that there is no apparent connection between common chemicals, like pesticides and herbicides, and developing amyotrophic lateral sclerosis (ALS, aka Lou Gehrig’s disease). However, there is one exception.

Marc Weisskopf, PhD, Harvard University, Boston, reported at the American Academy of Neurology annual meeting, Chicago, that people reporting a ten year or greater exposure to formaldehyde had a 34% greater risk of developing ALS than those without exposure to formaldehyde.

Although the study results are preliminary the finding is surprising because formaldehyde has not been identified as having a possible link to ALS previously.

Formaldehyde is used in manufacturing of particle board and other wood products, permanent press fabrics, glues, and household products like cosmetics and shampoo. It is also used in medical laboratories and mortuaries as a preservative and industrial disinfectant.
