Effects of Pesticides on the Immune System

Abstract
With pesticide use and exposure, and review of pesticides altering the immune system, this article shows data from four groups of patients at the Environmental Health Centre-Dallas, and two case reports are presented. These data not only revealed pesticides in most patient populations around the world, but also 81% out of 107 patients with initial exposure had depressed levels of T and B cells. There was a significantly greater frequency of several abnormal immune parameters in 40 proven chemically sensitive patients with more than two organochlorine pesticides than in 20 patients with less than two. Six patients showed improvement of various T- and B-cell parameters as pesticides cleared from the bodies.
