According to a report by the Washington,
D.C. based group, World Resources Institute (WRI), many pesticides appear
to be increasing the incidence of infections, pneumonia, ear infections,
and tuberculosis. The three pesticides listed as causing this problem were
DDT, malathion, and the pesticide aldicarb. A summary of the report, appearing
in the March 9, 1996 issue of Science News, outlined many of the studies
linking pesticides with weakening of the immune system. One of the groups
commissioned researchers, Dr. Lyudmila Kovtyukh, of the Academy of Sciences
in Kishinev, Moldova (a republic between Romania and Ukraine), found that
children living in areas where pesticides had been most heavily applied
experienced elevated rates of acute respiratory diseases (including pneumonia),
as well as many other signs of immune system weakness. If you would like

Immune System Toxicology.
Technical grade malathion contains chemical impurities which have been found to weaken immune system function, including a weakening of a type of white blood cell called "cytotoxic lymphocytes" (which attack cancer cells and virus infected cells). The picture at right shows six of these white cytotoxic lymphocytes (let's call them CTL's for short) successfully attacking a cancer cell (National Geographic). These lymphocytes can also attack viruses in the body. Malathion has now been shown to significantly weaken the CTL's ability to perform their job effectively.
Chem-Tox Comments: Obviously, the
consequences of not having lymphocytes remove viruses or cancer efficiently could result from either mild
to serious health disorders.

(Opinion:
If you not outraged by what you've been reading, then you're not paying
attention. - Get angry and stay angry. They (chemical companies) are
marketing Malathion for use on children and adults for lice and scabies.)
