140. Actually our neighborhood was sprayed 4 days in a row with 4 yr old Malathion

that workers found in a shed when they ran out of the pyrethroids they had been spraying on us for years from trucks in the middle of the night. You can bet I got me a toxic tort lawyer!

Malathion Becomes More Toxic When Stored for 3 months
or When Temperature Increases
SOURCE: Journal of Agricultural Food Chemistry, 25(4) 46-953, 1977

The technical grade malathion (the type we are exposed to) contains approximately 11 impurities. It is these impurities which scientists state are the main poisoning ingredients in malathion. One impurity has been shown to be approximately 500 times more toxic than purified malathion (based on the amount needed to kill test animals - LD-50 is 20 mg/kg compared to 10,000 mg/kg for purified malathion). It is called - O,S,S-trimethyl phosphorodithioate (OSS-TMP for short). Researchers state this, and other malathion impurities, actually increase in amounts during simple storage (especially 3-6 months after manufacture), making malathion far more toxic than when it was first manufactured. OSS-TMP and other impurities have also been shown to increase even more rapidly when exposed to temperatures around 100 degrees. How high do the temperatures become for the drums sitting in direct sunlight or at the Tampa Airport in the non-air conditioned rooms?

Immune System Weakens after Malathion Exposure
SOURCE: The Journal of Immunology, 140(2):564-570

immune cells attack cancerTechnical 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: This research addresses the paradox regarding the New York City malathion spraying.
As encephalitis has been shown to only affect people with a weakened immune system who are unable to efficiently combat the disease (i.e. elderly and immune compromised individuals) it must be considered that malathion has the potential in itself to increase encephalitis cases as the spraying of the pesticide can weaken a person's immune system, thereby, making them more vulnerable to the disease.

MALATHION UNDERGOES DANGEROUS REACTION IN SUNLIGHT
Malathion undergoes a chemical reaction in sunlight called "photolysis" which results in increasing the formation of the highly toxic trimethyl impurities. -

Malathion Breaks Down into even More Toxic - Malaoxon
SOURCE: Bulletin of Environmental Contamination Toxicology, 57 05-712, 1996

In trying to calm the fears of Tampa residents, representatives for the Florida Department of Agriculture have made public statements that after application, malathion "breaks-down" in a matter of hours. What they don't tell you is that malathion can actually break-down into compounds which are more poisonous than the malathion itself. This is, in fact, the conclusion of research from a graduate project by researcher N. E. Barlas at the Department of Biology, Hacetepe University, Turkey. Barlas went on to say, "The disappearance of pesticide residues at a given location does not mean the end of the problem. Pesticides can be translocated, bioconcentrated or converted into more dangerous chemicals." The breakdown fate of malathion was studied by adding malathion to soil samples containing 6 species of soil bacteria known to breakdown the pesticide. After 10 days the samples were analyzed. Malathion content had reduced from 100 down to 25 micrograms, so therefore, the Florida Department of Agriculture spokes people are correct when they say it "breaks down" relatively quickly (although in this case not in a matter of hours). However, even more important, Barlas found that new chemicals were formed in this breakdown process including 14 micrograms of monocarboxylic acid and about 8 micrograms of the highly toxic malaoxon. Barlas then exposed mice to the technical grade malathion and another group to the breakdown products just mentioned. Results showed even the mice exposed to the break-down products of malathion showed significant decreases in spleen weights and significant changes in liver blood tests which were suggestive of liver damage. Barlas summarized by stating, "It may be concluded that commercial malathion and it's degradation products together have detrimental effects on mice over a period of 15 weeks of treatment."
