They were testing dispersion of airborne particles, not toxicity. Zinc Cadmium Sulfide is visible under an ultraviolet light and that quality makes it easily identifiable in particle dispersion tests.So what is the point of spraying 'virtually nothing anymore than general pollution' or at least 'nothing toxic' to test the results?
I think Jazzy should have volunteered as the guinea pig to aid the war effort.
Asbestos causes Mesothelioma, which is one way of identifying asbestos related mortality.

The NRC (1997) reports the following as the major toxicological considerations of
cadmium and cadmium compound exposure:
1) The greatest risk from inhaled cadmium is to the lungs, causing lung cancer
2) Inhaled cadmium is most toxic to lungs, kidneys and the skeletal system
Carcinogenicity
In 1993, the International Agency IARC classified cadmium and cadmium compounds as
a carcinogen of Group 1:
The agent (mixture) is carcinogenic to humans. The exposure
circumstance entails exposures that are carcinogenic to humans
(IARC 1993b)
Within the past few years, however, conflicting reports have come out regarding
cadmium’s carcinogenic effect in humans. There are epidemiological links of
cadmium exposure with lung and prostate cancer in humans (Waalkes 2003; Waalkes 2000).
"Poison Playgrounds" was the local tv news report titled after the cancer society recieved so many complaints about the toxic hazards and this is an expert from the book.
Here's another stat for the addition and the chemicals most responsible for the toxicity outside it's school.

Note: Rankings are based on modeled concentrations and severity of chemicals known or believed to cause cancer.

21,679 of 127,809 schools have worse air.
- Manganese and manganese compounds 45% of overall toxicity
Definition: Manganese is used to produce pesticides, batteries and other industrial products. Although trace elements are found in food and are considered essential for good health, overexposure for long periods can cause mental and emotional disturbances and slow and clumsy body movements -- a disease of the brain called manganism. Children are more vulnerable to such exposures than adults. EPA says that it cannot be determined if there is a link between manganese and cancer.
- Trimethylbenzene, 1,2,4- 17% of overall toxicity
Definition: 1,2,4-trimethylbenzene is a colorless liquid that is used as a gasoline additive and in the manufacture of dyes, perfumes and resins. When inhaled, it can cause fatigue and drowsiness and can impair blood coagulation. No studies have been done of its potential as a carcinogen.
- Triethylamine 13% of overall toxicity
Definition: Triethylamine, a liquid, is used in the production of rubber, and to inhibit corrosion and remove salt from seawater. Triethylamine is highly irritating to the respiratory tract. Acute exposure may cause corneal swelling and halo vision. U.S. and international agencies have not classified triethylamine as to its carcinogencity. Exposure to triethylamine may cause skin, eyes, nose, throat, and respiratory tract irritation. Acute exposure to triethylamine vapors may cause corneal swelling and halo vision. High doses in animals cause heart, liver, and kidney injury. Central nervous system stimulation may possibly result from inhibition of monoamine oxidase
- Nickel and nickel compounds 3% of overall toxicity
Definition: Nickel, a metal, can be combined with other metals to make coins, jewelry, and stainless steel. People working in nickel refineries or nickel-processing plants have experienced chronic bronchitis, reduced lung function, and lung and sinus cancers. EPA classifies nickel refinery dust and nickel subsulfide as human carcinogens. Source: EPA, HHS
- Glycol Ethers 3% of overall toxicity
