There are many other compounds that have been shown to cause immunosuppression such as organophosphorus compounds, ozone, metals, and organotin compounds. Dialkyltin... 

SAFETY PROFILE Poison by ingestion and intraperitoneal routes. A trace mineral added to animal feeds. Potentially explosive reaction with charcoal + ozone, metals (e.g., powdered aluminum, copper), arsenic carbon, phosphoms, sulfur, alkali metal hydrides, alkaline earth metal hydrides, antimony sulfide, arsenic sulfide, copper sulfide, tin sulfide, metal cyanides, metal thiocyanates, manganese dioxide, phosphorus. Violent reaction with organic matter. When heated to decomposition it emits very toxic fumes of I and K2O. See also lODATES. 

The oxidative degradation of triazine herbicides like Atrazine [2-chloro-A4-ethyl-V6-iso-propyl-1,3,5-triazine-4,6-diamine (15)] can be effected by hydroxyl radicals generated from ozone, metal oxides or hydrogen peroxide/iron(II) salts (Fenton s reagent).22...

Lim) often cause the greatest alteration in pulmonary function because they can penetrate farther into the alveoli, whereas the larger particles are deposited in the upper respiratory tract. Increase in airway resistance at high acid concentrations has been demonstrated by several authors. Presence of ammonia in expired air has been reported to afford some protection in humans Synergism has been demonstrated when sulfuric acid is deposited on zinc oxide dusts in the presence of sulfur dioxide, and also when combined with nitrogen dioxide or sulfur dioxide, ozone, metallic aerosols, and sulfuric acid. 

It is slightly soluble in water, giving a neutral solution. It is chemically unreactive and is not easily oxidised or reduced and at room temperature it does not react with hydrogen, halogens, ozone or alkali metals. However, it decomposes into its elements on heating, the decomposition being exothermic ... 

Pure silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. The alloys of silver are important. 

Silicone rubbers have excellent ozone and weathering resistance, good electrical properties, and good adhesion to metal.

Among toxic pollutants that may enter the environment, hydraziae is one of the less persistent because it reacts with oxygen and ozone, particularly in the presence of catalytic surfaces such as metals, oxides, etc. The final products of these reactions are innocuous nitrogen and water. 

The relevant properties of peroxide and superoxide salts are given in Table 4 (see Peroxides and peroxide compounds, inorganic). Potassium peroxide is difficult to prepare and lithium superoxide is very unstable. The ozonides, MO3, of the alkah metals contain a very high percentage of oxygen, but are only stable below room temperature (see Ozone). 

The inoigaiiic chemistiy of ozone is extensive, encompassing virtually every element except most noble metals, fluorine (qv), and the inert gases. Repotted second-order rate constants (L/(mol-s)) at 20—23°C refer to the disappearance of ozone unless otherwise stated. 

Metals and Metallic Ions. Under appropriate conditions, ozone oxidizes most metals with the exception of gold and the platinum group. When oxidized by ozone, heavy metal ions, such as Fe and Mn , result in the precipitation of insoluble hydroxides or oxides upon hydrolysis (48—50). Excess ozone oxidizes ferric hydroxide in alkaline media to ferrate, and Mn02 to MnO. ... 

Because ozone formation occurs only within these microdischarge channels, ozone-production efficiency for the most part depends on the strength of the microdischarges, which is influenced by a number of factors such as the gap width, pressure, properties of the dielectric and metal electrode, power...

Ozonation can be enhanced by the addition of ultraviolet (uv) radiation. This combination can be effective in degrading chlorinated organic compounds and pesticides. In addition, metal ions such as iron, nickel, chromium, and titanium [7440-32-6] can act as catalysts, as can ultrasonic mixing. 

Many of the metal chlorites are not particularly stable and will explode or detonate when stmck or heated. These include the salts of Hg", Tl", Pb ", Cu", and Ag". Extremely fast decomposition with high heat evolution has been noted for barium chlorite [14674-74-9] Ba(Cl02)2, at 190°C, silver chlorite [7783-91-7] AgC102, at 120°C, and lead chlorite [13453-57-17, at 103°C (109). Sodium chlorite can be oxidized by ozone to form chlorine dioxide under acidic conditions (110) ...

Free-radical initiation of the chain reaction of oxidation can arise from the action of heat, light, metal ions and, sometimes, ozone on a variety of chemical moieties such as those indicated in Table 7.4.
