Red fire

Mirex was detected in water samples taken in 1972 from areas in Mississippi that had been aerially treated with mirex to control the imported red fire ant (Spence and Markin 1974). Water samples taken from the bottom of a pond showed residue values that remained higher and more constant than those taken from the surface of the pond. Water showed the highest residues immediately after treatment (bottom, 0.53 pg/L [ppb] surface, 0.02 pg/L [ppb]), and detectable levels were still present as long as 3 months after treatment (bottom, 0.005 pg/L [ppb] surface, 0.003 pg/L [ppb]) (Spence and Markin 1974). 

In 1971 and 1972, mirex was detected in soil and sediment samples taken from areas in Louisiana and Mississippi that had been aerially treated with mirex to control the imported red fire ant (Spence and Markin 1974). In Louisiana, samples were collected throughout the first year after spraying. Soil and sediment residues in the Louisiana study peaked after 1 month (soil, 2.5 pg/kg [ppb] sediment, 0.7 pg/kg [ppb]) and gradually declined over the remainder of the year. In Mississippi, samples were collected for 4 months following spraying. Sediment residues in Mississippi also peaked about 1 month after spraying (1.1 pg/kg [ppb]) and gradually declined over the next couple of months. The... 

Laboratory studies have indicated that ozone at l%Mg/m (0.10 ppm) was lethal to adult houseflies Musca domestica L.) and caused them to lay fewer eggs. Two cockroach species Paraplaneta americana L. and Nauphoeta cinerea Oliver) and the red fire ant Solenopsis invicta Buren) were exposed to ozone at SSSug/m (0.30 ppm) for up to 10 days. There was no unusual mortality or evidence of direct injury to individual insects. The fire ant workers were stimulated to migrate inside their nest initially, but further observations indicated no disruption of social behavior. These reports do not suggest that free-ranging insects would be directly affected by ambient concentrations of ozone in natural ecosystems or agroecosystems. 

These bricks may therefore be called nlicecus oj etone bricks, and will no doubt prove admirably adapted for the construction of many kinds of chemical furnaces. A red fire-brick is likewise manufactured at Windsor, the analysis of the clay from which it is prepared being... 

The second German edition of Ruggieri s book (we have not seen the first) contains a Nachtrag or supplement which lists nine compositions,10 of which four contain Kali oxym. or potassium chlorate. These are (1) for red fire, strontium nitrate 24 parts, sulfur 3, fine charcoal 1, and potassium chlorate 5 (2) for green fire, barium carbonate 20 parts, sulfur 5, and potassium chlorate 8 parts (3) for green stars, barium carbonate 20 parts, sulfur 5, and potassium chlorate 9 parts and (4) for red lances, strontium carbonate 24 parts, sulfur 4, charcoal 1, and potassium chlorate 4 parts. Ruggieri says ... 

In firing with Vorlage, there is produced a red fire [a red glow] at the muzzle and in front of the piece. The smoke is colored red [by the glow]. This light however gives no reflection in the heavens. In fact it is visible and appreciable at a distance only if the piece is placed in such a way that... 

Generally said, the iron content is responsible for the red firing colour and the calcium content for the yellow colour. When the iron content is low and enough aluminium oxide is present, the free iron(III) oxide will bind with the silicates to form yellow compounds. Table 11.2.1 lists the baking colour as a function of the proportion of the iron(III) oxide, aluminium oxide and calcium oxide masses. 

Red Fire.—Strontium nitrate 500 parts, strontium carbonate. 300 parts, aluminium powder 200 parts, amorphous phosphorus 5 parts. 

In subsequent studies the simple terpenes EJi-a- and -/3-farnesene (3 8 and 39, respectively) were identified in dominant male urine.128 These odoriferous terpenes had long been recognized as components of cues released by a variety of other organisms (red fire ants, aphids, wild potato plants, fruit flies, and springbok). Because neither was detected in male bladder urine, attention was focused on the preputial glands as the source. Volatile components from dissected, fat-free preputial glands of dominant male mice were, again, preconcentrated on Ten ax. Subsequent GC analysis readily allowed identification of known 37 and 38. None of the earlier two components 36 or 37 was observed in the preputial volatiles, but both were present in the bladder urine of the same animals. 

Bed Fire according to Bratmschtveig-er. Nine parts of nitrate of strontium, 3 of shellac. 1.5 of chlorate of potassium. The snellae need only be coarsely powdered. The above 3 mixtures for red fire possess the advantage of not emitting injurious vapors, and can therefore be used in rooms, etc. 

Instead of the rather expensive precipitated chalky salts of strontia, carbonate of calcium, and the native sulphate of strontium (coelestine), may be used for preparing red fire according to the following receipts ... 

Strontium nitrate, Sr(N03)2 is made by dissolving strontium carbonate in nitric acid. It is mixed with carbon and sulfur to make red fire for use in fireworks, signal shells, and railroad flares. Strontium chlorate, Sr(ClD3)2, is used for the same purpose. 

Pine charcoal burns in combination with ammonium perchlorate at F/O = 2 10 producing a yellow flame, but no sparks or fire dust. A mixture of pine charcoal, sulphur and potassium nitrate in the weight ratio 30 10 60 burns producing pretty. orange red fire dust. This characteristic is generally seen with other charcoals but pine charcoal produces the most pretty fire dust of all. On the other hand, the phenomenon shows that pine charcoal does not complete the reaction and produces less gas in black powder-type compositions. Therefore pine charcoal is used to produce fire dust and not to obtain force. 

Red Fire. I, Forty parte of nitrate of strontium, 15 of sulphur, 5 of chlorate of potassium, and 2 of charcoal.
