Aerosols of particles larger than 2 pm also cause damage to the upper respiratory system. Arsenic oxides, sulfides, and chlorides are used in a variety of industries, such as manufacturing of colored glass, ceramics, semiconductors, and fireworks and in hide processing. However, upper respiratory exposure to these compounds is most likely to occur in ore smelting industries and in pesticide manufacturing.

Incorporation of fibres, whiskers or particles in a ceramic/glass-ceramic matrix can result in a tough ceramic material. This happens because...

Fluids were injected into a central well, surrounded by 6 production wells at distances from about 200-360 ft (Figure 1). Injection equipment consisted of an air compressor, a pump for the 25 drums of 60% active surfactant that were used, a pump for dilution of the concentrated surfactant solution with plant water, a foam generator (2-ft long, 3-in. diameter pipe packed with ceramic particles) that optionally could be bypassed, and a sight glass for visual observation of the fluids before they entered the well.
