Environmental and breathing zone samples were analyzed for formaldehyde (50000), metals, organic solvents, inorganic fluorides crystalline silica (7631869) at Wyoming High School (SIC-8210), Wyoming, Ohio in January and February, 1985. The evaluation was requested by the principal to investigate chemical exposures in the art and biology departments. Lead (7439921), cadmium (7440439), and hexane (110543) concentrations were below their relevant standards. Formaldehyde concentrations in the biology department averaged less than 1.5 parts per million (ppm) when collected with sorbent tubes, but ranged from 0.3 to 7ppm on direct reading, colorimetric indicator tubes. The OSHA standard for formaldehyde is 3.0ppm. Area air samples contained 14.2 to 61 micrograms per cubic meter inorganic fluorides. One settled room dust sample contained 16.7 percent quartz. Bulk samples and some art supplies contained 20 and 42.5 percent lead, 0.03 and 0.05 percent arsenic (7440382), and 0.03 percent cobalt (7440484). The author concludes that a hazard exists from formaldehyde exposure and potential hazards from lead, arsenic, and silica exposure. Recommendations include reducing formaldehyde exposures during animal dissections and keeping the art department clean to reduce the potential hazards from chemicals in settled dust.
