Abstract
Environmental and breathing zone samples were analyzed for lead (7439921) at Mystic Seaport (SIC-3731), Mystic, Connecticut in January and February, 1985. The evaluation was requested by the facility to assess lead exposures during cutting and rivetting operations aboard a lead painted, iron hulled ship. Blood lead and erythrocyte protoporphyrin (EP) concentrations were determined in 10 shipfitters. Noise exposure measurements were made. Breathing zone lead concentrations averaged 257 micrograms per cubic meter (microg/m3). The OSHA standard for lead is 50microg/m3. Two short term samples taken while the exhaust ventilation was temporarily disconnected contained 375 and 718microg/m3 lead. Blood lead concentrations averaged 37.8microg/deciliter (dl). Smoking shipfitters had higher blood lead concentrations than nonsmokers, 47microg/dl versus 32microg/dl, respectively. Four shipfitters had EP concentrations above the adult normal upper limit of 50microg/dl. No cases of symptomatic lead poisoning were noted. Noise levels adjacent to the rivetting averaged 121 A-weighted decibels (dBA). The OSHA standard for noise is 90dBA. The authors conclude that shipfitters working aboard ship are overexposed to lead and noise. Recommendations include substituting lead based paint with less toxic materials if feasible, avoiding the use of lead/based putty, and establishing a hearing conservation program.
