#IndustrialHygiene, specifically, relative #Historical #toxic exposures. Plumbum, #lead. The Romans used in for amphora to store wine, so they drank lead salts. For centuries, it was used in water delivery as well as waste pipes. Pigments in cosmetics, in house and furniture paint. Anti-knock for #gasoline. A few generations back, gasoline was used for home #DryCleaning.I wonder how much lead that left in the clothing? The fumes? Well, oil or gas lights, gas/wood/coal cooking--plenty of VOCs.
