Fósforo e chumbo em Mumford (1934)

Industrial diseases naturally flourished in this environment: the use of lead glaze in the potteries, phosphorus in the match-making industry, the failure to use protective masks in the numerous grinding operations, particularly in the cutlery industry, increased to enormous proportions the fatal forms of industrial poisoning or injury: mass consumption of china, matches, and cutlery resulted in a steady destruction of life. As the pace of production increased in certain trades, the dangers to health and safety in the industrial process itself increased: in glass-making, for example, the lungs were overtaxed, in other industries the increased fatigue resulted in careless motions and the maceration of a hand or the amputation of a leg might follow.
