In a prospective study, 18 chimney sweeps aged between 21 and 57 years were examined with the aim of detecting the presence of heavy metals in the blood and urine, and identifying cardiopulmonary diseases. Elevated concentrations of cadmium were found in three cases, and of lead in two cases, the concentrations being such that damage to health could not be excluded. None of the chimney sweeps showed any signs of bronchial hyper-reactivity or coronary heart disease. With respect to risk factors for coronary heart disease, elevated cholesterol and/or triglyceride levels were observed in 7/16 patients. These figures are compatible with the average figures for the Austrian population at large.

Traditional methods for measuring chemical exposure have challenges in terms of obtaining sufficient data; therefore, improved methods for better assessing occupational exposure are needed. One possible approach to mitigate these challenges is to use self-monitoring methods such as sensors, diaries, or biomarkers. In the present study, a self-monitored method for measuring soot exposure, which included real-time air monitoring, a work diary, and the collection of urine samples, was evaluated.

Exposure to polycyclic aromatic hydrocarbons (PAHs) of high molecular weight from chimney soot can cause cancer among chimney sweepers. These sweepers may also be exposed to high concentrations of nanosized particles, which can cause significant inflammatory responses due to their relatively greater surface area per mass. In this study, the authors aimed to assess the exposure profiles of airborne personal exposure to gaseous and particulate PAHs, and real-time samples of the particle number concentrations (PNCs), particle sizes, and lung-deposited surface areas (LDSAs), for chimney sweepers in Norway.

The 18th century was linked to a type of skin cancer with a clear professional etiology: scrotal carcinoma in chimney sweeps. Sir Percival Pott had the merit of identifying the disease as a malignant and inexorable process and of describing its natural evolution. In this article, we present some historical aspects of such description, as well as the working environment of the main individuals affected by this cancer, who were children carrying out the work of chimney sweeps.

Physicians remember the name of the surgeon Percivall Pott (1713-1788) because of the eponym "Pott's disease", described as "paralysis in the lower limbs, which is often accompanied by curvature of the spine". Pott's writings on surgical subjects are far vaster. For example, he described the fracture-dislocation of the ankle, or Pott's fracture, and determined the cause of scrotum cancer in chimney sweeps.

Observations of the incidence of tumors among chimney sweeps in the eighteenth century and later experiments with coal tars provided early evidence that carcinogens in the environment can promote cancer. Subsequent studies of individuals exposed to radiation, work on fly genetics, and the discovery that DNA was the genetic material led to the idea that these carcinogens act by inducing mutations in DNA that change the behavior of cells and ultimately cause cancer. In this excerpt from his forthcoming book, Joe Lipsick looks back at how the concepts of mutagenesis and carcinogenesis emerged, how these converged with development of the Ames test, and how biochemistry and crystallography ultimately revealed the underlying molecular basis.
