Abstract

Introduction: Informality in the occupational segment devastated many developing economies and is a notable feature of the production of jewelry and fashion jewelry in Limeira city, São Paulo, one of the largest poles of jewelry and fashion jewelry production in Brazil. The production of jewelry and fashion jewelry involves the manipulation of chemical products that may have in their composition potentially toxic elements (PTE) to human health. In Limeira, the production activity occurs inside the households, which means that worker and family members could be exposed to PTE from the occupational activity. Objective: This study investigated occupational exposure to PTE Chromium (Cr), Manganese (Mn), Nickel (Ni), Copper (Cu), and Zinc (Zn), Arsenic (As), Cadmium (Cd), Antimony (Sb), Tin (Sn), Mercury (Hg), and Lead (Pb), household workers and their families included in the production of jewelry and fashion jewelry in Limeira, and discussed the risks identified in the households\' occupational environment assessment versus the current occupational legislation. Methods: This study included 52 families (n = 165 individuals), divided into Exposed group (n = 112) and Control group (n = 53). Blood samples (n = 165) were collected from the workers and their relatives, and air samples from the breathing zone of welders (n = 9). Concentrations of EPTs were determined by ICP-MS. Questionnaires were applied to collect sociodemographic information, details of the workplace conditions and the materials used. The relevant information to compose the occupational environment assessment against the current legal requirements were obtained from these questionnaires. In addition, the principal component analysis (PCA), clusters formation and logistic regression were performed. Results: Cd, Ni, and Cu elements presented higher air concentration than the American occupational guidelines limits. A statistically significant difference was found for the Pb concentration between the exposed and control groups and between the sexes (p <0.05), whereas for Cu and Sb only differences between the sexes were found (p <0.05). Conclusions: Concentrations of EPT found in the air raise concern, since workers\' relatives, including children, are in the same exposure scenario. Inadequate working conditions were observed in the houses, revealing the need to implement urgent public actions to protect these families and the workers. The exposure assessment revealed that workers and family members are at the same risk of exposure as the production of jewelry is carried out without any individual protection and, generally, is performed in the shared environment inside the houses. Public actions and remodeling the productive flow are necessary for the social and health protection of these workers and the families with a focus on improving working conditions and professional regularization.
