We report a case of occupational asthma and rhinitis caused by inhalation of 1,2-benzisothiazolin-3-one, an additive used as a microbicidal in detergent production, in a 26-year-old man employed in a chemical factory producing detergents. The subject's task consisted of pouring raw materials into the recipient of a machine which mixed the substances. Two months after the beginning of this job the patient complained of rhinitis and asthma at the workplace. The specific challenge test with 1,2-benzisothiazolin-3-one, one of the raw materials to which the subject was exposed, provoked an immediate prolonged asthmatic response and nasal symptoms, whereas exposure to other agents (e.g., alpha-amylase, alcalase or bezalkonium chloride) to which the patient was also exposed at work did not. To our knowledge this is the first case of occupational asthma and rhinitis caused by this compound.
RESUMOEste artigo apresenta a análise da dispensa dos estudos etnoarqueológicos colaborativos no âmbito do licenciamento ambiental da Usina Hidrelétrica Teles Pires e quais as implicações dessa decisão para a proteção do patrimônio arqueológico. Considerando que, na arqueologia, o caráter patrimonial dos conjuntos materiais está intrinsecamente ligado à sua apropriação e fruição pelas comunidades locais -e disso depende a proteção aos contextos arqueológicos -, a decisão expôs os sítios da região aos impactos decorrentes da implantação do empreendimento e abriu um precedente que pode ser desastroso para os povos -e para a conservação do patrimônio culturalafetados por grandes obras de infraestrutura em territórios tradicionalmente ocupados. Palavras-chave: Arqueologia da Bacia do Rio Tapajós; Gestão do Patrimônio Arqueológico; Etnoarqueologia Colaborativa ABSTRACT This article presents an analysis of the waiver of collaborative ethnoarchaeological studies in the environmental licensing of Teles Pires Hydroelectric Dam and what this decision entails for archaeological heritage protection. Considering that, in archaeology, the assignment of heritage values to material assemblages depends on the development and fruition of ideas about artifacts and places by local communities -and that protection to archaeological contexts depends on this -, this decision exposed the archaeological sites of the region to impacts which were caused by the installment of the dam and opened a precedent that could be disastrous for people who are affected by infrastructure works in traditionally occupied territories and the conservation of their cultural heritage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
