The management of health, safety, and environmental (HSE) aspects during production, manipulation, storage, incorporation, and disposal of carbon nanomaterials is the key factor for the development of a safe-by-design work based on nanotechnology. The almost endless possibility of functionalization, chemical interaction, and addition of nanomaterials into new products implies a new management approach of HSE. Low amount of reliable toxicity and ecotoxicity data of nanomaterials and nanomaterial composites is available. As complete exposure/ release assessments are a challenging task, recommendation for control measurements is still based on the precautionary point of view. There is an incomplete understanding of environmental fate-and time-related exposure, and of consumer-and worker-related risks and hazards. Control banding and risk evaluation matrix tools can be used to mitigate labor and environment impacts of carbon nanomaterials. This chapter presents new tools and methodologies for exposure assessment and risk evaluation of hazards used on HSE management system of carbon nanomaterials.
RESUMO: : O SMR e Q-slope são métodos empíricos desenvolvidos para classificar maciços rochosos para escavação de taludes. Tais métodos abordam a estabilidade dos taludes rochoso de formas diferentes. Assim este estudo teve como objetivo verificar a existência de correlação entre estes métodos. Para tanto, os dados utilizados foram obtidos por meio de scanlines em taludes localizados no Bairro Jardim Trujillo em Sorocaba e na mina do Vau Novo, localizada no munícipio de Santana do Parnaíba, ambos no estado de São Paulo. Utilizando o coeficiente de correlação (R 2 ) como ferramenta, observou-se que os métodos de classificação se correlacionam de forma adequada ao se relacionar o índice SMR com a razão do ângulo β, obtida pelo método Q-slope, pelo ângulo real do talude.
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.
