Impacts of Activities in Crushing Plant on Environment and Occupational Health of Workers Involved

Abstract With the development of societies there is a growing demand for raw materials for the construction industry, among which the crushed materials existing in the various categories, as set down the specifications of the services of competent bodies. In the long term and as a result of overuse such demands lead to exhaustion of mines and environmental degradation. These materials are produced in crushing plants, which have characteristics of development of its activities, being an aggressive environment for the people involved and, likewise, to the surrounding environment, deteriorating air, water and soil. As for the workers, since the production process, may present in the medium and long term, the emergence of so-called occupational diseases or occupational diseases, these diseases that can lead people to the inability to work and even death. It should be noted that occupational diseases relating to mineral extraction are properly characterized in the literature. In Brazil there's labor and welfare legislation they impose on public and private sectors, the zeal with health workers, and the non-compliance, characterizes the disrespect for life and health of employees, liable to punishment. Likewise, today, there is a growing concern in the world, both in public and private sectors, about the legacy of extractive activities, the need to reassess the system of production and exploitation of mineral resources used to make it sustainable and ensure the existence of future generations, compared to its current unsustainable, and especially with regard to the costs involved. The aim of this study is the importance of the process of comminution in the environment and humans. It will use a literature review, theoretical and descriptive method, as well as statistics from the Ministry of Social Security in Brazil. The reduction of environmental degradation and occupational diseases of workers require more appropriate production techniques as well as major prevention strategies. To do so, you should seek the development of new demands in the area of construction compatible with the reduced use of mineral inputs and labor.

Mitochondrial physiology

As the knowledge base and importance of mitochondrial physiology to evolution, health and disease expands, the necessity for harmonizing the terminology concerning mitochondrial respiratory states and rates has become increasingly apparent. The chemiosmotic theory establishes the mechanism of energy transformation and coupling in oxidative phosphorylation. The unifying concept of the protonmotive force provides the framework for developing a consistent theoretical foundation of mitochondrial physiology and bioenergetics. We follow the latest SI guidelines and those of the International Union of Pure and Applied Chemistry (IUPAC) on terminology in physical chemistry, extended by considerations of open systems and thermodynamics of irreversible processes. The concept-driven constructive terminology incorporates the meaning of each quantity and aligns concepts and symbols with the nomenclature of classical bioenergetics. We endeavour to provide a balanced view of mitochondrial respiratory control and a critical discussion on reporting data of mitochondrial respiration in terms of metabolic flows and fluxes. Uniform standards for evaluation of respiratory states and rates will ultimately contribute to reproducibility between laboratories and thus support the development of data repositories of mitochondrial respiratory function in species, tissues, and cells. Clarity of concept and consistency of nomenclature facilitate effective transdisciplinary communication, education, and ultimately further discovery

Instalações de britagem, condições de trabalho e de processo : uma abordagem de saúde e segurança

A cada dia aumenta a preocupação com relação às condições de exposição ocupacional dos trabalhadores, nos mais diversos setores, tanto em nível da análise dos postos de trabalho quanto das implicações legais decorrentes destas. No presente estudo, sobre as atividades desenvolvidas em instalações de britagem, objetivou-se criar um modelo para analisar, avaliar e propor melhorias para o funcionamento destas instalações, com ênfase na saúde e em segurança dos trabalhadores. Utilizou-se para tal uma metodologia compreendendo: visitas in loco, questionários, análise dos postos de trabalho e da vivência, ou seja, do conhecimento dos envolvidos na operação. Como resultado, obteve-se um modelo que considera os diversos fatores intervenientes na implantação de instalações de britagem (ligando os fatores relacionados aos aspectos: técnicos, jurídicos e ocupacionais). Foram verificadas especificamente possíveis melhorias a serem introduzidas na empresa, bem como, de forma mais ampla, a constatação do descaso ou desconhecimento das empresas quanto aos diversos aspectos que norteiam esta atividade, aspectos psicossociais e comportamentais dos trabalhadores.Day after day we are becoming more and more concerned about workers´ occupational exposition conditions in several sectors from workplace analysis level to their legal implications. In the present study about activities developed in crushing plant facilities we targeted the creation of a model to analyze, assess and propose improvements for these facilities functions focused on health and on workers’ safety. Therefore, we used a methodology which comprehends the following: in loco visits, questionnaires, workplace analysis, its life mode, that is, the knowledge of the ones involved in the operation. As a result we obtained a model which considers the several interfering factors in the implementation of crushing plant facilities (linking factors related to occupational, juridical and technical aspects). We verified specifically possible improvements to be introduced in the company as well as, in a broader scope, we realized a neglect or ignorance of companies regarding the several aspects which rule this activity such as worker´s psychosocial and behavioral aspects
