This article discusses the experience of the map of conflicts related to environmental injustices and health in Brazil and its potential contribution to international movements for environmental justice. Inventories and maps of environmental injustices are important instruments of struggle against injustice and racism, since they increase the visibility of populations, whose lives are threatened. The Brazilian map is published online since 2010 and was an initiative of FIOCRUZ, a public health and academic institution, and the NGO FASE, in cooperation with the Brazilian Network of Environmental Injustice (RBJA), created in 2001. Environmental justice arised in Brazil as a field of reflection and mobilization, and as a rallying point to identify the struggle of several groups and entities, such as rural and urban grassroots movements, indigenous peoples, traditional populations, and peasants affected by different hazards and risks, as well as environmentalists, trade unions, and scientists. Currently, the map has 570 emblematic environmental conflicts in all regions of Brazil. Many economic activities are causing the conflicts such as mining expansion, oil and gas extractions, infrastructure (roads, mega-dams), agribusiness, and pesticide pollution, often with the support of governmental institutions. 相似文献

Recycling of plastic materials is a rapidly developing discipline because of environmental awareness, the need to conserve materials and energy, and the growing demand to increase the production economy. The main problem in plastics recovery and recycling is related to the variety of plastic wastes, even if selective collection occurs. Therefore, plastic materials can be recycled either as mixtures or as single types, separating the different typologies by their physical (size, specific mass, etc.) and/or chemical properties. However, separation of plastics in single typologies by traditional processes and devices is difficult due to their typical low variability in properties. This paper presents a new research development for recycling industry: the Multidune separator. This is a device constructed from a sequence of parallel semi-cylindrical tubes of transparent plastic welded together in a plane. The lower half is shifted laterally and then fixed relative to the upper half. Flow is then induced in the lateral direction normal to the axis of the tubes, creating a main flow channel and two recirculation zones. This apparatus creates a differential transport of particles of low specific mass, near to 1g/cm(3), allowing their separation. The flow field in the Multidune separator is studied via Particle Tracking Velocimetry (PTV). Eulerian analysis of the data is performed to gather information about the fluid-dynamics features established by different hydraulic heads at the inlet of the Multidune. Preliminary tests on monomaterial samples have been performed, varying several operative parameters to determine the best set of values. Therefore, separation tests have been executed on composite samples, obtaining satisfactory results in terms of plastic separation feasibility. 相似文献
