O Instituto de Pesquisas Ambientais e Tecnológicas – IPAT, da Universidade do Extremo Sul Catarinense – UNESC, realizou em novembro de 2007 o levantamento arqueológico sistemático na área de implantação da Jazida de Argila Araçá, no município de Nova Veneza, sul de Santa Catarina. Como resultado, foram registrados dois sítios arqueológicos inéditos: Sítio Arqueológico Araçá I e Sítio Arqueológico Araçá II, os quais foram objeto deste relatório de pesquisa e de resgate arqueológico. O relatório encaminhado ao IPHAN teve por objetivo incorporar à Memória Nacional as informações obtidas sobre o processo de ocupação humana pré-histórica e histórica regional a partir do estudo e análise dos remanescentes culturais existentes na área em questão, interpretando, à luz da ciência, o seu atrelamento com o ambiente com o qual interagiram. Foram descritos os resultados das atividades de arqueologia preventiva englobando: o resgate dos sítios arqueológicos supracitados, caracterização ambiental,...

Este artigo apresenta uma proposta de sequência arqueológica regional para a Planície Costeira do Extremo Sul Catarinense, com cronologia média entre os 3.500-235 anos AP. Os dados baseiam-se nos resultados dos estudos realizados no projeto de pesquisa Arqueologia Entre Rios: do Urussanga ao Mampituba (AERUM). O setor Norte do projeto AERUM é apresentado no presente artigo como modelo de integração dos dados. Em 286 km2, foram encontrados 53 sítios arqueológicos relacionados a duas fases paleoambientais associadas ao estabelecimento da floresta tropical úmida na região. Existem quatro conjuntos arqueológicos diferenciados: sítios líticos com pontas bifaciais relacionadas à tradição Umbu; sítios concheiros de diferentes cronologias e associados a Sambaquis Plenos (fase 3), Tardios e/ou Jê Meridionais (fase 4) e Guarani (fase 4); e sítios ceramistas com formação de Terra Preta Arqueológica (TPA) associados a grupos Guarani. Os resultados nos permitiram inferir, em uma perspectiva regi...

Coal mining produces amounts of residues containing high levels of chemical elements that contaminate surface and ground water. In the last several decades, constructed wetlands systems have been used to improve the quality of coal mine drainage. Although the impact of coal mining-related toxic substances on fauna community is an important conservation concern, it has not been studied intensively. The objective of this study was to evaluate the possibility of use a microcrustacean (Artemia sp.) and pearl cichlid (Geophagus brasiliensis Quoy & Gaimard, 1824) to assess the toxicity and the genotoxicity, in a constructed wetland at biopolishing acid mine drainage (AMD) previously treated by conventional physical and chemical processes. Effluent samples were collected at four stations along the treatment system: 1 - pH control and precipitation, 2 - second damping pond output, 3 - wetland input and, 4 - wetland output. Acute toxicity analysis using Artemia sp. was performed at AMD conce...

O presente escrito apresenta a experiência da educação patrimonial, realizada no programa de resgate do sítio arqueológico SC-ARA-001 Zulemar Maria de Souza, situado em Balneário Rincão, município do litoral Sul de Santa Catarina. O projeto de salvamento desse sítio, ocorreu no âmbito da prática preventiva de pesquisa arqueológica dentro do processo de licenciamento ambiental de um loteamento no local.

The creation of metal parts via casting uses molds that are generally made from sand and phenolic resin. The waste generated after the casting process is called waste foundry sand (WFS). Depending on the mold composition and the casting process, WFS can contain substances that prevent its direct emission to the environment. In Brazil, this waste is classified according to the Standard ABNT NBR 10004:2004 as a waste Class II (Non-Inert). The recycling of this waste is limited because its characteristics change significantly after use. Although the use (or reuse) of this byproduct in civil construction is a technically feasible alternative, its effects must be evaluated, especially from mechanical and environmental points of view. Thus, the objective of this study is to investigate the effect of the use of WFS in the manufacture of cement artifacts, such as masonry blocks for walls, structural masonry blocks, and paving blocks. Blocks containing different concentrations of WFS (up to ...

An analysis of the archaeofauna remains recovered in the site RS-AS-01 – Sambaqui Praia do Paraíso, located in Arroio do Sal (RS) was made. The Number of Identified Specimens (NISP) was calculated as 14,864 units distributed between molluscs, echinoderms and vertebrates. Mesodesma mactroides (Deshayes, 1854) (yellow clam) was the dominant species in all the stratigraphic levels with a NISP = 9888, followed by Donax hanleyanus (Philippi, 1842) (wedge clam) with a NISP = 1255. In the vertebrates, fish present the highest number of identified pieces, being represented mainly by the species Genidens sp. (Guri sea catfish, NISP = 178), Pogonias chromis (Linnaeus, 1766) (Black drum, NISP = 151), Menticirrhus littoralis (Holbrook, 1847) (Kingcroaker, NISP=33), Micropogonias furnieri (Desmarest, 1823) (Whitemouth croaker, NISP = 29) and other species with lower representativeness: Paralonchurus brasiliensis (Steindachner, 1875) (Banded croaker, NISP = 1), Macrodon sp. (King weakfish, NISP =...

Abstract: In November 2007, the Institute of Environmental and Technological Research (IPAT) of the University of Extremo Sul Catarinense (UNESC) carried out a systematic archaeological survey in the area of implantation of the Araçá clay deposit in the municipality of Nova Veneza in the south of Santa Catarina. As a result, two unpublished archaeological sites were registered: Archaeological Site Araçá I and Araçá II Archaeological Site, which were the object of this research report and archaeological rescue. The report sent to IPHAN aimed to incorporate to the National Memory the information obtained on the process of prehistoric and historical human occupation of the region based on the study and analysis of the cultural remnants existing in the area in question, interpreting, in the light of science, the their relationship with the environment with which they interacted. The results of the activities of preventive archeology were described, including the rescue of the archaeological sites mentioned above, environmental characterization, laboratory analysis, and patrimonial education activities. In this publication will only be presented the aspects inherent to the archaeological rescue and the analysis of the material vestiges coming from them.
