1. Marcadores orgânicos moleculares como ferramentas no monitoramento ambiental: Avaliação da distribuição de Alquilbenzeno Lineares (LABs) em organismos e sedimentos, como indicativo de exposição ao esgoto em áreas costeiras / Organic molecular markers as tools in environmental monitoring: Evaluation of Linear Alkylbenzene (LABs) distribution in organisms and sediments, as indicative of exposure to sewage in coastal areas
The sewage disposal in coastal areas can cause impacts to marine life, altering the balance of the ecosystem and biodiversity and causing serious diseases in humans. In this study, the concentration of a set of molecular markers for the introduction of organic sewage into the marine environment: linear alkylbenzene (LAB), in samples of sediment, oysters (Cra

2. Impactos Socioambientais no EstuÃrio do Rio Jaguaribe: o Caso da Cidade de Aracati-Ce. / Social and Environmental Impacts on River Estuary Jaguaribe: If the City Aracati-Ce.
The Jaguaribe River was fundamental to the development of the city of Aracati. However, during recent decades a degradation of the fluvial and marine ecosystems caused by several environmental impacts has been perceived. Analyzing the social and environmental impacts at the estuary of the Jaguaribe River, highlighting the process of urban expansion from 1980

4. Efeitos da dragagem sobre a qualidade de sedimentos contaminados do canal do porto de Santos : biodisponibilidade e toxicidade de metais e compostos orgânicos persistentes / Effects of dredging on the quality of contaminated Sediments from the channel of the port of santos: Bioavailability and toxicity of metals and persistent Organic compounds
Contaminated sediments is a worldwide problem, and mobilization of contaminants is one of the most critical issue in environmental risk assessment when dredging projects are concerned. Considering this, we decided to investigate if and how toxic metals and persistent organic compounds such as PAH and PCB are mobilized during dredging operations in the Port o

5. "Estudo hidrogeoquímico, sedimentológico e de foraminíferos em áreas da Baixada Santista, SP, submetidas a disposição oceânica de esgotos" / "Study hydrogeochemical, sedimentological and of foraminifers in regions of the Baixada Santista, SP, submitted to oceanic sewage disposal"
O presente estudo analisou a influência do emissário submarino de esgoto sobre as associações de foraminíferos, regionalmente (macroescala) e localmente (microescala), na Enseada do Guarujá e Baía de Santos. Foram analisadas, em macroescala, 26 amostras coletadas na Enseada do Guarujá e 24 na Baía de Santos. As amostras foram obtidas no inverno de 1

6. "Marcadores orgânicos geoquímicos em testemunhos de sedimento do Sistema Estuarino de Santos e São Vicente, SP: um registro histórico da introdução de hidrocarbonetos no ambiente marinho" / Geochemical organic markers in sediment cores of the Santos-São Vicente Estuary, SP: a historical register of the introduction of hydrocarbons in the marine environment
Estuarine areas are environments between land and ocean, where human activities are intensively developed. The Santos and São Vicente Estuary, located on the central portion of the coast of São Paulo state, has one of the most important industrial areas of Brazil. The increasing of urbanization and industrialization near the margins of Estuary, in the 50

7. Palaeoparasitology in Japan: discovery of toilet features
The development of palaeoparasitology in Japan has occurred in recent decades. Despite the fact that archaeology in Japan has been slow to develop techniques for excavating ancient toilets, important information about the development of sanitation has been derived from the analysis of a few sites. This shows that the earliest people had very simple methods o

8. Effects of Pharmaceutical Wastes on Microbial Populations in Surface Waters at the Puerto Rico Dump Site in the Atlantic Ocean
A series of cruises during 1979 and 1980 to the pharmaceutical dump site located 64 km north of Arecibo, Puerto Rico, in the Atlantic Ocean, was carried out to evaluate effects of wastes on the ecology of the microflora of surface waters of the dump site. In addition to bacteriological monitoring of the waste plume created by the release of wastes from the d

9. Human pathogenic viruses at sewage sludge disposal sites in the Middle Atlantic region.
Human enteric viruses were detected in samples of water, crabs, and bottom sediments obtained from two sewage sludge disposal sites in the Atlantic Ocean. Viruses were isolated from sediments 17 months after the cessation of sludge dumping. These findings indicate that, under natural conditions, viruses can survive for a long period of time in the marine env

10. Distribution of Clostridium perfringens and Fecal Sterols in a Benthic Coastal Marine Environment Influenced by the Sewage Outfall from McMurdo Station, Antarctica†
The spatial distribution, movement, and impact of the untreated wastewater outfall from McMurdo Station, Antarctica, were investigated under early austral summer conditions. The benthic environment was examined to determine the distribution of Clostridium perfringens in sediment cores and the intestinal contents of native invertebrates and fish along a trans

11. Occurrence of fecal indicator bacteria in surface waters and the subsurface aquifer in Key Largo, Florida.
Sewage waste disposal facilities in the Florida Keys include septic tanks and individual package plants in place of municipal collection facilities in most locations. In Key Largo, both facilities discharge into the extremely porous Key Largo limestone. To determine whether there was potential contamination of the subsurface aquifer and nearby coastal surfac

12. Bacteria associated with crabs from cold waters with emphasis on the occurrence of potential human pathogens.
A diverse array of bacterial species, including several potential human pathogens, was isolated from edible crabs collected in cold waters. Crabs collected near Kodiak Island, Alaska, contained higher levels of bacteria than crabs collected away from regions of human habitation. The bacteria associated with the crabs collected near Kodiak included Yersinia e
