13. Transporte de glifosato pelo escoamento superficial e por lixiviação em um solo agrícola
Glyphosate was determined in runoff and leaching waters in agricultural soil that received an application of active ingredient and was exposed to simulated intensive rain conditions. The concentrations decreased during the simulation period and the concentrations of the runoff were higher than those achieved in the samples of leaching waters. The concentrati

14. Concentrações de randônio nas águas subterrâneas, rochas e solos de Porto Alegre, RS
Many water-supply systems in Brazil utilize groundwaters at least as part of their networks. This is the case of Porto Alegre, capital of Rio Grande do Sul State, whose population is about 1.4 million inhabitants. However, there is little present knowledge in Brazil of the factors affecting Rn presence in the water supplied for end-users, despite the economi

15. Geomedicina: distribuição geográfica dos elementos químicos na água de abastecimento urbano e sua relação com os níveis séricos de elementos-traço na população de Ouro Preto, Minas Gerais, 2006-2007. / Geomedicina: distribuição geográfica dos elementos químicos na água de abastecimento urbano e sua relação com os níveis séricos de elementos-traço na população de Ouro Preto, Minas Gerais, 2006-2007.
As doenças não-transmissíveis representam a principal causa de mortalidade e de incapacitação no mundo e são responsáveis por 59% dos 56,5 milhões de óbitos anuais. Ultimamente vem-se considerando o papel dos elementos-traço, que direta ou indiretamente podem ser fatores de risco ou de proteção para doenças. Em Ouro Preto/MG, apesar de existirem

16. Recent research data on the removal of pharmaceuticals from sewage treatment plants (STP)
Pharmaceutical compounds have been detected in sewage treatment plant (STP) effluents, surface waters and, less frequently, in groundwater and drinking water, all over the world. Different sources are responsible for their appearance in the aquatic environment, however, it is widely accepted that the main sources of this type of pollutant are STP effluents.

18. AVALIAÇÃO DA INFLUÊNCIA DOS COAGULANTES SULFATO DE ALUMÍNIO E CLORETO FÉRRICO NA REMOÇÃO DE TURBIDEZ E COR DA ÁGUA BRUTA E SUA RELAÇÃO COM SÓLIDOS NA GERAÇÃO DE LODO EM ESTAÇÕES DE TRATAMENTO DE ÁGUA
One of the biggest environmental problems faced nowadays by the Water Treatment Stations is the disposal of waste generated in the treatment process steps. The main one, the sludge retained in decanters, has been a reason of qualitative and quantitative characterizing studies, in order to find a suitable solution for your treatment and final destination. The

20. Occurrence and removal of endocrine disruptor compounds in drinking water at Campinas and Sumare, Sao Paulo State, Brazil / Ocorrencia e remoção de disruptores endocrinos em aguas utilizadas para abastecimento publico de Campinas e Sumare - SP
The occurrence of potential endocrine disruptor compounds (EDC) in wastewater treatment plant (WWTP) effluent and surface waters at high concentrations harmful for aquatic life has been an interesting research field due to the probability of these micro pollutants to break through water treatment plant (WTP). The present paper evaluated the occurrence of nat

21. Waters from the past and the reservoirs of Guaraú, Engordador and Cabuçu: a study of Industrial Archaeology / As águas do passado e os reservatórios do Guaraú, Engordador e Cabuçu: um estudo de arqueologia industrial
For this thesis we used Industrial Archeology methodology to analyze the water supply system for the city of São Paulo in the early 20th century, a period during which population density was growing rapidly and what had been a small nucleus of students was clearly destined to become a major metropolis. The most obvious solution, using water from the Tietê

Some organic molecules classified as endocrine disrupters compounds (EDC) have been found in surface waters and attracted attention from the scientific community due to their hability to tamper with the endocrine system of aquatic fauna, hence due to the potential risk they pose to human health. Among the compunds with endocrine properties, the hormones (17&

23. Medidas não convencionais de reservação dágua e controle da poluição hídrica em lotes domiciliares / Unconventional measures of reservoir water and control water pollution in urban lots
This paper aims to analyze the reduction of hydropollution through monitoring non conventional reservation of water applied in urban lots starting from individual and global efficiency integrated to the lot. It also prioritizes the monitoring of both quality and quantity of pollution and the rain flow from its draining. The inclusion of these measurements on

24. Uso da tecnologia de troca iônica no tratamento de águas contaminadas com Nitrato do Aqüífero Dunas-Barreiras, Natal/RN-Brasil
The city of Natal comprises an area of about 170 km (65,63 squares miles). The Dunas-Barreiras Aquifer is the most important reservoir of the coastal basin of RN. It is being responsible for the water supplying of about 70% of the population, however, due to the sewage disposal system by cesspools and drains, it is presently affected in a great extent by nit
