3. Monitoramento de cistos de Giardia spp. e oocistos de Cryptosporidium spp. em um manancial eutrofizado com presença de florações de cianobactérias : represa de Salto Grande, Americana-SP / Monitoring of Giardia cysts and Cryptosporidium oocysts in an eutrophic waershed with presence of cyanobacteria blooms : Salto Grande, Reservoir, Americana-SP, Brazil
O reservatório de Salto Grande é formado pelo rio Atibaia que contribui para a poluição das águas superficiais desta represa, devido ao despejo de efluentes domésticos. Além disso, o desenvolvimento urbano, a industrialização e atividade agrícola nas proximidades da represa, também proporcionam alteração da qualidade das águas deste manancial.

4. Desenvolvimento e aplicação de técnicas miniaturizadas de preparo de amostras para análises ambientais via GC-MS / Development and application of miniaturized sample preparation techniques for environmental analysis via GC-MS
This study describes the development and application of different miniaturized sample preparation techniques for environmental analysis via gas chromatography and mass spectrometry (GC-MS). Among those techniques, the Solid Phase Extraction (SPE) was applied to the analysis of plant growth regulator, called paclobutrazol (PBZ), in soil samples. A method was

5. Methods studies : calcium carbonate floculation and adptation of membrane filtration and immunomagnetic separation techniques for Cryptosporidium and Giardia detection in water samples / Estudo dos metodos : floculação em carbonato de calcio e adaptação das tecnicas de filtração em membrana e separação imunomagnetica para a detecção de Cryptosporidium e Giardia em amostras hidricas
The waterborne transmission route of giardiosis and criptosporidiosis has been considered the major one, causing the occurrence of several gastroenteritis outbreaks in several countries in the last years. Looking to this panorama, was published in Brazil the Governmental Decree 518/04 (Health Department), that recommends the research of these protozoa in wat

6. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

7. 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

8. Uso de invertebrados bentônicos na avaliação da qualidade da água da bacia do Alto Atibaia (SP) / Use of benthic invertebrate in water quality assessment of Atibaia river basin (São Paulo, State)
Due to importance of the use of bioindicators to assess environmental quality and the advantages of employing benthic macroinvertebrates for this purpose, these organisms were used to assess the water quality of the Atibaia river basin (SP) in eight sites: 3 in the Atibainha river, 3 in the Cachoeira river, and 2 in the Atibaia river. Channel, depositional m

9. Occurrence of endocrine disrupters and pharmaceuticals products in surface waters in the Atibaia river basin / Ocorrencia de interferentes endocrinos e produtos farmaceuticos nas aguas superficiais da bacia do rio Atibaia
Numerous organic compounds called endocrine disruptors have been found at low levels in surface waters. Several compounds such as hormones (17b-estradiol, 17a-ethinylestradiol, estrone, progesterone and levonorgestrel), phthalates (diethylphthalate and dibutylphthalate), surfactants (4-octylphenol and 4-nonylphenol), bisphenol A, among others are included in

10. Um novo índice de qualidade das águas para proteção da vida aquática aplicado ao Rio Atibaia, região de Campinas/Paulínia-SP
In this paper a water quality index is developed to subsidize management actions in the Atibaia River for upon protection of aquatic organisms. This index is composed of two measurable environmental parameters normaly, ammonia and dissolved oxygen, the latter representing the contribution of organic matter. Concentrations of these two variables were normaliz

11. Investigação sobre a emissão e caracterização dos hicrocarbonetos policiclicos aromaticos (HPA) na bacia do rio Atibaia / Investigation on emissions and characterization of polycyclic aromatic hydrocarbons (PAHs) in the Atibaia river basin
In this work, 18 PAHs were analyzed in sediments as well as in the suspended particulated matter in seven sampling points distributed along the Atibaia river basin during four sampling campaigns. Results show higher PAHs concentration during the dry season. The most impacted sampling point was at the Campinas potable water withdraw station with PAHs total co

12. Avaliação da qualidade ambiental, utilizando invertebrados bentônicos, nos rios Atibaia, Atibainha e Cachoeira, SP / Envitonmental quality assessment using benthic invertebrates: Atibaia, Atibainha, and Cahoeira rivers, São Paulo, Brazil
Immature insects of the Orders Ephemeroptera, Plecoptera and Trichoptera (EPT) are considered sensible members of the macrobenthic community in lotic ecosystems. Accordingly, they are often used as indicators of environmental disturbances as pollution. Eight sampling sites were established along the rivers Atibainha, Cachoeira and Atibaia of Piracicaba river
