1. Reforested soil under drip irrigation with treated wastewater from poultry slaughterhouse
RESUMO A disposição de efluentes tratados sobre o solo pode ser considerada o principal destino final de águas residuárias no Brasil. Embora possa promover melhorias em relação a alguns atributos do solo, esta prática precisa ser monitorada para garantir que os impactos ambientais não sejam negativos. Assim, objetivou-se com este trabalho avaliar os

2. Sistema de irrigação por capilaridade na produção de porta-enxertos de mudas citricas na fase de sementeira / Irrigation system by capillary action in the citrus rootstocks production in seedings stage
The water and nutrition management in the production of citrus rootstocks in the seedling phase performed by sprinkler systems, manually operated, presents the environmental outcome of water or residual solution disposal from the fertigation. The generated wastewater is generally discarded directly in the soil with the risk to reach the groundwater and conta

3. Fertirrigation with cattle wastewater in Tifton 85 grass and black oat: effects on soil and plants / Fertirrigação de capim-Tifton 85 e aveia preta com águas residuárias de bovinocultura: efeitos no solo e nas plantas
This study was conducted to evaluate the effects from the application of cattle wastewater (ARB) upon both physical and chemical properties of an Eutrophic Red Argisol and on the physiologic, nutritional and yield characteristics of the 85-Tifton grass (Cynodon spp.) and the black oat plant (Avena strigosa Schreb). The experiment was carried out in 20 draina

4. Zn, Ni, Cu, Fe and S in sewage sludge: chemical behaviour, adsorption and treatment proposal / Zn, Ni, Cr, Cu, Fe e S em Iodo de esgoto: comportamento químico, adsorção e proposta de tratamento
The increase of the wastewater treated volume in Brazil has demanded alternatives to the sewage sludge final disposal. At first, agricultural use is one of the viable recommendations since sludge is rich in organic matter, macro and micronutrients necessary to the fertility of the soil. However, it is necessary to consider the environmental impact of some of

5. Nitrogênio e metais pesados em latossolo e eucalipto cinqüenta e cinco meses após a aplicação de biossólido. / Nitrogen and heavy metals in the soil and in eucalyptus grandis leaves 55 months after biosolid application.
Concern regarding environmental quality and human health demands wastewater treatment technology and, with this treatment, sewage sludge is generated. The sewage sludge, after a properly microorganism reduction and physically conditioning, is usually known as biosolid. One of the alternatives for biosolid final disposal is the application in agriculture in a

6. Effects of environmental variables and soil characteristics on virus survival in soil.
Because of the increasing emphasis placed upon land application as a means of wastewater disposal, it is important to evaluate the influences of different factors upon virus survival in soil. The objective of this study was to measure the effects of various environmental variables on virus persistence. Test samples of soil were placed in vials, and the soil

7. Entrainment of Viruses from Septic Tank Leach Fields Through a Shallow, Sandy Soil Aquifer
A study was conducted which focused on movement of naturally occurring human enteroviruses from a subsurface wastewater disposal system through a shallow aquifer. The potential for significant entrainment of virus particles was evidenced by their recovery at down-gradient distances of 67.05 m and from aquifer depths of 18 m. A significant negative correlatio
