This systematic review aimed to explore the contributions of Brazilian nursing literature about the use of interviews as a data collection technique in research with children. Articles were searched in the Virtual Health Library, using Health Terminology, between 1998 and 2008. Thirteen articles were selected, whose analysis allowed for reflections on the type of study, investigated age range, ethical considerations, data collection techniques, among others. Data indicated that nurses have used interviews isolated or associated with other techniques. Studies need to present the data collection phase in further detail, so as to indicate ways to improve the interview technique with children in nursing research.

The objectives of our study were to evaluate i) the soil fertility and fractionation of Ba, Cd, Cu, and Zn in the topsoil layer (0-0.20 m depth); and ii) production and concentration and accumulation of Ba, Cd, Cu, and Zn in the components of Eucalyptus trees at 36 months after sewage sludge (SS) application, with or without mineral P fertilizer, compared to mineral fertilization. Application of SS (at N criteria) with P increased soil organic matter and heavy metal concentrations, which were mostly bound to the oxidic and organic matter fractions. SS provided Eucalyptus production and heavy metal concentrations and accumulation in the trunk, branches, and leaves similar to mineral fertilization for high wood production. The application of SS (at N criteria) supplied with P increased soil heavy metal, fertility, and Eucalyptus production, without risk of environmental contamination.
