ABSTRACT
The present work indentifies some environmental and health impacts of a municipal solid waste bio-drying plant taking into account the PCDD/F release into the atmosphere, its concentration at ground level and its deposition. Four scenarios are presented for the process air treatment and management: biofilter or regenerative thermal oxidation treatment, at two different heights. A Gaussian dispersion model, AERMOD, was used in order to model the dispersion and deposition of the PCDD/F emissions into the atmosphere. Considerations on health risk, from different exposure pathways are presented using an original approach. The case of biofilter at ground level resulted the most critical, depending on the low dispersion of the pollutants. Suggestions on technical solutions for the optimization of the impact are presented.

Diagnosis of significant disease is a major stressor that may interfere with a patient's quality of life. This case study reports the nursing care of a 29-year-old female marathon runner diagnosed with congenital heart disease. The nursing diagnoses, Alteration in Family Process, Disturbance in Self-Esteem, and Knowledge Deficit are addressed in care plan format.
