GERENCIAMENTO DE SOLUÇÃO DE FORMOL EM LABORATÓRIOS DE ANATOMIA

Abstract

Formaldehyde is of great importance for the fixation of cadavers for anatomy classes, pathology and tanatology studies. The most common solution used for the conservation of corpses and pieces is constituted of formol in tap water, diluted by 8 to 10%. Due to their poisonous characteristics to the alive beings and the environment in general, it is necessary that its management is accomplished. Applying the three basic goals of the management of residues, “reduction, reuse and recycling”, it can be reached an optimization of the formaldehyde utilization. The reduction can be gotten through the quality control of the solution or with a redistribution of pieces in the tanks, when possible. The reuse and the recycling, little spread practices, would be possible with the recovery of drainage solution, with subsequent filtration, clarification, analysis for formaldehyde determination and adjustment of the concentration. The solutions considered useless can be treated in local system, through horizon- tal anaerobic reactor of fixed bed, which demonstrated efficiency of up to 99% in the formaldehyde degradation. Therefore, some simple attitudes, with relatively low cost, can bring economy of financial resources, besides great contributions for the environment.
