Diagnóstico e procedimentos de descarte de reagentes vencidos no laboratório de química da Universidade Estadual do Maranhão: uma análise à luz da legislação ambiental brasileira

Abstract

The improper disposal of expired chemical reagents poses risks to the environment and public health, especially in academic settings where there is a high turnover of chemical substances. This article aims to assess the storage and disposal procedures of expired reagents in the Chemistry Department laboratory at the State University of Maranhão (UEMA), verifying their compliance with current Brazilian environmental legislation. The research employed a qualitative approach and document analysis. The results revealed the absence of a Chemical Waste Management Plan (PGRQ), inadequate storage practices, and disposal without contracts with licensed companies. The analysis, based on Law No. 12.305/2010 and technical standards such as ABNT NBR 14725, showed noncompliance in several aspects. It is concluded that the implementation of corrective measures is urgent, including staff training, standardization of procedures, and partnerships with specialized companies
