Decree-Law no. 39/2018, of June 11th, which establishes the legal regime for the prevention and control of atmospheric emissions, obliges the monitoring of stack emissions to air, in order to verify compliance with the emission limit values.
Our Environmental Characterisation Laboratory is prepared to provide an effective response to companies. It has become one of the laboratories with more tests accredited by ISO 17025 for stack emissions monitoring.
Our Laboratory has an accreditation scope with an intermediate flexible description for all these tests. Request here the consultation of the respective list.
