Port of Santos and CETESB Inspect Truck Emissions

A joint inspection operation was carried out on Tuesday morning (17) by the Environmental Management Department of the Santos Port Authority (APS), the Port Guard, and CETESB, targeting trucks traveling along Avenida Perimetral to monitor pollutant emission levels.

Port Guard agents conducted random stops, allowing CETESB technicians to perform specialized tests: black smoke analysis, colorimetric verification of ARLA 32 (Automotive Liquid Reducing Agent) – an aqueous solution that reduces nitrogen oxide emissions – and particle level measurement in the smoke.

Out of the ten vehicles inspected, two were issued notifications for environmental compliance. Additionally, the Port Guard issued one traffic violation ticket. The initiative was primarily educational, giving notified drivers up to 60 days to bring their vehicles into compliance and avoid environmental fines, which can range from R$2,221.20 to R$17,769.60.

During the operation, the APS Environmental Management Department also distributed educational leaflets. The campaign aims to raise awareness among drivers about the importance of preventive maintenance in reducing black smoke emissions and improving urban air quality.

Health Risks
Beyond environmental damage, black smoke – primarily composed of toxic carbon particles – poses serious health risks. Inhalation can lead to respiratory illnesses, weakened immunity, infections, nausea, headaches, and nervous system toxicity.

Black smoke is emitted by diesel-powered vehicles with engine issues. In other words, it signals incomplete fuel combustion, indicating a need for vehicle maintenance.

This type of emission is often linked to improper carburetor adjustment or a clogged air filter. Therefore, at the first sign of black smoke, drivers should investigate the cause. Air and fuel filters, the efficiency of the fuel injection pump, and potential residue build-up in injectors and cylinders should be checked.
