Investigation of particulate matter and toxic metals in the Saldanha Bay Municipality

Written By laura owings

This report is a summary of the work performed by Dr Heleen Vos, Dr Janine Colling, M. Isabella Braithwaite, Ms Kereemang Gaoaaga, and Prof Susanne Fietz at Stellenbosch University.

The research was conducted in collaboration with Ms. René Toesie from the Municipality of Saldanha Bay and was supported by several citizens of the Municipality of Saldanha Bay who allowed the installation of samplers and sensors on their property. The work aims investigate the potential sources and transport mechanisms of particulate matter and potentially toxic metals1 in the Saldanha Bay Municipality area to provide recommendations for possible mitigation strategies.

Key messages:

  • Air pollution, especially suspended particles (particulate matter), is a global challenge threatening human health.

  • Particulate matter can have natural and anthropogenic origins, such as industry, combustion, transportation, and mining.

  • Fine particles, such as PM2.5, are more commonly associated with anthropogenic activities and arguably more harmful for human health because it can penetrate deeper into the respiratory system. These fine particles generally also have higher toxic metal content.
