High levels of manganese dust have contaminated the air in Nelson Mandela Bay’s harbour and Markman Industrial area, posing a health risk to residents. Exposure levels significantly exceed legal limits, raising concerns about potential health consequences. City officials were aware of the dangerous conditions for months but failed to issue public warnings. The contamination stems from industrial activity and has prompted legal scrutiny regarding the delayed response. Residents are now facing potential health complications and are demanding accountability from local authorities. The situation highlights a potential failure in environmental monitoring and public safety protocols within the Bay. Investigations are underway to determine the full extent of the contamination and implement mitigation strategies.
