Agencies are replacing mercury contactors due to what type of concerns?

Agencies are replacing mercury contactors primarily due to environmental concerns. Mercury is a toxic heavy metal that poses significant health risks to humans and wildlife. Its use is heavily regulated, and there are comprehensive efforts to reduce mercury pollution in various applications, including traffic signal systems. The disposal of mercury-containing devices can lead to contamination of soil and water bodies, aggravating environmental issues. By phasing out mercury contactors, agencies are aligning with environmental standards and regulations aimed at protecting ecosystems and public health. Transitioning to safer alternatives not only mitigates these environmental risks but also reflects a growing awareness and responsibility toward sustainability and ecological impacts in urban planning and infrastructure.
