What are two hazardous substances found at the disposal service site in Kalamazoo?

The presence of lead and arsenic at hazardous waste sites is a significant concern due to their detrimental effects on human health and the environment. Lead is a heavy metal that can cause neurological damage, particularly in children, and can lead to a variety of health problems affecting various organ systems. Arsenic, a toxic element commonly found in pesticides and wood preservatives, poses serious health risks, including cancer, skin lesions, and developmental effects.

Both of these substances are frequently monitored in contaminated sites, as they can originate from industrial processes, improper disposal methods, and previous activities in the area. Their identification as hazardous substances highlights the importance of managing and mitigating risks associated with toxic waste to protect public health and preserve the environment.

In contrast, while the other substances listed might also pose risks in different contexts, they either do not specifically match the common hazardous waste profiles found at sites like those in Kalamazoo, or they are less frequently associated with historical waste issues in that area. Thus, lead and arsenic stand out as key contaminants of concern.
