Which poisoning agent can seep into water from industrial usage?

Cadmium is a toxic heavy metal that can seep into water sources as a result of industrial activities such as mining, metal plating, and battery manufacturing. When waste products containing cadmium are improperly disposed of, they can leach into the soil and subsequently contaminate groundwater or surface water. Due to its solubility in water, cadmium can easily migrate from the source of contamination, leading to serious health and ecological risks.

Cyanide, while also a toxic substance, is typically associated with specific industrial processes like gold mining and electroplating, and its behavior in water differs. Lead contamination often results from aging plumbing systems or lead-based paints rather than direct industrial discharge. Arsenic is a naturally occurring element in some geological formations but is also associated with specific industrial practices, which may not be as prevalent in general industrial usages compared to cadmium. Thus, cadmium is recognized specifically for its significant potential to infiltrate and contaminate water sources due to industrial activities.
