Significance of Heavy metal
Heavy metals are toxic elements, often with high density, that pose environmental and health risks. They contaminate water, soil, and air through industrial activities, pesticides, and waste. These pollutants can accumulate in organisms, disrupt ecosystems, and cause health problems like skin damage and neurological issues. Ayurvedic medicine utilizes processed heavy metals, requiring careful detoxification. Monitoring and remediation efforts are essential to mitigate the harmful effects of heavy metals.

Hindu concept of 'Heavy metal'
In Hinduism, heavy metals refer to toxic metallic elements like lead and mercury. They are tested for in Ayurveda formulations to ensure purity and safety, as they can cause harm if not detoxified or within safe limits.
