Heavy Metals
Definition
Heavy metals are metallic elements with high atomic weights that have toxic properties and can accumulate in the environment. Examples include lead, mercury, cadmium, and arsenic. These metals can enter ecosystems through various human activities and pose risks to both environmental and human health.
Analogy
Imagine heavy metals as unwanted guests at a party who refuse to leave. Just like how these unwelcome guests stick around for a long time, heavy metals persist in the environment and can cause harm if they accumulate in organisms' bodies.
