Which of the following best describes inorganic pollution?

Inorganic pollution primarily refers to the contamination of water sources by inorganic substances, which include minerals and metals rather than organic materials such as plant and animal matter. Heavy metals like lead, mercury, arsenic, and cadmium are prominent examples of inorganic pollutants, as they can have significant toxic effects on both environmental and human health. These metals are typically sourced from industrial processes, waste discharges, and certain agricultural practices.

Other types of pollution mentioned, such as those caused by organic matter, thermal discharges, or bacterial growth, are not classified as inorganic pollution, as they involve organic substances or biological factors rather than inorganic compounds. Understanding the distinction between organic and inorganic pollution is crucial for proper water quality management and pollution remediation efforts.
