Marine Pollution Calculator
Assess Marine Water Quality (WQI Method)
Based on peer-reviewed Weighted Arithmetic Water Quality Index adapted for marine environments
About the Marine Pollution Calculator
The Marine Pollution Calculator is a scientifically reliable, free online tool that helps you evaluate the pollution level and overall water quality of marine and coastal environments using established Water Quality Index (WQI) methodologies.
Marine Pollution refers to the introduction of harmful substances or contaminants into the ocean, seas, and coastal waters, significantly affecting marine ecosystems, biodiversity, fisheries, and human health. This calculator converts multiple water quality parameters into a single, easy-to-understand index.
Scientific Basis
This tool uses a weighted arithmetic Water Quality Index (WQI) adapted from peer-reviewed methods commonly applied in coastal and marine studies (published in journals like Marine Pollution Bulletin).
The WQI is calculated as: WQI = Σ (Qᵢ × Wᵢ) / Σ Wᵢ, where weights are assigned based on ecological importance (higher for Dissolved Oxygen and nutrients due to eutrophication risks).
Interpretation Table
| WQI Range | Quality Class | Pollution Level |
|---|---|---|
| 90–100 | Excellent | Minimal pollution |
| 70–89 | Good | Low pollution |
| 50–69 | Fair | Moderate pollution |
| 25–49 | Poor | High pollution |
| 0–24 | Very Poor | Severe pollution |
Importance of Marine Pollution Calculator
Oceans cover more than 70% of Earth and provide critical services like climate regulation and oxygen production. However, Marine Pollution from plastics, excess nutrients, oil, and sewage is a growing threat. This tool helps researchers, students, environmental agencies, and coastal managers quickly assess water quality.
