Air Water Pollution — Environmental Science
Air and water quality indices: Air Quality Index, NO2 to AQI conversion, NOx emissions, and biochemical oxygen demand. AQI is a piecewise scale rather than a linear one, so a doubled concentration does not double the index.

About Air Water Pollution Calculators
Air and water quality indices: Air Quality Index, NO2 to AQI conversion, NOx emissions, and biochemical oxygen demand. AQI is a piecewise scale rather than a linear one, so a doubled concentration does not double the index.
Whether you need to solve a one-time problem or verify your own calculations, these free tools cover the most common air water pollution scenarios. All results are computed in your browser — no data is sent to any server.
