Phitoremediation calculator 

Estimations of Pollutant levels based on the experimental SPIRE evolution. The estimates for each pollutant are extrapolated from masurements conducted on polluted lands in the Baia Mare Area. Each row represents a 6month timeframe. The estimated values are calculated up to the moment soils reach the normal levels.
