The aim of the experiment was to investigate which soil absorbs the greatest amount of pollutants in the environment using the mediums: white sand, potting mix and soil from a garden. The pollutants involved in the experiment were, vegetable oil, petrol and engine coolant. The potting mix, which has the greatest porosity, absorbed the most amount of the pollutant and the hypothesis was therefore supported.
like EVERYTHINGELSE i've done.. simple and sweet!
ABSTRACT:
Soil pollution is widespread in all areas and is often the outcome of years of planned or unintentional emission of pollutants (SAFER SOLUTIONS, N.D). The aim of the experiment was to investigate which soil absorbs the greatest amount of pollutants in the environment using the mediums: white sand, potting mix and soil from a garden. The pollutants involved in the experiment were, vegetable oil, petrol and engine coolant. The hypothesis is that a soil type with more porosity will have absorbed more of the pollutants. The potting mix, which has the greatest porosity, absorbed the most amount of the pollutant and the hypothesis was therefore supported.
