soil and groundwater, and causes an imbalance of soil nutrients. Among the most common soil pollutants are heavy metals, persistent organic pollutants and emerging pollutants – like pharmaceutical and personal care products. Soil is a finite resource, meaning its loss and degradation is not recoverable within a human lifespan. Soils affect the food we eat, the water we drink, the air we breathe, our health and the health of all organisms on the planet. Without healthy soils we wouldn’t be able to grow our food. In fact, it is estimated that 95 percent of our food is directly or indirectly produced on our soils. The final step, risk characterization, compares this dose with the uptake rate and determines whether or not an adverse effect is likely to occur. Risk assessment procedures can also be used to back calculate a contaminant concentration in soil at which no adverse effects are expected. At times, it may not be possible to remediate to a level compatible with industrial land-use objectives. In such cases, the
