What harm can this contaminant do?
You’ll come across the pollutant benzene while refuelling your car. Most of it is man-made and if you’re around industrial activities or vehicles you’ll likely find it. Petrol spills, storage leaks and wastewater can cause entry into drinking water. Some bottled waters and soft drinks include sodium benzoate as an ingredient.
