Crest gold award: Monitoring lead pollution
In this project students will research ways of detecting low concentrations of lead and apply these to test samples from the environment. The objective is to investigate whether lead from petrol still persists at the roadside in order to determine whether there is a lurking legacy of lead.
Students will test whether the samples contain any lead, and if so how much using various reagents to find one that will detect as low as possible concentrations of lead ions, Pb2+. They then test known solutions to decide the lowest concentration of lead ions that can be detected, and research various methods of quantitative analysis for lead ions.
Finally, they need to devise procedures to extract any lead from your soil and plant samples, and perform qualitative analysis on each extract, and quantitative analysis on those that show positive for lead.
