This study investigates how different crops absorb heavy metals, aiming to identify those best suited for cultivation in polluted environments. It also examines which growth conditions affect heavy metal uptake and which parts of the plant accumulate the most. The project focuses on developing practical, easy-to-implement guidelines to ensure food safety, when polluted water is used for irrigation – especially in countries where access to clean water is limited.
Through our high school’s partnership with a school in Bagamoyo, Tanzania, we became aware of heavy metal contamination in soil and water. This inspired us to explore how to improve food safety and develop practical, low-cost solutions that local communities can easily implement, even in areas with polluted water sources.
