正文(英文) | This year’s finalists in the Stockholm Junior Water Prize are taking on the most challenging water issues in the world, with impressive results. In Bolivia, students are helping their community by teaching low-income families how to purify water using coconut shells. In the Republic of Korea, two students have discovered how to remove heavy metals from water using a substance that comes from algae. Watch the videos below to learn more. Bolivia: Teaching low-income families how to purify water with coconut shells“Seeing people sick from drinking contaminated water, and constantly not being able to afford drinking water, was the main inspiration to do this project,” says Shanne Nashely Montenegro Poma. The two other members of the Bolivian finalist project are Grover Nahum Velasquez Ferrufino and Paulina Irene Velasquez Ferrufino. The group realized that the discarded Brazil nut and coconut shells in the streets of their city could be used for water purification. Switzerland: Evidence of microplastic pollution in the Swiss AlpsAnna Sidonia Marugg is a 19-year-old student who lives in the Engadin, a high Alpine valley region in the eastern Swiss Alps. For her project, she decided to investigate microplastic pollution in her area, since no studies had been done there, possibly because the region seems to be pristine. She found plastic residues at all measuring sites, showing that even seemingly remote regions and sparsely populated areas are affected by microplastic pollution. China: Creating sunscreen using eco-friendly plants oilsMelody Zhang, a student from Guangdong, China, wanted to find a way to make sunscreen that didn’t use synthetic chemical components, such as benzophenone, which research has indicated can damage coral reefs. In her project, the oils were mixed with the physical sunscreen materials (titanium dioxide and zinc oxide powder) to develop a more environmentally friendly sunscreen. This sunscreen effectively blocks the sun while reducing chemical pollution in marine ecosystems. Republic of Korea: Filtering heavy metals using an eco-friendly liquidTwo students from the Republic of Korea have found a safer way to remove heavy metals from wastewater using a substance that comes from algae. “Contemporary methods of toxic heavy metal removal in wastewater involve using a coagulant to attract all of these ions together into a thick sludge,” says Jiung Nam. “However, this method has a few glaring drawbacks.” USA: Improving oil spill cleanups in seawaterAfter an oil spill, the oil spreads into the surrounding seawater through wave action. This forces the oil and water to mix, trapping individual oil particles in the water, and vice versa, resulting in an emulsion – a mixture of liquids that normally don’t mix. Nigeria: Using common plants to treat contaminated water“As a team, we were curious to find a nature-based water treatment solution, considering the fact that chlorine has adverse effects on the environment,” says Garuba Mustapha Ademola, a student living in Lagos, Nigeria. “We decided to do laboratory studies to solve the problem.” |
