Hello! My name is Yukiha. I am a senior in high school in Okinawa, a small island in Japan, and I am in the International Baccalaureate course.
I am interested in medical engineering and hope to help people with technology in the future. This is my first visit to Stockholm and I am very excited to be a part of SJWP!
In Okinawa, where I live, we have a water tank on top of the roof of each house to be prepared to deal with a water shortage. I think these tanks are only seen in Okinawa, no other prefectures in Japan.
This is what I think is one of the solutions for a sustainable future:Our proposed solution for a sustainable future is Bioremediation using Mangroves, one of the plants that have unique features. These Mangroves are widely distributed in Okinawa, means we are taking advantage of Okinawa's rich natural environment for solving the problems, such as contamination of water.
Amazing purifier: ~Let’s collect mangrove’s fallen leaves for eco-friendly bioremediation of heavy metals~
Kandelia obovata, one of the mangrove species, provides a low-cost solution for recovering heavy metals and improving water quality, which could be useful, especially in developing countries with limited wastewater treatment. In this research, we found that heavy metals such as arsenic, cadmium, and lead accumulate in the fallen leaves of Kandelia obovata. Fallen leaves contain six times more cadmium than young leaves. By collecting these fallen leaves, along withother toxic heavy metals, about 2.01 kg of arsenic and 1.29 kg of cadmium can be recovered per 1 km2 of yellow mangrove forest per year. This method would provide a practical means of addressing heavy metal pollution in water bodies.
