In 2014, a large oil spill devastated the world largest mangrove forrest, the 2014 Sundarbans oil spill. The emotional impact on Cesar Jung-Harada students triggered the desire to prototype this fluorospectrometer largely based on the Public Lab designs.
Fluorospectrometry is a well-known technology but here, we tried to make our own low-cost version and see if that affordable DIY instrument could be calibrated to produce repeatable and accurate measures from household products.
The results were encouraging and we sent our oil contamination sensor to our friends in Dhaka.
Oil spills happen all around the world all the time. Citizens need to monitor and understand their environment. In Hong Kong we also had an oil spill in Lamma Island in 2013. See videos of the Lamma Oil Spill, walking in the rocks, cleaning up.
