Year 9 - Science
Darren Clark: Chemistry Teacher
This week, in Science class, 9B has been researching the mercury poisoning disaster in Minamata, Japan in the 1950s. The release of methylmercury into the sea allowed its uptake by seaweed and other organisms, which then passed the mercury onto small fish as they ate their contaminated food supplies. Bigger fish then ate many of the smaller fish and the mercury built up in their flesh even further. The mercury was a cumulative poison and once inside the body, it cannot be excreted. Cats and humans ate the contaminated fish, causing neurological damage, madness, and even death. Here is a selection of the students' posters on the topic.
