|Oysters in lab|
While conducting my research on cadmium and its effects on the sediments I came across an interesting article, “Rising temperatures toxic for sea-dwellers.” The article was about a study that was conducted to measure the effects that global climate change will have on organism’s sensitivity to toxins in the water. Though it doesn’t necessarily have to do with sediments there has been a lot of talk about global climate change lately in class and I thought it was really neat to see the effects global climate change will have on cadmium toxicity. The researcher’s experiment consisted of measuring the metabolic rates and the ability to synthesis ATP (the main energy in a cell) of eastern oysters at different temperatures in both clean water as well as water that was polluted with the heavy metal cadmium. What the researchers found was that during increased temperatures the toxic effects of the cadmium also increased in the oysters by limiting their ability to synthesis ATP making the organism less likely to survive due to an energy deficit. If that isn’t bad enough the increase in temperatures also increase the speed of metal intake of the organism leading to an increase of accumulation of the toxin in the organism.
