How Does Mercury Get in Fish?
Nearly all seafood contains mercury, a naturally occurring metal buried deep in the Earth’s crust. At room temperature, elemental mercury is quite dangerous; just a few drops can contaminate an entire room. When heated, the element becomes an odorless, colorless gas that can travel great distances before being absorbed into bodies of water. It can also enter lakes, rivers, and oceans when human activities' waste or runoff flows into the surrounding biomes.

Long-term cyanobacterial dynamics from lake sediment DNA in relation to experimental eutrophication, acidification and climate change
Cyanobacterial blooms in aquatic environments have impacted ecosystem health, altered food webs and contributed to substantial regional economic losses. The relative impacts of climate change, eutrophication and other environmental stressors on the formation of cyanobacterial blooms remain unclear as a consequence of the lack of long-term data. The analysis of lake sediment archives can help address such questions.
Great Lakes Take Global Stage
For three days last week the world came together at the United Nations in New York City to discuss ways to place water at the center of decision-making. The UN Water Conference, the first such event in 46 years, was billed as a marquee attraction, a chance to corral public and political attention and train it on the global challenges of too much water, too little water, and water that is too polluted.

On World Water Day, a case for natural infrastructure
The UN 2023 Water Conference in New York, kicking off on World Water Day today, is the first such conference in almost 50 years. But it arrives against a worrying backdrop. Across the globe, we seem to be experiencing the vicissitudes of water, whether it is unprecedented flooding or old and new forms of pollution in lakes and rivers. And thanks to the ever-intensifying impacts of climate change, it doesn’t seem like our fraught relationship with that which sustains us will improve any time soon.
