Oxygen oases in the oceans 500 million years before oxygenation of the atmosphere
2.9-billion-year-old marine sedimentary rocks from Canada’s Red Lake region reveal areas of oxygen accumulation at a time when the oceans were globally anoxic and iron-rich. These oxygen oases played a […]

Assessing air quality with plants: yes, but for which elements?
Epiphytic plants, which absorb their nutrients exclusively from the air, are good indicators of the chemical composition of atmospheric particles and are often used in the literature as diagnostic tools. […]
