Even in the depths of winter, wildfires have been raging in some U.S. states. There were over 66,000 wildfires across the U.S. last year, and this month’s edition of Periodic Graphics in C&EN magazine takes a look at the products of these large-scale combustion reactions, as well as the effects that these products can have on our health.

Ocean Acidification: “The Other Carbon Dioxide Problem”

Ocean acidification is often referred to as ‘the other carbon dioxide problem’. We’re all quite rightly concerned about the effects that rising atmospheric carbon dioxide levels may have on climate, and the potential consequences of climate change are well documented: more frequent instances of extreme weather, and higher global average temperatures to name but two. Ocean acidification gets comparatively less press, and as such is sometimes misunderstood – but its effects could be equally serious.

Green chemistry is a concept that crops up with increasing frequency; we’ve already discussed it here previously with reference to the Periodic Table’s ‘endangered’ elements, and the recycling rates of metal elements used in mobile phones. But what do we mean by ‘green chemistry’, and what’s required for chemistry to be considered ‘green’? That’s what this post, a collaboration with the University of Toronto’s Green Chemistry Initiative, aims to look at.

Regular readers will spot that today’s post is a bit of a twist on an old post from the site’s archives, which looked at the elements present in a smartphone and the roles that they play. In this updated version, I wanted to highlight which elements in your smartphone will actually get recycled at the end of its lifetime – and which we could be doing a better job at salvaging and re-using!

The Periodic Table’s Endangered Elements

We’re all familiar with the periodic table, but the majority of non-chemists probably aren’t familiar with the everyday uses of some of the many elements it contains. Some elements that many haven’t heard of find uses in technologies or applications we take for granted – but the supplies of these elements on Earth are not infinite. Today’s graphic, in a collaboration with the American Chemical Society’s Green Chemistry Institute, looks at some of the endangered elements in the periodic table, and why we might miss them when they’re gone.
