Plants safely store toxic mercury. Bushfires and climate change bring it back into our environment

Plants can store mercury and keep it from contaminating waterways, air and soils. Unfortunately, that mercury is released when plants burn.

For many, spring is the most agreeable time of year. But for one in six people (around three million Australians), this balmiest of seasons is rendered utterly miserable by allergic rhinitis or hay fever…
