Phytoremediation Restoring the balance of the environment, by treating environmental pollutants in the soil / air using plants to alter the balance of constituents. This article at The Guardian prompted me to post a thread about Phytoremediation using plants, to see if anyone had any knowledge / experience of working with plants. Recently I was working with someone from the US who was doing a study on Nickel extraction using an Aussie native (which hasn't been published yet, so I'm not sure if I can mention details yet – will check). In the press, carbon dioxide sequesteration is a big topic as it is a relatively simple method of binding carbon into the soil, can be done by all plants and is arguably essential to avoid long-term climate change but the type of plants being grown and the methods used tend to ensure that a net effect is that more CO2 is emitted than carbon sequestered. There are some studies that suggest certain plants (like bamboo, for example) sequester carbon much more quickly than your average tree, but monoculture agriculture definitely has a releasing impact. Bamboo has also been used as to help treat sewerage, having better results when the more wet-tolerant species are used. Here is a small list of plants used, as shown in this Wikipedia entry. So, does anyone know anything about using Australian natives or any other plants to help remediate environmental pollution?
