Australia’s own distinctive red soils could play a part in the formation of the stinking swathes of blue-green algae often shovelled off east coast beaches in summer. A team of scientists are taking an in-depth look at how iron reaches water to potentially contribute to the algal blooms, which not only have a foul smell, but also make our eyes sting, cause fish kills and smother seagrass.Iron is known to be a component causative factor for algal blooms but the mechanism by which solid iron in soils becomes soluble and contributes to coastal algae blooms is largely unknown. Geochemistry and hydrology studies to put together enough pieces of the iron jigsaw to form the basis for future research into mitigating its contribution to dangerous algal blooms. The study is funded jointly by the Queensland Department of Primary Industries-Forestry, Forestry Plantations QLD and the Australian Research Council.

This article is about the possibility that iron from soil is a factor in algal blooms. Iron, when it reaches water, helps algal blooms, which cause fish kills and smother seagrass. It is unknown how iron and the soils become soluble and contribute to coastal algal blooms. One way this is possible is the overabundance of a type of bacteria which changes iron into a dissolved state. Another is that different types of plants cause iron to be more soluble. A third is the possibility that groundwater with iron in it interacts in the estuary with the marine environment, causing chemical reactions that make iron soluble.

1)The iron in the soil gives the soil its distincitive color.

2)One type of bacteria in our waterways changes iron into a dissolved state.

3)People have studied iron levels in native vegitations and pine platations.

4)Their research is centered on the catchment of Poona Creek on the Fraser Coast.

5)Soil rich with iron make fish sick

1.)There are two types of bacteria in water that feed on iron.

2.)One type of bacteria in our waterways changes iron into a dissolved state.

3.)Another type of bacteria oxidises the iron and turns it back into a insoluble form which can settle on the bottom of a creek.

4.)Iron gives our iron-rich soil its red colour, reaches water to potentially contribute to the algal blooms, which not only have a foul smell, but also make our eyes sting, cause fish kills and smother seagrass.

5.)Iron is known to be a component causative factor for algal blooms but the mechanism by which solid iron in soils becomes soluble and contributes to coastal algae blooms is largely unknown.
