Research uncovers new threat from harmful algae

Harmful algae could be producing substances which affect reproduction in organisms with similar genetic characteristics as humans according to groundbreaking new research.

Although it has long been recognized by experts that algae produce toxins with harmful effects, this is the first time research has shown that other substances with potential to disrupt the endocrine system – glands which release hormones into the bloodstream to regulate the body – may also be present. Scientists had previously believed those changes were caused by human-made pollutants in water.

It isn’t clear yet whether the chemical, which has yet to be isolated or named, might be affecting other fish species, animals or even humans. “The results do indicate that toxic algal blooms may be producing substances with estrogenic properties which affect hormones.

Note: Harmful algae blooms are encouraged by nitrogen and phosphorous nutrients that enter surface waters by runoff and leaching. Agriculture and home lawn fertilization contribute significant amounts of these nutrients.
