Boy Hormones Make Plants Pink!
You might have heard already about endocrine disrupting chemicals, also known as EDCs. They're produced in a range of man-made things, from plastics to personal care products.
The most common one we've heard of is BPA, which is found in plastics- or at least used to be found in plastics. These days, most plastics used for food and drinks contains a little 'BPA FREE' sign, to alleviate public concern.
The concern comes from the fact that, structurally, EDCs look a lot like hormones that are naturally produced in human bodies- think estrogen, testosterone, and a whole lot of others. .
Because of their similarity, it's been suggested that EDCs can interrupt normal hormonal changes in humans- which could lead to nasty stuff like cancer and developmental defects. We want to note that the research is still young in this field, and we're not aware of any conclusive studies in humans (but it's not our speciality- so be sure to hit us up if you know of something concrete). Nonetheless, there's a lot of concern about EDCs, and their ability to get into, and then build up in waterways and soils.
So today on the blog, we're talking about a plant that could be used to detect whether certain land is accumulating EDCs.
The plant turns pink (well, pinky red) when when it comes into contact with EDCs that look like male hormone group known as 'androgens' (testosterone is an example). And for those of you who are keeping score and are really against that whole 'pink is for girls and blue for boys', we feel that we should mention that ANOTHER research group make a plant that gets all kinds of BLUE when it comes into contract with estrogen!
