When the environmental conditions are right, blue-green algae (which are actually blue-green bacteria) can blossom into harmful algal blooms. These blooms can release all sorts of deadly poisons into the environment. In this episode, SOC’s Sophia Cai explains how human health could be at risk, with help from SOC’s structure-drawing extraordinaire, Lauren Wolf.

I love learning about random chemicals, their effects, and their active groups.
The picture of the frog shows it in duckweed, I believe, not algae. Duckweed is a flowering aquatic plant often confused with algae.
The photo with the frog is a tiny flowering plant called duckweed (Lemna). This could confuse people as it is harmless to humans but can be annoying on garden ponds. It is really difficult to get a positive identification of blue- green algae. I was fishing at a small lake in Yorkshire (England) recently, and the surface was covered in algae (as it often is) due to eutrophication caused by agricultural runoff. As it was a pale green algae, I presumed that it was not the toxic blue-green algae. I had to handle it, as it kept clogging my lines as the wind kept moving it around the lake. It usually starts off as tiny dark green strands in early summer. As I have felt a bit unwell over the last two weeks (upset stomach), I am beginning to wonder whether the algae is a toxic species. Is there a way of being certain of the species and whether it is safe (other than sending a sample to a laboratory)?
can i know if how the bactiria do on our self and body
How is BGA controlled when there a huge bloom in a water reservoir for example?
I just read elsewhere that algae can help with carbon sequestration as some kinds emit huge amounts of oxygen. So it algae a good guy or a bad guy in the global warming picture?
Other than Nitrogen, Phosphorous, Light intensity, Temperature what can be more toxin producing or stress parameters on cyanobacteria ?
Legendary structure drawing ability 🖖🏼
Wow, great explanation Sophia! HABs can sneak up on those who don't know what to watch out for...cyanotoxin and saxatoxin... gnarly stuff!
Best science and most underrated channel on RUclips! Keep it up guys !
With the high nitrogen and phosphorus in algae, I wonder what work has been done on the idea of skimming this algae and using it for furtilizer? I assume once decomposition begins, the various toxins degrade.
I love chemical names and chemical structure diagrams.
I have cyanobacteria in my fish tank at home. i always have cuts on my hands due to dryness and allergy. Is the cyanobacteria dangerous to me as I have cuts on my hands and touch the water? .
What can one do if they have this one in human blood Aphanizomenon ovalisporum (light micrograph)
Thanks for video
A question: how can I tell the difference between algae and Cyanobacteria? Are there any common visual cues?
Can the algea be harmful if you cant see it while Swimming?
Her drawing skill is great!
Is this that same like in Salem Oregon
these algal blooms; do they release poisons or toxins in the air if you say step on one? if so, will it suddenly kill you? the reason i ask one of my good friends passed away at a lake in corinth ky, he made it only 10ft in the lake and all of a sudden stopped breathing and died somehow i feel this may have been a cause but i just wondered if you had more information about that....he also turned blue and purple, could that be the algal blooms or do you believe something else could've caused this?
