Laurentian SETACers! If you are at SETAC-North America this week, come meet up with us at the SETAC Groups area during Tuesday's afternoon poster session.

Nearly 1 million pounds of vinyl chloride were on this train. Now, the EPA has confirmed it's entered the Ohio River basin which is home to 25 million people.

This is one of the deadliest environmental emergencies in decades and no one is talking about it.

[Laurentian SETAC @LaurentianSETAC]

Tune in today for Chemistry & Lab Toxicology live discussions (starting at 1 pm), followed by a social networking event for students (6:15 pm), and the AGM social hosted by our amazing sponsor @gather_town (7 pm). You won’t want to miss it!

Spilling oil toxicity mechanism facts about birds: We can all picture the sad looking birds covered in oil after a spill, but what about the effects we can’t see with our eyes?
Check out this egg-cellent thread🧵: (1/9) #LaurentianPrairieResearch @LaurentianSETAC @SETAC_PNC

Nonlethal effects include reduced brood size/fecundity in zooplankton, and altered swimming, feeding, and predation behaviour with various fish. This made us wonder... (6/18)

[heather j @jovheather]

For humans, that’s great. It means I only take 1 💊 in the morning instead of 20. For fish and invertebrates, it means that the concentrations we see dissolved in surface waters – even though they’re lower than what we might take – are high enough for them to take up. (4/18)

Here’s the thing about antidepressants: they work. They are lifelines for millions of people across the world. And.. they are efficiently designed – meaning they are effective even at low doses. (3/18)

Missed my poster at @SETAC_world? Want to know more about the work we’re doing at @IISD_ELA on chronic venlafaxine exposure? You’ve come to the right thread! 🧵#LaurentianPrairieResearch @SETAC_PNC (1/18)

[Moira (she/her) @moira_ijzerman]

Hi everyone! My names Moira and I’m a PhD student at @UofG_SES. I’m working on a method to use biofilms as a pesticide monitoring tool in aquatic ecosystems. @LaurentianSETAC #LaurentianPrairieResearch🧵 (1/7)

[Laurentian SETAC @LaurentianSETAC]

And here we are! L-SETAC & PNC's Joint virtual AGM, under the them "Together Apart".
Join us all week!

STUDENTS: Can’t wait to see you at 6 pm for “Networking with Informational Interviews: A Hands-on Workshop”, led by Dr. Verena Sesin.

[Dr. Rebecca Rooney @girls_can]

Oh NO! This is a terrible outcome. HOW?!!

My Senate speech on the Emergencies Act was too long to upload to Twitter. So here’s a link to the speech, posted to Facebook. We’ll post the speech to YouTube tomorrow AM and I’ll share it again. But for now - you can watch it here. #SenCa #cdnpoli https://t.co/uhjgerelZ3

Just over 5 years after I had the initial idea, our global monitoring study of pharmaceuticals in rivers is out!! It presents a unique dataset on pharmaceutical pollution across 104 countries - ://www.pnas.org/content/119/8/e2113947119

Today's fish is the Candy Darter (Etheostoma osburni)! These little fish's range has been restricted, and it faces threats from hybridization and human disturbance of rivers, as it requires clear, unsilted water to breed :(

Premier Doug Ford is driving his vehicle while doing a FaceTime with CP24.

You’d think the Premier would know some of the distracting driving laws…

Can’t say @BKatzenback or myself loved being filmed, but #CTVkitchener did a great job covering the new WATER facility at @WaterlooBio and the work we plan on doing studying #climatechange impacts and #pathogens in fish and amphibian species https://t.co/vjhWipBQah
