Hey everyone! I figured I should go ahead and introduce myself. My name is Allie Tissot and I’m an ecotoxicologist who primarily studies pesticides and microplastics and their effects on marine invertebrates. I’m queer and disabled and very passionate about intersectional environmentalism. 🩵

On Thursday I defended my PhD dissertation and I’m officially Dr. Tissot 🥹💪🏼
Allie is standing in front of a PowerPoint that says “Pesticides as Multiple Stressors to Bivalves and Echinoderms” looking very proud. She’s wearing a floral button up shirt and black pants and a shell lei. A group of people are standing with Allie in a conference room, all smiling. One of them is holding up a laptop with a person on Zoom also smiling.

Absolutely love reading a paper about a pesticide that’s been in use for over a decade that says “we know nothing about its environmental fate.” 😳🤔

These are the glorious stories I’ll be telling my niblings one day, clams are everything.

Hardly new info, but BSky should know:

Warsaw's water quality is monitored by eight clams with magnets attached to their shells. If contamination in the water causes the clams to close, the magnets trigger an alarm and shut off the city's water supply.
Thank you, little guardian molluscs.

A study by the RPTU is the first to examine #pesticide contamination over a year. It shows that substances can be detected not only during the spraying periods in the fields but also throughout the year and in adjacent meadows.

Nepal has taken a significant step in public health by banning the production, sale, and use of three highly hazardous pesticides: paraquat, chlorpyrifos, and phorate. These chemicals have been associated with severe health risks. ipen.org/news/nepal-l...

I do several fundraisers throughout the year to raise money for native plant gardens in Portland. The only way I have found to make it not as awkward to ask for money is to recreate memes. Behold my most recent masterpiece

This is incredible, there are so many issues with Ocean Cleanup and this is an excellent outline!! Thank you!!
rebeccarhelm.bsky.social Rebecca R Helm @rebeccarhelm.bsky.social · Nov 28
"CLEANING" THE OCEAN USING NETS IS A DANGEROUS IDEA.

The Ocean Cleanup is using boats & a net to collect ocean plastic (left). I've circles all the animals trapped in their early prototypes (right).

There are better ways to solve the ocean plastic problem... 🧵
