Other plastics, such as acrylic, nylon, polycarbonate, and polylactic acid (a bioplastic), and multilayer combinations of different plastics
This week in lab I have been reading the article that Matt gave me called “ Laboratory Methods for the analysis of micro plastics in the marine environment: Recommendations for quantifying synthetic particles in waters and sediments” . The article and program I will be working with is WAESO. The article mentions what in specific are micro plastics and why they have been a health concern for sea creatures.

“Develop protocol for extraction of micro plastics from soil and sediment”. Is our goal for this lab.

This week I have been researching different types of plastics, and have been collecting the different types of plastic that I will be needing in order to shred them into small particles.

This week in Lab the only plastic I am waiting to weigh is SPI6. The reason this one is taking longer is because when I rinsed it with DI water it soaked some of the water up which meant I had to leave it in longer to dry out than the other plastics. Then when it was completely done drying I put the hydrogen peroxide to get rid of any nature products that could have been left behind. Right now they are still drying, until they are completely dry is when I will then be weighing it and that will conclude my last sample for weighing. After that I will finally have all data to analyze. I will be determining which extraction method/ water solution works best on microplastics. I will also be determining plastic loss in all three different solutions and see if there was a was to better change the protocol that the NOAA developed for extraction of microplastics from sediments.

So the picture above shows the location of where I got the sample water though, though I regret not getting the coordinates of the exact location I took the water sample from because Tempe Town Lake is pretty big. This weekend while also this weekend I went to Tempe Town Lake again but the only difference was that there were a lot of dead fish just floating around and some even on shore. Which got me thinking if we might something new in the microplastic bacteria growth. There was also a report during 2014 where there was an extreme growth of E. Coli in Tempe Town Lake Water. “ Tempe has received water samples from Town Lake taken Thursday morning that show E. coli bacteria more than 10 times higher than the state's allowable” (Tempe Town Lake 'unsafe' water sample threatens race). I missed another great opportunity and forgot to take pictures of the dead fish. So perhaps maybe this week I will go again and take pictures.

“It's not what you achieve, it's what you overcome. That's what defines your career." —Carlton Fisk Growing up in a strict Hispanic Household my siblings and I were always told that we needed to become doctors when we grew up. That if we were doctors we would have a stable bright future. So of course in High School I would tell everyone that I would grow up to be a Doctor. I didn’t know what kind of doctor, I just knew I was going to be a doctor. Once I graduated High School and enrolled at Phoenix College, I told my advisor, “I want to be on the path that will make me a doctor”. So for 2 years I was taking all my pre-requisites to be a doctor. It wasn’t until my second year at Phoenix College and almost close to graduation that I wanted to be an ophthalmologist. So I looked online and started studying for my Optometry Entrance Exam (OAT). During that Summer 2019 of pure studying I also worked with Dr. Polidoro in her environmental/ Toxicology ...
