Blog Post Week 12

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.

    Hey, Jasmine, the fact that the SPI6 plastic is dragging your data analysis because it took longer dry up must have been bad news. Last week you were ready for your data analysis, which would’ve been interesting. You shouldn’t be worried though; sometimes setbacks give the best lessons. Now we know SPI6 plastic types take longer to dry up.

    Hey Jas,

    Congrats on almost being done with your project! I'll definitely be interested in seeing your results, since I love looking at graphs and I know you have like a 1000 of them that you've made. :)

    Hi Jasmine, I am relatively new to everyone’s research projects, but from what I am reading in your blog post you are extracting different types of micro-plastics and weighing them. Correct me if I am wrong but you are you trying to determine which one degrades faster. From what I read from your older posts you have been working on this project for a year, so I am certain you have obtained very interesting information. I can’t wait until you present this, I would really love to know more.

This week in lab I finished all the NaCl samples that were run through the vacuum machine. I also ran them with hydrogen peroxide for at least 3 days so that it could get rid of all the nature particles that could be perhaps ruin the measuring at the end. Once all the samples were dried there were some that had sodium chloride attached to them, so because that could have been also a percent error when measuring the plastic I had to clean them and wash them off with DI water and run them through the vacuum machine again. In the process of doing that I ran out of the filters that are attached to the machine so I really only got done with half of the 30 samples. Matt will be ordering more filters the following week but mean while I will be getting the next samples ready that will be run with potassium carbonate. I will have to shred more plastic for all 30 samples again. I have finished collecting sediment and those will be distributed. Really wish we had one of these machines that could

Abstract: Arizona: Lakes, Ponds, and Canals potential impacts of chemical exposures on aquatic bird species   Surface water in metro-Phoenix is contaminated due to urban pollutants, impacts from water reuse, soils, and other human interactions. Harmful contaminant levels, in addition to Nitrate-N, Phosphate- P, temperature, and dissolved O2 may possibly have negative consequences on resident and visiting bird species’ populations. Therefore, we conducted a two-year study of bird use of urban aquatic resources across the metro-Phoenix area, which has raised concerns about the transfer of chemical contaminants from surface water to bird species. The pattern that we see in bird populations in urban aquatic resources appears to be seasonal, with some study sites showing a year-round pattern of use. For highly-used aquatic sites in particular, we report concentrations of water contaminants that may be impacting aquatic bird species. Given that Phoenix is part of the Urban Bird Treaty pro
