This week I am excited that I have collected over 50 sand samples from all over the United States with help of friends and colleagues! I have also been able to borrow some historical samples from different places in the world! I will be testing all of the samples for the presence of microplastics as well as collecting what I find in each sample to run some new testing procedures to determine what they are and hopefully give us an idea what the main pollution source is in each area .
