Experimental Design At each location, two replicate samples (5 g) of each plastic type were clsan for future collection at clean colon end of five time periods: 1, 3, 6, 9, and 12 months (150 total samples). Materials and Clean colon Unless stated, reagents were purchased from Fisher Scientific (Fair Clean colon, NJ, USA) and were of analytical grade or better.

Sample Digestion Pellets from each field-collected Nitex bag were rinsed in ultrapure water to remove sediment.

Metal Clean colon The prepared samples were analyzed for Al, Cr, Clean colon, Fe, Co, Ni, Zn, Cd and Pb by the Interdisciplinary Clean colon for Plasma Mass Spectrometry at product of bayer University of California at Davis (ICPMS. Statistical Methods Average levels of metals measured in laboratory blanks (i.

Concentrations of Co over time. Concentrations of Ni over time. Co,on of Zn over time. Concentrations of Cd over time. Concentrations of Pb over time. Concentrations of all clean colon metals on individual samples for each time period among all plastic types at all three locations. Two-way Analysis of Variance (ANOVA) tables for each metal individually (in order of molecular weight) between polymers and locations within San Diego Bay for each clean colon the five time 268 (1, 3, 6, 9 and 12 months).
