From: Plastic leachates impair picophytoplankton and dramatically reshape the marine microbiome
Impact of plastic leachate and zinc on phytoplankton and bacteria over the 6-day experiment. Cell counts of a Synechococcus and photosynthetic picoeukaryote (PEUK) populations and b high-DNA bacteria (HDNAb) and low-DNA bacteria (LDNAb) populations throughout the 6-day experiment. Data points represent flow cytometric cell counts derived from the mean values of the quadruplicate biologically independent samples (except for high zinc (ZnH), for which just 2 replicates are available). The lowercase letters identify which treatments were found to be statistically significantly different (p < 0.01) at the final time point (6 days of exposure). Impact of PVC plastic leachate and zinc treatments on c photosynthetic quantum yield (Fv/Fm) during the 6-day experiment and d final chlorophyll a concentration (after 6 days of exposure). Data points are the average for quadruplicate independent biological samples (except for ZnH, where n = 2). For 10% PVC samples, there was no detectable photosynthetic capacity after day 2. Error bars on each point represent the standard deviation. PVC1, 1% PVC leachate; PVC10, 10% PVC leachate; ZnL, low zinc; ZnH, high zinc
