Combined proteomic and gene expression analysis to investigate reduced performance in rainbow trout (Oncorhynchus mykiss) caused by environmentally relevant microplastic exposure

Microplastics and Nanoplastics

Table 1 Mean microplastic concentration in the experimental fish for each treatment. n = number of examined fish. SD = Standard deviation

Food pellet size	Treatment	n	Mean particle concentration ± SD [number per fish]

	Low exposure	15	15 ± 16
	High exposure	15	61 ± 47
4 mm	Control	15	0
	Low exposure	15	12 ± 16
	High exposure	15	86 ± 47
