Extended Data Fig. 4: Hg concentrations in wild and farmed fish across China.
From: Human activities shape important geographic differences in fish mercury concentration levels
a, THg (µg kg-1 ww), b, MeHg (µg kg-1 ww), c, MeHg%. Data are the comprehensive presentation of Fig. 2. FW and FF are short for freshwater wild and farmed fish, and MW and MF are short for marine wild and farmed fish, respectively. The detailed sample sizes are provided in the Source Data, and “n” represents the number of data points per graph. A Mann-Whitney U test was performed to compared fish Hg levels between groups. Based on Monte Carlo analysis (two-sided), a p-value less than 0.05 indicates statistically significance.
