Fig. 6From: How much do the conventional parameters contribute to the biological toxicity of surface water in different types of villages?Bar graph of correlations between acute toxicity and conventional parameters in A agricultural village surface water, B breeding village surface water, C industrial surface water, D tourism village surface water and E agriculture and breeding mixed village surface water. *p < 0.05; **p < 0.01. The gray dashed lines were set at correlation coefficient values of 1 and − 1, which means maximum positive and negative correlations, respectivelyBack to article page
