(A) Absorption per cross section (ABS/CS), (B) trapped energy per cross section (TR/CS), (C) electron transport per cross section (ET/CS), (D) dissipation per cross section (DI/CS) of L. minor espoused to various concentration of mercury. Values presented are the average of three replicates, and standard errors are represented by error bars. Different characters indicate significant differences among the results (p ≤ 0.05).
