Table 3. Numbers and percentages of total numbers of T-RFs (in parentheses) in earthworms after 30 days which were significantly different (decreasing or increasing) between the soil treatments (−Hg, +inorganic-Hg; +methyl-Hg).

	Decreased	Increased
−Hg versus +inorganic-Hg	8 (11)	0 (0)
−Hg versus +methyl-Hg	11 (16)	2 (3)
+inorganic-Hg versus +methyl-Hg	0 (0)	2 (3)

Total number of T-RFs in earthworms: n = 71.
