Metallothionein Induction in the Coelomic Fluid of the Earthworm Lumbricus terrestris following Heavy Metal Exposure: A Short Report

Table 1

Percentage variation of metallothionein concentration in L. terrestris coelomic fluid or whole organism following 72 h exposure to CdCl₂, CuSO₄ or a mixture of the two metals in OECD soil (for the concentration used see Section 2). The percentage variation was calculated according to the formula: (treated − control/control) × 100.

	Coelomic fluid	Whole organism
CuSO4	99.0±6.5	106.4±9.4
CdCl2	80.4±9.4	93.8±11.5
CdCl2 + CuSO4	149.0±6.5	130.5±7.0

Data are reported as mean ± S.E.M.
