Note: a = Total weight of oligochaete tissue in each test vessel.
b = Concentration of naphthalene in the oligochaete tissue determined using
the technique of HPLC.
c = Total amount of naphthalene in the oligochaete tissue calculated by
multiplying a total weight of oligochaete tissue (a) with a concentration of
naphthalene determined in each test vessel (b).
