It was found that the cercariae in the two studies showed different susceptibility to zinc.
A bill based on the weight of the copper (and later zinc), and hence the amount of electricity used, was sent to the household.
The other subunit combinations would also be sensitive to zinc, but to a lesser extent.
Diluted solutions of zinc and copper chloride and sodium hydroxide were used.
In the present study, the metals chosen (copper, zinc, manganese and iron) are all essential for normal molluscan metabolism but are toxic at high concentrations.
Transfusions of albumin and immunoglobulins were needed every 2 weeks, as well as substitution with calcium, magnesium and, later on, zinc.
