where CI m stands for mean cardiac interval
which is related to HR as HR = 60/CI m , and SD
—standard deviation.
An alarm signal is produced only if not less
than four of the six crayfish and fish simultaneously show significant reactions.
Integral indicating qualitative measures of
water toxicity level are formed as a “traffic
lights” system. The suggested system for the
production of “traffic lights” is as follows:
