Residential publicity overview: A resource publication is the results of a multiyear attempt often called the Residential publicity overview venture (REAP) which used to be initiated by way of the Society for probability research and the foreign Society of publicity research. This textbook is the first made of the achieve and it comprises contributions from over 30 execs from numerous disciplines resembling chemistry, biology, physics, engi neering, business hygiene, toxicology, pharmacology, and environmental legislations, reflecting the various wisdom and assets essential to verify and deal with strength exposures taking place in and round the domestic.

When moderate concentrations were applied, some died after a while without apparent avoidance behavior, and some were able to avoid injurious concentrations 31 Behavior of Fish Exposed to Toxic Substances 0 20 40 60 80 100 120 140 160 180 200 220 240 260 MIN. FIG. 8. Reactions of minnow, Zacco platypus observed in gradients of toxic concentrations resulted from adding CuClo sol. to the tank. The reaction curves are common to three kinds of gradients of total Cu (upper), pH (middle) and total acidity (lower).
Since it makes the representation too complicated to accommodate all the data in this one figure, the average values in test of each toxicant are sum marized in every line. These linear relations, however, prove that the behavior of fish exposed to toxic substances have universally the conformity to Weber-Fechner's law. With such data, we can give equation (5) for general expression of avoidance behavior of fish exposed to toxic substances: dF/dC = k/C ( 5) where dC is the unit change oi^ toxic concentrations and C is the average concentra tion of toxicant in environment, and k is a constant.
As shown in FIG. 2, the organisms of subgroup 1 grew in the peptone water containing 7 per cent NaCl, but failed to grow in that containing 10 per cent of the salt. Cultures of subgroup 2 grew in both peptone waters. The organisms of subgroup 3 did not grow in peptone water containing 7 per cent NaCl nor in that containing 10 per cent salt. As seen from TABLE 1, all members of subgroups 1 and 3 gave negative Voges-Proskauer test, while those of subgroup 2 produced acetyl carbinol. Sucrose was fermented by subgroup 2, but not by subgroup 1.
