Abstract |
A programmable control system for salinity has been developed and coupled with a flow-through toxicant exposure system. The resulting apparatus allows study of influences of constant and fluctuating salinity regimes on responses of estuarine organisms exposed to selected pollutants. Constant and fluctuating salinity profiles available through use of the system (a) may be selected to range from fresh water to full-strength ambient seawater values; (b) are automatically repeatable, allowing long-term study; (c) are reproducible, thus permitting replication of treatment combinations over time and sequential testing of several species at a common salinity regime; and (d) can be quickly and easily modified or substituted for by another profile. |
