During the course of study on vertical migration and mortality of benthos in simulated dredged material, changes in pore water chemistry and sediment geochemistry were also examined. Dissolved oxygen, ammonia, and sulfide showed significant changes between overlying water and pore water over the two week experimental period. Chemical effects in dredging operations can be important on infaunal organisms.
