In the early 1970's, the utility of caged bivalves as an environmental monitoring tool
became apparent.
Over the past 30 years many conceptual breakthroughs have been
made by a variety of investigators
but the Salazars have been instrumental in
refining those methods beyond what many have even considered and
developing protocols for in-situ monitoring using bivalves to a level
comparable to laboratory bioassays. These improvements include the
use of a minimum size rangegenerally 10 mm or less, compartmentalized
cagesthat facilitate multiple measurements on the same
individual, digital
measurements that reduce processing time, and multiple
measurement endpoints to characterize chemical exposure and
biological effects for assessing ecological risk.
