摘要
Barite crystals were formed on the inner shell surface in 1 week by specimens of Corbicula fluminea exposed to dissolved Ba concentrations of 140-559-mu-g liter-1. Prevalences of barite crystals increased directly with initial Ba concentrations over the course of a 28-d experiment. Barite crystals were not observed on the shell exteriors of any clams analyzed. Results suggest that Ba was concentrated by C. fluminea and periodically purged from the soft tissues into the extrapallial fluids, where it heterogeneously coprecipitated with aragonite on the inner shell surface.
