Factors influencing the rate of polychlorinated biphenyl dechlorination in Hudson River sediments
Article Abstract:
A study of Hudson River sediments gives important information on factors which have an impact on the rate of polychlorinated biphenyl (PCB) dechlorination, comparing results from laboratory experiments with environmental changes known to take place. PCB concentration seems to have an impact on dechlorination rates under laboratory conditions which is in line with dechlorination rates taking place naturally in anaerobic sediments, and anaerobic dechlorination can be shown to take place in many different environments under widely differing conditions. This indicates that dechlorination is probably a common feature of many anaerobic organisms.

Partitioning of polychlorinated congeners in the seawater of New Bedford Harbor, Massachusetts
Article Abstract:
The division of polychlorinated biphenyl congeners between particulate and dissolved phases of seawater along New Bedford Harbor, MA, was investigated using regression analysis. The results showed that the partitioning process was subject to seasonal trends. Around 70% of the variability in the log of the partition coefficients along the polychlorinated biphenyl gradient was due to temperature.
