Spartina alterniflora decomposition was monitored in the high and low salt marsh in litter bags (2-mm mesh). The detritus formed in this process was analyzed at various times for ash-free dry weight (AFDW) (combustion at 550 °C), total carbon (wet combustion to CO2), and total nitrogen (Kjeldahl digestion). A mathematical component model predicting...

A prototype electrical cross-flow filtration system (ECFF) was designed and used to improve the separation of nano-sized particles from water. Model colloids, e.g., γ-Al2O3 and SiO2, and naturally occurring colloidal particles collected from well waters in the state of New Jersey were used to evaluate the performance of the ECFF module. Results ind...

This study examines the effects of sequential filtration on the particle abundance and lead concentrations in ground water from four monitoring wells in New Jersey with a history of high turbidity, elevated metal concentrations, or where differences in metal concentrations exist between filtered and unfiltered samples. In these monitoring wells, bo...

We investigated the source and composition of free and protein-bound amino acids during the decomposition ofSpartina alterniflora Loisel in laboratory percolators and in a field experiment in the Great Sippewissett Marsh (Falmouth, Massachusetts). In the percolator experiment, 50% of the nitrogen (N) could be extracted fromS. alterniflora litter in...

The effect on decomposition of 4 different levels of nitrogen in aerial tissue ofSpartina alterniflora, collected at the end of its growing season litter, was studied in laboratory percolators for 56 days at 20‡C. The CO2 evolution and the release of organic nitrogen and organic carbon were monitored. From these data, the ash-free dry weight (AFDW)...

Detritus of .S.part!na alterniflora is the base of many estuarine food chains (MARINUCCI 1982). During the formation of detritus from Spartina litter, polychlorinated biphenyls (PCBs) are accumulated by this detritus from surrounding contaminated water (MARINUCCI and BARTHA 1982). This PCB accumulation is amplified by the litter microbiota, which a...

The accumulation of a polychlorinated biphenyl (PCB) mixture (Aroclor 1242) in the process of detritus formation by a shredded marshgrass (Spartina alterniflora) under aerobic conditions was monitored in percolators for 4 months at 20 degrees C. Dissolved PCB in the influent solution was 14 to 16 mug/liter. Parameters monitored in addition to PCB a...

The carbon and nitrogen in Spartina alterniflora litter were monitored for 4 months during decomposition at 20°C in a flow-through percolator that simulates an aerobic, moist marsh. Both the evolution of CO2 and The loss of carbon from the litter followed exponential decay kinetics (0.5% day-1 and 1.0% day-1). At first both total organic carbon and...

A re-evaluation of current data on production and decomposition of Spartina alterniflora in North American salt marshes, with regard to the role of these processes in the estuary, has resulted in the following generalisations. Aerial production of S. alterniflora over its geographical range lies between 550 and 2000 gm −2 year −1 by dry weight, wit...

The biodegradation of radiochemically pure (99%) 1,2,3- and 1,2,4-trichlorobenzene (TCB) in soil was investigated. Experimental difficulties posed by the high volatility and slow biodegradation rate of the TCBs were partially overcome by using a specially designed incubation and trapping apparatus. Evolution of (14)CO(2) from active versus poisoned...

Quantitative mineralization studies on radiolabeled compounds having high vapor pressures need to cope with several technical difficulties. An incubation and trapping system is described that was successfully used in mineralization studies on highly volatile trichlorobenzenes and other xenobiotic pollutants.
