Influence of watershed lithology on heavy metal levels in estuarine sediments and organisms in Galicia (North-West Spain)
Abstract The possible influence of watershed lithology on metal levels in estuarine sediments and organisms (macroalgae, phanerogams, molluscs and polychaetes) in Galicia (north-west Spain) wasExpand

Regional-scale monitoring of coastal contamination. Nutrients and heavy metals in estuarine sediments and organisms on the coast of Galicia (northwest Spain)
We determined background levels of heavy metals in sediments and biota of estuarine environments and nutrient reference levels in sediments of the Galician coast. This region is characterised byExpand

Uptake Kinetics of As, Hg, Sb, and Se in the Aquatic Moss Fontinalis antipyretica Hedw
Laboratory experiments were carried out to study the uptake kinetics of selected metals and metalloids in the aquatic moss Fontinalis antipyretica. For this purpose, moss specimens from a clean siteExpand

Analysis of temporal variability in the concentrations of some elements in the terrestrial moss Pseudoscleropodium purum
The uptake of contaminants by moss is a complex process that depends on the nature and characteristics of the contaminants and on the physicochemical and biological processes that affect the moss.Expand

Effect of growth on active biomonitoring with terrestrial mosses
The effects of growth of autoirrigated, shaded transplants of Pseudoscleropodium purum on the quantification of tissue concentrations of Cd, Cu, Hg, V and Zn, were investigated in 4 exposure periods,Expand

Seasonal variation in the concentrations of nutrients in two green macroalgae and nutrient levels in sediments in the Rias Baixas (NW Spain)
Seasonal monitoring of the levels of carbon, nitrogen and phosphorus in two green macroalgae (Ulva and Enteromorpha) was carried out at 22 sampling sites in four embayments (rias) on the northwestExpand

Nutrient Limitation in Macroalgae (Ulva and Enteromorpha) from the Rías Baixas (NW Spain)
.  Photosynthesis and growth rates in samples of two green seaweeds (Ulva and Enteromorpha) were monitored in the laboratory. The macroalgae were collected every 15 days from four coastal embaymentsExpand

Nitrogen and phosphorus in Ulva sp. in the Galician Rias Bajas (northwest Spain): Seasonal fluctuations and influence on growth
Coastal eutrophication has given cause for increasing concern. The Galician rias are ecosystems very sensitive to this phenomenon. In the present paper, we evaluate the possible nutrient limitationExpand
