PRELIMINARY VEGETATION-BASED EVALUATION OF SEMI-VOLATILE ORGANIC COMPOUNDS (SVOCs) USING PINE SPECIES: TOWARDS POLLUTION DATA COMPARABILITY.

Pine needles are suitable biomonitors of airborne semi-volatile organic compounds (SVOCs). However, the various pine species, each with unique distribution and ecological traits, may differ in their ability to retain pollutants. The SVOC uptake capacities between different vegetation species remain largely unknown, and this study seeks to address this gap.

Empirical analysis and modeling of Argos Doppler location errors in Romania.

Background: Advances in wildlife tracking technology have allowed researchers to understand the spatial ecology of many terrestrial and aquatic animal species. Argos Doppler is a technology that is widely used for wildlife tracking owing to the small size and low weight of the Argos transmitters. This allows them to be fitted to small-bodied species.

Plants accumulating heavy metals in the Danube River wetlands.

Background: We present herein our results regarding the accumulation of four heavy metals (copper, cadmium, lead, and zinc) in four aquatic species plants (Ceratophyllum demersum, Potamogeton pectinatus, Potamogeton lucens, Potamogeton perfoliatus) collected from the Danube River, South-Western part of Romania and their possible use as indicators of aquatic ecosystems pollution with heavy metals.

Methods: Elements concentration from the vegetal material was determined through Inductively Coupled Plasma - Mass Spectrometry.

Results: The species were chosen based on their previous use as bioindicators in aquatic ecosystems and due to the fact they are one of the most frequent aquatic plant species of the Danube River ecosystems within the Iron Gates Natural Park.

Seasonal variation in trace metals concentrations in the Ialomita River, Romania.

Sampling streams for metals is an important aspect of water-quality monitoring. Using ICP-AES the concentration of some microelements in the Ialomiţa River (Romania) were determined. In order to grasp the different phases of the river regime, samples were collected from its water-sediment interface at seven locations along the river, during three campaigns: during snow melting periods in the mountain zones (April), the period of reduced flow and high water temperature (August) and the period of high precipitations (November).
