The assessment for realistic CO2-adsorption capacities of different rocks is important for understanding the processes associated with CO2 storage. This paper investigates the adsorption characteristics of rocks for CO2 (limestone, sandstone, marl, claystone, clay, siltstone and metamorphic rock) by using a gravimetric method. The measurements were performed at 21°C with pressures from 1 up to 4MPa. Sandstone (and clay with sand/sandstone) showed the largest adsorption capacity at 21°C. The highest amount of in situ CO2 contents in measured samples was 21.4kg/t. The CO2-adsorption capacities were lower than past results in different coal samples. The results indicate that adsorption of CO2 into rocks may play an important role in storing CO2 in subsurface rock. © 2012 John Wiley & Sons, Ltd.

To evaluate the response and the accumulation capacity concerning tneir possible use for biomonitoring of metal pollution, five species of the Brassicaceae family were chosen as characteristic representatives of common vegetation types: Alliaria petiolata - typical for forest edge vegetation; Capsella bursa-pastoris - typical for the arable land; Diplotaxis tenuifolia - typical for road margins; Biscutella laevigata typical for closed, permanent grasslands, and Cardamine enneaphyllos - typical for the forest ground layer vegetation. Plants were collected at the beginning of flowering at three different locations in Slovenia: 1.) Vremščica Mountain (SW part of Slovenia, presumably unpolluted site); 2.) Celje (town in the middle of Slovenia, high contamination with metals due to the zinc industry), and 3.) Žerjav (Karavanke region of northern Slovenia with a century-old tradition of lead and zinc mining and smelting activity). Additionally two hybrids of oil seed rape (Brassica napus L. var. napus) were analyzed, crop plants, sown at differently polluted locations in Celje. Metal pollution of the soil correlated with the concentration of metals in aboveground plant parts, offering to use these species as biomonitors of metal pollution in different types of natural and semi-natural vegetation. They can be used for monitoring short-term changes in heavy metal polluted arable land and urban areas as well as for monitoring long term heavy metal pollution of forests. None of the plant species of our investigation proved to be a feasible candidate for use in phytoremediation.

The study was conducted at three locations in the Savinjska region of Slovenia, where soil is contaminated with heavy metals due to the zinc industry (Cinkarna Celje). In Ponikva the soil to a depth of 30 cm contains 0.8 mg kg(-1) Cd, 32.2 mg kg(-1) Pb, and 86 mg Zn kg(-1), in Medlog 1.4 mg kg(-1) Cd, 37.4 mg kg(-1) Pb, and 115 mg kg(-1) Zn and in Skofja vas 10.9 mg kg(-1) Cd, 239.7 mg kg(-1) Pb, and 1356 mg kg(-1) Zn. The pH at the selected sites was between 7.3 and 7.6. In the beginning of September 2006 two hybrids of Brassica napus L. var. napus, PR45 D01 and PR46 W31 suitable for production of biodiesel obtained from Pioneer Seeds Holding GmbH, were sown. After 96 days juvenile and after 277 days mature plants were collected. Parts of plants (root, shoot and seed) were separated and Cd, Pb, Zn, Mo, and S determined by ultra-trace ICP-MS. We compared the uptake of Cd, Pb, Zn, Mo and S in different parts of juvenile and mature plants of the two different hybrids, TF (translocation factor), BAF (bioaccumulation factor), and PP (phytoextraction potential) were calculated. The mature hybrid PR46 W31 had higher shoot/root ratio and higher PP for metals (Cd, Pb, and Zn) and lower PP for the micronutrient (Mo) and macronutrient (S) on the polluted site. The study demonstrated the potential use of oilseed rape on multiply polluted soils for production of 1st and 2nd generation biofuels. The potential restoration of degraded land could also disburden the use of agricultural land.
