Will climate change increase irrigation requirements in agriculture of Central Europe? A simulation study for Northern Germany
By example of a region in Northern Germany (County of Uelzen), this study investigates whether climate change is likely to require adaption of agricultural practices such as irrigation in Central Europe. Due to sandy soils with low water retention capacity and occasional insufficient rainfall, irrigation is a basic condition for agricultural production in the county of Uelzen. Thus, in the fram...


Mechanisms and optimization of oil palm empty fruit bunch as a pre-grown source for white-rot fungus to degrade DDT
Utilization of an oil palm industry waste, oil palm empty fruit bunch (OPEFB) in the environmental technology field is still limited. OPEFB has the potential to be used as a pre-grown source for white-rot fungi (WRF) because it induces ligninolytic activity that can be used to degrade organopollutants. Therefore, the ability of OPEFB as a pre-grown source for white-rot fungus, Trametes versicol...
Phytoremediation of textile effluent pretreated with ultrasound and Bacteria
This study presents the phytoremediation of textile effluent pretreated with ultrasound irradiation and microbial treatment. The isolates such as Ochrobactrum sp., Pseudomonas aeruginosa and Providencia vermicola were used for the bacterial degradation and phytoremediation was done using Bouteloua dactyloides. The effect of sonication time on the performance of phytoremediation was evaluated. O...


Impact of compost process temperature on organic micro-pollutant degradation
Aerobic composting has gained considerable attention because of its ability to remove organic micro-pollutants. Compost process temperature is a key parameter controlling degradation rate. Impact of process temperature on removal of 15 key organic micro-pollutants often found in sewage sludge (including two metabolites) during sewage sludge composting was investigated at 18–70°C over 52days....
Latex paint as a delivery vehicle for diethylphthalate and di-n-butylphthalate: Predictable boundary layer concentrations and emission rates
The description of emission processes of volatile and semi-volatile organic compounds (VOCs and SVOCs) from building products requires a detailed understanding of the material and the air flow conditions at the surface boundary. The mass flux between the surface of the material and air depends on the mass transfer coefficient (hm) through the boundary layer, the gas phase concentration of the t...


Fish eyes and brain as primary targets for mercury accumulation — A new insight on environmental risk assessment
Fish eyes and brain are highly susceptible to environmental Hg exposure but this issue is still scarcely investigated, mainly regarding methylmercury (MeHg) accumulation. Yet, Hg levels in fish lens have not been previously examined under field conditions. Total Hg (tHg), MeHg and inorganic Hg (iHg) levels were assessed in the brain, eye wall and lens of the golden grey mullet (Liza aurata) fro...
Ecotoxicity effects triggered in aquatic organisms by invasive Acer negundo and native Alnus glutinosa leaf leachates obtained in the process of aerobic decomposition
The replacement of autochthonous tree species by invasive ones in coastal zones of freshwater bodies induces additional alteration of hydrochemical and microbiological characteristics due to decomposition of fallen leaves of non-indigenous species, which can lead to ecotoxic response of the littoral biota. Leaves of invasive to Lithuania boxelder maple (Acer negundo) and autochthonous black ald...

A protocol for machine-readable cache policies in OGC web services: Application to the EuroGeoSource information system
An efficient access to the contents provided through OGC web services, widely used in environmental information systems, is usually achieved by means of caching strategies. Service-owners may be interested in expressing the conditions required to allow for this. If these conditions are expressed in a machine-readable way, automatic harvesters can be programmed to follow them. This paper propose...
A decision support system for on-line leakage localization
This paper describes a model-driven decision-support system (software tool) implementing a model-based methodology for on-line leakage detection and localization which is useful for a large class of water distribution networks. Since these methods present a certain degree of complexity which limits their use to experts, the proposed software tool focuses on the integration of a method emphasizi...

Effects of Fertilization on Grasshopper Grazing of Northern Gulf of Mexico Salt Marshes
Grazing frequency, grazing intensity, plant health, and grazer abundances were examined under two different fertilization regimes and compared to unfertilized areas of Juncus roemerianus (black needlerush) marsh. These measurements were taken in three separate sites: two low elevation sites and one high elevation site. Fertilizer was added over one grazing season (April–August) with measureme...
Ecological and Social Outcomes of a New Protected Area in Tanzania
Balancing ecological and social outcomes of conservation actions is recognized in global conservation policy but is challenging in practice. Compensation to land owners or users for foregone assets has been proposed by economists as an efficient way to mitigate negative social impacts of human displacement from protected areas. Joint empirical assessments of the conservation and social impacts ...

Positive Feedback Loop between Introductions of Non-native Marine Species and Cultivation of Oysters in Europe
With globalization, agriculture and aquaculture activities are increasingly affected by diseases that are spread through movement of crops and stock. Such movements are also associated with the introduction of non-native species via hitchhiking individual organisms. The oyster industry, one of the most important forms of marine aquaculture, embodies these issues. In Europe disease outbreaks aff...
The Potential for Biodiversity Offsetting to Fund Effective Invasive Species Control
Compensating for biodiversity losses in 1 location by conserving or restoring biodiversity elsewhere (i.e., biodiversity offsetting) is being used increasingly to compensate for biodiversity losses resulting from development. We considered whether a form of biodiversity offsetting, enhancement offsetting (i.e., enhancing the quality of degraded natural habitats through intensive ecological mana...
An Experimental Investigation of Hard and Soft Price Ceilings in Emissions Permit Markets
Tradable emissions permits have been implemented to control pollution levels in various markets and represent a major component of legislative efforts to control greenhouse gas emissions. Because permits are supplied for a fixed level of pollution, allowing the market for permits to determine the price, price control mechanisms may be needed to protect firms from price spikes caused by fluctuat...
Enhanced bioremediation of soil from Tianjin, China, contaminated with polybrominated diethyl ethers
This work aimed to evaluate the effectiveness of nutrients, H2O2, and tourmaline on the bioremediation of fields where the soil was contaminated with polybrominated diethyl ethers (PBDEs). The results showed that 39.2, 38.3, and 48.1 % of total PBDE removal was observed in microcosms with the addition of nutrients, such as NaNO3, NH4Cl, and NH4NO3, respectively, compared to only 15.2 and 5.8 ...
