Environmental protection has a key role in the context of crisis management. It is not just about development of the industry of environmental protection and implementation of new ways of management in innovative solutions in solving problems. Important area of improvement is also revision of environmental legislation aiming at simplification and reduction of costs of procedures for the busines...

Estimating standard-exceeding probabilities of toxic metals in soil is crucial for environmental evaluation. Because soil pH and land use types have strong effects on the bioavailability of trace metals in soil, they were taken into account by some environmental protection agencies in making composite soil environmental quality standards (SEQSs) that contain multiple metal thresholds under diff...

Urban planning is the space expression of urban resource configuration. Its central goal is using the effective resource with the lowest ecological cost in exchange for the greatest economic benefits. The current city’s expansion which is dominated by the development, is too fast, which has overlooked the balance between planning and environmental protection. The contradiction between urban dev...

The research objective of the project and article “European Ecological Network Natura 2000 – opportunities and threats” Natura 2000 sites constitute a form of environmental protection, several legal problems are likely to result. Most controversially, certain sites will be subject to two regimes of protection: as national parks and as Natura 2000 sites. This dualism of the legal regulation make...

Growing interest worldwide to boost innovation in business sector activities, especially the technology, is intended to maintain or increase national economic competitiveness, inclusively as an effect of awareness concerning the effects resulting from economic activity on consumption of resources and environment, which requires design of new patterns of production and consumption. In this paper...

In this study, we introduce the prospect of using prognostic model-generated meteorological output as input to steady-state dispersion models by identifying possible advantages and disadvantages and by presenting a comparative analysis. Because output from prognostic meteorological models is now routinely available and is used for Eulerian and Lagrangian air quality modeling applications, we ex...

BACKGROUND Liao River basin in Jilin Province is the place of origin of the Dongliao River. This study gives a comprehensive analysis of the vegetation coverage in the region and provides a potential theoretical basis for ecological restoration. METHODS The seasonal variation of vegetation greenness and dynamics based on the Normalized Difference Vegetation Index (NDVI) in major land cover ty...
