QUALITY OF RAINWATERS OUTFLOWING FROM ROOFS OF GARAGE BUILDINGS OF PARK AUTHORITY OF ROZTOCZE NATIONAL PARK

Rational use of surface and underground waters leads to a reduction in their consumption, which is currently one of the fundamental tasks in the field of the conservation of waters, in its broad sense. This includes also the utilisation of water from additional sources, such as e.g. precipitation water. The paper presents an analysis of the quality of rainwater outflowing from the roofs of garage buildings of the Park Authority of the Roztocze National Park. The results of analyses presented in the paper indicate a favourable composition of rainwater that meets the norms defined for water for human consumption. In the waters under analysis, exceeded levels were noted for ammonia, manganese and biological factors, but these do not preclude the use of the waters for household purposes. Rainwaters at the Roztocze National Park can be used for car washing, for the irrigation of green areas, or for toilet flushing. Such utilisation of rainwaters can largely contribute to a reduction of the use of high-quality underground waters

Novel Ecosystems in the Urban-Industrial Landscape–Interesting Aspects of Environmental Knowledge Requiring Broadening: A Review

Human activity is affecting and transforming the natural environment, changing the ecosystem mosaic and natural biogeochemical processes in urban-industrial landscapes. Among the anthropogenic ecosystems, there are many present features of Novel Ecosystems (NE), e.g., the de novo created habitats on post-mineral excavation sites. The biological nature of the functional mechanisms of Novel Ecosystems is mostly unknown. In natural and semi-natural ecosystems, biodiversity is considered as the primary element influencing ecosystem processes and functioning. The preliminary studies conducted on post-mineral excavation sites have shown that, in poor oligotrophic habitats, the species composition of the assembled vascular plants is non-analogous, distinctive, and not found in natural and semi-natural habitats. This paper aims to present the gaps between scientific identification of the biological mechanisms driving ecosystem processes and functioning (including the expanding areas of Novel Ecosystems created de novo). Among the identified gaps, the following issues should be listed. The detailed identification and understanding of the processes and biodiversity-dependent functioning of Novel Ecosystems is crucial for proper environmental management, particularly when facing the challenges of ecological constraints and of global change. The ecology of Novel Ecosystems is a social and economic issue because of the relationships with densely populated urban-industrial areas
