| Abstract | The aim of the study was to characterize chemical and microbiological properties of soil substrates and fly ash contaminated with arsenic below the active impoundment on six different sites in Zemianske Kostoľany area. The substrate of the impoundment and soils around this site are seriously contaminated with arsenic (93–634 µg/g soil) and mercury (0.29–1.67 µg/g soil) exceeding the indication limits for sanitation. Most of the samples give alkaline pH values and low carbon content, which was increased with increasing humidity. This is closely related with the abundance of microorganisms—non-sporulating anaerobic bacteria dominated in the samples. The growth of r-strategists (80–90%) was recorded especially in the ash samples and in the samples with impurities of ash with elevated contents of arsenic and mercury. Among microscopic fungi dominated Ascomycota (75.8%) with Aspergillus niger and Penicillium chrysogenum var. chrysogenum which belong to the most tolerant species in this environment. The values of metabolic quotient for CO2 (qCO2) indicate that microorganisms are capable to utilize low sources of organic carbon in such damaged soils. However, low values of the substrate availability index indicate reduced potential of microbiota to degrade organic compounds. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
