CHANGING WEATHER PATTERN IMPACT ON SOIL MICROBIAL EFFICIENCY IN COMMON USED PHARMACEUTICAL CONTAMINANTS BREAKDOWN FROM SOIL ENVIRONMENT

Abstract

Soil that is a vital life supporting system is degraded mainly due to the pollution with several contaminants resulted usually from anthropogenic activities. At this moment, the pollution due to new emerging pollutants such as pharmaceutical products pose an additional threat to the soil system. Although use of manure as organic amendment has been proved to possess benefit effects, now it could be considered as a source in addition for soil pollution with pharmaceuticals. Soil microbial communities and soil physicochemical parameters are known that influence in most part pollutants behaviour and degradation in soil. Climate change could impact soil in terms of these parameters as well in terms of microbial content, thus pollutants degradation pattern could suffer changes. At this moment there are minor information on how changing climate will affect pharmaceuticals behaviour in the soil system. Therefore, the present work is aimed to assess pharmaceuticals pattern in soil under normal conditions and stress conditions associated with climate change drivers as anomalies of temperature, and wet, as well sudden temperature and wet changes. Soil enzymes catalyse consecutive stages of biodegradation of different contaminant substrates, leading to their decomposition. Climatic and habitat condition are very important determinants of the intensity of these processes. The activity of soil enzymes, which are catalysts of organic matter decomposition are correlated with soil biogeochemical and physical properties, microbial content, vegetation and with occurrence of various anthropogenic factors. Factors that influence soil biology and functioning is complex therefore assessment of soil enzymatic activity constitutes a necessary step towards understanding of pharmaceuticals dynamics and degradation patters in soil, especially under challenge of climate change.
