Накратко на български

Сребърните наночастици и техните производни се проучват при попадането им в почвата чрез земеделско използване на улукови утайки. Това помага за оценка на екологичните рискове и опасността за общественото здраве преди да възникне сериозна заплаха.

Fate and Toxic Effects of Silver Nanoparticles and Its Transformation Products in Soil Applied with Biosolids

Public health concerns have an impact for agri-food industry and so, Sewage Sludge Directive, SSD, includes standard values for pollutants to prevent the contamination of soil and not to lead to adverse effects on ecosystem and public. Recent studies showed that there is no need to revise the directive to include organic contaminants such as diclofenac, since they do not pose any considerable risk. However, risk assessment for nanomaterials is lacking. Silver nanoparticles (AgNPs) are among the most crucial nanomaterials with the production amount of 452 tons/year and 200 tons/year end up in wastewater treatment plants (WWTPs) , almost (>90%), in biosolids. Land spread of biosolids lead to the transfer of AgNPs and its transformation products to the soil environment. Therefore, addressing the fate and toxicity of AgNPs and its transformation products in the soil is essential for Environmental risk assessment (ERA). It is important to know the possible risks before a serious danger occurs for society when AgNPs are being widely used. The objectives of TESNinSAB project were including to understand the fate and effect of AgNPs and their transformation product Ag2SNP by considering the biosolid application in agricultural lands, the transformation ratio of AgNP, the organic matter content of soil and the aging of AgNPs in the environment.

Цел на проекта

Sewage sludge management is one of the most challenging waste issues in Environmental Engineering field due to their highly polluted nature and high volume. On the other hand, sewage sludge, which is also called as biosolids, can be a nutrient resource for the agri-foods which leads to their usage in agriculture as fertilizers. Usage of biosolids as fertilizer is the most desirable management strategy since it provides resource recovery and prevents the usage of synthetic chemicals which can be harmful for human and environment health. Therefore, after the treatment of biosolids to meet the required quality criteria, their ultimate disposal as fertilizer has to be sustained. Up to date, organic, metallic or hazardous pollutants were addressed to be removed from biosolids before land spreading and standards were defined in regulations. However, there are new concerning pollutants for biosolids application to agricultural lands. One of the most recent and biggest concerns is the presence of silver nanoparticles (AgNPs), which are widely used as biocides in the consumer products and are shown to occur in wastewater treatment plants, mostly, in biosolids. They are, as a source of ionic and nano Ag, among the emerging pollutants which are known to have potential to pose threat to human and environment health and have not been included in monitoring lists, yet. Therefore, the aim of this research is to advance the state of the art in land spread of biosolids through the investigation of the toxic effects and bioacculumation of AgNPs and its transformation products in soil organisms. For excellence in research, the knowledge about the toxic effects is integrated with environmental risk assessment which will enable necessary actions such as proposing guidelines for biosolids applications.
