Incident Analysis

A forensic engineering analyses of a chemical incident is presented that was classified as a self-sustaining decomposition (SSD) event, which occurred in a load of 10,000 tons of NK 21-00-21 fertilizer bulk stored inside a warehouse in the city of São Francisco do Sul in Brazil. The chemical reaction developed within the fertilizer mass and took several days to be controlled, resulting in the evacuation of thousands of residents. The water used to fight against the reaction, after having contact with the load of fertilizer material, promoted changes in adjacent water bodies, causing the death of animals (fish, crustaceans, and amphibians). The smoke from the chemical reaction products damaged the incident’s surrounding vegetation. Large SSD events are rare, with an average worldwide frequency of one every three years. Therefore, in addition to presenting a case study of this type of phenomenon, the main objective of this work is to discuss the causes that led to SSD reaction at this event, evaluate its consequences, and motivate future studies.

Wastewater Treatment Systems

Metagenome-assembled genome sequences (MAGs) were generated from two wastewater treatment systems in two German cities (Göttingen and Greifswald), based on metagenomes derived from hospital effluent, different wastewater treatment stages, and adjacent water bodies. The MAGs mainly originated from bacterial members of Proteobacteria , Bacteroidota , Firmicutes , “ Candidatus Patescibacteria,” Actinobacteriota , Chloroflexota , Desulfobacterota , and Verrucomicrobiota .

It has been shown that the status of some Karelian water bodies had changed as a result of human impact and atmospheric precipitation has a role in the surface waters’ chemical composition formation. Assessment of biogenic elements and organic matter input to the Lake Onego and the Lake Ladoga from various natural and anthropogenic sources has been done. Higher load from point sources in comparison with diffuse sources has been registered for the Lake Onego in comparison with the Lake Ladoga. Many-year change of the Vygozero reservoir water chemical composition has been presented. This reservoir receives the Segezh paper-pulp plant waste waters and the Kenti River system waters with technogenic waters from the Kostomuksha mining/concentrating plant. It has been stated that atmospheric precipitations serve the main source of the biogenic elements and heavy metals input, while input of mineral and organic substances with the precipitation is insignificant. For the first time assessment of the Karelian water bodies’ state caused by the natural, climatic, and anthropogenic factors’ impact has been done.
