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 .

Coregonus Lavaretus

The study reveals the results of the analysis of fatty acid composition of muscle, liver and gonad tissues of the whitefish Coregonus lavaretus L. of different ages from lakes Lovozero and Umbozero of the Kola Peninsula. The analysis of fatty acid composition in organs and tissues allows to evaluate the physiological characteristics of the organism. It was found that the content of monoenoic fatty acids in the muscles of the whitefish from lake Lovozero is higher than that of the whitefish from Umbozero. It is probably due to the features of the food base of the objects studied. In the muscles of immature whitefish of lake Umbozero the content of polyenic fatty acids is higher compared to the fish from Lovozero. The content of PUFA significantly increases in the mature whitefish from Umbozero lake perhaps due to the temperature regime in water bodies and different rates of motor activity of fish. Lower levels of PUFA in the liver of the whitefish from Lovozero lake may indicate reduced metabolism in hepatocytes. In the gonads of female whitefish from the studied water bodies, the content of saturated fatty acids is low compared to the polyene fatty acids which is characteristic for the viscosity reduction in the membranes of oocytes.
