Fatal Fulminant Hepatic Failure in a Case of Zinc Phosphide Poisoning: A Case Report

Rodenticide is the term given for the compounds that are used in the killing of rats. The commonest compounds that are available as rodenticides are Aluminum phosphide, Zinc Phosphide, Yellow Phosphorus and Coumarins. Due to their easy availability in the general stores, these also have been used as a source of inflicting self-harm by the patients in order to commit suicide. Most of the patients escape the poisonous side effects with a mild course, but some cases progress to a state of Acute liver failure or fulminant liver failure. Due to the broad range of symptoms that can occur with the compounds, it is important to discuss the course of progression of symptoms from mild to severe in order to understand the treatment protocols to treat the patient appropriately. Some patients progress to such a severe form of symptoms that there is an urgent indication of liver transplantation. Here we report a case of rodenticide poisoning in a young female which started off with a mild course and ultimately progressed to fulminant liver failure leading to a fatal outcome.

Conditions for the Development of Phase Components K2CaP2O7 , KCaP3O9 in Toxic Dust

The present study analyses the composition and main components of toxic dust. To develop and understand the methods of controlling the dust generation process, it is necessary to study the data that provide detailed information about the reaction mechanism. The results of studies of the phase composition of dust conducted in the laboratory and their comparison with the data obtained earlier by other authors allowed establishing a fairly reliable diagnosis of the phase composition of dust. The analysis revealed that the dust of various phosphorus plants comprises the same basic components, yet the chemical bonds between them differ. The purpose of this study, conducted in the research laboratory of the Zhambyl Branch of LLP “Kazphosphate” (NDFZ) is to investigate the possibility of using new toxic dust, as well as the toxic dust from storage tanks to obtain NPK fertilisers. The study comprises three stages of investigating the oxidation of elementary phosphorus with nitric acid, since elementary yellow phosphorus is dangerous for the environment. As a result of the 1st stage of the study, it was found that toxic dust oxidised with nitric acid cannot be used as a fertiliser, since a non-technological mass is generated, such as acid resin, which is not suitable for drying and granulation. To neutralise the acid reaction mass, it was decided to use an aqueous solution of ammonia, thereby increasing the nutrient content and obtaining a complex NPK fertiliser. In the course of the study, the authors found in the 2nd and 3nd stages of the experiment that to obtain a productsuitable for fertilisation, it is necessary to strictly control the content of elemental phosphorus in the initial toxic dust and adjust the consumption of nitric acid based on its results
