Background: Since the outbreak of COVID-19 pandemic, psychological distress is increased. Transdiagnostic mechanisms, including trauma, personality functioning, mentalizing and emotion regulation are considered relevant to the development and maintenance of mental health problems and therefore may play a role in individuals’ reactions to the pandemic.Aim: To identify moderating and mediating factors associated with pandemic-related distress and mental health problems in adults and families, we aim to investigate the interactions of interpersonal trauma (childhood trauma and domestic violence), psychological capacities (personality functioning, mentalizing and emotion regulation) and pandemic-related adversity on psychological distress during the COVID-19 pandemic. Furthermore, we aim to investigate behavioral and cognitive consequences of the pandemic (e.g., media consumption, vaccination status, conspiracy beliefs).Methods: Using an online-based cross-sectional and longitudinal design, we will investigate a sample of adult participants recruited via online platforms in German-speaking countries over the course of 1 year with four measurements points via self-report instruments (personality functioning: PID5BF +; mentalizing: MentS, PRFQ; emotion regulation: DERS-SF; mental health problems: PHQ-9, GAD-7; a composite pandemic-related stress score). Structural equation and multi-level modeling will be performed for data analyses.Implications: This study will provide data on the moderating and mediating effects of trauma, personality functioning and mentalizing during the pandemic in a large community sample, particularly on vulnerable groups like families. Identifying transdiagnostic mechanisms of psychopathology in the course of a pandemic crisis may provide valuable insight for the development of pre- and intervention measures for potential psychological distress during and post the pandemic.

Petroleum hydrocarbons (PHCs) react with oxygen by low temperature oxidation (LTO) to produce a coke-like solid residue, carbon oxide gases, and vaporized hydrocarbons. The feasibility of using LTO to remediate sandy soil contaminated with motor oil has been investigated in a plug flow reactor operated at temperatures between 150 and 221 °C and with air injection fluxes ranging from 0.40 to 2.28 m3(ST)·m–2·h–1. Low temperature oxidation occurred in three successive periods: the induction period during which the oxygen depletion in the reactor exit stream remained small, the middle period characterized by peaks in oxygen depletion and carbon oxide concentrations, and the tailing period corresponding to very gradual decreases in oxygen depletion and carbon oxide concentrations. The extents of oxidation measured in our tests ranged from 29 to 37 moles O2/kg oil. Soil samples treated at temperatures between 167 and 176 °C met all the Tier 1 levels of the Canada Wide Standard for PHCs in coarse-grained surface soils, except those for soil contact and protection of ground water. Concentrations of individual polycyclic aromatic hydrocarbons (PAHs) in the soil samples treated at 167 and 176 °C complied with the Canadian Environmental Quality Guidelines for all soil types. Key words: low temperature oxidation, petroleum hydrocarbons, remediation, soil, motor oil.
