Abstract
Background and Aim: In the occurrence of natural or man-made crises, the productivity of human forces in crisis management, especially nurses, have enormous importance because saving the lives of nurses is crucial for continued relief and rescue and the correct activities make operations of relief, rescue, and healing successfully. Keeping nurses calm in a crisis guarantees the health and productivity of human resources. The current study was done to determine the hindering factors of nurses' calm in a crisis.
Methods: This qualitative study was conducted from November 2019-February 2020 in Tehran, Iran. Interviews were recorded from 15 expert nurses in the trauma ward of Baqiyatallah hospital and 15 experienced nurses in the National Medical Emergency Organization. Using the three-pronged analysis model of organizational pathology (structural, contextual, content factors) and interviewing experts, the factors that inhibit nurses' calm in critical situations were identified. Finally, prioritization of the hindering factors of nurses' calm in crisis was performed by Friedman test and corrective measures related to these factors were examined.
Results: Three main themes were identified as the hindering factors of nurses' calm in a crisis. These three main themes include factors that lead to emotional turmoil, cognitive confusion, and behavioral perturbation. The sub-categories of each of the three themes include structural, contextual, and content factors. Infection of nurses with viral, chemical and microbial agents, inconsistencies between managers and agencies in charge of crisis management, unfamiliarity with crisis management, problems in the quantity and quality of equipment and medicine, and problems with hospital structures are identified as the most important factors hindering nurses' calm in a crisis.
Conclusion: Numerous structural, contextual, and content factors have caused nurses to be disrupted in crisis, which can be greatly reduced by the correct implementation of instructions related to crisis management and empowerment and development of nurses' competencies.

Abstract
Background and Aim: The presence of oil installations, wharves and refineries in the coastal strip of Bandar Abbas causes the release of a large amount of oil pollutants that eventually reach the sediments and cause bioaccumulation in the macrobenthic communities that live in the sediments. A ring in the sediments and their comparison in the tissue of four groups of macrobenthic communities, including gastropods, bivalves, crustaceans, and paraterans, were made in the waters around Bandar Abbas.
Methods: To measure the concentration of polycyclic aromatic Hydrocarbon in the sediments and macrobenthic communities present in it, sampling was done at 9 stations using a Grab Van Veen device along the coastline of Bandar Abbas in March 2018 and March 2019.
Results: The mean concentration of total PAHs by station showed that the refinery has the highest concentration of these compounds, followed by Posht-e-Shahr and Soro. The highest average concentration of polycyclic aromatic hydrocarbons in gastropods belonged to the 3-ring compound Acenaphthene with an average (ppb) of 1117 and the lowest value belonged to the 6-ring compound Benzopyrylene with an average (ppb) of 2. In bivalves, the highest average concentration of the 3-ring compound Acenaphthene with an average (ppb) of 1261 and the lowest value of the 6-ring compound Benzopyrylene with an average (ppb) of 32 were obtained. The highest average concentration of the 4-ring compound Fluranthene with an average (ppb) of 1551 and the lowest value of the 6-ring compound Benzopyrylene with an average (ppb) of 0 was obtained in crustacean tissue.
Conclusion: Findings have shown that sediments absorb 5-ring compounds, molluscs absorb 3-ring compounds, crabs absorb 4-ring compounds, and reptiles absorb 5-ring compounds more easily.
