The competitive advantage of the passenger air transport market is a significant part of airline operations. An important element, a condition that may determine the achievement of competitive advantage, is the issue of safety, which also applies to the operation of aircraft. An example of creating an effective competitive advantage may be the operation of a new aircraft by air carriers. This article presents the process of creating a competitive advantage on the example of the Airbus A350 XWB and the Boeing 787 Dreamliner aircraft considering the safety aspect, which in the case of new means of transport in civil aviation may primarily concern the seeming childhood diseases occurring in the initial use of new aircraft. This article, in the form of comparative analysis, indicates the key features that determine the attractiveness of the new aircraft as a product on the passenger air transport market. Secondary data on the characteristics of the Airbus A350 XWB aircraft were used and compared with the data of the Boeing 787 Dreamliner to illustrate the properties that may indicate the manufacturer's superiority. Furthermore, this article proposes a scheme of creating competitive advantage in passenger air transport, which can be a model for creating a competitive advantage in civil aviation. The close relationship between the economic and technological aspects in creating competitive advantage was buttressed as well. This article also analysed secondary data related to the numer of ordered and used aircraft and aviation events registered on the website: https://aviation-safety.net [8], which could have an impact on the level of safety of flight operations. Brought to the fore were situations in which the seeming childhood diseases in aircraft operated by the American manufacturer, Boeing 787 Dreamliner, such as defects in engines, power elements and risks associated with the use of composite materials, which were first used on such a large scale in the construction of wide-body aircraft.

The chemical composition of surface waters of the Przemsza River flowing through Upper Silesia (in southern Poland) is strongly affected by Zn and Pb ore, and less by Carboniferous hard coal deposits. The chemical type of surface water is Ca-HCO3. In the waters, three groups of metals and metalloids were found that directly interfere with the mineralization of the deposit. Although genetically related to the same deposit, each group exhibits a different fate in the environment. A typical deposit association is Pb-Zn-Ag-As-Sb-Hg. The first group of metals in surface waters is consistent with the typical association of the ore Zn-Pb-Cd-(Tl), the second includes Ag-Sb-Hg, and the third includes the additives in the zinc and lead ore Co-Ni-Mo-Mn: [formula]. Depending on the pH-Eh conditions, metals and metalloids precipitate out of the solution or sorb on solid particles. The concentrations of individual groups of metals are interdependent but show different environmental fates along the river course. The natural process of the enrichment of surface waters with Zn-Pb-Cd-(Tl) is by water circulation in a rock matrix naturally rich in the metals and draining groundwaters by the river. Under oxidizing and slightly alkaline conditions, Ag-Sb-Hg incorporated into the soluted chemical compounds, may, when the physicochemical parameters of the waters change, be adsorbed and/or precipitated. The presence and ratio of concentrations of Co-Ni-Mo-Mn with respect to zinc are almost identical, differing only in concentration.
