Summary: The environment in which people live and work has
limitedpotentials and resources. The interaction between industrialobjects,
energetics, marine technology structures and environmentcauses harmful
consequences on the environment. A lot of factorshave been studied during
the analysis of effects of marinetechnology structures on the environment,
but it is of greatimportance to know the mode of detection and the motion
of traceelements in environment, since they are important both for
livenature and for the processes in extinct segments which be
morethoroughly studied. The measuring technique will be X rayspectroscopy,
polarometry and UV spectroscopy.
Keywords: Marine technology structures, X ray, polarometry, ultraviolet spectroscopy, environment.

Summary: The interaction between industrial objects, energetics,
marinetechnology structures and environment causes harmful consequenceson
the environment. It is important to know the change in theconcentrations of
trace elements, especially heavy metals. Themethod of polarographic
analysis applied in the analysis of toxicmetals in aquueous solutions is
described. This method has alarge range of applications, particularly for
the analysis oftraces in aqueous solutions. Possibilities of these method
are inthe field of toxic metals determination. Limits of detection areoften
extremly law. The measurements have shown that very lowconcentration of
toxic metals in sea water, such as zinc, leadand cadmium can be detected.
Keywords: Marine technology structures, polarometry, trace elements, environment, sea water

Summary: The fluorescence spectroscopy is used as a method
ofidentification of the mineral oil pollutanzs on the sea
surface.Fluorescence spectra of oil solutions in different
solvents(benzene, hexane, cyclohexane, isooctane, xylene, toluene) havebeen
measured. In a chosen solvent, spectra of various oils atconstant solution
concentration have been recordered. Theinfluence of oil concentration on
fluorescence spectra have beenalso examined.
Keywords: Fluorescence spectroscopy, pollutions, mineral oils

Summary: The subject of this paper is interaction of maritime
objects,particulatly of marine technology structures with environment.The
exploitation of these structures in natural environment hasas its
consequence zje impact on environment, especially on thesea, so that its
elemental condition is changed. Characteristicsand possibilities of
applying several methoda for defining andanalyzing of trace elements
concentration especially metals inthe sea, are elaborated. The focus is on
the aspect of the X rayspectroscopy and polarometry.

Summary: The information concerning the effect of used motor oils on
the soil and equatic environment are discussed. In contrast to crude oil
pollutin, used motor oil pollutin is world wide, becouse the major sources
are automotive traffic and industrial activity. Used motor oils are very
dangerous polluting products. They contain polynuclear aromatic
hydrocarbons and havy metals such as Pb, Zn, Cu, Cr, Ni and Cd at high
levels. These metals are highly tocsics to living organisms.
In this work, the concentration levels of additive metals: Zn, Ca and Mg as
well as the metals from fuel: Pb, V and Ni, and from motor wear: Cr, Fe, Cu
and Cd are discussed.
Keywords: environment, havy metals, motor oils, AAS
