Marine logistics companies must follow environmental requirements, which are regulated
by international ISO standards. Environmental problems concern among others: protection
of oil terminal basins, safety in port, pollution generated during cargo handling, industrial
pollution, in that storage and utilisation of wastes. In the paper reference is made to the
works of the European Sea Port Organization and to international law developed by IMO.
Logistics companies’ environmental interests are focused on atmospheric air protection,
water protection, protection against noise, waste management and rational use of natural
resources. First of all, dust concentration is generating in seaport territory and lately it can
be easily blown by the wind to urbanized areas, regional parks or together with wastewater
access to surface waters. According to legal act’s rules, logistics companies have to make
accounting and control of capture emissions of substances and pollutants.

According to the statistics data (fig. 3), it was found, that from one of the largest cargo
handling companies which are located in port of Klaipeda the emission of pollutants almost
reached 7,2 tons per one year, and the most part of these pollutants was in dust shape. It is
important to assess the factor that port of Klaipeda is located in the urbanized territory. The
port is also located near The Curonian Spit (Kuršių Nerija) which are in the part of the
UNESCO heritage list, so the environmental problem is particularly relevant, because water,
ecosystem even local people can be easily contaminated by chemicals which are abundant
in the dust concentration. Dusts, as well as other pollutants released into the environment
are characterized by the risk of a negative impact on the environment by chemical, physical
or biological materials, also pollutants as dust are characterized by a relatively high stability
and longevity in the environment. Dusts are applied to the factor of pollutant dispersion.
Pollutants of dusts released into the environment are circulating in different components of
the environment together affecting all the components involved in circulation (figure 4). The
factor of dusts dispersion and distribution is determined by particle size and physical
contaminants form (solid or liquid particles adsorbed on the surface of solid particles) and
the speed of movement – meteorological phenomena. Usually during calm weather there is
another problem with dusts when the most part of them are concentrating in one area and
with this action the environmental pollution by particulate matter are increasing extremely
fast. Depending on the cargo type it depends what kind dispersion of dust circulation are
going to exists.
