In the last century, in the Baltic Sea region located many wrecks defaulting at the bottom of the basin - remnants of World
War II. Sunk with a cargo of both warfare agents, ammunition or fuel, represent a real threat to the marine ecosystem.
Systematically releasing substances from defaulting construction, are significant point sources of pollution in the Baltic Sea
region. In 2015 and 2016, samples of bottom sediments were taken in the area of the wreck ORP Wicher. They were subjected
to grain size analysis , content of organic matter, as well as examined the content of petroleum substances and the massive
magnetic susceptibility. The samples were preserved by freezing, until analysis. All tests were performed in accordance with
the standards for marine sediments (US EPA), and with at least 3 repetitions. To fluctuations in studied parameters primarily
affects the location of the wreck –area of strong currents activity and the depth of 5-17m. The value of measured parameters in
the samples primarily depended on the deposits grain sorting. Analysis of magnetic susceptibility showed that higher values
were recorded with an increase in the share of the fine fraction <0,063mm [%] and organic matter LOI [%]. In the samples
was measured the content of petroleum substances. Based on the results of concentrations of the test substances, the magnetic
susceptibility and the coefficient fd [%], it can be estimated that the wreck is a point source of pollution in the Gulf of Puck,
which with time can be transported for longer distances.
