Petroleum hydrocarbons - a necessity of monitoring in a dredged material in the Polish coastal zone
Journal Title: Biuletyn Instytutu Morskiego - Year 2018, Vol 33, Issue 1
Abstract
Petroleum hydrocarbons (PHCs) are toxic for the water organisms and may last for a very long time in sediments. The Baltic Sea is an area exposed to PHCs due to highly developed shipping. In Poland, there is lack of legal standards specifying guidelines regarding handling dredged material containing PHCs, excavated in waterways, roadsteads, and in port basins, and there are no standards specifying their acceptable concentration in sediments. Therefore, petroleum hydrocarbons in the excavated dredged material are rarely examined at the Polish coasts. In years 2009-2018 only 4% of sediments were examined in terms of their content. Studies indicated that only sediments from the open sea did not contain PHCs, , while others were very or moderately contaminated with PHCs. The collected results clearly indicate that sediment should be monitored in terms of PHC content; in most cases, it should not be thrown back to the sea. It may usually be stored onshore, but only on wastelands, mainly in industrial and transport areas. Some sediments may also be used within clearer lands, i.e., forests wood- and bush- -covered lands, recreation and leisure areas.<br/><br/>
