Download MS PowerPoint Slide To reduce sulfur emission from global shipping, exhaust gas cleaning systems are increasingly being installed on board commercial ships. These so-called scrubbers extract SOX by spraying water into the exhaust gas. An effluent is created which is either released directly to the sea open-loop system or treated to remove harmful substances before release closed-loop system.
Introduction
We found severe toxic effects in the ubiquitous planktonic copepod Calanus helgolandicus of exposure to effluents from two closed-loop systems and one open-loop system on North Sea ships. The effluents contained high concentrations of heavy metals and polycyclic aromatic hydrocarbons PAHsincluding alkylated PAHs. We observed significantly elevated mortality rates and impaired molting already in the lowest tested concentrations of each effluent: 0. These concentrations correspond to total hydrocarbon concentrations of 2.
None of the individual PAHs or heavy metals analyzed in the effluents occurred in concentrations which could explain the high toxicity. Introduction Jump To Atmospheric emissions from ships in international traffic are often high compared to emissions from other transport modes. Less stringent regulations on sulfur content and lesser use of exhaust after-treatment on ships result in higher emissions of SOX, NOX, and particles from combustion of marine fuels. Scrubbers extract SOX by spraying water into the exhaust gases before emission. Besides SOX, a wide And of other harmful substances, such as toxic hydrocarbons and heavy metals, are removed from the exhaust gas and instead released directly to the sea.
The Importance Of Being A Doll 's House
Many fish species spawn in the nearshore environment. This is also where they spend their larval and juvenile life, a period in which they are most vulnerable to negative effects from pollution. By their grazing on microplankton, they are the main conveyors of energy from lower trophic levels to the upper marine food web, and they form the bulk of the diet of many larval and juvenile fish, thereby supporting global stocks of many fish species.]
The excellent answer
Here there's nothing to be done.
You are not right. Let's discuss it.
I consider, that you commit an error. I can defend the position. Write to me in PM, we will discuss.
