Oil spills are serious environmental issues that potentially can cause adverse effects on marine ecosystems. In some areas, like the Baltic Sea, there is a large number of wrecks from first half 20th century, and recent monitoring field work have revealed release oil these wrecks. The risk posed by wreck governed its condition, hazardous substances contained in state surrounding environment. Therefore, need for common standard method estimating risks associated with different this...
Shipwrecks deteriorate and the probability of a release oil increases with time on sea floor. The potential leakage is risk to marine environment may also have social economic consequences. purpose this study was evaluate existing methods for assessment shipwrecks suggest generic framework. A necessary providing decision support remediation actions thus enabling an efficient use available resources. Existing aimed assessing were evaluated by comparison relevant parts international standard...
How zinc oxide influences copper release has been tested and the lowest rate of from various combinations in a paint matrix evaluated, whilst still deterring macrofouling, including barnacles bryozoans. Copper (I) was added to generic AF 0, 8.5, 11.7 or 16.3 wt% combination with 10 20 applied on PMMA panels. The results show that copper. When added, total amount released significantly increased by average 32 47% respectively. All treatments included were successful treatment Cu rate, ie 4.68...
We describe the effect of eight different imidazoline/guanidinium compounds on settlement and metamorphosis larvae barnacle Balanus improvisus. These agents were chosen basis their similar pharmacological classification in vertebrates chemical similarity to medetomidine clonidine, previously described as highly potent inhibitors (nanomolar range). Seven tested found inhibit a dose-dependent manner concentrations ranging from 100 nM 10 µM without any significant lethal effects. In vertebrate...
A novel, non-toxic strategy to combat marine biofouling is presented. The technology paint with additions of up 43% industrial protein. Through microbial degradation the protein component, an oxygen-depleted layer rapidly forms in a 0.2 mm close surface. With present formulations, stable, O2-depleted can persist for 16 weeks. Barnacle larvae (cyprids) did not settle on panels where oxygen saturation was <20%, and cyprids were killed when exposed O2-free water more than 1 h. It also shown...
The ability of marine microbes to develop tolerance polycyclic aromatic hydrocarbons (PAHs) was examined in a 90-day experiment. PAH levels sediment were increased 0.3 and 1.6 times compared the control sediment. Day 30, 60 90 re-exposed PAHs short-term toxicity test detect tolerance, where nitrification denitrification used as endpoints. In addition, molecular analysis microbial communities performed possible differences proportions nitrifying bacteria total bacterial abundance...
