Environmental organizations and UK authorities assess the extent of destroying the collision of the oil tanker and a shipping ship in the North Sea will be for marine species and population in near wildlife.
It is still too early to know if it will have a major impact, and the weather conditions in the coming days will be a major factor.
But many will depend on any toxic chemicals that have been spilled and the amount.
What may be on board?
The marine operations company, Crowley, which was running the oil tanker The MV STANA EMMACULATE, confirmed that it carries 220,000 barrels of jet fuel at 16 containers at the time of the accident.
It was not clear about the condition of all containers, but Crowley said that one of them was “torn” and was leaking from the sea.
The contents of the shipping ship, Solong, which were shattered in the carrier are less clear.
Lloyds List, a shipping data company, said on Monday that it carries sodium cyanide.
But on Tuesday, Ernest Ross, the owners of the shipping ship, said: “We are able to emphasize that there are no containers on board with sodium sodium.
“There are four empty containers that previously containing the dangerous chemical and these containers will continue to be monitored.”
It is still unclear whether the ship carries other contents at the time of the accident.
What are the risks of jet fuel and sodium?
Jet fuel is a toxic substance that can be fatal to marine organisms and other animals such as marine birds if eaten.
The level of toxicity depends on the crude oil from which it was refined.
Sodium cyanide, which is used in industry including mineral cleaning, is also a toxic substance for living organisms because it disrupts the cell function and leads to hunger.
Sodium cyanide is also very soluble in water and can interact strongly for the production of gas hydrogen gas – which is also toxic.
Emphasizing that only empty containers on the plane would calm some concerns about environmental damage and make the cleaning process easier.
The third consideration of the authorities will be whether the fuel used to run both ships – the cellar fuel – may also leak.
Marine fuel is much heavier than jet fuel and can remain in the environment for a longer period.
Alex Lukianov of the University of Reding, UK, said. “Marine diesel can strangle wild habitats and wildlife, which affects its ability to regulate the body temperature, which may lead to death.”
“The environmental losses can be severe,” he said.
“There is no evidence so far on any heavy engine oil leaks from any of the ship,” said Graham Stewart, local deputy of Peverley and Holders. But he added that this is still possible.

What mitigation can be taken?
The Branch of Marine Accidents Investigation supervises the operation to respond to the accident and clean any pollution.
Melanie On, the deputy of Great Grimsby and Cleithorpes, told BBC Radio 4 today that Maritime and Coastguard (MCA) are currently evaluating pollution risks and working with both the owners of savings to plan a rescue process.
“The priority is imagined, because the crews trying to contain damage are to extinguish fires and maintain the vessels on his feet. This will reduce the amount of chemicals that enter water and the risk of wildlife down,” said Professor Alceter Hi, Professor of Honorary Environmental Poison Science at Leeds University.
The fire that broke out after the accident will help burn some jet fuel, but test groups are set on the site to confirm the absence of residue.
FRODE VIKEBU, Director of Research at the Marine Research Institute, said that the UK government will mix the spread of any pollutants at sea, taking into account the circulation of oceans and weather conditions, as part of the “standard measure”.
With regard to mitigation, Dr. Karen Burnil, former director of ITOPF – who advises governments on marine pollution, said the first approach is to allow jet fuel “naturally dispels where possible and avoid deliberate containment.”
If any jet fuel has made the beach, she said: “Wiping the coastal line to rejuvenate fuel and may be directed to mutations or absorbent mats to get rid of disposal of it may be an option.” But she said that the approach will differ depending on the different types of environment, for example if there are wet lands.

What is the wildlife that might be affected?
The collision occurred inside an environmentally rich area – both for marine species and also groups of wild birds that feed on fish or other aquatic organisms.
Humber Estuary is a special scientific interest, in addition to the Bempton Cliffs Nature Reserve supports more than half a million birds annually including geese with pink feet, misery, languages and tail lodes.
Within the broader maritime environment at this time of the year, there are raising seals and a port of pigs.
Martin Slater, the director of operations at Yorkshire for wildlife, said that the time of the year in which this spill occurred is particularly concerned.
He said: “Many birds gather outside on the sea before the nesting season and we still have properties in the winter – in addition to that migratory birds stop here – so we are very concerned about the threat of these birds.”
There is also anxiety of wildlife south of the accident in which jet fuel may spread depending on wind and sea conditions.
Mr. Salter explained that the area off the Lincolnchyer coast is “a unique homeland of fish where marine birds and cyttakan feed.”
Environmental experts indicated that animals have reactionary mechanisms that mean the noise and the smell of the accident had been raised to the risks and that they had already created the area.
