Pyridine and North East England contamination

Dead crabs and other marine life

The information on Pyridine states:

“Pyridine appears as a clear colorless to light yellow liquid with a penetrating nauseating odor. Density 0.978 g / cm3. Flash point 68 °F. Vapors are heavier than air. Toxic by ingestion and inhalation. Combustion produces toxic oxides of nitrogen.CAMEO Chemicals

Pyridine is a colorless liquid with an unpleasant smell. It can be made from crude coal tar or from other chemicals. Pyridine is used to dissolve other substances. It is also used to make many different products such as medicines, vitamins, food flavorings, paints, dyes, rubber products, adhesives, insecticides, and herbicides. Pyridine can also be formed from the breakdown of many natural materials in the environment.CDC-ATSDR Toxic Substances Portal

Pyridine is an azaarene comprising a benzene core in which one -CH group is replaced by a nitrogen atom. It is the parent compound of the class pyridines. It has a role as an environmental contaminant. It is a mancude organic heteromonocyclic parent, a monocyclic heteroarene, an azaarene and a member of pyridines.ChEBI”

The region is experiencing a push just now as aBrexit inspired ‘Freeport’ and dredging is part of the preparation:

Consider the facts around dredging:

“Dredging is the act of removing silt and other material from the bottom of bodies of water”

https://oceanservice.noaa.gov/facts/dredging.html

In the case of the river Tees, a site of centuries of toxic waste allowed to pollute the river when there was no regulation, and so all life in the river died.

Able-UK dredged, 2014

To clear out the silt, dredging began in 2014:

The work of dredging has to be maintained to keep the port clear:

According to noaa.gov:

“Dredging is also performed to reduce the exposure of fish, wildlife, and people to contaminants and to prevent the spread of contaminants to other areas of the water body. This environmental dredging is often necessary because sediments in and around cities and industrial areas are frequently contaminated with a variety of pollutants. These pollutants are introduced to waterways from point sources such as sewer overflows, municipal and industrial discharges, and spills; or may be introduced from nonpoint sources such as surface runoff and atmospheric deposition”

In which case, if this was environmental dredging, the contaminants should not have entered the North Sea, but should have been safely disposed of where toxins could not even enter groundwater.

Teesside was famous for steelmaking, plus many other industries which made the air above a yellow smog for decades:

The answer to this poisoning of marine life must be found and action taken to protect sea life in future from whatever mistaken error was made in this instance.

If the cause was not dredging, then it might have been a virus:

And then, as Teesside is one of the new Freeports, we must ensure strict biosecurity:

How did a new pathogen arrive in these waters?:

Retired, living in the Scottish Borders after living most of my life in cities in England. I can now indulge my interest in all aspects of living close to nature in a wild landscape. I live on what was once the Iapetus Ocean which took millions of years to travel from the Southern Hemisphere to here in the Northern Hemisphere. That set me thinking and questioning and seeking answers. In 1998 I co-wrote Millennium Countdown (US)/ A Business Guide to the Year 2000 (UK) see https://www.abebooks.co.uk/products/isbn/9780749427917
