The mass death of marine life on the coastline from Hartlepool to Whitby saw swathes of crabs washed ashore between October and December 2021.
An independent panel concluded it was"exceptionally unlikely" that dredging to expand a Teesside port caused the deaths of thousands of crabs and other marine life.
Mass deaths of the animals on the coastline from Hartlepool to Whitby saw swathes of crabs washed ashore between October and December 2021.Fishing crews also warned that the event was"catastrophic" for their livelihoods. Academic research suggested the deaths were caused by industrial pollutant pyridine, possibly from dredging in the mouth of the River Tees to maintain channels for port traffic.
But the independent panel, made up of academics, industry experts and chaired by the Department for Environment, Food, and Rural Affairs' chief scientific adviser Gideon Henderson, found that it was"very unlikely" the cause of death was pyridine or another pollutant. Researchers from the Environment Agency and York University did not detect pyridine in the seawater, and toxic chemicals found in the River Tees were"significantly lower" than what would cause crab mortality, the panel said.

Rac1 controls cell turnover and reversibility of the involution process in postpartum mammary glandsCell turnover in adult tissues is essential for maintaining tissue homeostasis over a life span and for inducing the morphological changes associated with the reproductive cycle. However, the underlying mechanisms that coordinate the balance of cell death and proliferation remain unsolved. Using the mammary gland, we have discovered that Rac1 acts as a nexus to control cell turnover. Postlactational tissue regression is characterised by the death of milk secreting alveoli, but the process is reversible within the first 48 h if feeding recommences. In mice lacking epithelial Rac1, alveolar regression was delayed. This defect did not result from failed cell death but rather increased cell turnover. Fitter progenitor cells inappropriately divided, regenerating the alveoli, but cell death also concomitantly accelerated. We discovered that progenitor cell hyperproliferation was linked to nonautonomous effects of Rac1 deletion on the macrophageal niche with heightened inflammation. Moreover, loss of Rac1 impaired cell death with autophagy but switched the cell death route to apoptosis. Finally, mammary gland reversibility failed in the absence of Rac1 as the alveoli failed to recommence lactation upon resuckling.
