NEWS RELEASE Wednesday 4th June, 2008.
HEAVY METAL ROCKS DERBYSHIRE RIVER
A scientific report has found that heavy metals have begun to accumulate in the food chain in parts of the River Derwent in the Peak District National Park, Derbyshire, following a pollution incident last year. In January 2007, a settlement lagoon owned by Glebe Mines burst, discharging volumes of sediment into the Derwent via one of its tributaries, the Stoke Brook. The sediment was contaminated with mine tailings - fine waste material - which included arsenic, cadmium, lead and other metals. The report commissioned by the Anglers' Conservation Association (ACA) warns that lead levels in insects from the impacted areas are significantly elevated and there is a high risk that the levels in fish may rise. Over time, the range of elevated metals may pose a threat to the fish and the ecosystem, as well as exceeding the recommended safe lead limit for human consumption. Dr. Nick Everall, the Aquatic Ecotoxicologist who conducted the survey on behalf of the ACA and the fishing clubs, said: "I conservatively calculated from lead levels in invertebrates that there was a high risk of the fish tissue samples exceeding lead guidelines for human consumption. Some other metals which remain in the sediments and the fly life were also above background levels, but not as marked as the lead concentrations."
An Environment Agency (EA) report published shortly after the pollution suggested that prompt action was needed to minimise the damage caused and that there should be proper investigations and monitoring of the heavy metals in the sediment deposited in the river. However, the EA sampling that has taken place has been so limited that the ACA was forced to instruct its own expert. The trial remediation work is due to begin in June 2008, almost 17 months after the pollution. Dr. Justin Neal, solicitor for the ACA said: "When a pollution of this magnitude occurs, one would expect the statutory body charged with the enforcement and regulation of environmental matters to act swiftly in investigating and then using its powers to remediate the problems. However, it appears that although it was initially quick to instruct its own expert, the Agency was then content to sit back and let the insurers for Glebe Mines sort out the problems. 17 months on, we are without a full investigation into the heavy metals levels in the fish and the remediation is yet to begin. This is not a satisfactory state of affairs."
Mark Lloyd, the ACA's Executive Director added: "The ACA's members who fish on this river are understandably exasperated by the way in which the Environment Agency has handled this incident. Quite apart from the damage to the invertebrate and fish life in the river, there are very real implications for the health of any anglers who might have taken fish to eat. The Agency's response to the ACA's demands for action has been desultory."

Notes for Editors:
1) The heavy metals of most concern to human health are mercury, cadmium and lead. Heavy metals suppress the immune system, leading to increased susceptibility to disease in animals (Mason, 1996). Fish are particularly susceptible to immune system suppression by a wide range of heavy metals (O' Neill, 1981). Heavy metals may also be carcinogenic (Peakall, 1992).
2) The ACA was founded in 1948 with the purpose of using the law to fight to protect the aquatic environment and fisheries. Since then, the ACA has won or settled over a thousand cases and recovered many millions of pounds in damages, which is returned to the members represented to plough back into angling and the protection of the aquatic environment. Only three cases have ever been lost at trial. Clubs or riparian owners wishing to join the ACA should phone 01568 620447 during office hours or download a subscription form from the web site: www.a-c-a.org
3) The River Derwent is approximately 50 miles in length and is the largest river of the Peak District, the most visited national park in the U.K. and the second most visited in the world. It flows through mostly rural countryside, except for a short section through Derby. The Derwent joins the River Trent just south of Derby.
