Research Shows Lead Ocean Pollution Drops

first_imgNew research shows the first observed reduction in lead concentrations in the surface waters of the seas around Europe since the phasing out of leaded petrol.Lead has no biological function, and is toxic to humans and marine organisms. The study, published in Geophysical Research Letters, is based on samples of the Celtic Sea taken during a series of research expeditions on board the Royal Research Ship (RRS) Discovery.The results show that there has been a four-fold reduction in the concentration of lead in the surface waters of European shelf seas compared to measurements undertaken two to three decades ago, following the phase-out of leaded petrol in Europe over the same time period.This finding is the result of an international collaboration by researchers from the National Oceanography Centre (NOC), GEOMAR (Germany), the Universities of Edinburgh, Southampton, Plymouth (UK) and Bretagne Occidentale (France), NIOZ (Netherlands) and Lawrence Livermore National Laboratory (USA).Stricter environmental regulations have reduced lead emissions into the environment, and leaded petrol has now been almost entirely phased out in the UK. Yet, prior to this change, enhanced lead emissions from human activity occurred for more than 150 years, and resulted in oceanic lead concentrations up to 100 times higher than natural background levels.Lead deposited in the ocean is later transferred to sea-floor sediments. The results of this study show that ‘legacy lead’ is now being released by sediments, forming a new lead source to the environment. Historical lead signals are also evident in deep Mediterranean waters around 1000 metres deep, transported from the surrounding countries of Italy, Spain and Greece, where leaded petrol was only phased out in 2003.Professor Eric Achterberg from the University of Southampton, said: “Our results show that sediments have become a source of lead to overlying waters. The lead in sediments represents the legacy of lead supplied to the sea over the last 150 years. This was not expected, as lead is assumed to bind very strongly with particles in the seas and thus remain permanently trapped in the sediment. Our thinking on this needs to be re-assessed, and lead concentrations will likely take much longer to return to natural background levels in coastal waters than previously anticipated.” Professor Douglas Connelly from the NOC added: “the behavior of trace elements in the oceans is far more complex than previously expected, and emphasizes the need to better observe the oceans.”Dr Martha Gledhill from GEOMAR, said: “The sampling and analysis for lead in seawater is challenging, and has only been possible since the 1980’s. The challenges are related to the relatively low concentrations of lead in seawater. The sampling has to be conducted using metal-free specialized equipment, in order to exclude contamination from sampling equipment. Sampling is a challenge because lead is found almost everywhere on ships—even on new plastic surfaces. Analysis has to be conducted in specialized clean-rooms, similar to the ones that computer chips are manufactured in.”This research was conducted as part of the UK Shelf Sea Biogeochemistry Programme and the International GEOTRACES Programme. At numerous sites in the Celtic Sea, Dagmara Rusiecka, a PhD student from the NOC who is working on this project, took water samples for measurements of lead, which were then taken to specialist laboratories at GEOMAR for analysis.Professor Eric Achterberg continued: “The lead data from this study are an important contribution to the GEOTRACES Programme —a large international effort to map metal concentrations in the global ocean. The data will allow us to make larger scale predictions about contaminant transport in shelf seas. Ultimately, combining such information with worldwide contaminant metal measurements and improvements in ocean models will enable us to make robust predictions about pollutant behavior and effects on ecosystems at a global scale. “Source :NOClast_img read more

Infantino to ‘respect’ any ethics committee decision – FIFA

In total, more than 20 FIFA proceedings have been opened in Switzerland over the past five years into allegations of corruption and vote-buying, and allegations over the awarding of television rights contracts. FacebookTwitterWhatsAppEmail分享 FIFA president Gianni Infantino will “respect any decision by the ethics committee”, world football’s governing body said Monday after Swiss authorities opened criminal proceedings against him last week. A Swiss special prosecutor has launched proceedings against Infantino, as part of an investigation into suspected collusion with the country’s attorney general, Michael Lauber. Both have denied any wrongdoing. “I’ve no doubt that Gianni Infantino would respect any decision by the ethics commission,” FIFA deputy secretary general Alasdair Bell told a video news conference. “We don’t see any evidence of criminal or unethical behaviour,” he said. FIFA on Sunday insisted Infantino would continue to fulfil his duties as president and blasted the Swiss probe. It gave no indication on Monday whether or not its ethics committee had instigated proceedings against Infantino. “The ethics committee will have to come to its own conclusion… In every case, it needs to be tested, if there’s something serious, there’s a case for suspension,” said Bell. Questioned about Infantino’s absence during Monday’s video conference, Bell said the FIFA chief “will be available and will speak in order to clear his name.” He added: “FIFA and Gianni Infantino have absolutely nothing to hide, we want to be transparent. There’s no factual basis for this criminal procedure.” Infantino and Lauber are said to have held a series of meetings in 2016 and 2017. Two such meetings were initially exposed in 2018 by “Football Leaks”, a cross-border investigation by several European news organisations. In a statement Thursday, Swiss authorities said special prosecutor Stefan Keller “has reached the conclusion that…there are indications of criminal conduct” in relation to meetings between Infantino, Lauber and another official, Rinaldo Arnold. “This concerns abuse of public office, breach of official secrecy, assisting offenders and incitement to these acts,” the authorities said. Lauber, who offered his resignation on July 24, was in charge of Switzerland’s probe into the towering corruption scandal that exploded at the heart of Zurich-based FIFA in 2015. But he was forced to recuse himself from the investigation in June 2019, following media revelations that he had held several undeclared meetings with Infantino during the probe.last_img read more

MINISTER FAILS TO ACKNOWLEDGE SAFETY ISSUE IN DONEGAL BUS ROW – McCONALOGUE

first_imgDeputy Charlie McConalogue has slammed the Government for refusing to accept that the road Bus Eireann is using to calculate the nearest school route for Urris pupils is unsuitable and unsafe.Charlie McConalogue TDDeputy McConalogue yesterday challenged the Education Minister in the Dáil on the issue.However although Minister Jan O’Sullivan said she was aware of the issue she also stated that the criteria in determining school transport eligibility had to be applied uniformly across the country. “The Minister’s response is clear – this Government is going to force pupils from the Urris area to travel across a dangerous mountain road and relocate from Carndonagh to Buncrana if they want to avail of free school transport”, explained Deputy McConalogue.The change in school transport eligibility came into effect in September 2012 however with the introduction this year of online registration and the use of google maps to determine distances it is now coming to light that the nearest school for Urris pupils is Buncrana because the online system uses Mamore Gap when calculating the shortest route.The Donegal Deputy commented, “This new system is completely senseless. Not only does it advocate the use of the road through the Mamore Gap, which is extremely treacherous during the winter months, it will see children from Urris forced to relocate from Carndonagh Community School to Buncrana. This has the potential to lead to a situation where two siblings are attending two separate schools in different locations, as the new rules only came into force in September 2012.“There is a long tradition of children from the Urris area attending Carndonagh Community School and I am extremely concerned that the system used to calculate the distance does not take the condition of the route in question into account. Bus Eireann has decided to use a road through Mamore Gap in calculating one of the routes, despite the fact that the road itself is dangerous, particularly in the winter months, and could put the safety of these children at risk. Despite the concerns raised by local parents, Bus Eireann claims the rules given to it by the Department of Education is prohibiting it from ruling out this option. “The Minister of State with responsibility for school transport Damien English washed his hands of the situation in the Dáil yesterday when he passed the buck back to Bus Eireann, stating that responsibility for the planning and timetabling of school transport routes rests with the bus company, as it operates the school transport scheme.“I have been working on this issue with both Councillor Martin McDermott and Councillor Rena Donaghy and I will continue to raise this issue directly with the Minister. This is a completely unacceptable situation and I will not let this matter rest. The Minister O’Sullivan must allow Bus Éireann to apply a sensible and safe approach to this situation so that the students of Urris can continue to attend the Carndonagh Community School”.MINISTER FAILS TO ACKNOWLEDGE SAFETY ISSUE IN DONEGAL BUS ROW – McCONALOGUE was last modified: April 23rd, 2015 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)last_img read more
