While some people are disgusted by the thought of human pee in their pool water, others figure there’s no harm in letting loose a little urine while swimming. It turns out, however, that when urine reacts with chlorinated water, it may be creating chemical byproducts hazardous to everyone in the pool.
Cyanogen chloride (CNCl) and trichloramine (NCl3) are nitrogen-containing disinfection byproducts (N-DBPs) that are commonly found in swimming pools. In low levels, N-DBPs have been linked to eye and throat irritation, and in high levels, they have been linked to nervous and cardiovascular problems. It turns out that this toxic swimming pool environment may be caused, at least in part, by swimmers peeing in chlorinated pools.
A study authored by researchers at China Agricultural University and Purdue University and published in Environmental Science and Technology looked at the reactions between chlorinated water and uric acid and found that mixing the two produced both cyanogen chloride and trichloramine at varying levels, depending on the ratio of the precursors, the pH of the water, and the temperature of the water. They also looked at swimming pool water that already contained cyanogen chloride and trichloramine and added more uric acid, and found that the levels of cyanogen chloride increased with the addition of uric acid, although the levels of trichloramine were not so predictable. They concluded that the chlorination of uric acid may be responsible for much of the formation of cyanogen chloride in swimming pools, and perhaps, to a lesser extent, for the formation of trichloramine.
So what’s the point of this wee research? Since urinating in pools is, for most swimmers, a voluntary action, perhaps encouraging swimmers to practice better urinary hygiene could improve the environment of chlorinated pools, making them a little less irritating to our various systems. Of course, this particular study only covers swimming in chlorine—you’ll have to look elsewhere for verdicts on peeing in natural bodies of water.
New Zealand’s top swimmers are putting in some serious yards ahead of the national champs early next month.
The 11-strong squad is into the final week of a month long altitude training camp in Flagstaff, Arizona, with the facility at 2100 metres.
With the nationals also doubling as the Commonwealth Games trials, coach David Lyles says they’re doing about 12 sessions a week.
Lyles says the swimmers have done much better than when they went to Sierra Nevada last year.
“You have to be a lot more careful in the planning for sure. We’ve had to make a couple of little changes, nothing too major, but we’ve had to just switch a couple of sessions here and there just to allow them a bit more recovery.
“But they’ve coped real well, they’ve been doing some real good work.”
The team will return on Tuesday, giving them three weeks to be ready for the trials.
Global swimwear brand Speedo has been announced as the official product and swimwear provider to the Spanish Swimming Federation (RFEN) in a new three-year deal.
Speedo will provide equipment and apparel for all RFEN athletes competing in swimming, water polo, diving, synchronised swimming and open water disciplines until December 2017.
The deal will take in all major international events including World Championships and the Rio 2016 Olympic Games.
“Speedo and the Spanish Swimming Federation have enjoyed a long relationship spanning almost two decades,” said vice-president of products and marketing at Speedo International Sean Hastings.
“The Federation is home to some of the highest performing athletes in the world and we are proud to be able to support them at all their upcoming tournaments, including the 2016 Olympic Games in Rio.”
At last year’s FINA World Championships in Barcelona, hosts Spain picked up 12 medals including a gold for the women’s water polo side, three silver and four bronze in synchronised swimming, and two silver and two bronze in swimming.
That followed on from five medals at London 2012 that included a double silver for 23-year-old swimmer Mireia Belmonte Garcia, as well as a silver in the women’s water polo competition.
Spanish swimmers will showcase the latest Speedo products and equipment at the upcoming LEN European Swimming Championships in Berlin, Germany which are due to run from August 13 to 24, followed by the FINA World Swimming Championships in Doha in December.
Last year, Speedo announced a similar deal with the China Swimming Association which will see all Chinese swimmers use its products up to and including the 2017 World Championships in Guadalajara, Mexico.
“After the withdrawal of Algeria, the Confederation of African Swimming (CANA) designated Senegal to host the next African Championships swimming planned for next September, ” the president of the Senegalese federation told Africa Top Sports.
According Dr. Mohamed Diop : “It is Algeria, which was to organize these games, but for some reasons, the Confederation has appointed Senegal. A proposal we accepted by the Steering Committee and the General Assembly.
“This organization does not have only sporting interests, but will also massify the discipline.”
An organization that comes at a crucial moment in the life of the Senegalese swimming suffering serious lack of infrastructure.
Indeed, during the last season there were throughout the Senegalese capital only one 25 meter pool located in a French military base.
Other Olympic swimming pools were being renovated. Their provision is probable this year.
A recall that this information was revealed on the sidelines of the holding of the Annual General Meeting of the Senegalese swimming federation has revisited all issues related to the proper functioning of the discipline.

California freshman Missy Franklin was named Pac-12 Women’s Swimmer of the Month and USC junior Haley Ishimatsu was named Diver of the Month for the month of the February, the Conference office announced Monday.
Franklin, a Centennial, Colo. native, collected a total of six titles at the 2014 Pac-12 Women’s Swimming and Men’s and Women’s Diving Championships in Federal Way, Wash. Feb. 26-March 1, earning three individual titles in addition to three team relay championships. Franklin set Pac-12 meet records in the 100 freestyle (47.17), 200 freestyle (1:42.29) and 500 freestyle (4:35.73) en route to winning those three events in her Pac-12 Championships debut. As a member of three Bears’ relay teams, Franklin and her counterparts took first in the 800 freestyle, 400 medley, and 400 freestyle relays. With Cal trailing Arizona heading into leg four of the 400 free relay, Franklin swam the anchor and pulled the Bears ahead in the last 50 yards to secure the third relay victory on the week. Franklin earned the most titles of any swimmer at the Championships and was honored as the Women’s Swimmer of the Meet.
Ishimatsu, the defending Pac-12 and NCAA champion on platform, won her first conference springboard title at USC with a 347.25 in a tight battle. She bested Stanford’s Stephanie Phipps (338.50), the winner of the one-meter dive, to mark USC’s 27th Pac-12 diving title and the 12th on 3-meter. Ishimatsu then followed her three-meter performance by becoming the first Pac-12 woman to repeat on platform since Arizona State’s Trish Tumlinson did so in 2004 and 2005. Her 340.20 points, more than 40 better than second place, were a Pac-12 Championships meet record and 5.40 off the Conference record.
This is the second-career Swimmer of the Month honor for Franklin and the 12th overall for California, the most of any Pac-12 school since the award’s inception. Ishimatsu earns her first-career weekly honors and 12th overall diving honors for USC, also the most of any Pac-12 school.
With 135 days to go until the start of the Commonwealth Games, swimmer Michael Jamieson was on hand to formally start the official countdown clock to Glasgow 2014, at the city’s Central Train Station.
The Glasgow-born Jamieson, who won Olympic silver in the 200 metres breaststroke at London 2012, helped to mark the landmark moment along with official Games mascot Clyde and members of Glasgow 2014, including chairman Lord Smith.
The countdown clock, supplied and powered by official Glasgow 2014 timekeeper Longines, will be situated above the destination board at the station, where it will be seen by thousands of commuters and visitors in the lead-up to the Games which are due get underway at Celtic Park on July 23.
“The switching on of the Glasgow 2014 official countdown clock is a reminder that time is ticking towards the Opening Ceremony on 23 July,” said Leader of Glasgow City Council, Councillor Gordon Matheson.
“The excitement has been building for some time now for what will be the greatest Commonwealth Games ever, and anticipation will soon reach fever pitch as we welcome the world to Glasgow.
“Like so many other people, I can’t wait for the Games to start.”
Swiss company Longines has been producing time pieces for more than 130 years and has a long tradition of involvement in official sports timekeeping, most notably with equestrian sports, gymnastics, archery and alpine skiing as well as being the official timekeeper at the French Open in Roland Garros.
“Longines is very proud to be the official timekeeper and official watch of Glasgow 2014,” said the firm’s vice-PresidentCharles Villoz.
“Together with Glasgow 2014, we share common values such as tradition and performance.
“We are happy to bring our timekeeping expertise to the largest multi-sport event ever to be held in Scotland.
“We are looking forward to the thrilling and emotional action-packed moments that we are sure to experience this summer.”
Jamieson, who will be hoping to be one of the big stars at the Tollcross International Swimming Centre this summer, was in the city as part of the Sport your Trainers campaign which helped to mark celebrations recognising today as Commonwealth Day.
Prior to heading to Glasgow Central Train Station, Jamieson and mascot Clyde started the day by visiting Glasgow’s Hillhead Primary School, to encourage youngsters to wear their trainers and show support for the Games.
“It has been great to be here in Glasgow and celebrate Commonwealth Day, Sport Your Trainers and the switch on of the Glasgow 2014 clock,” said 25-year-old Jamieson.
“It just brings home to me how fast the clock is ticking to July.
“Glasgow 2014 is going to be one of the highlights of my career and I’m delighted to be playing a part in the run up to the Games in my home town as an ambassador.
“As well as being an athlete the great thing for me as a sports fan is being able to attend other events and I can’t wait to get to see as much as I can at Glasgow 2014.”
