Toxic Algae

first_imgThe sudden and unexpected death of a Marietta, Georgia, couple’s beloved dog after swimming with its owners in Lake Allatoona has filled social media feeds since the incident on Aug. 10. The incident brings to light the dangers of toxic algae growth. In neighboring North Carolina, another couple lost three dogs in one day after an afternoon swim in a pond.The cause has been identified as the blue-green algae species Microcystis aeruginosa, a cyanobacteria that produces a potent liver toxin.Algae often grows in ponds and lakes during abnormally dry conditions such as those Georgia is currently experiencing. Toxin-producing algae can be lethal to livestock who use farm ponds as their water source, but common toxins like microcystins can also impact larger bodies of water, said Gary Burtle, University of Georgia water quality and fisheries expert.While Georgia isn’t officially in a drought, areas of the state have been hotter and drier than normal, Burtle said.Conditions like these can cause more algae to grow and bloom in bodies of water as a result of the increased nutrient load in ponds and lakes, he said. In ponds used to water cattle and horses, this might lead to problems with toxic algae and unsightly water.Color changes in a pond can be a clue that algae are blooming. Blooms of algae and cyanobacteria often look like green, blue-green or reddish-brown paint floating on the surface of small bodies of water, usually near the shoreline. This scum formed by algae is an indicator that the pond may be unsafe, Burtle said.“Humans should not swim in this water and animals should not be allowed access to it until the bloom returns to normal by dilution from rainfall or treatment with algaecide,” said Burtle, who has fielded numerous calls from UGA Cooperative Extension agents this week as questions have poured in from the public. “You know a pond is headed for trouble when the algae bloom is so thick that visibility is less than 12 inches into the water column.”In 2012, Georgia experienced serious drought conditions and some Gwinnett County cattle died as a result of a cyanobacteria bloom. Animals affected often appear weak, exhibit muscle tremors and convulsions, and have bloody diarrhea.Farm animals should be kept away from the water source and provided with an alternative source of clean water until the pond has been tested and is declared free of toxins, Burtle said.“If you have a fear about the water, move your animals to a safe water source,” Burtle said. “Install a water tank and fill it up every day or so. And use common sense. If there’s a scum on the pond and you think there might be a problem, exclude your animals and have the water tested.”UGA Extension agents can help Georgians test their pond or lake water for the presence of toxins from algae blooms through UGA College of Agricultural and Environmental Sciences laboratories.Cyanobacteria blooms in ponds and lakes are difficult to control, Burtle said. Using chemicals releases more toxins into the pond, rendering it useless as a water source for weeks or months. High daytime temperatures can also force the cyanobacteria blooms to the bottom of the pond, where toxins are released.Harmful algal blooms need nutrients, sunlight, and warm, stagnant water to develop.To help prevent blooms, UGA Extension urges pond owners to leave vegetated buffers around ponds, to limit livestock access and to avoid over-fertilizing surrounding areas. Pond owners who would like to learn more about controlling algae should read UGA Extension Bulletin 1445, “Managing Algal Blooms and the Potential for Algal Toxins in Pond Water.”last_img read more

Wilshere hits back at critics

first_img Photos of the midfielder holding a shisha pipe at a nightclub were posted on social media and quickly made national headlines. On Thursday evening, Wilshere posted on Instagram a video of himself in training as he recovers from ankle surgery along with the message : “Worry about your character not your reputation, because your character is who you are and your reputation is only what people who don’t know you think about you!” Press Association The Gunners are to seek clarification from Wilshere over the circumstances of the incident, which is understood to have happened during a night out with friends in central London last week. A picture of Wilshere was uploaded to Instagram, before being removed and replaced with an edited version where only the face of the Arsenal player was visible in the background. However, the original image, where the England international held the shisha pipe, was then subsequently reposted on Twitter, sparking much debate across social media over the player’s behaviour ahead of Saturday’s north London derby at Tottenham Arsenal take a dim view on players smoking. In January, goalkeeper Wojciech Szczesny was hit with a £25,000 fine after it emerged he lit up in the showers following the 2-0 defeat at Southampton on New Year’s Day, since when the Pole has not started a Barclays Premier League match. Wilshere’s representatives said they had nothing further to add when contacted by the Press Association on Thursday. The latest revelations around Wilshere – the midfielder has been criticised in the past after twice being pictured with a cigarette, the previous occasion while on holiday in Las Vegas last summer with England goalkeeper Joe Hart following the 2014 World Cup – will come as an unwelcome distraction to Wenger as he prepares his squad for Saturday’s lunchtime kick off at White Hart Lane, with the subject now set to dominate the agenda at Friday’s morning media conference. Leading scorer Alexis Sanchez will again be out because of a hamstring injury which saw him miss the 5-0 win over Aston Villa, but England forward Danny Welbeck is in line to make a return after being out since December 28 with a thigh problem. Jack Wilshere appeared to hit back at his critics after becoming embroiled in another smoking controversy. Wenger said on the Arsenal club website: “Alexis is not ready. He is not far away, the Leicester game is a possibility. He is of course very difficult to keep quiet. He is training, but it’s light training.” Wenger added Wilshere was set to be “back in full training next week, hopefully from Sunday”. England forward Theo Walcott, meanwhile, is relishing the prospect of the derby atmosphere as Arsenal look to keep the pressure up on the top four. Walcott has just returned to full fitness after the best part of a year on the sidelines when suffering a serious knee injury in the closing minutes of the FA Cup third-round win over Spurs at the Emirates Stadium in January 2014. The 25-year-old was carried off on a stretcher in front of the away supporters, some of whom threw objects to which the player responded with a 2-0 hand gesture. Walcott, whose injury shattered his World Cup dreams, thrives on the rivalry. “This is a massive game and it is all about the bragging rights,” Walcott said in the London Evening Standard. “Things like that have happened in the past and it won’t be forgotten about, I am sure, but it is one thing I have moved on from. “Every player will get stick I am sure, but it is about just trying to go out there and perform.” Walcott, who has scored in successive appearances since his return from a niggling groin problem, added: “Any criticism won’t affect me at all. It is enjoyable – it is a bit different and is always a great atmosphere at White Hart Lane. “It is probably the fixture I always look forward to playing in the most, to be fair. “It is one of the biggest games for both sets of fans and this year it is going to be tight.” last_img read more
