Katie Chin | Daily TrojanFlying high · Redshirt sophomore Marquís Morris was one of many USC student-athletes and graduates competing at last week’s USATF Championships in Sacramento, Calif. Morris was a semifinalist in the 110m hurdles, while Trojan alumnus Aleec Harris triumphed in the finals to claim the national title.The USC track program shone at the USA Outdoor Track and Field Championships last week, with both alumni and collegiate stars impressing during the four-day competition in Sacramento, Calif. Former Trojans Dalilah Muhammad and Aleec Harris earned titles in the 400m hurdles and 110m hurdles, respectively, and current Trojans smashed multiple team records.At the meet, five USC runners — four graduates and junior Kendall Ellis — qualified to represent the United States at the IAAF World Championships in August. Ellis will team up with Trojan track greats Muhammad, Harris, Allyson Felix and Nia Ali as they gun for glory in London. Ellis and Felix will both run the 400m, Harris will enter the 110m hurdles and Muhammad will compete in the 400m hurdles.Muhammad earned her second career USA title in the women’s 400m hurdles on the last day of action at Hornet Stadium. The 2016 Olympic gold medalist recorded a personal-best time of 52.64 to win the finals, while Harris topped the men’s 110m hurdles with a time of 13.24.For the current Trojans, Anna Cockrell competed in the women’s 400m hurdles finals and finished eighth overall (55.14), breaking her USC freshman record in the process. Junior Deanna Hill recorded a time of 23.04 to come in sixth in the women’s 200m finals.Numerous USC athletes also starred in the competition’s earlier days. Ellis broke her own all-time school record in the 400m on Friday and repeated the feat Saturday. She trimmed her first time of 50.24 down to 50.00 flat to take third overall and earn a spot on the USA roster. Michael Norman bettered his USC freshman record in the 400m on Saturday, running to finals qualification in 44.60 seconds. The time also elevated Norman to third place on the program’s all-time 400m list.Senior Cameron Pettigrew qualified for the 400m semifinals with a time of 51.74, and junior Ricky Morgan Jr. also advanced on the men’s side after recording a time of 45.47 — just .03 seconds from his personal best.Redshirt sophomore Marquís Morris ran in Harris’ heat in the first round of the 110m hurdles, and he qualified for the semifinals with a 13.73 mark while Harris won the heat. Morris did not advance to the finals, however, settling for 14th overall.After the end of the USATF Championships, Trojan athletes will look forward to rooting on Cockrell at the biennial World Championships, which features more than 200 countries. The United States is the winningest nation in the competition’s history.The IAAF World Championships kick off on Aug. 4 at London Stadium.
Aug 14 2018Babies in prams can be exposed to up to 60 percent more pollution than their parents, causing potential damage to their frontal lobe and impacting on their cognitive abilities and brain development.In a study published by the Global Centre for Clean Air Research (GCARE) at the University of Surrey in Environment International, researchers examined more than 160 references to highlight the factors concerning the pollution exposure of babies in prams and associated mitigation strategies.GCARE researchers also investigated different types of prams based on their height, width, and whether they seat one child or two to assess if this impacted on pollution exposure levels. They found that infants in prams breathe in more polluted air since they are positioned between 0.55m and 0.85m above ground level and vehicle exhaust pipes usually sit within 1m above road level. This increases in-pram babies’ vulnerability to being exposed to more pollution than adults.The study suggests a range of mitigation actions, including ‘active’ solutions such as controlling emissions of road vehicles, and ‘passive’ actions, such as roadside hedges between vehicles and pedestrians. The researchers also suggested technological solutions that can help to create a clean air zone around the child’s breathing area as another effective mean. They concluded that a mixture of innovative technological solutions, community activism, and exposure-centric policies that encourage authorities to tackle traffic congestion are needed as they are seen to be the key to a lasting solution to the problem.The review also notes other measures such as carpooling, using public transportation to reduce traffic levels, improving technologies and community collaborations with industry could make a real difference to improving air quality for children.Related StoriesInhaling irritant that mimics air pollution changes defensive heart-lung reflex for hypertensionPM2.5 exposure before and after birth associated with reduction in fundamental cognitive abilitiesResearch finds link between air pollution and coronary heart disease in ChinaAccording to UNICEF, 17 million children across the world who are less than a year old live in regions where air pollution levels exceed World Health Organisation recommended guidelines. Children from poor economic backgrounds are most at risk of these dangerous levels of pollution because of a lack of nutrition, access to health care, and exposure to tobacco smoke.Professor Prashant Kumar, who is a Chair in Air Quality and Health and the Founding Director of the Global Centre for Clean Air Research, said: “We know that infants breathe in higher amounts of airborne particles relative to their lung size and body weight compared to adults. What we have proven here is that the height most children travel at while in a pram doubles the likelihood of negative impacts from air pollution when compared to an adult. When you also consider how vulnerable they are because of their tissues, immune systems, and brain development at this early stage of their life, it is extremely worrying that they are being exposed to these dangerous levels of pollution.”Our past research motivated us to set-up the MAPE (Mitigation of Air Pollution Exposure to young children) project that aims to develop targeted mitigation strategies and solutions. We are working together with industrial partners to develop innovative technological solutions and giving this aspect a special attention in our on-going living lab activities, including community and stakeholders’ engagement, part of our another in-progress project, iSCAPE.”With the multitude of evidence we set out in this review, it is important that everyone across the country begin a full and frank conversation about pollution and the impact it has on our most vulnerable – from parents and community leaders, to government officials and industry.” Source: https://www.surrey.ac.uk
