Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983

HARTSHORNE, Okla. – A veteran says he is being kicked out of his home by the City of Hartshorne.William Smith has called a camper home for the last eight years on property that he owns. Now, Hartshorne is telling him to pack it all up and find somewhere else to live.William Smith said, "The hookups were here: water, sewer, and electric. Everything was here. I just figured since I had already been living in my RV and it was mine and it was paid for and I got my property paid for, I thought I was good to go for many, many years."Smith was a Navy radar engineer, constantly moving around."To get all of my equipment on an airplane was not a thing that you could really do," he said.He tinkers in his garage on the property, which is the main reason he bought the land, and generally keeps to himself. So, the veteran was surprised when he the police handed him an eviction notice.It said he had 120 days to relocate. Due to a new ordinance passed by the city council, recreational vehicles, travel trailers and campers no longer specify as a structure for permanent living in the city limits. The city claims the reason is "preservation of the public peace, health, and safety.""They told me there's no provision for a grandfather clause or anything that would allow me to stay here," Smith said,Although some may be concerned about property value, most of Smith's neighbors say they would rather see a camper with a well-kept yard next door to them than an abandoned house like several on Smith’s street.Now, the retired veteran is left in limbo, trying to figure out his next move in life."I bought the place so I could retire here and work in my garage to do my piddling and my projects and all that. So, if I have to move this thing out, I really have no other home," he said.Mayor Joy Cline told a local newspaper the city would work with the elderly and disabled and would not leave anyone homeless under this new ordinance. However, she did not respond to a request for comment. 2016

FULLERTON, Calif. (AP) — Police say a suspect has been arrested in the stabbing death of a man at the California State University, Fullerton campus.Fullerton police Lt. Jon Radus on Thursday told The Associated Press that 51-year-old Chuyen Vo was arrested Wednesday night at his home in Huntington Beach. Vo is suspected in the death of a former co-worker, 57-year-old Steven Shek Keung Chan. Police would not elaborate on the work relationship between the two men.Chan worked as the director of budget and finance and student services for university extended education but retired in 2017. He returned to the campus in January to work as a consultant.Authorities have said Chan was found stabbed numerous times inside his silver Infiniti in a campus parking lot on Monday, and they believe it was a targeted attack. 825
