Researchers found levels of toxic metals in the air were higher in samples taken closer to holidays associated with fireworks – Independence Day and, often, New Years. Pixabay

A new study indicates that fireworks, so common in the United States as the July 4th Independence Day holiday approaches, may be harmful to humans and animals.

The study, conducted by researchers at the New York University (NYU) School of Medicine and published Thursday in the Particle and Fibre Toxicology Journal, indicates that common fireworks displays and other commercially available fireworks that explode in the air release heavy metals such as titanium, copper, strontium and even lead particulates into the air.

The study showed the metals, when breathed into the lungs, can be harmful to humans and other mammals and could cause long-term health problems.

The NYU researchers say that previous studies on firework safety focused on physical injuries that might be suffered as they explode. But the study’s co-author, environmental medicine expert Terry Gordon said they wanted to know whether the toxins released by them posed a significant risk.

Gordon tells the science publication Inverse that their team gathered 12 brands of fireworks commonly sold in the United States and set them off in a sealed chamber and collected the emitted particles. They then exposed human cells and living mice to the particles to test them for toxicity.

They also studied 14 years of air quality samples taken across the United States by the Environmental Protection Agency. They found levels of toxic metals in the air were higher in samples taken closer to holidays associated with fireworks – Independence Day and, often, New Years.

The researchers say they hope the study can be used to find safer materials to use in fireworks. But they also recommend that all home fireworks be set off outside, that people stay upwind from fireworks displays when possible, look for fireworks that do not use a lead and save them for special events.

The world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

Heinz has just rolled out a new product that the condiment company says is the "biggest innovation in sauce since the packet itself." Earlier this month, the world's largest producer of ketchup announced the Packet Roller, a ketchup bottle-shaped gadget that allows users to squeeze the most out of a condiment packet, CNN reported.

"Do not click 'purchase' unless you are prepared to change everything about the way you sauce," the Heinz Packet Roller website says. The roller goes for $5.70. The roller is pocket-sized, can be added to a keychain, and features a packet corner cutter.

Swiss tennis ace Roger Federer, is recovering from a right-knee surgery he underwent last month.

Swiss tennis ace Roger Federer, who is recovering from a right-knee surgery he underwent last month, said on Sunday that it was a difficult process to decide whether to undergo a third right-knee surgery after having two last year. But following Wimbledon, where he was "really unhappy" with his performance in reaching the quarterfinals, Federer opted to go through with it.

Federer, who made a late decision to attend this year's Laver Cup in Boston -- a tournament held between teams from Europe and the rest of the world -- said on the sidelines of the event that the recovery and rehabilitation are "going to take me a few more months and then we'll see how things are at some point next year". "The reception I've received, everybody is so upbeat that I'm here. They wish me all the best and they don't even see the crutches. They just want me to be good again and enjoy the weekend," Federer said in an interview for the event with former world No. 1 Jim Courier.

"I've seen some incredible tennis, some great matches and it's been wonderful. I'm really happy I made the trip," the winner of 20 majors was quoted as saying by atptour.com. On why he opted for a third surgery, the tennis ace said, "I was just nowhere near where I wanted to be to play at the top, top level. But I tried my best and at the end... too much is too much. Now I've just got to take it step by step," Federer said.
