Study Spoiling 4th Of July Fun Says Fireworks Release Harmful Particulates Into The Air

By
Just in time for the Fourth of July comes some news that might put a damper on your celebrations: A new study says exploding fireworks create toxic air pollution that could be harmful to your health. Happy Independence Day, everyone.

A study by federal scientists from the National Oceanic and Atmospheric Administration published in the journal Atmospheric Environment says the thousands of Fourth of July firework celebrations we set off around the country is contributing to air pollution, releasing tiny particles called particulates into the atmosphere.

Those particulates can affect your health because they travel into your respiratory tract and enter the lungs. Other particulate matter includes dust, dirt, soot smoke and liquid droplets, notes USA Today. They’re measured in micrometers, which is one-millionth of a meter.

In this study, particulates from fireworks were 2.5 micrometers in size. Whether you’re breathing them in often or only in the short-term, the particulates are linked to health effects like coughing, wheezing, shortness of breath, asthma attacks and even heart attack and stroke. It could contribute to premature death in people with heart or lung disease, the study says.

When it comes to the Fourth of July, the air will be at its most particulate-laden between 9 and 10 p.m. — which makes sense as that’s when it gets dark in the summer and many cities around the nation shoot off their fireworks. By noon on July 5, levels drop back down.

“These results will help improve air quality predictions, which currently don’t account for fireworks as a source of air pollution,” said Dian Seidel, NOAA scientist and study lead author. “The study is also another wake up call for those who may be particularly sensitive to the effects of fine particulate matter.”

Chrysler Deletes Its Dating Apps, Decides To Remain Single For Now

By
They say you can’t have a healthy relationship until you’re happy with yourself. That appears to be the new mantra for Fiat Chrysler: After several attempts to woo General Motors and more recently Volkswagen , the carmaker’s top executive says he plans to ditch his lovelorn ways to concentrate on his company’s bottom line.  Bloomberg reports that CEO Sergio Marchionne has turned his focus to eliminating FCA’s debt rather than eliminating its single status. Marchionne has set a goal of erasing FCA’s debt by 2019, the same year he’s set to retire. To do that, he says the company needs to do a little work on itself. “We need to be very careful that we don’t start unrealistic dreams about consolidation as we are on our way to achieve historically important results and a debt-free position,” Marchionne told investors at the carmaker’s annual meeting in Amsterdam, as reported by Bloomberg. “We are not at a point of time to discuss any alliance.” Yes, you heard that right: The man w...

Study Claims 43% Of “Wild” Salmon In Stores & Restaurants Isn’t Wild At All

By
That wild salmon entrée calling to you from the menu at dinner might not be all it’s advertised. In fact a new study released Wednesday found evidence of mislabeling in nearly half of all salmon sold in restaurants and grocery stores.  The study [ PDF ] from international environmental advocacy group, Oceana, analyzed 82 salmon samples from restaurants and grocery stores, finding that 43% of the products were mislabeled. DNA testing confirmed that 69% of the mislabeled product consisted of farmed Atlantic salmon being sold as wild-caught product. According to the report, consumers satisfying their salmon craving in restaurants are misled about 67% of the time, while those who buy their seafood in a grocery store are misled 20% of the time. “Americans might love salmon, but as our study reveals, they may be falling victim to a bait and switch,” Beth Lowell, senior campaign director at Oceana, said . “When consumers opt for wild-caught U.S. salmon, they don’t expect to get a far...

Introduction to Biology (IX Biology Notes Chapter 01)

By
Science: Our universe operates under certain principles. For understanding of these principles, the experiments are done and observations are made; on the basis of which logical conclusions are drawn. Such a study is called "Science". In brief science is the knowledge based on experiments and observations. Biology: The Scientific study of living organisms is called Biology. The word biology is derived from two Greek words "bios" meaning life and "logos" meaning thought, discourse, reasoning or study. It means that all aspects of life and every type of living organism are discussed in biology. Branches of Biology: Biology is divided into following branches: Morphology The study of form and structure of living organisms is called morphology. It can be further divided into following two parts: 1. The study of external parts of living organism is called external morphology. 2. The study of internal parts of living organism is calle...
