For thousands of years, tea has been one of the most popular drinks around the world. Not only is tea delicious, it is also full of health benefits. Tea is an abundant source of antioxidants called polyphenols. One of these polyphenolic compounds, catechins, are found mostly in green tea. Catechins have been studied thoroughly and have been found to reduce free radical stress, they have also been found to be anti-inflammatory as well as potentially therapeutic for cancer cells.
New year – fresh start
If you’re like me, you start the new year off with a list of resolutions for the coming months – resolutions to be more fit or to secure a promotion at work or to reduce your carbon footprint. Whether you’re trying to improve your health or further your career, these are the types of goals that I like to refer to as getting “back to basics” because they require you to start with a solid foundation which you can build on to achieve success.
It’s one of my favorite times of the year – that time between Christmas and New Year’s Even when you can reflect back on the year to prepare for celebrating the start of a new one.
Happy Tuesday and Merry Christmas to those who celebrate this holiday! If you’re anything like me, you started singing Christmas carols and getting out your lights the day after Halloween. And if you’re like me, you view Thanksgiving as the “halfway to Christmas” holiday. These days, it seems like Christmas gets recognized for nearly 3 months out of the year, but I enjoy every minute of it. To me, it’s a wonderful time of the year – the holly, ornaments, carols, cookies, wreaths, lights and garlands – I can’t get enough.
How familiar are you with naphthalene?
If you have ever used mothballs for storing clothing, you are pretty familiar with a compound known as naphthalene. If you are asking questions like “how would I know if I’ve used mothballs?” or “remind me, what do mothballs look like?” then you’ve never spent any significant time around them. If you had, you would vividly remember the smell that hits you like a brick and brings you to your knees.
Just a reminder of last week’s question:
EPA Method 525.3 is a revision of Method 525.2 which incorporates a number of changes to improve the extraction and quantification of drinking water contaminants. Continue reading Tuesday Trivia – Answer for December 11, 2018
Since oceans cover roughly two thirds of the Earth, and since oceans can demonstrate signs of ecosystem health and climate change, the U.S. EPA has watched the ocean for changes in their physical property for many years. From sea level height to ocean temperature to coastal flooding occurrences to surface temperature, the EPA has closely monitored changes in these properties as an indicator of climate change.
Happy Tuesday! The final question for 2018 focuses on the EPA 500 Series methods that have been developed to quantify organic contaminants in drinking water. For those unfamiliar, EPA Method 525.2 outlines the extraction and quantification of organic compounds in drinking water. The EPA eventually revised the method and released Method 525.3. The updated revision incorporates a number of changes to improve the extraction and quantification of drinking water contaminants. Continue reading Tuesday Trivia – December 11, 2018
“The Earth is what we all have in common.”
If you are like me, you spent yesterday honoring World Soil Day with a variety of research and community activities to acknowledge the importance of this valuable resource. If you live in a colder climate area and the ground is starting to freeze, perhaps your activities were more indoor-focused. That’s OK too.
When you give it some thought, soil is quite an impressive material. In its most simplistic definition, soil is just the Earth’s outer most layer. However, if you dig a little deeper (no pun intended!), soil is the layer of Earth that we depend on in every aspect of our lives.
Soil is what we use to grow our trees and plants which provide us with food to eat and clean air to breathe. It provides us with a stable surface to build our homes and roads. It also stores water and nutrients, provides a nutritious and sustainable environment for billions of organisms, and has the ability to filter toxic contaminants from our surrounding environment. In other words, soil is one of our most precious resources.
“The biggest threat to soil is ignorance and indifference.”
Unfortunately, soil has a finite capacity for retaining contaminants, and decades of industrial pollution, farming activities and improper urban waste disposal have saturated and exceeded the filtering ability of this resource in many parts of the world. Compounding this issue is the fact that soil pollution is a hidden danger. People cannot see the direct impact of their contributions, causing many of them to become oblivious to the magnitude and prevalence of this problem.
As the Earth’s population continues to grow – projections indicate our population numbers will reach almost 10 billion by 2050 – people need to be more diligent than ever in protecting our life-sustaining resources. We keep this thought at the forefront of the solutions we provide, so World Soil Day is a great reminder and opportunity for us to continue developing solutions to monitor and protect our soil for generations to come. After all, healthy (contaminant-free) soil could make the difference between a healthy, thriving ecosystem and a starving, barren wasteland.
