Tag: mercury

Over the weekend, I took my daughter to the Ty Warner Sea Center. Between petting the sharks and holding the hermit crabs, we passed by their exhibit on consuming sustainable fish. As a part of the exhibit, they made available these handy little wallet guides to help make seafood choices when shopping or dining easier. The Monterey Bay Aquarium created the guides and they update them each year. They also have a Sushi Guide which I grabbed too.

Most health professionals will tell you that consuming fish is healthy. What you’ll learn through these guides and other resources  is, that unfortunately, many varieties are overfished or are caught/farmed in ways that harm other marine life or the environment. In addition, health concerns surrounding mercury and PCBs (polychlorinated biphenyls) exposure are very legitimate. Below is a list of resources to help you make the best seafood choices. Want the cliff notes? Skip to the bottom and see the Super Green List of seafood.

Seafood Watch

The Monterey Bay Aquarium has a whole section of their website devoted to helping people find the best seafood options.

Mobile Apps

  • Seafood Watch has helpful smart phone apps for both the iPhone and Android. Best of all? They are free and very easy to use. A quick search on my iPhone does show other seafood apps, but most are not free.

Environmental Defense Fund (EDF)

The EDF supplied the containment information for the Seafood Watch guides. Their site features:

  • A great chart which shows the maximum servings that can be safely eaten each month of a long list of fish (with regards to mecury & PCBs)
  • A complete list of seafood with “Eco-Ratings”
  • A Fish Oil Supplement guide


Eating Well has put together their own Seafood Guide. It is a long list of fish and for each type, shows:

  • Health concerns – mercury, PCBs
  • If it is a good source of Omega-3s
  • Harvest notes – impact on environment/overfishing/farming

The Super Green List

The Monterey Bay Aquarium has identified seafood that is “Super Green,” meaning that it is good for human health and does not harm the oceans. This list highlights options that are currently on the Seafood Watch “Best Choices” list, are low in environmental contaminants (below 216 parts per billion [ppb] mercury and 11 ppb PCBs) and are good sources of long-chain omega-3 fatty acids (at least the daily minimum of 250 milligrams). This list is considered the “best of the best” and was last updated September 2010.

  • Albacore Tuna (troll- or pole-caught, from the U.S. or British Columbia)
  • Freshwater Coho Salmon (farmed in tank systems, from the U.S.)
  • Oysters (farmed)
  • Pacific Sardines (wild-caught)
  • Rainbow Trout (farmed)
  • Salmon (wild-caught, from Alaska)

LEDs for Earth Day

Happy Earth Day!

I’ve become an early adopter of LED light bulbs and won’t buy another CFL for the rest of my life. Here’s why: One day my wife knocked over the table lamp in our bedroom and, unbeknownst to her, broke the bulb. Since she didn’t know, my wife simply picked the lamp back up. It wasn’t until two days later I tried to turn on the light and it was dead. Then I saw the broken bulb, which normally wouldn’t be much of a problem except with was a CFL which contain mercury, so now my wife and I were sleeping for two nights in a room with particles of mercury. Did we get sick? No, but just the feeling of mercury in the air never sat right with me. Thankfully LED bulbs have come to the rescue and offer so many benefits:

  • Efficiency – Far more efficient than CFLs
  • Insane Longevity – you get 25,000 – 50,000 hours from one bulb. That will last you over 10 years at 6 hours a day!
  • Durability – you can drop them onto a concrete floor and they won’t break since there’s no glass
  • Safety – there is no mercury in them

So, what’s the catch? Well, they are expensive but prices are dropping fast. I bought 2 last year at $37 a piece, and just today I found EarthLED has an Earth Day sale on their Zetalux 2 LED bulbs today only for $9.89 a piece. I bought 8 of them. Keep in mind they are 40 watt replacements so they won’t be quite as bright as a 60 watt bulb. As you replace your bulbs for your home and kitchen, consider using LEDs instead of CFLs as a more earth-friendly option.
