ALL4’s: Is That Your Final Answer?

Posted: April 30th, 2012

Author: All4 Staff 

Last Month’s Answer and Winner:

There were many, many respondents who correctly identified the location of the terrible smog event in 1948 as Donora, Pennsylvania; however, Mike Huncik was the first and thus is the March “Is That Your Final Answer” winner.  Sometimes as we are stumbling through and puzzling over the most recent U.S. EPA rulemaking, it is probably a good idea to reflect back and consider the progress that we have made improving the environment over the past sixty plus years.


And progress is the key to our April “Is That Your Final Answer” question.  Over the past thirty years we have seen all sorts of improvements to how environmental measurements are made.  Whether the measurements are made to analyze pollutant concentration levels in a stack or to determine real-time ambient air fine particulate levels, we can now make better, faster, and more accurate environmental measurements.  So this month we will challenge you with the following picture of a measurement device that is now often replacing a robust and reliable measurement device.  Name this piece of equipment pictured to the right and tell us what it measures before anyone else and you will be the April “Is That Your Final Answer” winner.  Good luck!


Please e-mail your answer to final.answer@all4inc.com.  Include in the e-mail your name, answer, and address (to receive your prize).

ALL4’s Final Answer is a monthly feature of our Blog Digest.  It is designed to test your knowledge across the environmental field, quiz you on the building blocks of air quality rules, stump you on ALL4 general trivia, and challenge you with brain teasers that have perplexed us.  The first correct answer e-mailed to us will qualify the respondent for free ALL4 gear and will enter the winner in our end-of-the year “Final Answer Championship.”  The subsequent month’s Final Answer will identify the winner and the correct answer from the previous month’s question.  You must be an active subscriber of ALL4’s Blog Digest to win a monthly prize and be eligible for the championship prize.  ALL4 employees and family members are not eligible to compete.  Hope you enjoy this feature and good luck!
