Details

The Extech Noise Dosimeter Data Logger is designed to measure total sound exposure over an 8-hour period of time. It is also popular for performing OSHA and IEC noise accumulation surveys as well as more simple applications like personal or workplace accumulated noise exposure tests. The unit allows for several adjustments based on the application, such as the criterion level, exchange rate, and threshold. Before and after using this dosimeter, it's recommended to perform calibration checks with either the 407744 or 407766 sound level calibrators.

The meter can log up to 4500dB readings when used as a sound level meter. As a dosimeter, it can store up to 5 surveys. These surveys would include start/stop time, %dose, TWA, and peak flags. For connection to a PC, simply use either the RS-232 cable or optional USB cable. The software is perfect for controlling setup and retrieving stored events or analyzing real-time measurements.

Seeking an Elegant, Affordable Solution to Contamination

Dr. Charley Liberko of Cornell College's Department of Chemistry has an idea he's working to bring to fruition. “Imagine a remote village in an underdeveloped country whose only source of water is a stream contaminated with toxic levels of metal ions such as cadmium and nickel,” states Dr. Liberko. “The villagers take locally available woody plant material, soak it in potash, and heat it up for several days until the wood partially decomposes. They then filter their water through this material to remove the metal ions. When they are done with it, they put the material in a clay pot and heat it up even hotter until the organic matter decomposes completely, leaving the metal ion salts as a residue, safely in the clay pot.

New Fish Lab Offers Unique Opportunities

Sometimes scientists have to make an extraordinary effort to study the questions that concern them. In fact, they may even need to design and build labs to their specifications. This was the case with the University of Nebraska, Lincoln's (UNL’s) Fish Conservation Behavior and Physiology Lab , which serves as a locus for research on water management best practices based on fish physiology—work conducted by up and coming scientists as well as more established researchers. Dr. Jamilynn Poletto spoke to EM about how the lab was built and the work that is happening there. Building a customized solution “My problem was that in the lab we get city water from Lincoln, and any water from any city in the country has chlorine and chloramine in it,” explains Dr.

From Acid Rain to Cyanobacteria, Cary Institute of Ecosystem Studies is a Leader in Environmental Monitoring

Cary Institute of Ecosystem Studies , an independent environmental research organization in Millbrook, NY, is a leader in environmental monitoring – particularly long-term monitoring that spans decades. Steve Hamilton is a freshwater ecologist at Cary Institute and professor at Kellogg Biological Station , a member of the Organization of Biological Field Stations ( OBFS ), at Michigan State University. Hamilton explains, “Environmental monitoring is how ecologists keep a finger on the planet’s rapidly-shifting pulse. By tracking ecological indicators over long timescales, we can identify patterns and better understand how ecosystems are changing. This understanding will guide us as we work to adapt to and mitigate environmental degradation.
