Details

Peracetic acid (PAA) is an extremely strong oxidizer widely used in the food industry for disinfection of piping systems and processing equipment.  It is also used for spray washing of food products, and for disinfection of cooling water systems.  As a disinfecting agent, PAA is often preferred because it produces no harmful breakdown products.  

As with any disinfection system, maintaining proper residual values is the key to effective pathogen control.  To facilitate reliable chemical feed control, ATI has developed an on-line monitor cable of providing real time measurement of low levels of PAA in solution.  The Q46/85 Peracetic Acid Monitor uses a direct sensing polarographic probe.  The probe is typically used in a flowcell, but a submersible sensor is also available.  A permeable diffusion membrane isolates the sensing electrodes from the measured sample, providing long-term stability without electrode fouling problems. The measurement is selective for PAA and is not affected by changes in hydrogen peroxide concentration, which is always present in PAA solutions.

Peracetic acid sensors are amperometric devices isolated from the water by a permeable membrane.  As PAA diffuses through this membrane, it comes in contact with an active electrode and is reduced on the surface.  The net effect is that the sensor generates a current proportional to PAA concentration.  An integral RTD in the sensor provides for automatic temperature compensation, allowing the sensor to operate accurately over a range of 0-50° C.
 
Peracetic acid sensors are capable of operating over a fairly broad concentration range, from a low range of 0-20 PPM up to a high range of 0-2000 PPM.  Systems will operate with good sensitivity down to 0.2 PPM and respond to changes in concentration within about 60 seconds, making them useful for automatic control.

Peracetic Acid sensors require a steady flow of sample across the membrane at the tip of the sensing assembly.  ATI offers options for flowcells, including the standard constant-head overflow system, and a sealed flowcell for pressures up to 50 PSI. For simplicity of installation, complete flow control assemblies are available. Panel assemblies are available with or without a flow switch and can greatly reduce installation time. For open tank installation, a submersible sensor is available. Sample agitation is required as PAA sensors cannot be used in still water.

Rising Atmospheric CO2 Levels Affecting Cephalopod Behaviors

Carbon dioxide, CO2, is a waste product for animals, including humans. That means that too much of it can be dangerous. In humans, excessive exposure to CO2 can kill, but in lesser amounts it can also affect the blood's pH level, causing acidemia. Acidemia can cause nerve damage , including hallucinations, delirium, and seizures. Far less is known about the subtler effects of CO2 on cephalopods, but this is in large part because far less is known about cephalopods, generally. However, new research from scientists at James Cook University (JCU) in Australia reveals that rising levels of atmospheric CO2 may cause strange behavioral effects in cephalopods—effects that are likely to be dangerous to them.

Buoy Data Powers Muskegon Lake Hypoxia Research

Sixty years ago, the famous ecologist George Evelyn Hutchinson wrote, “A skillful limnologist can possibly learn more about the nature of a lake from a series of oxygen determinations than from any other chemical data.†Since then, oxygen measurements have only grown more relevant as the problem of hypoxia expands in lakes, oceans and estuaries across the globe.   But ecologists’ ability to measure oxygen has grown too. When Hutchison wrote that in 1957,  the “series of oxygen determinations†produced by a data buoy like the one floating on Muskegon Lake in Michigan was unthinkable.

Long-Term Monitoring Aids Scientists Studying Sea Star Wasting Mystery

Scientists working to solve the mystery of Sea Star Wasting Disease—and to learn more about the possible keystone species Pisaster ochraceus , the ochre sea star—are reaping the benefits of long-term monitoring of the species along the West Coast. Dr. Melissa Miner , a UC Santa Cruz researcher in the Department of Ecology and Evolutionary Biology, spoke with EM about her two decades of work with the Multi-Agency Rocky Intertidal Network and her recent efforts surrounding the ochre sea star. Keeping an eye on intertidal species In 2013, people began to notice that sea stars all along the West Coast were in the grip of a strange disease. The stars exhibited lesions and quickly succumbed, deteriorating and wasting away.
