Webinar – Analysis of Environmental Contaminants in Water Using an Agilent 6470 LC/TQ Instrument

Mark your calendar guys for Wednesday April 12th 2017  at 3.00 PM for the above mentioned Webinar on the new 6470 LC/TQ from Agilent Technologies which would be used for the detection of several pharmaceuticals and pesticides in surface waters.

For decades now, the most common detected environmental contaminants in water are pesticides and pharmaceuticals. Because these types of organic compounds are mostly polar, liquid chromatography mass spectrometry has been the methodology of choice for their analysis. Usually a sample preparation step such as solid-phase extraction has been necessary for the detection of these contaminants at low ng/L. However, with the advent of newer and more sensitive instruments, this step can be omitted while still achieving these low detection limits. In this session we’ll show some examples of compounds identified in surface waters at these concentration levels and how to optimize the best conditions and parameters for their optimal detection.

In this session, we’ll focus on the use of the new 6470 LC/TQ instrument from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source parameters and voltages will be shown for the ionization of specific analytes, including hormones. Also, quantitation using larger volume injections (100uL) will be shown for the direct analysis of contaminated water samples.

What you will learn:

  • How to optimize intrinsic source parameters in MassHunter software
  • Large volume injection (100uL) considerations
  • Learn to choose best product ions with Optimizer software
  • Method development techniques
  • A list of the most commonly detected pharmaceuticals in surface and drinking waters

Global Significance of the Changing Freshwater Carbon Cycle – EOS

By Bopaiah A. Biddanda

Freshwater ecosystems constitute a small fraction of our planet but play a disproportionately large and critical role in the global carbon cycle.

As human activities continue to pump carbon into the atmosphere, the backbone of our understanding of the resulting warming is our knowledge of where that carbon is going: into the atmosphere, into the land, and into bodies of water. When it comes to accounting for the carbon absorbed and emitted by water, the role of inland freshwater may appear quite small compared to the vastness of Earth’s oceans. After all, inland lakes, rivers, streams, reservoirs, wetlands, and estuaries cover less than 4% of Earth’s surface [Downing, 2010; Verpoorter et al., 2014].But recent research shows that the roughly 200 million bodies of inland water play a much larger role in the global carbon cycle than their small footprint suggests. Inland streams and rivers move vast amounts of carbon from the land to the ocean, acting as carbon’s busy transit system.

They also play a disproportionately large role in the global carbon cycle through their high rates of carbon respiration and sequestration [Cole et al., 2007; Tranvik et al., 2009].According to recent estimates, the amount of carbon that inland waters emit is comparable to the net amount of carbon absorbed by living organisms on Earth’s land surface and in its oceans. Moreover, bodies of freshwater bury more carbon in sediments each year than the vast ocean floor [Battin et al., 2009; Aufdenkampe et al., 2011].

Nevertheless, there is great uncertainty in these figures, and scant data exist on continental and global scales. The changing climate is putting freshwater ecosystems at great risk: They are warming at an alarming rate, outpacing warming of the atmosphere and oceans. It’s crucial that scientists dedicate more resources to understanding the global impact of the freshwater continuum on the carbon cycle.

Mapping the Topographic Fingerprints of Humanity Across Earth – EOS

By , Giulia Sofia, and Erle Ellis

If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface

Since geologic time began, Earth’s surface has been evolving through natural processes of tectonic uplift, volcanism, erosion, and the movement of sediment. Now a new force of global change is altering Earth’s surface and morphology in unprecedented ways: humanity.

Human activities are leaving their fingerprints across Earth (Figure 1), driven by increasing populations, technological capacities, and societal demands [e.g., Ellis, 2015; Brown et al., 2017; Waters et al., 2016]. We have altered flood patterns, created barriers to runoff and erosion, funneled sedimentation into specific areas, flattened mountains, piled hills, dredged land from the sea, and even triggered seismic activity [Tarolli and Sofia, 2016]. These and other changes can pose broad threats to the sustainability of human societies and environments.

If increasingly globalized societies are to make better land management decisions, the geosciences must globally evaluate how humans are reshaping Earth’s surface. A comprehensive mapping of human topographic signatures on a planet-wide scale is required if we are to understand, model, and forecast the geological hazards of the future.

Understanding and addressing the causes and consequences of anthropogenic landform modifications are a worldwide challenge. But this challenge also poses an opportunity to better manage environmental resources and protect environmental values [DeFries et al., 2012].

Cost-Saving Strategies for Water Utilities – Forester Network

Please note that the article Cost-Saving Strategies for Water Utilities – Forester Network was written by Carol Brzozowski for March 10, 2017.

Water utility operators face many financial hardships these days. Today, cash-strapped utilities are challenged to deliver optimal levels of service while saving money on water treatment costs.

Treatment costs are not isolated and must be considered as part of the overall cost of water service, points out Brian Bokowy, business manager CIM for AllChem Performance Products. “Water utilities—particularly utilities that have multiple locations and multiple well sites, booster stations, and multiple treatment areas—have all of the logistics of transportation, storage, handling, and safety concerns of securing all of those individual sites,” notes Bokowy.

Oftentimes, safety concerns will dictate more than one employee going out to a site whenever chemicals are being handled, he adds. “All of these additional visits out to sites, all of the additional safety and handling concerns, add real costs to chlorinate that water for the municipality,” says Bokowy.

“By moving to safer, less hazardous chemicals, it reduces costs by eliminating some of the storage concerns, and eliminating some of the extra personnel and trips out to the sites that may be involved with the manhours associated with going out to those sites.”

AllChem Performance Products specializes in chlorination equipment, especially tablet feed systems. The systems are designed as an effective way to chlorinate drinking water and wastewater without the costly safety and hazard concerns associated with handling, transporting, and treating with gas chlorine or liquid chlorine sodium hypochlorite, notes Bokowy.

One system offered by the company is the PTF-100 Feed System, consist­ing of the Horizon PTF-100 Tablet Feeder and Horizon 90 PT Tablets.
