More about metals testing and this webinar

The words, heavy metals, usually fill us with a sense of dread but what are they, how do they affect us, and how do we monitor their levels in our environment?

Our modern lifestyle happens to contribute to a number of environmental concerns. From deforestation to plastic pollution, we are continually looking to find ways to minimise the impact of our actions. Another concern that is also on the rise is heavy metals pollution in our soil and water.

Heavy metals pollution in the environment

Upsurge in processes and electronic waste in our landfills have led to an increase in dangerous metals leaching into the environment. As heavy metals  are not biotransformed, they accumulate and build up in our surroundings. Once in our soil and water, heavy metals can upset the ecosystem and enter into our food chain, leading to many severe and chronic health problems.

Regulations and requirements in metals testing

Any process that affects human health tends to be heavily regulated  and metals contamination is no exception. In Europe, International Organization for Standardization (ISO) regulations are used to monitor heavy metals detection techniques and levels; similarly, there are the U.S. Food & Drug Administration (FDA) and United States Environmental Protection Agency (EPA) mandated processes to control and manage metals testing in the USA.

ISO 15587-1 (aqua regia digestion) and ISO 15587-2 (nitric acid digestion) are widely used to digest metals for wastewater, effluent, surface and drinking water testing protocols, while ISO 17294-2:2016 specifies the method to determine levels of 62 elements, which have been identified as dangerous using inductively coupled plasma-mass-spectrometry (ICP-MS) technology. These dictate both the detection processes and the allowable concentrations in drinking, surface, ground and wastewater.

As per regulatory requirements, not only is the final detection data determined by ICP-MS, sample collection, preparation, and testing methods also need to be in line with the relevant ICP-MS technology. With the advent of technology, ICP-MS detection is continually evolving, which means, labs have to keep adapting their workflows to both the regulatory expectations and advancements in this technology.

Additionally, environmental testing labs are always looking for an edge to remain competitive. One of the first tools acquired to improve detection quality is the latest ICP-MS machinery. Nowadays, labs can accurately determine metals levels in the parts per billion (ppb) or even parts per trillion (ppt). However, these diminishing limits inevitably increase the risks of contamination.

Contamination in metals detection workflows

Great importance is always placed on the final analysis step in a metals detection protocol, but contaminations can be introduced at any point in the workflow. Cleanliness, air quality, reagents, and human error can all be equally important; so, streamlining and optimising the entire workflow is crucial for obtaining accurate and reliable results.

Looking at the metals detection process, the metals digestion step seems to be the prime point where contaminations are introduced. Complete digestion can take up to 5 hours, the longest step in the workflow, allowing more time for potential contamination events. Metals digestion also involves adding foreign chemicals and applying reaction conditions; both of which can increase contamination risks. It is therefore important to carefully isolate samples throughout the lengthy digestion step.
