Environment

The study of environmental samples includes chemical, physical and biological analysis of arrays naturally present in our environment – such as air, water, soil, sediment and biota.

We analyse both well-known environmental pollutants and new substances such as pharmaceutical residues. Analysis and testing are tailored to suit particular assignments, according to individual customer needs. Many of our measurement and analytical methods are accredited by Swedac. Other methods we employ are assessed using equivalent quality control procedures.

Air

We carry out numerous measurements targeting air quality that are unique of their kind. Our long experience of both gaseous air pollutants and particulate matter such as PM10 and PM2.5, allows us to offer simple and robust methods for cost-effective air quality monitoring, including the deployment of passive diffusion samplers.

We are frequently commissioned to determine the presence of nitrogen dioxide, ozone, VOCs and PAHs in ambient air. We can also determine metal particles and analyse both total and particulate mercury in the air. We develop new analytical methods that have the potential to target rare earth elements (REEs), for example, catalyst metals, isolated by our PM10 sampling.

Water

IVL is adept at tackling water pollution and acidification issues. Knowledge derived from long series of measurements carried out since the 1980s allows us to analyse the effects and impact of forest management practices, the impact of air pollution on water systems, the effect of industrial emissions on recipient areas as well as pollutant levels in wastewater.

We study the release and extent of water pollution and its nutritional and acidity status in forest areas. We specialize in analysing extremely low levels of contaminants including PAHs, PCBs, PFAs and mercury, and have extensive experience when it comes to establishing environmental concentrations trends.

Here are some examples of chemical analyses we perform on water: determination of inorganic base chemistry, ground element analysis, low-level incidence of mercury, PAHs, PCBs, PFAs, drug residues, pesticides, flame retardants and softeners in plastics.

Soil and sediment

IVL has many years research experience screening for environmental contaminants in soil and sediment. We carry out feasibility assessments; strategize sampling plans, perform sampling and analysis, conduct risk assessments and advise on action plans. PFAS pollution in soil is one of our areas of expertise.

We specialize in extremely low-level analyses of contaminants such as PAHs, PCBs, PFAs and mercury and are experienced in deploying environmental monitoring projects to audit concentrations trends in the environment.

Biota

We study the release and spread of water contaminants and how pollutants are taken up and affect biota such as fish and mussels. We target the entire process, including the strategizing of sampling plans, sampling, test fishing, and analysis, risk assessment and advice regarding action plans. The most common chemical analyses we perform are the determination of elemental analysis including mercury, PAHs (polycyclic aromatic hydrocarbon), PCBs (Polychlorinated biphenyl), PFAS (Perfluorinated alkylated substances), drug residues, pesticides, flame retardants and softeners in plastics.
