Wood preservatives with PCP and lindane

Wood preservative roof

Wood preservatives containing the hazardous substances PCP and lindane were mainly used in the 1960s and 1970s to protect roof beams and even wooden toys. These are highly volatile pollutants (SVOCs) that can continue to outgas indoors for decades and accumulate in house dust, causing health problems and even cancer.

Air pollutants in small combustion plants

Chimney fires - small firing systems

Small combustion plants

Small combustion plants are usually operated with fossil fuels such as natural gas, heating oil, coal or wood . They are designed for private use and small businesses.

According to the 1st BImSchV (Ordinance on Small and Medium-Sized Combustion Plants), all plants with a rated thermal input of less than 1000 kW are considered small combustion plants.

PCBs in old capacitors

Fluorescent tubes Capacitors

Polychlorinated biphenyls (PCBs) were until the 90s as insulating agents in old capacitors, fluorescent lamps, household appliances, paints, plastics and plasticizers. They continue to pose a health risk today. In many cases, old devices such as fluorescent tubes with PCB-contaminated small capacitors are still in use. The harmful PCB-contaminated insulating fluid can leak out of these.

Kale – bioindicator for pollutants

Kale in a bowl

Kale is considered a superfood and is a bioindicator for air pollutants and contaminated soils. Active biomonitoring, with biologically standardized measurement methods, can be used to determine and assess the effects of air pollution and other stresses on the environment and humans.

Inhalation of hazardous substances – Sampling with SG10-2 and PM4-2

Longe 3D picture


The inhalation of hazardous substances at the workplace and in other areas can lead to damage to health and even serious cancer in the event of prolonged exposure. Clear occupational health and safety regulations are in place to protect health and prevent possible illnesses caused by inhaling hazardous substances.

Measure occupational limit values GSA SG10-2 and PM4-2 devices

Measuring devices PM4-2 and SG10-2

The occupational limit values describe the maximum permitted exposure to a substance at the workplace. This is based on regular contact over a 40-hour working week (5 days of 8 hours each). Important safety measures at the workplace can be derived from the results obtained.

Technical rules for hazardous substances – TRGS 900

Dust measurement

Behind the abbreviation TRGS stands for the Technical Rules for Hazardous Substances. These rules reflect the current state of the art, scientific findings for activities involving hazardous substances, including their classification and labeling. They are drawn up by the Committee for Hazardous Substances (AGS) and published by the Bundesministerium für Arbeit und Soziales (BMAS). The Hazardous Substances Ordinance can also be consulted.

Testing heavy metal exposure with GSA measuring devices SG10-2A and PM4-2

GSA Measuring device SG10-2A

GSA measuring devices SG10-2A and PM4-2 determine the heavy metal load

If there is a risk of heavy metal exposure at the workplace, it often makes sense to test for heavy metal exposure. It is important to consider a few points in advance. Our GSA measuring devices SG10-2A or PM4-2, for example, are suitable for this purpose.

These devices can be used to measure the particle measurements of the dust fraction of A-dust and/or E-dust.

Measuring diesel engine emissions with PM4-2 measuring device

Measuring diesel engine emissions

Measuring diesel engine emissions with PM4-2 measuring device

Diesel engine emissions (DEE) can be determined with our PM4-2 measuring device. To measure diesel engine emissions, it generates a constant air volume flow. Furthermore, fluctuations in the air during sampling of diesel engine emissions can be compensated for by pressure and temperature compensation. This means that precise measurements of diesel engine emissions can be carried out despite fluctuating weather conditions and temperatures.

Measuring quartz dust – Occupational safety

Measuring quartz dust with GSA PM4-2 and SG10-2 measuring devices

If quartz dust is present at the workplace, measures such as measuring quartz dust are a sensible occupational health and safety measure.

We offer two systems for this purpose: Firstly, the measuring device PM4-2 with A-dust head for stationary measurement and the measuring devices SG10-2 with fine dust sampling system 10 (according to IFA) for personal measurement at the workplace.
