PFAS
PFAS stands for poly- and perfluoroalkyl substances, a group of chemicals that have been used for decades in industrial applications and consumer products because of their water, grease and dirt-repellent properties. PFAS are highly persistent, meaning they (as a rule, i.e., with a few exceptions) do not degrade in the environment and accumulate in the bodies of humans and animals. Some PFAS substances are associated with health risks, such as increased risk of cancer, hormone disruption, liver damage and reduced immunity. At Normec Green Agro Control, we understand the urgency of detecting and managing PFAS contaminants in various environments, including soil, water and food.
Our specialized analyses are designed to accurately identify and quantify PFAS contaminants, complying with the latest standards and regulations. With our advanced technologies and in-depth expertise, we help protect human and environmental health.
It is estimated that there are more than 4,700 different PFAS compounds. This is because PFAS is a group of chemical compounds consisting of a fluorocarbon chain and several functional groups, such as sulfonic acid or carboxylic acid. These functional groups can be combined in different ways, leading to a wide variety of PFAS compounds.
Among the most well-known and researched PFAS compounds are perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), but there are many other PFAS compounds whose toxicity and persistence in the environment are not yet fully known.
PFAS can enter food, including fruits and vegetables, through a variety of ways. PFAS can enter the soil through such things as contaminated groundwater, contaminated manure, compost and wastewater. PFAS can also spread through air and water currents and get into the soil.
Although PFAS in AGF is not considered a major public health risk to date, eating food containing PFAS can contribute to overall exposure to these substances. It is therefore important to ensure safe production and distribution of AGF.
Several countries are therefore taking measures to reduce PFAS exposure through food. For example, in the Netherlands we grow fewer crops in certain regions due to soil contamination and lower standards or higher requirements are set for the amount of PFAS in drinking water and soil.
It is important to continue studying how PFAS are spread and to what extent they are present in different types of food to minimize health risks and ensure the safety of our food.
Several studies have been conducted on the presence of PFAS in eggs and it has been determined that eggs can be a source of exposure to these substances. PFAS can enter eggs through the soil, the feed given to chickens and through air and water streams in the environment of the poultry farm.
For example, a 2020 study in the Netherlands found that the amount of PFAS in eggs was higher near locations where many of these substances were found in the soil. The study also found that the amount of PFAS in eggs varied between different types of poultry farms and that organic eggs generally contained less PFAS than conventional eggs.
Until recently, it was only possible for farms to have eggs tested for the presence of PFAS. As a solution to the growing need for PFAS analyses for private chicken farmers, Testenoppfas.nl, together with Normec Groen Agro Control, is proud to introduce a new platform: TestenOpPFAS.nl. Through this online platform PFAS tests are now available to you in a simple and accessible way.
As with eggs and other foods, PFAS can also end up in fish. This can occur through various pathways, such as through the water and food chain, with PFAS entering the water and then being taken up by plankton and small fish, which in turn are eaten by larger fish.
Several studies have been conducted on the presence of PFAS in fish and in some cases high concentrations have been found. In particular, fish that feed at the top of the food chain, such as tuna, swordfish and shark, may contain higher levels of PFAS because of their accumulation in their tissues.
Although the presence of PFAS in fish is still under investigation, no direct health risks to humans have been identified when eating fish containing PFAS. However, fish intake may contribute to overall exposure to these substances, especially with frequent consumption of fish containing high levels of PFAS.
To reduce exposure to PFAS through fish, many countries are taking measures to reduce water and food chain pollution, as well as measures to reduce the amount of PFAS in fish, such as improving production processes and screening fish for PFAS.
PFAS can also end up in meat, although generally to a lesser extent than, for example, in fish. PFAS can enter meat through the feed given to livestock, contaminated drinking water, soil contamination and air pollution in the vicinity of the livestock farm.
Several studies have been conducted on the presence of PFAS in meat, finding high concentrations in some cases, especially in meat from animals exposed to contaminated environments. For example, near industrial areas, military bases or airports.
Although no direct health risks to humans have currently been identified from eating meat containing PFAS, it may contribute to overall exposure to these substances. It is therefore important to continue to monitor the presence of PFAS in meat and take measures to reduce exposure to these substances, such as improving nutrition and reducing livestock exposure to contaminated environments.
PFAS can enter water from a variety of sources, including industrial discharges, leaching from soil and ground, and the degradation of products containing PFAS, such as firefighting foam. In addition, rainwater can transport PFAS to surface water and groundwater.
PFAS are highly persistent and mobile in the environment, so they spread easily over long distances and accumulate in water bodies, such as rivers, lakes and groundwater aquifers. This can lead to high concentrations of PFAS in water, which can be harmful to the environment and ecology.
Long-term exposure to high concentrations of PFAS in drinking water can also have adverse health effects, such as increased risk of cancer, hormone disruption, liver damage and reduced immunity. For these reasons, international standards and guidelines are being developed to limit exposure to PFAS in drinking water. In addition, measures are being taken to prevent or reduce the spread of PFAS in water, such as reducing the use of PFAS-containing products and implementing remediation measures at contaminated sites.
PFAS can enter soil from a variety of sources, including industrial discharges, leaching from soil improvers and compost, and the degradation of products containing PFAS, such as firefighting foam and carpets. In addition, rainwater can transport PFAS into the soil.
PFAS are highly persistent and mobile in the environment, allowing them to spread easily over long distances and accumulate in soil. This can lead to high concentrations of PFAS in soil, which can be harmful to the environment and ecology.
Long-term exposure to high concentrations of PFAS in soil can also have adverse health effects, such as increased risk of cancer, endocrine disruption, liver damage and reduced immunity. For these reasons, international standards and guidelines are being developed to limit exposure to PFAS in soil. In addition, measures are being taken to prevent or reduce the spread of PFAS in soil, such as reducing the use of PFAS-containing products and implementing remediation measures at contaminated sites.
