Denmark just became the first country to ban PFAS from food packaging

Denmark will be the first country to ban PFAS Chemicals, which have been linked to cancer, elevated cholesterol and decreased fertility, from food packaging, starting next year.

PFAS substances, sometimes called "forever chemicals" because they don't break down in the environment, are used to repel grease and water in packaging for fatty and moist foods such as burgers and cakes.

What are PFAS chemicals, and what are they doing to our health?

"I do not want to accept the risk of harmful fluorinated substances (PFAS) migrating from the packaging and into our food. These substances represent such a health problem that we can no longer wait for the EU," Denmark's Food Minister Mogens Jensen said in a statement Monday.

PFAS chemicals are a family of potentially thousands of synthetic chemicals that are extremely persistent in the environment and in our bodies. PFAS is short for perfluoroalky and polyfluoroalkyl substances, and includes chemicals known as PFOS, PFOA and GenX.

They are all identified by signature elemental bonds of fluorine and carbon, which are extremely strong and what make it so difficult for these chemicals to disintegrate in the environment or in our bodies.

Under Denmark's new regulation, baking paper and microwave popcorn bags, for example, will be required to be manufactured without any PFAS.

"We congratulate Denmark on leading the way for healthier food and hope this will encourage similar action across the EU, the US and worldwide," said Arlene Blum of the Green Science Policy Institute and the Department of Chemistry at University of California, Berkeley.

FDA confirms PFAS chemicals are in the US food supply

"Given the potential for harm, we must ask if the convenience of water and grease resistance is worth risking our health," Blum said.

PFAS chemicals have been manufactured since the 1940s and can be found in Teflon nonstick products, stains and water repellants, paints, cleaning products, food packaging and firefighting foams.

These chemicals can easily migrate into the air, dust, food, soil and water. People can also be exposed to them through food packaging and industrial exposure.

A growing body of science has found that there are potential adverse health impacts associated with PFAS exposure, including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.

In a statement, the Danish Veterinary and Food Administration said that the substances were very difficult to break down in the environment, and some of them accumulate in humans and animals.

The ban covers the use of PFAS compounds in food contact materials of cardboard and paper. The Danish government said it would continue to be possible to use recycled paper and paper for food packaging, but said PFAS compounds must be separated from the food with a barrier which ensures that they don't migrate into the food.

PFOS and PFOA are the two most-studied PFAS chemicals and have been identified as contaminants of emerging concern by the US Environmental Protection Agency.

PFOS was voluntarily phased out of production in the United States by 3M, the main manufacturer, starting in 2000. In 2006, PFOA began to be phased out as well. PFOA and PFOS are no longer manufactured or imported in the United States, but similar "replacement chemicals for PFOA and PFOS such as GenX, may be just as persistent," Susan M. Pinney, a professor in the Department of Environmental Health at the University of Cincinnati.

The European Food Safety Agency said it is reassessing the risks PFAS pose to human health and will report on its findings in the near future.

Wellington Laboratories offer a wide range of Certified Reference Standards for Testing and Analysis of Perfluorinated Compounds.

 Perfluorinated Compounds (PFCs) 

Per- and Polyfluoroalkyl Substances (PFAS) are an emerging class of environmental contaminants. Their unique properties create a host of analytical challenges that require the use of native and mass-labelled standards for the generation of accurate data.

The most notable PFAS include PFOS (perfluorooctanesulfonate) and PFOA (perfluorooctanoic acid) and Wellington currently offers multiple mass-labelled standards for these compounds to meet your analytical needs. In fact, Wellington offers a large selection of native and mass-labelled per- and poly-fluorinated compounds, including:

Denmark just became the first country to ban PFAS from food packaging

Denmark will be the first country to ban PFAS Chemicals, which have been linked to cancer, elevated cholesterol and decreased fertility, from food packaging, starting next year.

PFAS substances, sometimes called "forever chemicals" because they don't break down in the environment, are used to repel grease and water in packaging for fatty and moist foods such as burgers and cakes.

What are PFAS chemicals, and what are they doing to our health?

"I do not want to accept the risk of harmful fluorinated substances (PFAS) migrating from the packaging and into our food. These substances represent such a health problem that we can no longer wait for the EU," Denmark's Food Minister Mogens Jensen said in a statement Monday.

PFAS chemicals are a family of potentially thousands of synthetic chemicals that are extremely persistent in the environment and in our bodies. PFAS is short for perfluoroalky and polyfluoroalkyl substances, and includes chemicals known as PFOS, PFOA and GenX.

They are all identified by signature elemental bonds of fluorine and carbon, which are extremely strong and what make it so difficult for these chemicals to disintegrate in the environment or in our bodies.

Under Denmark's new regulation, baking paper and microwave popcorn bags, for example, will be required to be manufactured without any PFAS.

"We congratulate Denmark on leading the way for healthier food and hope this will encourage similar action across the EU, the US and worldwide," said Arlene Blum of the Green Science Policy Institute and the Department of Chemistry at University of California, Berkeley.

FDA confirms PFAS chemicals are in the US food supply

"Given the potential for harm, we must ask if the convenience of water and grease resistance is worth risking our health," Blum said.

PFAS chemicals have been manufactured since the 1940s and can be found in Teflon nonstick products, stains and water repellants, paints, cleaning products, food packaging and firefighting foams.

These chemicals can easily migrate into the air, dust, food, soil and water. People can also be exposed to them through food packaging and industrial exposure.

A growing body of science has found that there are potential adverse health impacts associated with PFAS exposure, including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.

In a statement, the Danish Veterinary and Food Administration said that the substances were very difficult to break down in the environment, and some of them accumulate in humans and animals.

The ban covers the use of PFAS compounds in food contact materials of cardboard and paper. The Danish government said it would continue to be possible to use recycled paper and paper for food packaging, but said PFAS compounds must be separated from the food with a barrier which ensures that they don't migrate into the food.

PFOS and PFOA are the two most-studied PFAS chemicals and have been identified as contaminants of emerging concern by the US Environmental Protection Agency.

PFOS was voluntarily phased out of production in the United States by 3M, the main manufacturer, starting in 2000. In 2006, PFOA began to be phased out as well. PFOA and PFOS are no longer manufactured or imported in the United States, but similar "replacement chemicals for PFOA and PFOS such as GenX, may be just as persistent," Susan M. Pinney, a professor in the Department of Environmental Health at the University of Cincinnati.

The European Food Safety Agency said it is reassessing the risks PFAS pose to human health and will report on its findings in the near future.

2,7-Dibromo-9H-carbazole Certified Reference Standard

Halogenated carbazoles have recently been recognised as emerging environmental contaminants. Although there exact source has not been determined, both modern and historic sources (LED manufacturing and halogenated indigo dyes respectively) have been suggested. Since certain halogenated carbazole congeners can be lost during acid silica clean-up, it is very important that reference standards be used to monitor recoveries when processing samples.

Why filter your samples for HPLC?

• To protect the HPLC column, the column inlet frits and capillary columns against blockage (plugging) caused by particulate matter in the sample
• To protect injection valves from damage caused by scratching and wear of the valves internal components, caused by harmful particulate matter in the unfiltered sample, thereby reducing instrument downtime.

About our Quality Control procedures

• Every batch of filters is tested by an independent laboratory to ISO 17025 quality procedures

• Every individual Q-Fil Certified Syringe Filter is visually inspected to ensure it meets our manufacturing and quality control specifications
• Samples of all our syringe filters and their respective raw technical data are stored for a period of 5 years from the date of manufacture for future reference
• Each batch of filters is tested prior to release for
- External Dimensions
- Bubble Point
- Burst Pressure
- Filter Integrity
- Water Flow Rate
- UV Extractables and compliance with all technical procedures

Why use Greyhound Q-Fil Certified Syringe Filters?

• Q-Fil Certified Syringe Filters are manufactured in compliance with ISO 9001:2000 quality procedures

• Every box is supplied with a Certificate of Analysis and Conformance to guarantee its batch to batch quality and performance
• The unique encapsulating process developed for these filters, forces the sample to pass only through the membrane, thus avoiding the possibility of leaks or contamination

• Excellent resistance to all routinely used HPLC solvents
• Filter housings are manufactured from high density medical grade polypropylene
• Extremely low level of extractables for highly sensitive work
• Luer connections fully comply with ISO 594-1
• Filters are available with standard and ‘SlimTip’ sized outlets

Selecting the right Q-Fil Certified Syringe Filter

• Choose the size of filter based on the volume of sample to be filtered

• Choose the filters porosity based on the size of the potential particulates in the sample. It is important to be aware that the finer the porosity of the membrane the greater the pressure will be required to pass the sample through the filter. A sample containing large quantities of particulates is best filtered using a filter with a built-in glass fibre pre-filter
• Choose the type of membrane based on the solvent being filtered.

Filter Sizes

All our filters have female Luer Lock inlets and are available in three diameters -

25mm Diameter
Designed for large sample volumes or solvent filtration
Wide cross sectional area 3.55cm2
Maximum filtration volume >10ml
Maximum operating pressure 550 Kpa

13mm Diameter
Suitable for most applications
Filtration area of 0.95cm2
Maximum filtration volume 1 to 10ml Maximum operating pressure 750 Kpa Now available with ‘SlimTip’ (ST) outlet

4mm Diameter
Suitable for most applications Ideal for small samples <1ml Pore sizes of 0.20µm and 0.45µm
SlimTip Filters (ST)
13mm diameter syringe filters are now available with the new ‘SlimTip’ outlet for direct filling of microvials.

Pore Sizes

Q-Fil Certified Syringe Filters are available in 0.20µm and 0.45µm pore sizes. The 0.20µm filters remove the smallest particulates whilst the 0.45µm filters are designed to remove particulates which would be detrimental to most analytical columns.

Pre-filters (page 6) have a glass microfibre membrane which is chemically inert and resists most solvents. Q-Fil glass microfibre pre-filters are recommended for removing large particulates from the sample and are ideal for dissolution tests.

Glass microfibre membranes are also available mounted before the microporous filter membrane in the polypropylene housing. The glass pre-filter removes the larger particulates and prevents premature clogging of the filter.

PFAS analysis in fish tissue by HPLC-MS/MS 

Development of extraction and cleanup approachesfor PFASsanalysis in fish tissue by HPLC-MS/MS technique

A V Sorokin, V V Ovcharenko, K A Turbabina, A I Kozhushkevich, A M Kalantaenko, A A Komarov

The Russian State Center for Quality and Standardization of Veterinary Drugs and Feed (VGNKI), Moscow, Russia, 123022

Abstract. The history of PFASs emergence and current status in the context of the Stockholm Convention on POPs, their environmental distribution and toxicity are discussed. Various approaches to PFASs analysis in fish tissues are discussed. An original method of sample preparation is described, which allows quantitative PFASs determination at 0.2 – 100 ppb levels.

1.   Introduction

Perfluorinated compounds (PFASs), classified according to the recommended terminology [1], are a large family of technogenic contaminants. The family consist of different compound classes, such as carboxylates, sulfonates, sulfonamides, alcohols and etc., of which carboxylates and sulfonates are most often analysed in laboratories. PFASs started to emerge into the environment in the late 40s as by-products of Teflon development by DuPont. Teflon was approved by FDA for kitchenware coating in 1962, and Zonyl was approved for food packaging in 1967. At present, PFASs are used in textile industry, paper production, as components in various resins, foams, etc. Accordingly, perfluorooctanoic acid (PFOA) (Fig. 1) was first detected in the blood samples of factory personnel in 1978, and in the ground water in 1984. Due to toxicity concerns, some companies stopped producing 8-carbon PFAS since 2000.

PFASs are stable contaminants capable of bioaccumulation, they are detected in animal tissues. At present, the worldwide production of PFASs has been reduced due to information about their potential health risks, including risks of cancer promotion. According to the European Union data on PFAS in food collected in 2006 – 2012, perfluoroalkanesulfonates (PFSAs) and perfluoroalkylcarboxylicacids (PFCAs) are the most widespread food contaminants. PFSAs were mostly found in fish, meat, drinking water and fruits. The highest levels were detected in liver samples.

High levels of PFCAs and PFSAs were found in marine mammals feeding on fish in such industrially developed areas as the Baltic Sea, Mediterranean, the Great Lakes, and along the South East Asia coast, but also in such remote areas as Alaska and the Antarctic (Table 1).

 Most common approaches to PFASs extraction and cleanup involve methanol, acetonitrile, and their mixtures with acidic or alkaline modifications followed by SPE cleanup on commercial sorbents.  Here we report on the determination of perfluorinated carboxylates and sulfonates in medium-fat fish tissues using an alternative method of lipids removal described below.
