Article
Chlorinated paraffins (CPs) are complex mixtures, which consist of thousands of individual compounds with no dominant representative. Consequently, knowledge on structure and environmental relevance of individual CP congeners is poor. Similarly to the synthesis of individual CPs, the generation of less complex CP mixtures that can be thoroughly ana...
Article
The determination of chlorinated paraffins (CPs) has posed an intractable challenge in analytical chemistry for over three decades. The combination of an as yet unspecifiable number (tens - hundreds of thousands) of individual congeners in mass produced commercial CP mixtures and the steric interactions between them, contrive to defy efforts to cha...
Article
Full-text available
Background: The current production and use of chlorinated paraffins (CPs) at >1 million tons/y likely exceeds the lifetime production of polychlorinated biphenyls (PCBs). These persistent organic pollutants (POPs) are a concern to human health. Objectives: The United Nations Environment Programme conducts global surveys of human milk samples fro...
Article
Chlorinated paraffins (CPs) are high production volume chemicals currently produced and used in higher quantities than any other medium-size polyhalogenated compound (class). In addition, the composition of industrial CP mixtures is highly complex and poorly understood. In this article, we searched in the literature for the beginning of the chlorin...
Article
Short- and medium-chain chlorinated paraffins (SCCPs, MCCPs) are high-production volume industrial chemicals that have been previously reported to occur in food, packaging material and the environment. This study presents an assessment of dietary exposure for consumers in Southern Germany based on three different sampling approaches: (i) a classica...
Article
Infant formula and baby cereal are products specifically intended for a vulnerable consumer group and should therefore be strictly controlled. In this study, we analysed 21 infant formula and 10 instant baby cereal samples for the presence of chlorinated paraffins (CPs) and estimated dietary exposure to these compounds. Results covered short chain...
Article
The risk assessment of chlorinated paraffins (CPs), chemicals of widespread industrial use, is struggling without standardized analytical methods to obtain reliable occurrence data. Indeed, scientists face analytical challenges that hinder the comparability of analytical methods, among them uncontrolled ionization efficiency and lack of quantificat...
Article
Short-chained chlorinated paraffins (SCCP) and medium-chained chlorinated paraffins (MCCPs) are two of the main groups currently used to classify chlorinated paraffins (CPs). Since only SCCPs have been restricted by the Stockholm Convention, a robust but selective analysis with comparable results especially for SCCPs, but also for all other CPs is...
Conference Paper
Full-text available
Chlorinated paraffins (CPs) are a very complex class of flame retardants, plasticizers and high-pressure lubricants that are commonly divided into groups by the length of their carbon chain or their overall chlorination degree. Main groups are short-chain chlorinated paraffins (SCCPs, C 10-C 13 , 40-70% chlorine), medium-chain chlorinated paraffins...
Conference Paper
Full-text available
Chlorinated paraffins (CPs) are highly complex mixtures of different carbon chain lengths and chlorination degrees produced by radical chlorination of alkane feedstock. They are classified by their range of carbon chain lengths into short chain (SCCPs, C10-13), medium chain (MCCPs, C14-17) and long chain CPs (LCCPs, C>17). Based on publicly availab...
Article
The photolytic transformation of decabromodiphenyl ethane (DBDPE) - a current-use brominated flame retardant (BFR) and major substitute of the structurally related decabromodiphenyl ether - was investigated in different solvents (toluene, dichloromethane, chlorobenzene and benzyl alcohol). The transformation rate followed pseudo first order kinetic...
Article
Chlorinated paraffins (CPs) are complex mixtures of persistent contaminants present throughout the aquatic food web. In this study 122 farmed and 11 wild salmon samples were collected over the course of four years (2014–2017). The ratio of short-chain CP and medium-chain CP and the corresponding homologue patterns were determined by means of gas ch...
Article
For decades, high quantities of short-chain chlorinated paraffins (SCCP) and medium-chain chlorinated paraffins (MCCP) have been widely used, for instance as plasticizers or flame retardants, leading to global pollution due to unintentional emissions from products or waste. Due to the high complexity of chlorinated paraffins with several thousand c...

Project
Testing if available sample extracts are fit for screening and adapting a previously established quantification method to gain an overview of DBDPE occurrence in food samples
Project
The EURL POPs is working with experts from around Europe to establish CP analysis as part of official food control. Main challenges are finding comparable methods and all necessary standards so that reliable occurrence data can be produced.
