Description
1,2,3,5,7,8-Hexachloronaphthalene is a polychlorinated naphthalene compound, which is a type of persistent organic pollutant (POP). It is characterized by its hexachlorinated structure, making it a stable and lipophilic substance. Due to its chemical properties, it has been used in various applications, particularly in environmental testing and research.
Uses
Used in Environmental Testing and Research:
1,2,3,5,7,8-Hexachloronaphthalene is used as a standard for environmental testing and research to analyze and monitor the presence of persistent organic pollutants in various ecosystems. Its stability and lipophilic nature make it an ideal candidate for such studies.
Used in Human Adipose Tissue Studies:
In the field of environmental health, 1,2,3,5,7,8-hexachloronaphthalene is used as a substance for studying the bioaccumulation of polychlorinated naphthalenes in human adipose tissue. This helps researchers understand the exposure levels and potential health risks associated with these pollutants in the population.
Used in Breast Milk Analysis:
1,2,3,5,7,8-Hexachloronaphthalene is also utilized in the analysis of multi-persistent organic pollutants in breast milk of first-time mothers. This application aids in assessing the exposure of infants to these harmful substances through breastfeeding and contributes to the understanding of the potential impact on infant health and development.
Check Digit Verification of cas no
The CAS Registry Mumber 103426-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,2 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103426-94:
(8*1)+(7*0)+(6*3)+(5*4)+(4*2)+(3*6)+(2*9)+(1*4)=94
94 % 10 = 4
So 103426-94-4 is a valid CAS Registry Number.

This paper presents emission factors (EFs) derived for a range of persistent organic pollutants (POPs) when coal and wood were subject to controlled burning experiments, designed to simulate domestic burning for space heating. A wide range of POPs were emitted, with emissions from coal being higher than those from wood. Highest EFs were obtained for particulate matter, PM10, (～ 10 g/kg fuel) and polycyclic aromatic hydrocarbons (～ 100 mg/ kg fuel for ΣPAHs). For chlorinated compounds, EFs were highest for polychlorinated biphenyls (PCBs), with polychlorinated naphthalenes (PCNs), dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) being less abundant. EFs were on the order of 1000 ng/kg fuel for ΣPCBs, 100s ng/ kg fuel for ΣPCNs and 100 ng/kg fuel for ΣPCDD/Fs. The study confirmed that mono- to trichlorinated dibenzofurans, Cl1,2,3DFs, were strong indicators of low temperature combustion processes, such as the domestic burning of coal and wood. It is concluded that numerous PCB and PCN congeners are routinely formed during the combustion of solid fuels. However, their combined emissions from the domestic burning of coal and wood would contribute only a few percent to annual U.K. emission estimates. Emissions of PAHs and PM 10 were major contributors to U.K. national emission inventories. Major emissions were found from the domestic burning for Cl1,2,3DFs, while the contribution of PCDD/F-ΣTEQ to total U.K. emissions was minor.
