Throughout the 18th and 19th centuries, arsenic was widely used in wallpaper and decorative furnishings, prized for the vivid green pigment it produced when combined with copper. Known commercially as Scheele’s Green and Paris Green, these arsenic-based dyes were used in wallpaper printing well into the Victorian period, most often in domestic bedrooms and parlours.
Although their dangers were eventually recognised, many properties constructed before the 20th century may still contain wallpaper, pigments, or glue contaminated with arsenic compounds. When disturbed, these materials can release toxic dust or gases that pose a serious health hazard to occupants and contractors.
At Envirochem, we test for the presence of arsenic in wallpaper, pigments, adhesives and surrounding materials. Our team combines laboratory analysis with site-specific advice to help you identify risks early, avoid accidental exposure, and plan safe remediation works.
What We Test For
We provide targeted sampling and laboratory testing for:
- Wallpaper samples suspected of containing arsenic-based pigments (e.g. Scheele’s Green and Paris Green)
- Wallpaper paste or glue with potential arsenic content
- Dust or debris in properties where arsenic wallpaper may have deteriorated
- Arsenic residues in underlying wall surfaces or insulation
- Arsine gas release potential under specific environmental conditions
Testing may be required as part of a pre-refurbishment survey, heritage building assessment, or investigation into unexplained ill-health associated with older interiors.
Our Process
We begin with a consultation to understand the age and condition of the building, the scope of any planned works, and the potential for disturbance. Where needed, we attend sites to collect samples of wallpaper, adhesive, or dust for analysis.
Samples are analysed in our UKAS-accredited testing laboratory (No. 1227) using validated methods capable of detecting trace levels of arsenic. Where risks are identified, we provide clear guidance on control measures, appropriate personal protective equipment (PPE), and safe removal or encapsulation procedures in line with current best practice.
We can also liaise with heritage consultants, local authorities, or contractors to ensure remediation plans balance safety with conservation requirements.
When Is Testing Required?
You may require arsenic wallpaper testing if:
- You are refurbishing or redecorating a pre-1900 property with original or period wallpaper
- You suspect the presence of green wallpaper pigments in an older domestic or heritage building
- There is evidence of unexplained respiratory illness or environmental sensitivity linked to a property’s interior
- Disturbance of old wallpaper or glue is likely during planned works
- You are managing a listed or conservation property and require non-destructive analysis
If you're unsure whether arsenic testing is appropriate, our consultants can advise on a proportionate and risk-led approach.
Compliance and Risk Considerations
Arsenic is a highly toxic substance and its release indoors, even in small amounts, can result in significant health consequences. Exposure risks include respiratory irritation, gastrointestinal distress, chronic fatigue, and in some cases, long-term organ damage. Children, pregnant individuals, and contractors are particularly vulnerable.
Whilst arsenic in wallpaper is not regulated under a single UK standard, its management is covered indirectly by several legal duties, including the Health and Safety at Work Act 1974, the Control of Substances Hazardous to Health (COSHH), and the Construction (Design and Management) Regulations 2015. If arsenic risks are foreseeable, failure to assess or manage them appropriately may result in enforcement action, reputational harm, or costly project delays. Early testing allows you to plan safe remediation, protect your workforce and occupants, and avoid exposure events that could lead to liability or litigation.
