DTSC’s Perspective on PFASs in Carpets, Rugs, Indoor Upholstered Furniture, and Their Care and Treatment Products

André Algazi, Lead

Chemical and Product Evaluation Team

Safer Consumer Products framework

As designated by 23 authoritative bodies

Product-Chemical combinations that may cause harm

Manufacturer evaluation of alternatives

DTSC considers range of possible responses

Scope of this workshop

Polyfluoroalkyl and Perfluoroalkyl Substances (PFASs)

Over 3000 man-made chemicals

Used since the 50’s, e.g. to make products non-stick, waterproof, soil/stain/oil-resistant

At least one carbon fully fluorinated (i.e. no more C-H bonds)

3

δ+C ___ F

δ-

One of the strongest bonds in chemistry, leads to environmental persistence

4

OECD (2016); http://www.oecd.org/test-pfc/pfass/

Per- and polyfluoroalkyl substances (PFASs)

5

All PFASs are SCP Candidate Chemicals

The class is on Biomonitoring California’s Priority Chemicals list

Priority Product selection principles

• Potential exposure to the Candidate Chemicals in the product

AND

• Potential for exposures to contribute to or cause significant or widespread adverse impacts

6

2015 – 2017 Priority Product Work Plan

Identifies five policy priorities:• Clear exposure pathways to Candidate Chemicals

• Chemicals detected in biomonitoring studies

• Chemicals observed in indoor air and dust

• May impact children or workers

• May adversely impact aquatic resources, or observed through water quality monitoring

Identifies seven product categories

Lists example chemicals 7

Clothing

Beauty, Personal Care, and Hygiene Products

PFASs are in all the 2015-2017 Work Plan product categories

Building Products

Cleaning Products

Fishing and Angling Equipment

Office Machinery (Consumable Products)

Household/ Office Furniture & Furnishings

Scope of this workshop

Carpets and rugs

Exposure concerns

Ubiquity in the environment

Environmental persistence

Bioaccumulation

Long or non-negligible elimination half-lives

Presence in nearly all humans tested

Multiple routes for PFAS exposure

14

15

PFASs may have potential adverse impacts

Aquatic toxicity and terrestrial ecotoxicity

Endocrine disruption

Immunotoxicity

Neurotoxicity

Developmental toxicity

Cancer (testicular and kidney)

Organ toxicity

The PFAS market is changing

Reduced emissions of PFOA, its precursors, and related longer-chain PFASs

Shift from longer-chain PFASs to shorter-chains, fluorinated ethers, branched and cyclic compounds (“novel” PFASs)

Some PFAS-free products available

16

Shorter half-lives in humans

Faster elimination rates

Less toxic than legacy PFASs

Lack of evidence for ecotoxicity

Newer PFASs – safer?

17

Non-negligible half-lives in humans and biota

Environmental persistence

Mobility in the environment

Accumulation in plants

Lack of safety data

Newer PFASs – safety concerns?

18

All 2015-2017 policy priorities are met

Clear exposure pathways to Candidate Chemicals

Chemicals detected in biomonitoring studies

Chemicals observed in indoor air and dust

May impact children or workers

May adversely impact aquatic resources, or observed through water quality monitoring
