USA risk losing global leadership in nanotech


According to a new report from Lux Research, “In terms of sheer volume, The U.S. dominated the rest of the world in nanotech funding and new patents last year (…). But (…) countries such as China and Russia launched new challenges to U.S. dominance in 2009, while smaller players such as Japan, Germany and South Korea surpassed the United States in terms of commercializing nanotechnology and products.” (press release)

Friends of the Earth new (short) report : “Manufactured nanomaterials and sunscreens : top reasons for precautions”


Friends of the Earth together with ICTA and Consumers Union released today a 10 page report entitled “Manufactured nanomaterials and sunscreens : top reasons for precautions“. According to them these reasons are :

– Nanomaterials are different from other conventionally-sized compounds

– In the body, nanomaterials have much greater access to vulnerable organs and tissues

– Increasing evidence that some nanomaterials can pass through the skin

– Senior scientists have called for mandatory premarket safety tests for nanomaterials before they are used in products

– Potential next generation harm from nanomaterials

– Potential harm to workers and the Environment

– Nanomaterials in sunscreens and cosmetics could theoretically cause skin damage over time

– Consumers can get highly effective transparent protection from harmful rays of the sun with products made without nanoscale chemical ingredients.

Further details are available in the document.

EPA draft report : “Nanomaterial case studies : nanoscale titanium dioxide in water treatment and in topical sunscreen”


The EPA released this July for review and public comment a draft version of a (rather huge) report entitled “Nanomaterial case studies : nanoscale titanium dioxide in water treatment and in topical sunscreen” (222 p).

According to the preamble (p 14) : ” (…) This document is a starting point to determine what is known and what needs to be known about selected nanomaterials as part of a process to identify and prioritize research to inform future assessments of the potential ecological and health implications of these materials. Two specific applications of nanoscale titanium dioxide (nano-TiO2) are considered: as an agent for removing arsenic from drinking water and as an active ingredient in topical sunscreen. (…)

Chapter 1 – Introduction

Chapter 2 – Life cycle stages : “This chapter discusses the life cycle of nanoscale titanium dioxide (nano-TiO2) as either a water treatment agent or an ingredient in topical sunscreen. Each stage in the life cycles of the respective applications is considered from the standpoint of potential releases to the environment.

Chapter 3 – Fate and transport : This chapter “explores what might happen to nanoscale titanium dioxide (nano-TiO2) after it is released to the environment at various stages of the product life cycles for water treatment agents or topical sunscreens.

Chapter 4 – Exposure-dose characterization : “This chapter examines the potential for biota and humans to be exposed to nanoscale titanium dioxide (nano-TiO2) and associated pollutants through various environmental pathways tracing back to the life cycle of two types of applications of nano-TiO2, water treatment agents and topical sunscreens.

Chapter 5 – Characterization of effects : “This chapter provides information on the factors that influence nano-TiO2 ecological and health effects (Section 5.1), the ecological effects of nano-TiO2 (Section 5.2), and the toxicological and human health effects of nano-TiO2 (Section 5.3).

As stated on the dedicated EPA web page, “each chapter includes a list of questions that reflect information gaps in that portion of the document. Some of these information gaps or research needs are specific to the respective uses of nano-TiO2 either as a water treatment agent or as an ingredient in topical sunscreen. Other research needs may apply more broadly to nano-TiO2 irrespective of its application, and still other needs may apply even more widely to nanomaterials in general.

Nanotechnology & sunscreens – EWG’s 2009 investigation


The Environmental Working Group (EWG) reviews the situation concerning nanoparticles in sunscreens in a dedicated section of its  2009 sunscreen guide, released today. I find particularly interesting this paragraph of their investigation’s contrasted conclusion : “When we began our sunscreen investigation at the Environmental Working Group, our researchers thought we would ultimately recommend against micronized and nano-sized zinc oxide and titanium dioxide sunscreens. After all, no one has taken a more expansive and critical look than EWG at the use of nanoparticles in cosmetics and sunscreens, including the lack of definitive safety data and consumer information on these common new ingredients, and few substances more dramatically highlight gaps in our system of public health protections than the raw materials used in the burgeoning field of nanotechnology. But many months and nearly 400 peer-reviewed studies later, we find ourselves drawing a different conclusion, and recommending some sunscreens that may contain nano-sized ingredients“.

The Nanotechnology & Sunscreen section of the guide more precisely reviews the following issues :

* Safety concerns of nanoparticles

–> potential for human uptake of nanoparticles by skin absorption/penetration (for TiO2 and ZnO nanoparticles)

–> dermal penetration of other nanoparticles

–> oral exposures to nanoscale zinc and titanium

–> inhalation exposures to nanoscale zinc and titanium

* Toxicity of nano-scale zinc and titanium

* Nano-scale zinc and titanium life-cycle and environmental risks

The Impact of nanoparticles section of the guide includes lists of titanium and zinc nanoparticle suppliers.

OSHA report : “Literature review – Workplace exposure to nanoparticles”


The European Agency for Safety and Health at Work (EU-OSHA) recently published a report entitled “Literature review – Workplace exposure to nanoparticles” which reviews the most recent publications on nanoparticles and focuses on the possible adverse health effects of workplace exposure. The document also presents the regulatory background and activities taken to manage this emerging risk.

Nano & biocidal silver – Friends Of the Earth report


Friends of the Earth (FoE) released yesterday a report entitled   “Nano & biocidal silver – extreme germ killers present a growing threat to public health” (press release).

In the frame of this document, the NGO calls for “immediate moratorium on the commercial release of products that contain manufactured nanosilver until nanotechnology-specific regulation is introduced to protect the public, workers and the environment from their risks, and until the public is involved in decision-making“.

The report is rather dense with informations and documented with a lot of references. A very interesting part focuses on nanotechnology regulatory issues and discusses the European, Australian and US situations in this matter (pages 26-33 of the report).
