Oversight of Next Generation Nanotechnology

Since 1980, the capability of the federal agencies responsible for environmental health and safety has steadily eroded. The agencies cannot perform their basic functions now, and they are completely unable to cope with the new challenges they face in the 21st century. This paper describes some of these challenges, focusing on next-generation nanotechnologies, and suggests changes that could revitalize the health and safety agencies.

Médecine et rayonnements ionisants

Une nouvelle fiche d'aide à l'analyse des risques en radiologie dentaire endobuccale est suivie de la mise à jour de la fiche "Textes applicables" qui prend en compte l'évolution de la réglementation et annule la précédente (ED 4247). Elle appartient à une série publiée dans la revue "Documents pour le Médecin du Travail" depuis 2004, aujourd'hui disponible sur le site de l'INRS (www.inrs.fr) ou sur celui de la revue DMT (www.dmt-prevention.fr).
Ces fiches ont été élaborées par un comité scientifique multidisciplinaire associant plusieurs institutions et différents experts et font suite à une enquête sur la radioprotection menée en Ile-de-France .

La surveillance biologique des expositions professionnelles aux produits chimiques en France

État des lieux en 2006 et analyse comparative des prescriptions et de l'activité des laboratoires spécialisés entre 2002 et 2006.

Afin de combler le manque de connaissances sur la pratique de la biométrologie en médecine du travail, une enquête a été menée auprès des principaux laboratoires de toxicologie français. Il en ressort que le nombre de prescriptions est en augmentation, notamment les dosages urinaires relatifs à la surveillance des expositions aux substances CMR, au premier rang desquelles demeure le plomb.
Mais, malgré l'impact incitatif que semblent avoir eu les évolutions réglementaires, le nombre de salariés suivis reste globalement faible. La discussion sur les causes possibles de ce manque de recours à la biométrologie confirme le besoin d'un renforcement de la formation médicale et laisse entrevoir l'intérêt d'une base nationale du suivi biologique des expositions en France.

Adult Blood Lead Epidemiology and Surveillance

Overexposure to inorganic lead continues to be an important health problem worldwide. Furthermore, recent research has caused increased concerns about the toxicity of lead at low doses. Lead can cause acute and chronic adverse effects in multiple organ systems, ranging from subclinical changes in function to symptomatic, life-threatening intoxication. Since 1992, CDC's state-based Adult Blood Lead Epidemiology and Surveillance (ABLES) program has tracked laboratory-reported elevated blood lead levels (BLLs) in U.S. adults. The vast majority (95%) of reported elevated BLLs have been work related. One of the Healthy People 2010 national public health objectives is to reduce to zero the prevalence of BLLs ≥25 µg/dL among adults (objective 20-7). ABLES surveillance results through 2004 have been published previously. This report summarizes results for the period 2005--2007. An overall decline in national rates of elevated BLLs among state residents plus nonresidents from 14.0 in 1994 to 7.8 in 2007 has been observed.

Australian Labor Unions Concerned About Nanoscale Materials in the Workplace

The Australian Council of Trade Unions (ACTU) was created in 1927 and claims to represent the interests of 2 million workers. The ACTU published a Fact Sheet earlier this month explaining why its members are (or should be) concerned about nanotechnology.

Are some chemicals more dangerous at low doses?

There are some 82,000 chemicals used commercially in the U.S., but only a fraction have been tested to make sure they're safe and just five are regulated by the U.S. Environmental Protection Agency (EPA), according to congressional investigators. But a government scientist says there's no guarantee testing actually rules out health risks anyway.

Multifaceted Approach to Assess Indoor Environmental Quality
  • Of new-onset asthma cases in adults, 15–23% are work-related asthma
    [American Thoracic Society 2004]
  • The highest percentage of work-related asthma occurred among operators, fabricators, and laborers (32.9%)
    [Worker Health Chartbook 2004]
  • Between 35 and 60 million of the 89 million indoor environment workers have building-related symptoms of eye, nose, and throat irritations or headache and fatigue
    [Mendell 2002]
  • The points above very briefly highlight some of the issues related to indoor environmental quality. It has been estimated that indoor environmental quality-related health issues cost businesses in the range of $20–70 billion annually due to lost productivity, decreased performance, and sick absences. Some of these health effects include respiratory issues that could fall under the classification of work-related asthma.

    Compensation for Night Work / Breast Cancer Link

    Thirty-seven Danish women will be compensated for breast cancer linked to their night shift work, according to the Danish National Board of Industrial Injuries. Denmark's workers compensation system is the first in the world to recognize the link between working night shifts and the development of breast cancer. Evidence of this link though has been mounting.

    Respiratory hazards of poultry dust

    Recent research into the incidence of ill health in agriculture in Great Britain reported a high prevalence of respiratory symptoms in poultry farm workers, who can be exposed to significant amounts of airborne dust (poultry dust) generated during poultry work activities. Both acute and chronic work-related symptoms have been reported in poultry workers and the range of symptoms suggests that poultry dust may cause harm by various mechanisms, including allergic reaction and direct irritancy. Strong evidence exists to support a risk of occupational asthma associated with exposure to certain components in the dust.

    Nanotechnology: Human and Environmental Exposure Assessment of Nanomaterials Workshop

    Determining whether a material or substance poses an occupational health risk depends on knowing not only the potential toxic characteristics of the material, but also the characteristics of exposure. To what concentrations are workers exposed, for how long, and in what ways? In research to answer the question of whether nanomaterials pose work-related health risks, exposure assessment is particularly vital. Because of the relative newness of nanotechnology, very little exposure data have been reported in the scientific literature. At this stage, measuring or determining risk becomes a little like trying to solve a mystery when major clues are missing. Scientists and engineers face this challenge even as the market for nanotechnology grows, and along with it, an increasing demand from diverse parties for guidance to underpin its responsible development.

    Approaches to Safe Nanotechnology

    This document reviews what is currently known about nanoparticle toxicity, process emissions and exposure assessment, engineering controls, and personal protective equipment. This updated version of the document incorporates some of the latest results of NIOSH research, but it is only a starting point. The document serves a dual purpose: it is a summary of NIOSH's current thinking and interim recommendations; and it is a request from NIOSH to occupational safety and health practitioners, researchers, product innovators and manufacturers, employers, workers, interest group members, and the general public to exchange information that will ensure that no worker suffers material impairment of safety or health as nanotechnology develops.
