Real-time measurement of nitrogen monoxide in tunnels and its oxidation rate in diluted diesel exhaust

Exposure to oxides of nitrogen (NOx which denotes the mixture of nitrogen monoxide, NO, and nitrogen dioxide, NO2) commonly arises in the tunnelling industry from diesel engine exhaust emissions and from the use of explosives. The British Tunnelling Society (BTS) guidance levels for NO are 5 ppm for an 8 hour time weighted average (TWA) and 15 ppm for a 15 minute short term exposure limit (STEL). Real-time monitors are used by the construction industry as they provide a means of checking that controls are effective. Previous laboratory work at HSL evaluated various commercial detectors potentially suitable as portable monitors and studied the conversion rate of NO to NO2 in air using pure gases (ie NO and air).

Dermatoses professionnelles aux produits phytosanitaires

Les dermatoses professionnelles aux produits phytosanitaires sont essentiellement des dermatites de contact d'irritation, parfois sévères à type de brûlures et plus rarement des dermatites de contact allergiques. Les professions les plus exposées sont de loin les agriculteurs utilisant des phytosanitaires ou travaillant sur des cultures traitées.

SPIROLA: A Solution for More Effective Use of Periodic Spirometry

While mortality rates for most chronic illnesses (heart disease, malignancy, stroke) have declined in the U.S., mortality from chronic obstructive pulmonary disease (COPD) has increased over the past 3 decades. COPD is the fourth-leading cause of death and the second leading cause of disability in the United States. Blue-collar workers have the highest prevalence of chronic obstructive pulmonary disease (COPD) in the country. The main cause of COPD is abnormal inflammatory response of the lung to inhalation of noxious particles and gases, with tobacco smoking being the most prevalent risk factor. Most cases of obstructive or restrictive respiratory diseases are preventable.

Comparison of risks from carbon dioxide and natural gas pipelines

Carbon capture and storage (CCS) is likely to form a significant part of the UK's strategy for achieving its Kyoto targets for CO2 emission reduction. CO2 is not currently regulated as a dangerous fluid under the Pipeline Safety Regulations (PSR) so further investigation is required to determine if it should be re-classified.

Le formaldéhyde provoque également la leucémie

Le formaldéhyde, un cancérogène présent dans de nombreux secteurs professionnels, provoquerait un risque accru de leucémie, selon l’avis d’experts remis en octobre lors d’une réunion du Centre international de recherche sur le cancer (CIRC). Le formaldéhyde est reconnu comme cancérogène certain pour l’homme (groupe 1) mais jusqu’alors surtout associé au cancer nasopharyngien et au cancer des sinus.

Jumelage des cas de mésothéliome et d'amiantose reconnus comme maladies professionnelles pulmonaires aux nouveaux cas de cancer et aux hospitalisations avec amiantose

Cette recherche s'inscrit dans le Programme de développement de la surveillance et des connaissances sur les maladies de l'amiante en lien avec le plan d'action gouvernemental d'utilisation accrue de l'amiante au Québec. Elle vise le jumelage des cas de mésothéliome de la plèvre et d'amiantose reconnus comme des maladies professionnelles pulmonaires par le Comité spécial des maladies professionnelles pulmonaires (CSMPP), aussi appelé Comité spécial des présidents, entre 1975 et 2003, aux nouveaux cas de cancer inscrits au Fichier des tumeurs du Québec (FiTQ) entre 1975 et 2002 et aux nouvelles hospitalisations avec un diagnostic d'amiantose enregistrées dans le système Med-Écho entre 1988 et 2003.

Coal's Assault on Human Health

Physicians for Social Responsibility has released a groundbreaking medical report, “Coal's Assault on Human Health,” which takes a new look at the devastating impacts of coal on the human body. Coal combustion releases mercury, particulate matter, nitrogen oxides, sulfur dioxide, and dozens of other substances known to be hazardous to human health. This report looks at the cumulative harm inflicted by those pollutants on three major body organ systems: the respiratory system, the cardiovascular system, and the nervous system. The report also considers coal's contribution to global warming, and the health implications of global warming.
