Pendant Les annees dernieres la Pollution de l, athmosphere des salles d, Operation Par les anesthesiques volatils et Gazeux est bien etu­diee et la consequence Pathologique de cette Pollution est certaine; c, est Poruquois nous som­mes obliges de diminuer cette Pollution et em­pecher de se repandre ces agents dans les salles d, Operation. 

AIMS Episodes of increased air pollution are associated with increases in hospital admissions for cardiovascular disease. Even modest acute phase responses are associated with increased risk of coronary heart disease. The study investigates whether induction of an acute phase response by exposure to air pollution may contribute to cardiovascular pathology. METHODS AND RESULTS A prospective co...

Biomass allocation is an important plant trait that responds plastically to environmental heterogeneities. However, the effects on this trait of pollutants owing to human activities remain largely unknown. In this study, we investigated the response of biomass allocation of Phragmites australis to petroleum pollution by a ¹³CO₂ pulse-labelling technique. Our data show that plant biomass signifi...

Air pollution exposure studies in the past decade have focused on acute (days) or long-term (years) effects. We present an analysis of medium-term (weeks to months) exposure effects of particulate pollution and temperature. We assessed the associations of particulate pollution (black smoke) and temperature with age-standardized daily mortality rates over 17 years in Dublin, Ireland, using a pol...

Economists viewed the world through the eyes of Pigou (1920). Professor A. C. Pigou had argued that in the face of an externality, such as pollution, the appropriate remedy involved imposing a per-unit tax on the emissions from a polluting activity. The tax rate would be set equal to the marginal external social damage caused by the last unit of pollution at the efficient allocation. Faced with...

Programs to reduce tra¢ c congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success, given existing studies of such programs. We conduct the …rst study of Quito, Ecuador’s three-year-old Pico y Placa program and …nd that it has reduced ambient concentrations of carbon monoxide (CO), a pollutant primarily emitted by vehicles, by 9-11% d...

In the present report the changes in mussels Mytilus galloprovincialis protein profile, as a reaction of water pollution, is presented. The antioxidant capacity was determined by the efficacy to scavenge the derived radical in mussel samples using the Trolox Equivalent Antioxidant Capacity (TEAC) assay. The highest percentage of inhibition was estimated in protein mussels from the dirty area (D...

The effect of air pollution on chronic respiratory diseases (CRD) was examined in a study in the New York metropolitan area in 1972. Four study communities, sites A, B, C and D, were selected for the similarity of socioeconomic and demographic characteristics. Historically, these communities represented an increasing gradient of air pollution levels. However, after air quality improvement in th...
