Ever growing populations in cities are associated with a major increase in road vehicles and air pollution. The overall high levels of urban air pollution have been shown to be of a significant risk to city dwellers. However, the impacts of very high but temporally and spatially restricted pollution, and thus exposure, are still poorly understood. Conventional approaches to air quality monitori...

This paper presents a survey of methods of regulations with focus on pollution abatement and of various approaches to the issue of measuring quantities such as the marginal benefit of improved health that are crucial in view of implementing the regulation. Since pollution is a public bad, in general the efficient level of pollution can only be reached by way of some sort of public intervention....

Pollution accidents that occur in surface waters, especially in drinking water source areas, greatly threaten the urban water supply system. During water pollution source localization, there are complicated pollutant spreading conditions and pollutant concentrations vary in a wide range. This paper provides a scalable total solution, investigating a distributed localization method in wireless s...

BACKGROUND Exposure to particulate air pollution is associated with an increased risk of cardiovascular disease. The mechanism by which exposure increases risk is poorly understood but could involve changes in the flow properties of blood. OBJECTIVE The aim of this investigation was to assess the effect, in rats, of intratracheal instillation of particulate air pollution on leukocyte flow pro...

Rachman [(1994). Pollution of the mind. Behaviour Research and Therapy, 32, 311-314] theorized that a subtype of compulsive washing exists which has its compulsions triggered by feelings of internal dirtiness, or 'mental pollution'. Since this construct was proposed, few empirical studies have examined it in relation to obsessive-compulsive contamination fear. This study represents a validation...

Early exposure to environmental toxins like lead, air pollution, and arsenic can have long-lasting and irreversible consequences for children's neurodevelopment, especially in the developing world. Though the number of pollutants increases each year, some neuroscientists are forging partnerships to improve measurement, raise awareness, and promote global health.

Pollution (i.e., sharing corrupted files, or contaminating index information with bogus index records) is a de facto problem in many file sharing Peer-to-Peer (P2P) systems. Since pollution squanders network resources and frustrates users with unprofitable downloads (due to polluted files) and unproductive download requests (due to bogus index records), the future success of file sharing based ...

BACKGROUND Green spaces are reported to improve health status, including beneficial effects on pregnancy outcomes. Despite the suggestions of air pollution-related health benefits of green spaces, there is no available evidence on the impact of greenness on personal exposure to air pollution. OBJECTIVES We investigated the association between surrounding greenness and personal exposure to air...

Abstract. The increasing ozone (O3) pollution and high fraction of secondary organic aerosols (SOA) in fine particle mass has highlighted the importance volatile compounds (VOCs) air control. In this work, four intensive field measurements VOCs during winter 2018 (from 1 December to 17 January 2019), spring (15 April 27 May), summer (17 June 13 July), autumn (22 September November) 2019 were co...

Atmospheric deposition of the major elements was estimated from throughfall and bulk deposition measurements on 13 plots of the Swiss Long-Term Forest Ecosystem Research (LWF) between 1995 and 2001. Independent estimates of the wet and dry deposition of nitrogen (N) and sulfur (S) on these same plots were gained from combined simplified models. The highest deposition fluxes were measured at Nov...
