Environmental concerns often figure prominently in opinion polls. But do election outcomes actually affect the environment? I test the influence of the party in power on urban air pollution in 13 Canadian cities. The government’s political stripe is not reliably associated with positive or negative effects on air pollution. Provincial parties on both the right and the left are associated with e...

Particulate pollution has important consequences for human health, and is an issue of global concern. Outdoor air pollution has become a cause for alarm in India in particular because recent data suggest that ambient pollution levels in Indian cities are some of the highest in the world. We study the number of particles between 0.5μm and 2.5μm indoors while using affordable air purifiers in the...

Ships transport about 80 percent of world trade and transfer approximately three to five billion tons of ballast water internationally every year. Due to the likely presence of pollutants, the ballast water discharged by ships can have negative effects on aquatic ecosystems. This study was conducted on 10 ships that entered the Bushehr port to determine the effectiveness of the ballast water ex...

we proposed to use artificial channels in laboratory assays to expose periphyton to substancesreleased in rural environments in order to test the following hypotheses 1) a high concentration of humicsubstances decreases the biofilm biomass and alters its metabolism; 2) periphyton biomass and metabolism increase in response to nutrient addition in spite of the previous high nutrient concentratio...

OBJECTIVES Air pollution exposure induces cardiovascular effects, possibly via systemic inflammation and coagulation misbalance. Genetic variation may determine individual susceptibility. Our aim was to investigate effect modification by inflammation (Interleukin6 (IL6), tumour necrosis factor-α (TNF-α)) and coagulation (fibrinogen Bβ, plasminogen activator inhibitor-1 (PAI-1)) gene variants on...

An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as either primary or secondary. Air pollution, both indoors and outdoors, is a major environmental health problem affecting everyone in develo...

air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. it has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution.according to the world health organization, six major air pollutants include particle pollution, ground?level ozone, carbon mono...
