Metal-enriched nanoparticles and black carbon: A perspective from the Brazil railway system air pollution

A health perspective of indoor air pollution.

Pnm-9: Association between Air Pollution and Reproductive System Functions

Background The highly sensitive period of preimplantation development represents that embryo is very vulnerable to exogenous agents. Many of the developmental abnormalities may arise from the inevitable maternal periconceptional exposures to toxic substances in the environment which may threaten reproductive capability and pregnancy outcomes. In this article, an overview of the association betw...

The Ergative System in Balochi from a Typological Perspective

For the Western Iranian languages the transition from the Old Iranian to the Middle-Iranian period is characterised by – among other things – the loss of word-final syllables. This loss had a far-reaching impact on the nominal and verbal systems since it caused the loss of categories which had been expressed by suffixes. The consequences include the emergence of the so-called ergative system. ...

Air pollution and the respiratory system.

Over the past 250 years-since the Industrial Revolution accelerated the process of pollutant emission, which, until then, had been limited to the domestic use of fuels (mineral and vegetal) and intermittent volcanic emissions-air pollution has been present in various scenarios. Today, approximately 50% of the people in the world live in cities and urban areas and are exposed to progressively hi...

Impact of California’s air pollution laws on black carbon and their implications for direct radiative forcing

We examine the temporal and the spatial trends in the concentrations of black carbon (BC) e recorded by the IMPROVE monitoring network for the past 20 years e in California. Annual average BC concentrations in California have decreased by about 50% from 0.46 mg m 3 in 1989 to 0.24 m gm 3 in 2008 compared to the corresponding reductions in diesel BC emissions (also about 50%) from a peak of 0.01...
