Introduction Lake Tahoe resides in a high elevation basin separated from the Sacramento Valley by the dominant Sierra Nevada divide along the Crystal Range. Lower ridges of the Carson Range to the east separate the lake from the Great Basin. These physical attributes define atmospheric processes in the Tahoe basin as much as define hydrological processes. The presence of the cold lake at the bo...

We present a study of the potential export pathways of middle-lived pollutants from the Iberian Peninsula using an advanced 3-D Lagrangian atmospheric transport model (FLEXPART). A period of five years, from 2000 to 2004, was analyzed. Results confirm that the Mediterranean Sea and Central Asia are the dominant sinks of the air originated in the Iberian Peninsula in the range of 3 to 10 days of...

Global contamination and toxic effects of persistent organic pollutants (POPs) have been an emerging environmental issue and have received considerable attention during the past four decades. Although the extent of contamination by POPs has been dominant in industrialized nations, an increasing number of recent investigations have highlighted the role of the Asia-Pacific region as a potential s...

This review presents a brief overview of the health effects and exposures of two criteria pollutants--ozone and particulate matter--and two toxic air pollutants--benzene and formaldehyde. These pollutants were selected from the six criteria pollutants and from the 189 toxic air pollutants on the basis of their prevalence in the United States, their physicochemical behavior, and the magnitude of...

Abstract Microplastic pollutes water, land, air, and groundwater environments not only visually but also ecologically for plants, animals, humans. has been reported to act as vectors by sorbing pollutants contributing the bioaccumulation of pollutants, particularly in marine ecosystems, organisms, subsequently food webs. The inevitable exposure microplastic humans emphasises need review potenti...

When faced with limited resources, juvenile salmonid fish form dominance hierarchies that result in social stress for socially subordinate individuals. Social stress, in turn, can have consequences for the ability of the fish to respond to additional stressors such as pathogens or exposure to pollutants. In the present study, the possibility that social stress affects the ability of rainbow tro...

Cold fronts frequently intrude China in winter, causing air pollution episodes downwind regions. Fine particulate matter (PM2.5) has been used as a major proxy of to examine the impacts cold fronts. Compared particles, gaseous pollutants can cause comparable or even higher levels short-term health risks. In this study, pollution-to-risk model was systematically evaluate on combined risks mixtur...

Acetaldehyde is a typical toxic substance of the petrochemical industry. Dissolved organic carbon (DOC) plays an important role in wastewater treatment. Therefore, molecular weight, hydrophilicity, and chemical composition DOC acetaldehyde were evaluated. First, weight (MW) distribution was investigated; results showed that mainly composed components with MW less than 1 kDa, possessed higher pr...
