Photochemical oxidants Cprimarily ozone) a s a i r po l lu tan ts pose a more ser ious problem t o f o r e s t s of t he United S t a t e s than any o ther s ing le a i r po l lu tan t . Temperate and Mediterraean fo r e s t s elsewhere have most l i k e l y been s imi l a r l y impacted and current inves t iga t ions of such e f f e c t s a re being pursued.

This review summarizes major findings over the last decade related to nitrosamines in drinking water, with a particular focus on N-nitrosodimethylamine (NDMA), because it is among the most widely detected nitrosamines in drinking waters. The reaction of inorganic dichloramine with amine precursors is likely the dominant mechanism responsible for NDMA formation in drinking waters. Even when occu...

Initial (IC) and boundary conditions (BC) are required in order to solve the set of stiff differential equations included in air quality models. In this work, the influences of ICeBC are analyzed in the northeastern Iberian Peninsula (NEIP) by applying MM5eEMICAT2000eCMAQ. A multiscale-nested configuration has been used to generate the ICeBC. The wider domain (D1) covers an area of 1392 1104 km...

Background: Studies have reported the beneficial effects of exercise, ozone therapy, and stem cell therapy for the treatment of knee osteoarthritis.  Objectives: To reduce the duration of the treatment, we decided to investigate the synergistic effects of Endurance Training (ET), ozone therapy, and mesenchymal stem cell (MSCs) therapy separately or in combination on the cannabinoid receptors 1...

Sporadic efforts have been introduced to control emissions in Delhi, but the air quality has declined further due rapid development of different sectors. In this study, impact various mitigation scenarios on for PM10, ozone, and its precursors are studied using a chemical transport model, namely WRF-Chem. The Emission Database Global Atmospheric Research emission inventory was modified into WRF...

[1] The kinetics of ozone (O3) chemistry and its two main precursors, nitrogen oxides (NOx) and volatile organic compounds (VOC), represents an important field of uncertainty in atmospheric chemistry and photochemical modeling. This uncertainty affects the design of control strategies to reduce tropospheric O3 production. The effect of controlling ozone precursors on sensitivity regimes was eva...

We examine the climate effects of the emissions of near-term climate forcers (NTCFs) from 4 continental regions (East Asia, Europe, North America and South Asia) using results from the Task Force on Hemispheric Transport of Air Pollution Source-Receptor global chemical transport model simulations. We address 3 aerosol species (sulphate, particulate organic matter and black carbon) and 4 ozone p...

This study presents a 2014 high-resolution spatially disaggregated emission inventory (0.025° × 0.025° horizontal resolution), of the main activities in the energy sector in Argentina. The sub-sectors considered are public generation of electricity, oil refineries, cement production, transport (maritime, air, rail and road), residential and commercial. The following pollutants were included: gr...
