Recent results suggest that adverse health effects of air pollution exist at levels of pollutants around or even below air quality standards set by national and international institutions. Furthermore, there are indications that air pollution effects on health may be partly determined by specific mixtures of air pollutants and may be altered by other environmental, behavioral, and social patter...

OBJECTIVE To determine whether there was excess ill health in people living near a coking works, and if so whether it was related to exposure to coking works' emissions. DESIGN Populations varying in proximity to the coking works were compared with control populations. Health data were correlated with available environmental data. METHODS Analysis of routinely collected mortality, cancer re...

The general morbidity is being influenced to a great extent by air way diseases. Since their incidence and prevalence have been increasing, the identification of causal factors is of importance for preventive strategies. Primary irritative, gaseous (like sulfur dioxide (SOz)) as well as particulate pollutants (like TSP) can be regarded as causal constituents. Using the opportunity of changing l...

Time-resolved single-particle measurements were conducted during Chinese New Year in Nanning, China. Firework displays resulted in a burst of SO2, coarse mode, and accumulation mode (100-500nm) particles. Through single particle mass spectrometry analysis, five different types of particles (fireworks-metal, ash, dust, organic carbon-sulfate (OC-sulfate), biomass burning) with different size dis...

A study was conducted to determine the effect of carbon monoxide (CO), nitroxide (NOx) and sulfur dioxide (SO2) on ROS production, photosynthesis and ascorbate-glutathione pathway in strawberry plants. The results showed that both singlet oxygen (O2(-1)) and hydrogen peroxide (H2O2) content increased in CO, NOx and SO2 treated strawberry leaves. A drastic reduction of primary metabolism of plan...

During the last decades special attention of scientists has been focused on environmental pollution intensity and a great number of the so-called outdoor allergens (SO2, NO2, phenol, combustion gases, etc.) as well as on their increasing effect of formation of allergic diseases. Children's population is most sensitive to the influence of unfavorable environmental factors. This is associated wit...

Dr. Yusuf G (Debo) Adewuyi is a Professor of Chemical, Biological and Bioengineering Department at North Carolina A&T State University, where his research is in sustainable production of energy & chemical products; synthesis of nanoscale materials for energy and environmental applications; sonochemistry, cavitation and advanced oxidation processes for pollution treatment; liquid-phase chemistry...

We characterize a representative haze event from a series of periodic particulate matter (PM) episodes that occurred in Shanghai during winter 2014. Particle size distribution, hygroscopicity, effective density and effective density single particle mass spectrometry were measured determined online, along with offline analysis of water-soluble inorganic ions and single particle mass spectrometry...
