Statistical data analysis on toxicity for air pollution problems is studied for the atmosphere with the various pollutant’s observations. In this paper Kriging techniques are explained for pollutant concentration, also forecast by Kriging methods. Approximate function called as system function is obtained by these techniques. An approach is mentioned for calculating weights for the given data. ...
Several studies utilizing adult subjects have indicated that static stretching may reduce subsequent strength and power production, possibly for as long as an hour following the stretch. This observation has not been evaluated in children, nor in athletes accustomed to performing static stretches during strength/ power type training sessions. The purpose of this investigation was to determine i...
Asthma is common in children worldwide, although its prevalence varies substantially by location. The prevalence of wheeze over a 12-month period ranged from 2.1% to 32.2% in the older age group (13–14 years) and 4.1% to 32.1% in the younger age group (6–7 years) [1]. There is a positive association between current symptoms of asthma in younger and older children with gross national income [2],...
We examined the utility of a newly developed perceived air pollution (PAP) scale and of a modeled air pollution (MAP) scale derived from it for predicting previously observed birth outcomes of pregnant women enrolled following September 11, 2001. Women reported their home and work locations in the four weeks after September 11, 2001 and the PAP at each site on a four-point scale designed for th...
OBJECTIVE To evaluate indoor air pollution in hospitality venues in Argentina. MATERIAL AND METHODS PM₂.₅ levels were measured in a convenience sample of venues in 15 cities with different legislative contexts following a protocol developed by Roswell Park Cancer Institute. RESULTS 554 samples were collected. Across all 5 smoke free cities the mean PM₂.₅ level was lower during daytime vs. e...
BACKGROUND Few studies have been conducted to investigate the impact of extreme cold events on mortality in subtropical regions. OBJECTIVE In the present study we aimed to investigate the effects of the 2008 cold spell on mortality and the possibility of mortality displacement in three subtropical cities in China. METHODS Daily mortality, air pollution, and weather data were collected from ...
BACKGROUND Both outdoor air pollution and extreme temperature have been associated with daily mortality; however, the effect of their interaction is not known. METHODS This time-series analysis examined the effect of the interaction between outdoor air pollutants and extreme temperature on daily mortality in Shanghai, China. A generalized additive model (GAM) with penalized splines was used t...
Five cases of air embolism in ventilated very low birthweight infants are reported. In all cases the outcome was fatal with the babies dying at about 15 hours of age.
Health risks from poor malaria control, unsafe water, and indoor air pollution are responsible for an important share of the global disease burden-and they can be addressed by efficacious household health technologies that have existed for decades. However, coverage rates of these products among populations at risk remain disappointingly low. We conducted a review of the medical and public heal...
While enforceable National Environmental Quality Standards for pollutants exist in Pakistan, ambient air quality guidelines have never been established. However, there is no reliable epidemiological/toxicological monitoring system in place in Pakistan to provide a basis for establishing guidelines for various air pollutants. This paper reviews the World Health Organization air quality guideline...
