abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Numerous studies have linked ambient air pollution and adverse health outcomes. Most studies of this nature relate outdoor pollution levels measured at a few monitoring stations with counts of health outcomes. Recently, computational methods have been developed to model the distribution of personal exposures, rather than ambient concentration, and then relate the exposure distribution to the he...
analysis of multilevel analytic studies with applications to a study of air pollution. cumulative ambient concentrations of air pollutants: description and precision of methods used for an epi-demiologic study. association between air pollution and mortality in six U. Association between lifetime ambient ozone exposure and pulmonary function in college freshman-results of a pilot study. Kunzli ...
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
BACKGROUND Heat and air pollution are both associated with increases in mortality. However, the interactive effect of temperature and air pollution on mortality remains unsettled. Similarly, the relationship between air pollution, air temperature, and social deprivation has never been explored. METHODS We used daily mortality data from 2004 to 2009, daily mean temperature variables and relati...
Wang et al. (2014) investigated the relationship between ambient air pollution and depressive symptoms in a prospective study of elderly people over age 65 years. We are very surprised that the authors found no association between ambient air pollution and depressive symptoms, which is inconsistent with most previous studies (e.g., Banerjee et al. 2012; Calderón-Garcidueñas et al. 2014). A stud...
OBJECTIVE We sought to assess the effect of long-term exposure to ambient air pollution on the prevalence of self-reported health outcomes in Australian women. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS The geocoded residential addresses of 26,991 women across 3 age cohorts in the Australian Longitudinal Study on Women's Health between 2006 and 2011 were linked to nitrogen dioxi...
to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...
BACKGROUND The chronic health effects from exposure to ambient air pollution are still unclear. This study primarily aims to examine the relationship between long-term exposure to ambient air pollution and respiratory morbidities in Chinese children. METHODS A cross-sectional study was conducted among 2,203 school children aged 8-10 in three districts with different air pollution levels in Ho...
background : health professionals face the adverse health effects of climate change and air pollution in their practices. this review underscores the effects of these environmental factors on maternal and children’s health, as the most vulnerable groups to climate change and air pollution. methods : we reviewed electronic databases for a search of the literature to find relevant studies publish...
