BACKGROUND Mild hyperhomocysteinemia is independently associated with an increased risk of cardiovascular disease. Air pollution exposure induces short-term inflammatory changes that may determine hyperhomocysteinemia, particularly in the presence of a preexisting proinflammatory status such as that found in cigarette smokers. OBJECTIVE We examined the relation of air pollution levels with fa...

The study evaluated eight heavy metals content and soil pollution from agricultural soils in northern China. Multivariate and geostatistical analysis approaches were used to determine the anthropogenic and natural contribution of soil heavy metal concentrations. Single pollution index and integrated pollution index could be used to evaluate soil heavy metal risk. The results show that the first...

Background & Aims of the Study: In this research, Long-Term Hydrologic Impact Assessment model is selected for simulation of runoff and NPS pollution. The aim of this study is modeling of non-point source pollution by L-THIA model in Zayandehrood watershed in 2015. Materials & Methods: In this study, analytical survey and investigation of references in the context of libr...

Non-point source (NPS) pollution contributes greatly to the contamination of surface water quality and has aroused widespread concerns. NPS pollution is influenced by a multitude of site-related factors whose effects are complicated. We estimated NPS pollution with a soil and water assessment tool (SWAT) model in China’s Fan River watershed. A new method, boosted regression tree (BRT), was prop...

Macroinvertebrates identification and enumeration may be used as a simple and affordable alternative to chemical analysis in water pollution monitoring. However, the ecological responses of various taxa to pollution are poorly known in resources-limited tropical countries. While freshwater macroinvertebrates have been used in the assessment of water quality in Europe and the Americas, investiga...

although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. in any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. in the present study, air pollution tolerance index was calculated for var...

a long-standing debate among the vocabulary researchers is the depth of processing to learn vocabulary. this paper is a quantitative research which considers a revision in the “involvement load hypothesis” proposed by laufer and hulstijn in 2001. it investigates the role of proficiency and evaluation in this hypothesis in order to better reveal its potential contribution to vocabulary learning....
