background & purpose: air pollution has been known as one of the most effective factors on cardiovascular, pulmonary and infectious diseases. this study aims to determine the relation between mortality rate and air pollution in mashhad during 2007-2009. materials & methods: data of air pollution, mortality rate and geographic factors were collected during 2007-2009 and analyzed. mortality rate,...

Parasitoids are important organisms in the regulation of insect herbivores in natural, urban, and agricultural ecosystems. The impact of pollutants acting on parasitoids has not been extensively reviewed. This prompted us to propose a falsifiable null hypothesis (pollutants have no effects on parasitoids) and two alternative hypotheses (pollution negatively or positively affects parasitoids) to...

Pollutants, brought into a swimming pool by bathers, will react with chlorine to form disinfection by-products (DBPs). Some of these DBPs are found to be respiratory and ocular irritant and might be associated with asthma, or might even be carcinogenic. As DBPs in swimming pools are formed from bather-shed-pollutants, a reduction of these pollutants will lead to a reduction of DBPs. Until now, ...

Developmental toxicity caused by exposure to a mixture of environmental pollutants has become a major health concern. Human-made chemicals, including xenoestrogens, pesticides and heavy metals, as well as unhealthy lifestyle behaviours, mainly tobacco smoking, alcohol consumption and medical drug abuse, are major factors that adversely influence prenatal development and increase susceptibility ...

THE ENVIRONMENT AND THE LUNG 27S daily symptoms to daily levels of air pollutants, and 2) to act as a surveillance tool for acute respiratory illness (AR!). The ARIs were detected with the aid of the daily diaries and when a child was detected with an AR! he/she was called to the clinic for direct observation. If it was a true AR!, pulmonary function tests were conducted twice during the sympto...

OBJECTIVE A growing body of evidence suggests that environmental pollutants, such as heavy metals, persistent organic pollutants and plasticizers play an important role in the development of chronic diseases. Most epidemiologic studies have examined environmental pollutants individually, but in real life, we are exposed to multi-pollutants and pollution mixtures, not single pollutants. Although...
