the aim of this study is to determine the area affected by dust storms in different wind speeds using satelliteimages. in the first step, windy conditions of the sistan plain were analyzed using wind statistics data. next, fivestormy days of zabol city, indicating different wind speeds and horizontal visibilities during those storms, wereselected. then, high temporal resolution modis data was u...

The nature of mutagenic burden due to occupational exposure to tobacco flakes and dust was determined among 20 female tobacco processors (TP) and 20 matched controls (C) by testing urinary mutagenicity in the Ames assay. In addition, urinary cotinine was estimated as a marker of tobacco absorption. Workers and controls were sub-divided into those with no tobacco habit (NH) and those habituated ...

Background and aims: India has a high burden of tobacco usage and its related morbidity and mortality. Almost 30% of the above 15 years of age of the Indian population use some forms of tobacco. Men usually use smoked tobacco, while women more likely use smokeless (chewed) tobacco. Tobacco usage has been identified as a risk factor for non-communicable diseases (NCDs) among slum dwellers in urb...

background: iran is one of the countries that has ratified the world health organization framework convention of tobacco control (who-fctc), and has implemented a series of tobacco control interventions including the comprehensive tobacco control law. enforcement of this legislation and assessment of its outcome requires a dedicated evaluation system. this study aimed to develop a generic model...

Blood lead levels (BLLs) have substantially decreased in recent decades in children in France. However, further reducing exposure is a public health goal because there is no clear toxicological threshold. The identification of the environmental determinants of BLLs as well as risk factors associated with high BLLs is important to update prevention strategies. We aimed to estimate the contributi...

Massive periretinal proliferation (MPP), a serious complication of retinal detachment, is caused by proliferation and fibrous metaplasia of cells mostly deriving from retinal pigment epithelium and retinal glial cells. Contracting fibrous membranes in the vitreous, and on and also under the retina, cause the intraocular changes of MPP. Early signs such as increased 'tobacco dust', pigmented and...

OBJECTIVES To examine (1) whether dust and surfaces in households of smokers are contaminated with environmental tobacco smoke (ETS); (2) whether smoking parents can protect their infants by smoking outside and away from the infant; and (3) whether contaminated dust, surfaces, and air contribute to ETS exposure in infants. DESIGN Quasi-experiment comparing three types of households with infan...

introduction thermal infrared integrated dust index (tiidi) is one of indices that is presented in this direction. the index operates based on four brightness temperature difference including wavelengths 3.7, 8.6, 11 and 12 micrometer. according to the studies, btd (bt12-bt11) is used for cloud detection. btd (bt8.6-bt11) is the index for separation for dust from sandy surface and btd (bt3.7-bt...

Enfi eld et al 3 at the University of Virginia also recently reviewed outcomes in 30 patients at multiple centers who underwent lung transplantation for severe CWP since 1987, using the database of the United Network for Organ Sharing. In the University of Virginia analysis, after account ing for age, lung allocation score, and type of transplant, 1-year survival after transplantation appeared ...
