Aerozagađenje predstavlja koncentraciju štetnih materija preko tolerantne granice (maksimalno dozvoljene koncentracije – MDK), međutim, ova će koncentracija ovisiti ne samo o intenzitetu izvora zagađivanja, nego i od lokalnih uslova u pogledu zračnih strujanja, padavina, konfiguracije terena itd. Djelovanje aerozagađenja na stanovništvo može biti direktno indirektno. oštećuje pogoršava zdravlje...

BACKGROUND Cross-sectional studies suggest an association between exposure to ambient air pollution and atherosclerosis. We investigated the association between outdoor air quality and progression of subclinical atherosclerosis (common carotid artery intima-media thickness, CIMT). METHODOLOGY/PRINCIPAL FINDINGS We examined data from five double-blind randomized trials that assessed effects of...

the equivalent noise level in large cities has been growing due to the population growth, uncontrolled production of cars, and the existence of worn out cars. on the other hand, heavy traffic has increased the amount of noise problems for residents of medical and educational centers, research institutes and residential area (or sensitive centers to noise) built in highway bounds and it has also...

Title of thesis: FIELD EVALUATION OF HYDROLOGIC AND WATER QUALITY BENEFITS OF GRASS SWALES FOR MANAGING HIGHWAY RUNOFF James Howard Stagge, Master of Science, 2006 Thesis directed by: Professor Allen P. Davis Department of Civil and Environmental Engineering Due to growing awareness of non-point source pollution treatment, the performance of grass swales as a highway runoff treatment and the ef...

This paper presents the results obtained in a study of environmental noise pollution in Alexandria city. Alexandria is a coastal city. It is the second largest city in Egypt. Thirty seven sampling sites were selected to measure the noise level at three main streets in the city (Elgish Street, Horreya Avenue and Circular Highway). The minimum noise levels recoded at Elgish Street, Horreya Avenue...

This study aimed to investigate the relative performance of two models (negative binomial (NB) model and two-component finite mixture of negative binomial models (FMNB-2)) in terms of developing crash modification factors (CMFs). Crash data on rural multilane divided highways in California and Texas were modeled with the two models, and crash modification functions (CMFunctions) were derived. T...

BACKGROUND The Democratic National Convention (DNC) in Boston, Massachusetts in 2004 provided an opportunity to evaluate the impacts of a localized and short-term but potentially significant change in traffic patterns on air quality, and to determine the optimal monitoring approach to address events of this nature. It was anticipated that the road closures associated with the DNC would both inf...
