Abstract The environmental consequences and the epidemiologic results of noise pollution have chronic effects and lead to widespread complications in the long run. Thus it might receive less attention by pollution monitoring and control systems when compared with other environmental pollutants. The city of Mashhad is Iran’s second largest metropolitan city and it is one of the biggest world religious cities in the world. Each year it becomes one of the main destinations for travel for tourists and pilgrims in Iran and abroad in the holidays of the beginning of the year and the summer. In this research study the distribution of sound pollutants in the streets and sidewalks leading to the Holy shrine of Imam Reza is investigated. Field measurements were carried out by noise level meters and on longitudinal and transverse points of the sidewalk of the streets leading to the Holy Shrine. All of the measurements and recordings were done during the peak of morning crowd (AM 10-12) and evening crowd (PM 4-6) and on both of the sidewalks of each street. The study showed that the pollution in all of the studied streets in the evening time span (PM 4-6) has the maximum level of noise. Among all of the studied streets, Tabarsi street has the most amount of noise pollution with a mean of 78 dB(A) for the mean intensity for each point and Imam Reza street has the minimum amount of pollution with a mean of 72.75 dB(A). The investigations showed that, from the temporal perspective, the noise pollution peaks in the evening, when weather conditions are most favorable for visiting the area. From the spatial perspective, the most intensive noise pollution was observed in the areas with residential and accommodation land use, which have the highest number of arterial routes towards the shrine.

This study is an approach to assign the land area of  Kirkuk city [ a city located in the northern of Iraq, 236 kilometers north of  Baghdad  and 83 kilometers  south of  Erbil [ Climatic atlas of  Iraq, 1941-1970  ]  into different  multi zones by using Satellite image and Arc Map10.3,  zones of different traffic noise pollutions. Land zonings process like what achieved in this paper will help and of it’s of a high interest point for the future of Kirkuk city especially urban planning and economic issues of the city. Also, it may be considered as a reference in solving the traffic jam problems in the city. Transportations and sounds of horn of vehicles are the major sources of traffic noise pollutions .Vehicular traffic noise problems are contributed by various types of vehicles such as heavy and medium trucks or buses or automobiles. During this study, six major regions within the city were selected (Governorate region, Baghdad road, Al Wasti, Al Askary, Al Nasir and North garage). A survey for all those six regions were taken place  and noise measurements  were captured at points  or  near to the  intersections  for a duration of three different periods days per a week  [  Sunday 3rd , Monday 4th , and  Tuesday 5th] of January 2016. The results showed  a  high level of noise pollution and super passing on many occasions to the prescribed levels by Central Pollution Control Board (CPCB) , maximum level noise pollution  value was 94.6 dB(A) in AlWasti region near to the road that leading to Kirkuk university , while minimum level noise pollution  value was 48 dB(A) in AlNasir region. As a result, a noise map zoning was prepared for Kirkuk City for top peak working three days. The prepared noise distribution map will help and could be used as a considerable point for the future during designing projects related to transportations. Also in another hand, the map reflected indirectly the amount of regional air pollutions. High distributed noise pollution zones means a zone of a high air pollutions levels specially Cox and Nox gaseous pollutions.

Traffic noise barriers are one of the most important ways of environmental noise pollution control. Profiled barriers are one of the most successful noise control screens. A simple mathematical model representation of the zones behind rigid and absorbent barriers with the highest insertion loss using the destructive effect of the indirect path via barrier image is introduced. The results are compared with the results of a verified two-dimensional (2D) BEM in a wide field behind those barriers. Field measurements for the model near a highway in a megacity were also tested. A very good agreement between the results has been achieved. In this method, effective height is used for any different profile barrier. Since the highway dominant noise frequency was found to be at 125 Hz 1/3-octave band center frequency, the presented model in this study showed that the best place for installing a T-shaped barrier is 10.5[Formula: see text]m from the target receiver. The introduced model is very simple and fast and could be used for choosing the best location of profiled barriers to achieve the highest performance with no additional cost.

The transportation policies focusing on minimizing the environmental impact aim at an improved quality of life and health of the population, the urban one in particular. Noise pollution is one of the biggest problems associated with the European urban environment at the present moment, mainly because of the ever-increasing road traffic. SUNET system (System for Urban Noise and Eco-Traffic) was designed to improve the management of the noise pollution in Cluj-Napoca and to provide up-to-date public data on a user-friendly interface. The implementation of the application over the entire municipality is highly advantageous as it creates a link between the town’s administration (the local authorities, the City Hall of Cluj-Napoca) and the user (the citizens) through this system which is dynamic, modern and compliant with the European regulations. The graphic interface uses the HTML (HyperText Markup Language) code, while the database is set up in an SQL (Structured Query Language) format and contains information about the characteristics of the system and users alike, all organized in specific tables. The need for an online urban noise pollution monitoring system, such as the SUNET one, appears to allow the provision of fairly realistic and up-to-date information and encourage the community to actively assist in the application of proper action plans and the decision-making process when it comes to the population’s exposure to high levels of noise pollution.

Dynamic Phenomena

In this paper, we propose a decentralized semantic reasoning approach for modeling vague spatial objects from sensor network data describing vague shape phenomena, such as forest fire, air pollution, traffic noise, etc. This is a challenging problem as it necessitates appropriate aggregation of sensor data and their update with respect to the evolution of the state of the phenomena to be represented. Sensor data are generally poorly provided in terms of semantic information. Hence, the proposed approach starts with building a knowledge base integrating sensor and domain ontologies and then uses fuzzy rules to extract three-valued spatial qualitative information expressing the relative position of each sensor with respect to the monitored phenomenon’s extent. The observed phenomena are modeled using a fuzzy-crisp type spatial object made of a kernel and a conjecture part, which is a more realistic spatial representation for such vague shape environmental phenomena. The second step of our approach uses decentralized computing techniques to infer boundary detection and vertices for the kernel and conjecture parts of spatial objects using fuzzy IF-THEN rules. Finally, we present a case study for urban noise pollution monitoring by a sensor network, which is implemented in Netlogo to illustrate the validity of the proposed approach.

Abstract In today’s era, vehicular noise pollution has been identified as a serious danger that influence the attribute of the urban regions. To identify the influence of noise effects, noise maps are very useful. A noise mapping study has been carried out to study the propagation of urban road traffic noise in the areas along with field measurements. The computer simulation model (Sound- PLAN software) is used to developed noise maps. In developing nations like India, traffic composition is heterogeneous. These traffic compositions contain vehicles, which have different sizes, speeds variations and operating systems. Because of fluctuating speeds, deficiency of lane disciplines, and non-authorized parking on main road lanes, honking events becomes inevitable, which changes and affects the urban soundscape of nations like India. Due to horn events (heterogeneous traffic condition), noise level (LAeq) increase by 0.5–8 dB (A) as compared to homogeneous traffic conditions.

The present review summarizes the literature data regarding the application of Triticum aestivum assay as an alternative method for toxicity assessment of environmental pollutants or potential therapeutic agents. Plant bioassays present several advantages among other biological assays (simplicity, low cost, rapid test activation, a wide array of assessment endpoints). They present a good correlation with animal and human cells models, and are a reliable tool for genotoxicity assessment. Furthermore, in the context of toxicology guidelines that promote the substitution of assays using animal models with other bioassays, genotoxicity assays using higher plants models have gained in popularity. The present review focuses on three major aspects regarding Triticum aestivum assay - its utility in environmental pollution monitoring, its application in genotoxicity assessment studies, and its application in phytotoxicity evaluation of nanomaterials.   ********* In press - Online First.
