Agriculture is responsible for 98% of atmospheric ammonia (NH3) in Ireland, which pigs and poultry produce 7%; with laying hens specifically contributing 0.6%. Though a small proportion the national NH3 total emissions, ecological impacts on sensitive sites attributed to hen farms can be substantial. emission monitoring was conducted Spring (February March) Summer (July August) 2016 account sea...

Dispersion modeling approach was applied for the determination of SO2 and NO2 pollution in the ambient air. The model performance has been evaluated by comparing the measured and predicted concentrations of SO2 and NO2. This has been tested to measure the air quality and predicted incremental value of pollutant’s concentrations by using the data avail...

The paper presents a new web interface to the atmospheric dispersion model HARP (HAzardous Radioactivity Propagation) which is a segmented Gaussian plume model certified for the emergency management use in the Czech Republic. Up to now, the model was available only as a desktop application. The new web-based user interface should bring the basic functionality of the model to the web environment...

The stochastic trajectory-based (Lagrangian) approach has gained increasing importance and sophistication in atmospheric transport and dispersion modelling over the last few decades. State-of-the-art Lagrangian particle dispersion model (LPDMs) are used to compute trajectories of a large number of ‘marked’ particles and numerically simulate the dispersion of a pollutant (passive tracer) in the ...

Mathematical air pollution modeling represents an essential tool to control and predict atmospheric pollution. In this paper, a multiple cell model for the three-dimensional simulation of pollutants (SO2, CO, NOx, and TH) dispersion from a network of industrial stacks is presented. The model verification was conducted by checking the simulation results for a single stack against experimental da...

This paper details a number of existing formulations used in Gaussian models in a clear and usable way, and provides a comparison within a single framework—the Gaussian plume and puff models of the air quality modeling system Polyphemus. The emphasis is made on the comparison between (1) the parameterizations to compute the standard deviations and (2) the plume rise schemes. The Gaussian formul...

Atrazine, a herbicide widely used in corn production, is frequently detected as pesticide in water resources. In this research, four agricultural fields with a long history of atrazine application in Shiraz and its vicinity in Fars province of Iran, have been studied to determine the fate of atrazine through the passage of time. These four farms were cultivated under a crop rotation (corn-wheat...
