occupational exposure to welding fumes using different ventilation scenarios
welders may suffer from welding fumes generated during the process if the ventilation systems are improperly applied. the objective of the present work was to study the mitigation of air pollutants at welding stations, using different ventilation scenarios. four air pollutants including iron oxide, respirable dust, ozone, and carbon monoxide were measured during four different ventilation scena...
متن کاملCancer Risk Assessment in Welder’s Under Different Exposure Scenarios
BACKGROUND Welders exposure to nickel and hexavalent chromium in welding fumes is associated with increase of cancer risk in welders. In this study we calculated cancer risk due to exposure to these compounds in welders. METHODS The role of exposure parameters in welders on derived incremental lifetime cancer risk were determined by stochastic modeling of cancer risk. Input parameters were de...
متن کاملPrediction of Climate Change in Western of Iran using Downscaling of HadCM3 Model under Different Scenarios
Abstract Considering that water resources are at risk from climate change, the study of temperature and precipitation changes in the coming years can lead to droughts such as droughts, sudden floods, high evaporation and environmental degradation. To this end, global climate models (GCMs) are designed to assess climate change. The outputs of these models have low spatial accuracy. In order ...
متن کاملAir flow and particle control with different ventilation systems in a classroom.
Most ventilation and air conditioning systems are designed without much concern about how settling particles behave in ventilation air flows. For displacement ventilation systems, designers normally assume that all pollutants follow the buoyant air flow into an upper zone, where they are evacuated. This is, however, not always true. Previous studies show that high concentrations of settling res...
متن کاملAn Analysis of Natural Ventilation Function in Vakil Bazaar
Despite the similar performance of Bazaar1 in different cities of Iran, there are some the skeletal differences between markets in different climates. The Bazaar roof protects customers against natural events in any climate. The ceiling height and the sitting down of the Bazaar`s floor are determined based on the need for air circulation and movement in various climates. Hence, combination of a...
