The creation of pollution mapping and measurement of ambient concentration of sulfur dioxide and nitrogen dioxide with passive sampler
نویسنده
چکیده
BACKGROUND Measurements of nitrogen and sulfur dioxide using passive sampler over 12 months in Samsun, Turkey, are compared with SO2 and NO2 concentrations obtained from a co-located chemiluminescence analyzer. The concentrations of Sulfur and nitrogen dioxide in the ambient air during the period from November 2009 to September 2010 are analyzed. RESULTS The highest value for annual NO2 and SO2 averages of passive sampler was 29.65 μg/m(3) and 21.01 μg/m(3) for exposures of 2-weeks at an industrial site. The maximum monthly concentration for SO2 was observed at the 10(th) measurement station with 44.19 μg/m(3) for August. The maximum monthly concentration for NO2 was observed on the 3(rd) measurement station with 42.83 μg/m(3) for November. A negative correlation between nitrogen dioxide concentrations and temperature (R(2) = -0.5489) was estimated. A positive correlation between nitrogen dioxide measurement with passive sampler and continuous measurement (R(2) = 0.6571) was estimated.

Background: Adverse pregnancy outcomes (low birth weight, prematurity and intrauterine growth retardation) are associated with exposure to urban air pollution. Experimental data have also shown that such exposure elicits adverse reproductive outcomes. We examined association between spontaneous abortion of the first trimester of pregnancy and ambient concentrations of Ozone, Nirogen Dioxide and...
متن کاملMeasurement of Air Pollution in Kuwait City Using Passive Samplers
Measurements of gaseous SO2, NO, NO2, H2S, O3, NH3 and VOCs, in Kuwait city using IVL passive sampler technology, were obtained on monthly basis during the period from March 2011 to February 2012 at 10 locations. The results of this study reveal that those compounds had low concentrations compared to Kuwait Environment Public Authority standards for residential areas. It is found that nitrogen ...

Two experimental monitoring campaigns were carried out in 2012 to investigate the air quality in the port of Naples, the most important in southern Italy for traffic of passengers and one of the most important for goods. Therefore, it represents an important air pollution source located close to the city of Naples. The concentrations of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and BTEX (be...
متن کاملModeling of sulfur dioxide emissions in Ahvaz City, southwest of Iran during 2013
Sulfur dioxide has two important sources in the atmosphere and this is why most of scientists believe in a geographic split in the globe. Power plants, major emitter of SO2, are located in north hemisphere such as in Russia, China, Canada and the USA. In south hemisphere, phytoplankton produces a massive amount of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS). Then these types of reduced...
