Impact of Air Quality on Human Health In The Vicinity of Construction Sites i...IJERA Editor
Ā
Construction sites are important source of air pollution emitting pollutants like PM10, etc. which adversely affect human health especially the respiratory system. The present study aims at monitoring of PM10, health condition of workers, evaluation of API (Air Pollution Index) and development of correlation between API and human health in the vicinity of construction sites. In the present study relevant literature review has also been carried out to study and analyze the impact of air pollution on human health. Reconnaissance survey of 19 selected construction sites in Delhi-NCR has been conducted for the period January 2013 to December 2013 and health related data of people in the vicinity of construction sites has been collected individually through a questionnaire. The air quality data (for pollutant PM10) for the area in which the selected construction sites lie has been obtained from the continuous monitoring stations of Central Pollution Control Board. The monthly average PM10 concentration in the ambient air for the study period has been obtained for all the sites. The annual average PM10 level of all the sites has been estimated and compared with the prescribed value. Also the air pollution index (API) (for pollutant PM10) has been calculated for each site and compared with the percentage of people suffering with respiratory problems at the respective sites. The results show that the construction sites where the value of API for PM10 is higher there the percentage of people suffering with respiratory diseases has also been higher.

Interest in air pollution investigation of urban environment due to existence of industrial and commercial activities along with vehicular emission and existence of buildings and streets which setup natural barrier for pollutant dispersion in the urban environment has increased. The air pollution modelling is a multidisciplinary subject when the entire cities are taken under consideration where urban planning and geometries are complex which needs a large software packages to be developed like Operational Street Pollution Model (OSPM), California Line Source model (CALINE series) etc. On overviewing various works it can be summarized that the air pollutant dispersion in urban street canyons and all linked phenomenon such as wind flow, pollutant concentrations, temperature distribution etc. generally depend on wind speed and direction, building heights and density, road width, source and intensity of air pollution, meteorological variables like temperature, humidity etc. A unique and surprising case is observed every time on numerous combinations of these factors. The main aim of this study is to simulate the atmospheric pollutant dispersion for given pollutant like carbon monoxide, sulphur dioxide and nitrogen dioxide and given atmospheric conditions like wind speed and direction. Computational Fluid Dynamics (CFD) simulation for analysing the atmospheric pollutant dispersion is done after natural airflow analysis. Volume rendering is done for variables such as phase 2 volume fraction and velocity with resolution as 250 pixels per inch and transparency as 20%. It can be observed that all the three pollutant namely nitrogen dioxide, sulphur dioxide and carbon monoxide the phase 2 volume fraction changes from 0 to 1. The wind velocity changes from 3.395Ć10-13 m/s to 1.692Ć102 m/s. The dispersion of pollutants follow the sequence Sulphur dioxide>Carbon monoxide>Nitrogen dioxide.

Assessment of Sulphur Dioxide Levels in Selected Sites in Athi River, Kenyaijtsrd
Ā
Industrialization, economic growth, urbanization and population growth have been responsible for air pollution in developing countries. The discharge of harmful chemicals and increased combustion of fossil fuels, affect both the physical environment and the public health. Air pollution effects are both acute and chronic on human health, ranging from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults. A study was conducted to assess the effect of sulfur dioxide on air quality at three sites in Athi River town, Kenya which included one non-industrial site. The air samples were collected by scrubbing them through appropriate trapping solutions and subsequently analyzed in the laboratory using colorimetric method. The meteorological parameters namely; temperature, relative humidity, wind speed and wind direction were also measured during the sampling exercise. The mean concentrations of sulphur dioxide at the various sampling sites during rainy season were: Shalom Hospital (602 -Āµg/m3); Vannilaz Restaurant (793 -Āµg/m3); Redeemed Gospel Church (861 -Āµg/m3) and Sabaki residential Estate (370 -Āµg/m3). The levels exceeded the guidelines recommended by WHO which has set a maximum of 500 -Āµg/m3, for 10 minutes exposure, however the levels at Sabaki residential Estate were low. Mean concentrations of sulphur dioxide during the dry season for Shalom Hospital, Vanillaz Restaurant, Redeemed Gospel church and Sabaki residential Estate were 863, 875,862 and 664 -Āµg/m3 respectively. The elevated levels of SO2 was associated with heavy vehicular traffic and the various industrial activities mainly cement manufacturing plants. Sulphur dioxide may also be emitted from diesel-powered vehicles and coal burning in the industries. The study revealed that Shalom Hospital, Vanillaz Restaurant and Redeemed Gospel Church were polluted with sulphur dioxide during the rainy season except Sabaki residential Estate but during the dry season all the sites were polluted with sulphur dioxide.

a common place term that our ears are attuned to. We hear
about the various forms of pollution and read about it through
the mass media. Air pollution is one such form that refers to the
contamination of the air, irrespective of indoors or outside. A
physical, biological or chemical alteration to the air in the
atmosphere can be termed as pollution. Thus air pollutants are
substances emitted into the air from an anthropogenic, biogenic,
or geogenic source, that is either not part of natural atmosphere
or is present in higher concentrations than the natural
atmosphere, and may cause a short term or long term adverse
effect. It occurs when any harmful gases, dust, smoke enters into
the atmosphere and makes it difficult for plants, animals and
humans to survive as the air becomes dirty. A WHO report
released in May 2014 showed that most of Indian cities are death
traps due to very high air pollution levels. The urban air quality
database of WHO, covering 1600 cities across 91 countries
showed that Indian cities are among those with highest levels of

Urban Air Quality Modelling and Simulation: A Case Study of Kolhapur (M.S.), ...IDES Editor
Ā
As a consequence of urbanization a phenomenal
surge has been observed in the vehicular population in India,
giving rise to elevated levels of traffic related pollutants like
carbon monoxide, nitrogen oxides, hydrocarbons, and
particulates in Indian urban centers. These pollutants can
have both acute and chronic effects on human health. Thus
air quality management needs immediate attention. Air
quality models simulate the physical and chemical processes
occurring in the atmosphere to estimate the atmospheric
pollutant concentration. A variety of air quality models are
available ranging from simple empirical models to complex
Computational Fluid Dynamic (CFD) models. Air quality
models can be a valuable tool in pollution forecasting, air
quality management, traffic management and urban planning.
This paper evaluates the performance of widely used Danish
Operational Street Pollution Model (OSPM) under Indian
traffic conditions. Comparison between predicted and observed
concentrations was performed using both quantitative and
statistical methods. OSPM was found to perform exceedingly
well for the prediction of particulates whereas NO2 predictions
were poorly predicted.
Assessment of Ambient Air Quality of Hoshangabad of M.P.ijtsrd
Ā
Air quality assessment is frequently driven by the need to determine whether a standard or guideline has been exceeded. This overshadows another objective of air quality assessment providing the information needed to estimate population exposure to air pollution and the effects on the health of the population. In this study analysis of air pollutants such as PM10, PM2.5, SO2, and NO2, were assessed to determine the ambient air quality of Hoshangabad City. The PM10 and PM2.5 were found moderate for residential area i.e. Meenakshi Chowk and higher than the permissible limit for other monitoring stations. Seasonal variation of PM10 and PM2.5 showed that in winter air quality becomes worst due to low temperature and humidity particulate matter condenses in lower atmosphere. Gaseous air pollutants SO2, and NOx were well below the permissible limit in all the sampling station in all three study years. Seasonal values for SO2 and NO2 were also found within the permissible limits at all the stations and in all the seasons. Deepa Rajput | Dr. O. N.

Exceedance level of air pollutants in an urban area as a toolLaukik Raut
Ā
The air pollution exceedance status of an urban area has been studied for three different location for six
different air pollutants such as Sulphur dioxide (SO2), Oxides of nitrogen (NOx), by Wet chemical method
(West & Gaeke Method & Jacob & Hochheiser Method), Heavy Metal (Pb) by ICP-OES (Perkin Elmer),
and PAHs [benzo(a)anthracene] & Fluoranthene by using GC (Perkin Elmer), and Particulate Matter
(SPM, PM10,) by Federal Reference Method (Rupprecht & Patashnick Co.In) for one annual cyclic season
along with meteorological data (wind speed and direction). Seasonally variation of air pollution
parameters with respect to month throughout one year was studies and it has been observed that a suitable
control over few pollutants is needed in all the land uses. The air purification system is hence evaluated for
varying land uses. These results can be effectively used as tool for designing of air purification system.

Abstract
At present much attention is given to find the evidence linking urban air pollution to acute and chronic illnesses
amongst all groupsā people. Therefore, monitoring of ambient concentrations of various air pollutants as well as
quantification of the pollutant inhaled becomes quite important, specially in view of the fact that in many
countries, policy decisions for reducing pollutant concentrations are mainly taken on the basis of their health
impacts. Amounts of SO2, PM and NOx originating from the city-traffic are not less important than the
emissions from other sources such as residential heating systems and industrial activities. This paper reveals that
concentration for four pollutants namely sulfur dioxide, Nitrogen oxides, Total suspended particulate matter and
respirable suspended particular matter from January 2010 to April 2013. The three year average maximum
concentration of SO2, NOX, RSPM and TSPM are reported to be 5.4 Ī¼g/m3, 32.0 Ī¼g/m3, 127.4 Ī¼g/m3 and 318.6
Ī¼g/m3 at Panjagutta, Paradise, Balanagar and Panjagutta respectively.
KEYWORDS: Transportation, Air Quality, Particulate Matter, Wind Rose, Distribution.

Introduction
Air pollution has been aggravated by
developments that typically occur as countries
become urbanized: growing cities, increasing traffic,
rapid economic development and higher levels of
energy consumption. Most of the cities worldwide
have witnessed severe air quality problems mainly
due to the vehicles. Urbanization has resulted in high
levels of ground level deterioration of air quality.
The investigation of air pollution in mega cities by
Mage et al. (1996) 7, 11 showed that the major
problem affecting these cities is their high levels of
total suspended particles (TSP). Where, some of the
worst forms of air pollutions are found in Indian
cities12.
Air pollutants that are inhaled affect human
health severely by way of damaging the lungs and
respiratory system. Oxides of sulfur can oxidize and
form sulfuric acid, thereby leading to the damage of
lungs and various lung disorders such as wheezing
and shortness of breath. Oxides of nitrogen, on the
other hand, make children susceptible to respiratory
diseases especially in winter season. The main
chemical component of SPM that is of major
concern is lead, others being nickel, arsenic and
those present in diesel exhaust 4.The particle size is
very important both in terms of deeper penetration
into the lungs and fine particles are carriers of toxic
air pollutants including heavy metals and organic
www.ijera.com
compounds. Exposure to particulate matter can cause
adverse health effects including metal toxicity 11, 4.
Many air pollutants have been identified as being
closely related to transportation. This is a non
separable part of any society. It exhibits a very close
relation to the style of life, the range and location of
activities and the goods and services which will be
available
for
consumption.
Advances
in
transportation has made possible changes in the way
of living and the way in which societies are
organized and therefore have a great inuence in the
development of civilizations. The negative effects of
transportation are more dominating than its useful
aspects as far as transportation is concerned 5, 10.
They have been categorized as numerous
environmental pollution factor. All transport modes
consume energy and the most common source of
energy is from the burning of fossil fuels like coal,
petrol, diesel, etc. The combustion of the fuel
releases several contaminants into the atmosphere,
including carbon monoxide, hydrocarbons, oxides of
nitrogen, and other particulate matter 3, 8. The higher
the level of concentration of transport activities, the
higher their environmental impacts are being felt by
the local community. This is particularly the case for
large transport terminals, such as industrial estates,
rail yards and airports. A salient example is
Hyderabad, one of the most important marketing
containers India. The industrial containers are
centrally located with an acute concentration of large

shipments and tens of thousands of truck movements
per day. Many air pollutants have been identified as
being closely related to transportation 5, 7.
Emitted amounts of SO2, PM and NOx
originating from the city-traffic are not less
important than the emissions from other sources such
as residential heating systems and industrial
activities. As in the most of the developing countries,
the road traffic in Hyderabad appears to be the most
important source group contributing to air pollution
especially in city centreās. In these central locations
large traffic volumes and congestion commonly
result in significant degradation of the air quality as a
function of the rate of increase in population and
urbanization 10.
The long term production of this air
pollutant causes the deterioration of the surrounding
environments due to dispersion under different
climatic conditions, such as temperature, relative
humidity, wind speed and wind direction and other
pollutant concentrations. This dispersion is carried
by averaging period with sufficient information is
available on emissions and meteorology of the
pollutants. This borrows functionality from ESRI's
ArcGIS to produce high resolution maps of air
pollution which can be directly used in GIS-based
exposure assessment 6, 12. Wind speed and wind
direction are the mainly dominating factors for air
pollutant dispersion.
Study area:
India is a tropical country. There are around
100 metropolitan cities in India, out of which
www.ijera.com
Mumbai, Delhi, Bangalore, Kolkata, Chennai,
Hyderabad, Ahmadabad and Pune are the 8 cities
that qualify as the top metro cities in country.
Hyderabad is located at latitude of 17Ā° 22ā² 42ā³ North
and longitude 78Ā° 28ā² 30ā³ East. It is the capital city
of the southern Indian state of Andhra Pradesh.
Occupying 650 square kilometers (250 sq mi) on the
banks of the Musi River, it is also the largest city in
the state. As of 2011, the population of the city was
6.8 million with a metropolitan population of 7.75
million, making it India's fourth most populous
city and sixth most populous urban agglomeration.
Coming to transportation of metropolitan is well
connected to many other locations in India, such
as Bangalore, Mumbai, Delhi, Kolkata, Nagpur,
Chennai, Pune, Vishakhapatnam and Vijayawada.
Three of the National Highways (NH) pass through
the city NH-7, NH-9 and NH-202, Five state
highways SH-1, SH-2, SH-4, SH-5 and SH-6 begins.
Where, the roads occupy 10% of the total city area.

Description of sampling sites
Twenty one study areas were selected for
present study. They are the places of heavy traffic
highway roads, residential areas, commercials areas,
industrial estates and sensitive zones. Figure 1 shows
the location of the monitoring sites of SO2, NOX,
TSPM, RSPM and Relative Meteorology.
Geographical location of the sampling sites is
measured using Global Positioning System (GPS)
instrument.

Methodology
Air samples were collected from
residential, industrial and commercial zones for ten
days in a month at each site. Suspended Particulate
Matter (SPM) are monitored on an 8-hourly basis
www.ijera.com
for 24 hr by collecting the particulates on 20.3cm X
25.4cm glass fiber filter (Whattman GF/A) using
ENVIROTECH-APM 460 NL sampler. The flow
rate is maintained at 1.2 l cu.m/min. Glass fibre
filters are equilibrated in desiccators containing
silica gel for 24 h before and after sample collection
and weighed on a pre-calibrated AFCOSET balance
(ER182A). NOx and SO2 are monitored on a 4hourly basis for 24 hr as per the National Ambient
Air Quality Standards (NAAQS, 1998) using
Improved West and Gaeke method for SO2 and
Modified Jacob and Hochheiser method for NO2.
The double beam Shimadzu UV 2450 UV-Visible
Spectrophotometer is used for spectro-photo metric
applications. The samples were collected at the rate
of 5 l min-1 during the entire 24 hrs of sampling
period. Meteorological data is collected from Indian
meteorological department, Hyderabad. The
complete observations were compared with CPCB
standards.

Figure 4 Concentration of the SO2, NOx, TSPM and RSPM at all the location
The yearly average characterization of 21
selected monitoring sites is represented in the Figure
4 in terms of SO2, NOx TSPM and RSPM.
Figure 4 represents, the year average of
SO2 concentrations are decreased at all the
monitoring places except chikkadapally and
paradise. in the years of 2010, 2011, 2012 the year
average concentration ranged from 4.2 to 5.4 Ī¼g/m3,
4.1 to 4.84 Ī¼g/m3 and 4.2to 4.94 Ī¼g/m3
respectively. Three years minimum and maximum
of the average concentration is 4.2 and 5.4 Ī¼g/m3.
Anthropogenic emissions of NOx lead to majority of
all nitrogen inputs to the environment. During the
years of 2010 to 2012, the year averages of NOX
concentration is observed to be from 14 to 32 Ī¼g/m3,
14.1 to 31.7 Ī¼g/m3 and 13.2 to 31.9 Ī¼g/m3
www.ijera.com
respectively. Three years minimum and maximum
of the average concentration is 14.6 and 31 Ī¼g/m3.
In case of RSPM the concentrations are
ranged from 38.3to 108.8 Ī¼g/m3, 35.1 to 108.1
Ī¼g/m3 and 39.2 to 127.4Ī¼g/m3 for the years of 2010,
2011 and 2012 respectively. Three years minimum
and maximum of the average concentration is 35.1
and 127.4 Ī¼g/m3.
During the years of 2010 to 2012, the year
averages of TSPM concentration is observed to be
from 112.1 to 318.6 Ī¼g/m3, 101.5 to 293.2Ī¼g/m3
and 106.6 to 297.7 Ī¼g/m3 respectively. Three years
minimum and maximum of the average
concentration is 101.5 and 318.6 Ī¼g/m3.
Concentrations of RSPM and TSPM are
above than the limits. RSPM is ranged up to 2.12

times and TSPM is ranged from 1.12 to 3.18 times
to the prescribed limits 2-10.
The RSPM
concentrations are lower than the concentrations of
TSPM, it is quit natural but those concentrations are
above than the CPCB prescribed limits. It is caused
due the transportation of the heavy duty trucks and
local transportation sectors 9. The TSPM levels in
Hyderabad urban locations are higher than levels in
metro cities like Kolkata, Mumbai and comparable
with levels in Delhi. Although the objective of this
work is not to find the reasons as to why the levels
are high in Hyderabad, it obviously reflects on large
emissions in Hyderabad if one considers the
meteorological conditions and major national
highway emissions. The high levels of RSPM and
TSPM in Hyderabad suggest that there is a definite
need to measure and control.
According to wind rose diagram it is
observed that in the monsoon and post monsoon
sessions the north is the most predominant direction
(figure 2), during summer and winter seasons the
south is the most predominant direction. During all
seasons the maximum wind speed is observed to be
12m/sec, where as the calm air % during monsoon,
post-monsoon, winter and summer are observed to
be 15.64%, 32, 93%, 29.10% and 10.60%.
The Three Year Average Maximum is
represented in the figure 3, where the paradise and
Panjagutta are having maximum concentrations of
SO2 and NOx, followed by Abids, Balanagar and
Jeedimetla. It is mainly due to the passage of
vehicles only (k).

Conclusions
SO2 and NOx are within prescribed limits
of CPCB Whereas RSPM and TSPM are alarming
pollution status in Hyderabad. Maximum calm air
conditions are observed during post monsoon
seasons. North is the most predominant wind
direction in monsoon, post monsoon seasons, where
as south is during winter and summer seasons. Study
concludes that the heavy traffic zones are
aggregated with remarkable pollutant levels. The
further monitoring of the pollution levels along with
causing agent consideration (Transportation) is
needed to control the pollution levels in and around
the Hyderabad metropolitan.
