2. Purpose & Objective
The Purpose of this study was to identify the major types of pollution
due to construction and destruction sites and its impacts on humans ,
aquatic life , wildlife and ecology . Our objective was also to recognise
the types of pollutions and give few ideas to control it and aware people
at that sites about pollution due to construction . The overall aim of the
proposed study was to understand the link between the construction
sites and how they pollutes the different components of the
environment.

3. Pollution Caused by
construction Activities
The pollution consists of any change of the environment in physical,
chemical or biological characteristics which might be endanger the human
life and other life being.
The construction industry is a major source of pollution compound around
4% of particulate emissions, higher occurrences of water pollution incidents
than any other industry and frequent complains of noise every year.
However, the main areas of concern are including Air, Water, Noise and Soil
pollution.
Construction industry at site has full of danger, difficult and dirty or even
death syndrome which are to be encountered and control under certain
rules & regulations. However, these rules & regulation of environmental
protection can be imposed by the local statutory, government, and any
other independent institutions.

4. Soil Pollution due to Construction
sites
Soil pollution means the presence of toxic chemicals in soil high
enough concentrations to be of risk to human health or to
ecosystem.
Construction sites are important causes of soil pollution in urban
area to their almost ubiquitous nature. In general, any chemical
handled at construction sites may pollute the soil.
Construction dust may easily spread by air and is dangerous due to
its lower particle size. The sites that involve demolition of older
buildings may release asbestos. This may act as a poison in soil. It
may be redistributed by wind.

7. Noise Pollution due to Construction
Site
Sound that is unwanted or that disrupts
the activity or balance of human or animal
life is called as noise. When there is lot of
noise in the environment, it is termed as
Noise Pollution.

8. Noise while Constructing
 A major source of noise pollution, is
emitted by construction equipment,
which defines as "equipment utilized
at construction sites for the
fabrication, erection, modification, or
removal of any structure or facility.
 But unlike industrial equipment, which
emits noise that primarily affects
workers within a facility, construction
equipment tends to be used outdoors,
and thus affects many other people
besides the workers at the site.

10. Noise table
 One recent study conducted at the University of Florida found that sound from
common power tools such as a belt sander, router, circular saw, ranged between 97
and 108 decibels. The study was conducted using these tools in an indoor
environment and reading the sound levels at a distance of 0.6 meters from the tool
99 – 102 dB102 – 111 dB 93 – 96 dB
90 – 96 dB 87 – 94 dB

11. Effects of Noise Pollution
 Hearing Problems: Any unwanted sound that our ears have not been
built to filter can cause problems within the body. Our ears can take
in a certain range of sounds without getting damaged. Man made
noises such as jackhammers, horns, machinery, airplanes and even
vehicles can be too loud for our hearing range.
 Effect on Wildlife: Wildlife faces far more problems than humans
because noise pollution since they are more dependent on sound.
 Sleeping Disorders: Loud noise can certainly hamper your sleeping
pattern and may lead to irritation and uncomfortable situations.
 Health Issues: Excessive noise pollution in working areas such as
offices, construction sites, bars and even in our homes can influence
psychological health.

12. Air pollution due to
Construction
 Construction activities that contribute to air pollution include: land clearing,
operation of diesel engines, burning, and working with toxic materials. All
construction sites generate high levels of dust (typically from concrete, cement,
wood, stone, silica). Construction dust is classified as PM10 - particulate matter
less than 10 microns in diameter, invisible to the naked eye.

13.  Research has shown that PM10 penetrate deeply into the lungs and cause a
wide range of health problems including respiratory illness, asthma and even
cancer. Another major source of PM10 on construction sites comes from the
diesel engine exhausts of vehicles and heavy equipment. This is known as
diesel particulate matter (DPM) and consists of sulphates and silicates, all of
which readily combine with other toxins in the atmosphere, increasing the
health risks of particle inhalation.

14. Water pollution due to
Construction
 Sources of water pollution on building sites include: diesel and oil; paint,
solvents, cleaners and other harmful chemicals; and construction debris
and dirt. When land is cleared it causes soil erosion that leads to silt-
bearing run-off and sediment pollution. Silt and soil that runs into natural
waterways turns them turbid, which restricts sunlight filtration and
destroys aquatic life.

15.  Surface water run-off also carries other pollutants from the site, such as
diesel and oil, toxic chemicals, and building materials like cement. When
these substances get into waterways they poison water life and any animal
that drinks from them. Pollutants on construction sites can also soak into
the groundwater, a source of human drinking water. Once contaminated,
groundwater is much more difficult to treat than surface water.

16. Conclusion
Our studies have concluded the environmental impacts associated with the
Construction and Destruction of building and various sites . The report is surmised
as the assessment of the environmental aspects is made before the building
construction stage :
• The impacts should be minimised and kept under the relevant criteria.
• cumulative construction dust impacts are expected to be within the dust criteria
• Mitigation measures such as quiet plant , moveable noise barriers and limiting
the use of PME have been recommended.
• The potential impacts on water can be controlled by onsite mitigation measures
such as proper handling of toxic chemicals and wastes
• Good waste management practices have been recommended to ensure that
adverse environmental impacts from the handling and disposal of construction
wastes are prevented or minimised.
• Mitigation measures should be taken in the form of good construction practice
and use of quieted construction plant / equipment's
• No direct impact to ecological resources such as woodland , grassland ,
cultivated land , streams and channels should be take care off.
