VISIT TO A LOCAL POLLUTED SITE
Pollution occurs from a variety of sources and affects different aspects of our environment
and thus our lives and our health.
Polluted sites include urban, rural, agricultural and industrial areas.
Identify the site type and describe the sources of pollution.
Pollution can affect:
• Air (smoke, gases),
• Water (urban sewage, industrial chemical effluents, agricultural pesticides and
fertilisers),
• Soil (chemicals, soild waste from industry and urban areas),
• Biodiversity: effects on plant and animal life.
(Observations on pollution must include all the above aspects.)
GENERAL OBSERVATIONS:
The following aspects need to be observed and documented:
• The type of land or water use in the polluted area, it’s geographical characteristics,
who uses the area, who owns it.
• Map the area to be studied.
• Identifying what is being polluted – air, water, soil; the cause(s) of pollution and the
polluting agent(s).
• Assess the extent of pollution – severe/moderate/slight/nil, to:
air, water, soil, biodiversity.
• Assess from literature, the health aspects associated with the pollutant.
• Ask local residents about its effect on their lives.
• Make a report of the above findings.
PROFORMA FOR FIELDWORK
AIMS AND OBJECTIVES: To study the cause and effects of pollution at the site.
METHODOLOGY: Certain key questions related to the polluted site are given below.
Explore the site to answer the questions about the area you have visited.
• What is the site?
Rural - agricultural area, polluted waterbody, polluted industrial area
Urban - Solid waste management site, Polluted industrial area
• What do you observe at the polluted site?
A solid waste- garbage dump, polluted water at a river or lake, gaseous effluents
or smoke coming out of an industry area, etc.
• Explore the reasons for pollution. Observe and document the components in
the garbage/ the polluted waterbody/ industrial chimneys.
• Observe the area and list the waste that is seen in the garbage dumping site.
Categorise the waste into the three types:
- Degradable wastes, are those which are easily decomposed by micro organisms.
These include food wastes, plant material, animal carcases, etc.
- Non-degradable wastes are those which are not easily decomposed. Eg.
plastic, glass.
- Toxic wastes are those that are poisonous and cause long term effects.
Eg. Several chemicals, paints, sprays, etc.
FINDINGS:
• What are the effects of the pollutant?
• What actions can you take to get the pollution reduced?
