Definition
“Industrial pollution in terms of the activities that release the contamination, what element of the ecosystem the contaminants pollute, and the specific toxic materials that make up the hazard or pollutant”
What is industrial pollution
Industrial pollution is the contamination of the
environment by businesses, particularly plants and factories, that dump waste products into
the air and water.
Industrial waste is one of the largest contributors to the global pollution problem
endangering people and the environment.
History of industrial pollution
The impacts could be far reaching because societies relied on wave
and wind power.
The 18th century, was the increasingly intensive use of
hydrocarbon fuels.
The environment felt the full impact of industrialization in the form of air
and water pollution.
Where do industrial pollutants come from
Waste in the manufacturing industries
Damages from Industrial Pollution
hazardous wastes.
Three Industrious Wastes.
Environmental pollution.
serious consequences .
Lack of Policies to Control Pollution
Unplanned Industrial Growth
Use of Outdated Technologies
Presence of Large Number of Small Scale Industries
Inefficient Waste Disposal
Leaching of Resources From Our Natural World
Causes Of Industrial Pollution
Effect s Of Industrial Pollution
Industrial Causes Of Water Pollution
A. Sewage and waste water The waste water dumped in to the sea or river.
Brings many deadly diseases to us.
B. Industrial wasteIndustries cause huge water pollution with their activities.
C. Ocean and marine dumping
Paper waste, Food waste, Plastic, Rubber, Metallic and aluminum waste. In some countries, they are deposited into the sea.
D. Underground storage and tube leakages
Fire and explosion, Inhalation of dangerous vapors,Contamination of soil and groundwater,Contamination of drinking water,Contamination of streams, rivers, and lakes.
Disruption of food-chains
Industrial Causes Of Air Pollution
Smokes coming out from factories,
industries, homes and vehicles are
causing of air pollution.
The most probable reasons of air pollution is
the manufacturing industries .
These deadly gases are so much
dangerous for human health.
Chemical reactions can also
be harmful for humans.
Industrial Causes of Noise pollution
Noise as hazardous to worker safety and health.
Noise has been a hazard linked to heavy industries such as ship-building.
Noise destroys the peace of human’s minds.
Industrial Pollution Causes Land Pollution
Industrial pollution is the biggest contributors to our polluted
landscapes.
In many industrial nations new land for building homes and schools is hard to find.
Carbon Dioxide
Ozone
Oil Spills
Heavy Metals
Water
Types Of Industrial Pollution
Sources of Industrial pollutants
Asbestos
Lead
Mercury
NitratesSulfur
Oils
Petrochemicals
Industrial Pollution Causes Affecting Urban Land
Industrial land

Testing for pollutants
Mines and factories as
pollution sources
Ecology of Industrial Pollution
The ecological issues associated
with industrial pollution.
Biological resources of mining areas, bio
monitoring of freshwater.
Marine ecosystems.Risk assessment of contaminated land.
Pakistan’s Experience in Industrial Pollution Control
Agreement on the Pollution Charge Amount
Monitoring
Financial Incentives for Industry
Increasing Technical Capacity
Implementing NEQS
INDUSTRIAL SECTOR EMISSION
Many industrial processes emit
CO2 through fossil fuel combustion.
Fossil fuel combustion from various industrial
processes accounted for
about 14% CO2
emissions.
Carbon dioxide is constantly being
exchanged among the atmosphere, ocean, and land
surface .
Human activities have contributed substantially to
climate change by adding CO2
Emissions and Trends
CO2 emissions from fossil
fuel combustion
are influenced by many long-
term and short-term
factors.
Carbon dioxide (CO2) emissions in the United
States increased by
about 5% between 1990 and
2012.
Strategy Examples of How Emissions Can be Reduced
Energy Efficiency Improving the insulation of buildings, traveling in more fuel-efficient vehicles,
and using more efficient electrical appliances are all ways to reduce energy
consumption, and thus CO2 emissions.
Energy
Conservation
Reducing personal energy use by turning off lights and electronics when not in use
reduces electricity demand. Reducing distance traveled in vehicles reduces
petroleum consumption. Both are ways to reduce energy CO2 emissions through
conservation.
Fuel Switching Producing more energy from renewable sources and using fuels with lower carbon
contents are ways to reduce carbon emissions.
Carbon Capture
&Sequestration
Carbon dioxide capture and sequestration is a set of technologies that can
potentially greatly reduce CO2 emissions from new and existing coal- and gas-fired
power plants, industrial processes, and other stationary sources of CO
Industrial water pollution
Pesticides
Fertilizers / Nutrient Pollution
Mining
Chemical and
Industrial Processes
Personal Care Products,
Household Cleaning Products
Sewage
How to solve it..
a. Reducing Nutrient and Pesticide Pollution.
b. Reducing Sewage Pollution.
c. Reducing Pollution from Oil and Petroleum Liquids.
d. Cleaning Up Chemical Pollution.
e. Fighting Global Warming.
WATER TREATMENT PROCESS
The basic methods of treating municipal wastewater fall into three stages:
Primary Treatment.
Secondary Treatment.
Tertiary Treatment.
Industrial Effluents
Contamination of drinking water supplies from industrial waste
Industrial waste consists of both organic & inorganic substances.
An incentive for industry to pre-treat their water by neutralizing the chemically active
components, recycling , extraction and collection for proper disposal.
Industries which Use large Amounts of Water
Chemical manufacturers,
Steel plants,
Metal processers,
Textile manufacturers,
Agriculture,
Fruit and Vegetable Processing,
Petroleum Refining,
Pulp and Paper.
Industrial pollution has adversely affected
biodiversity for the last two centuries and
continues to increase globally.
Agrochemicals are intentionally released into the environment, prohibiting their usage would probably not be
politically or economically feasible.
A slightly generalized plan
based on the different kinds of
solutions available can be proposed for
the different pollutants.
Reducing consumption or usage of a polluting product.
Treatment of wastes, discharges and disposals of a pollutant.
Toxic metals should have a restriction on maximum environmental release based on relative toxicity levels and accumulation rates in ecosystems.
Conclusion
We came to know that industrial pollution adversely affects our environment.
It is difficult for us to identify the optical way for future generations however, we all know a severely polluted earth is not going to be a good place.
Therefore at this moment we should make every effort to reduce every kind pollution to avoid resources waste.
Main problems are;
Usage of dizzying of chemicals in modern industrialization.
Public awareness is lagging behind these problems.
Ecological concerns have been shunted aside in the rush towards industrialization and growth.
Full extent of the ecological disaster emerging.
It dramatically cripples and shortens the life of human beings .
Community health physicians calculate that illnesses traceable to environmental pollution account for more than 30% of the country's health budget.
Officials estimate that one out of 20 people in the country now dies of environmentally-induced causes.
The mass media and government should work on spreading awareness regarding the issue.
It is high time the government takes a stern position in preventing the hazardous situation.
Addition of heavy toxic organic and inorganic materials destroy aquatic life.
Properly centralize factories to reduce waste emission from single area.
Improve burning design of engine and raise burning quality and capacity of gasoline for full burning.
Integrate legal approaches, administrative methods, economic measures, technological methods and thinking education.
