The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Pollution is the introduction of harmful
substances or products into the environment.
.Any undesirable change in the Physical,
chemical and biological properties of land,
water and air that are adversely effect to
human being and others living organism
There are 3 major parts of Pollution.
• Water Pollution
• Air Pollution
• Land Pollution
3. It is defined as any atmospheric condition
in which certain substances are present in
such concentrations that they produce
undesirable effects on humans and
environment.

12. Air Pollutant and their effects
Things that pollute a substance is called a pollutant.
•Air Pollutant
An air pollutant is a substance in the air that can have
adverse effects on humans and the ecosystem. The
substance can be solid particles, liquid droplets, or
gases. A pollutant can be of natural origin or man-
made.
•Pollutants are classified as primary or secondary.
14. •Nitrogen oxides, particularly nitrogen dioxide, are expelled from high
temperature combustion, and are also produced during thunderstorms
by electric discharge.
•Nitrogen oxides (NOX) are emitted during fuel combustion, such as
by industrial facilities and the road transport sector.As with SO2,
NOX contributes to acid deposition.
•NO2 that is associated with adverse affects on health, as high
concentrations cause inflammation of the airways (wind pipe,layrnx).
15. •colourless and odourless,toxic gas
•comes from the incomplete combustion of fuel in vehicles.
•can be absorbed by haemoglobin in the blood, thus blood
can no longer absorb O2
•extra amounts of CO result in tiredness, headaches, heart
damage and small amounts can be lethal
16. •fuels (coal and petroleum) contain sulphur as an impurity;
when fuels are burnt, sulphur is oxidised or burnt to SO2
•also emitted from volcanoes eruptions
•irritates the eyes and causes breathing difficulties causes
asthmetic problems.
•in the presence of a catalyst such as NO2, forms H2SO4, and
results of acid rain.
17. • a gas with a characteristic pungent odor.
• Odors — such as from garbage, sewage, and industrial processes
• Radioactive pollutants - produced by nuclear explosions, nuclear
events, war explosives, and natural processes such as the radioactive
decay of radon.
• come from the agricultural sector, from activities such as manure
storage, slurry spreading and the use of synthetic amonia fertilizers.
18. The heavy metals arsenic (As), cadmium (Cd), lead (Pb),
mercury (Hg) and nickel (Ni) are emitted mainly as a result of
various combustion processes and industrial activities.
•These chemicals are known as toxins and are linked to thyroid
disorders, cancer, women’s hormonal conditions, chronic
fatigue syndrome, fibromyalgia and other several illnesses &
symptoms includes.
•Fatigue
•Lung Cancer
•Cardiopulmonary diseases
19. VOC is emitted from a large number of sources including paint
application, road transport, dry-cleaning and other solvent uses.
• Methane VOC
• Non methane VOC
• Benzene
• Methyl Chloride
• CFCs
20. • Methylene chloride is highly dangerous to human health. It can be
found in adhesive removers and aerosol spray paints and the chemical
has been proven to cause cancer in animals. In the human body,
methylene chloride is converted to carbon monoxide and a person will
suffer the same symptoms as exposure to carbon monoxide.
• Benzene, is a chemical found in environmental tobacco smoke,
stored fuels, and exhaust from cars. Benzene has also been known to
contaminate food and water and if digested can lead to vomiting,
dizziness, sleepiness, rapid heartbeat, and at high levels, even death
may occur.
• Chlorofluorocarbons (CFCs) widely used cleaning products and
refrigerants. Tetrachloroethene is used widely in dry cleaning harmful
to ozone layer which prevents human by having skin cancer and
various skin diseases,
21. -Major SecondaryAir Pollutant
Particulate matter (PM)
Particulates created from gaseous primary pollutants and
compounds in photochemical smog.
•Particulate matter includes both primary and secondary PM;
primary PM is the fraction of PM that is emitted directly into
the atmosphere, whereas secondary PM forms in the
atmosphere following the oxidation and transformation of toxic
gases (mainly SO2, NOX, NH3 and some volatile organic
compounds (VOCs).
•PM is one of the most important pollutants as it penetrates into
sensitive regions of the respiratory system
22. Ground level ozone (O3) formed from NOx and VOCs.
• Ozone (O3) is a secondary pollutant and a key constituent formed in
the troposphere.
• Photochemical and chemical reactions involving it drive many of the
chemical processes that occur in the atmosphere by day and by night.
• At abnormally high concentrations brought about by human activities
(largely the combustion of fossil fuel), it is a pollutant, and a
constituent of smog.
• Ozone is a powerful and aggressive oxidising agent, elevated levels of
which cause respiratory and cardiovascular health problems and lead
to premature mortalit.
• High levels of O3 can also damage plants, leading to reduced
agricultural crop yields and decreased forest growth.
23. • global warming is largely caused by increasing CO2 and other heat
trapping gases (e.g. methane) in the atmosphere.
• large amount of heat trapped on Earth; Earth becomes hotter.
24. Global warming cont.
•It results in rise in sea levels, flooding of low-lying lands,
melting of polar ice caps and changes in global climate.
Measures to reduce global warming-
-use of fossil fuels (to reduce CO2 emission)
-use tidal, wind and hydroelectric energy to generate electricity.
-use of solar energy.
25. •When emissions of sulphur dioxide and nitric oxide from
stationary sources are transported long distances by winds,
they form secondary pollutants such as nitrogen dioxide,
nitric acid vapor, and droplets containing solutions of
sulphuric acid, sulphate, and nitrate salts.
•These chemicals descend to the earth's surface in wet form
as rain or snow and in dry form as a gases fog, dew, or
solid particles, it is known as acid rain or acid deposition
28. • Self awareness to the person that pollution is a
disaster.
• Greening operations.
• Car checks (supply excess air to ensure complete
combustion; fit vehicles with catalytic converters.
• fit vehicles with catalytic converters to avoid
spreading nitrogen oxides in atmosphere.
• Renewable energy
29. •Planting trees
•Avoid purchasing excess amount of products that contain
CFCs.
•The suspension of licenses of industrial activity which
destroys the environment
•Relocation of polluting industries away from places where
people live
•Development of waste and garbage disposal recycling
•Renewable energy law
