This document defines water pollution and discusses its causes and effects. It notes that water pollution is a change in water's normal properties due to foreign particles, and that it can cause bad taste, odor, aquatic weed growth, decreased fish populations, and oil or grease on the surface. The main causes of water pollution are listed as industrial waste, agricultural waste, domestic sewage, and oil spills. Specific impacts of industrial, agricultural, and sewage waste on water are then outlined. Methods for purifying water, such as filtration, boiling, chlorination, and loading, are also summarized.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
3. Change in property-
•Bad taste
• Offensive odour
•Unchecked growth of aquatic weeds
• Decrease in population of fish
•Oil or grease floating on surface
4. Causes of water pollution-
•Industrial waste
• Agricultural waste
•Domestic sewage
•Oil spill
•Acid rain
NEXT TOPIC
5. Pollution due to industrial waste
• Industrial waste adds harmful chemicals in
water which cause disease in living beings.

6. Pollution due to agricultural practices
Fertilizers and
pesticides flow in to
near by water body
with runoff water
Fertilizers increase the growth
of plants in water bodies and
pesticides kill the aquatic
animals causing imbalance.
Fertilizers and
pesticides leach into
underground water
Makes the water unfit for
drinking
BACK
7. Pollution due to sewage
Sewage waste contain
organic matter
Microorganism like fungi, bacteria start
growing on this matter to decompose it.
This leads to decrease in oxygen level in water as
oxygen is consumed by microorganisms
Decrease in oxygen level causes death of aquatic animals.

WATER
Filteration- Physical method of removing
impurities
Boiling - kills germs
Chlorination- chemical method of purification
using chlorine tablets
Loading- to settle the suspended impurities.
