The document discusses cotton production and its risks to the environment and human health. It notes that China is the world's largest cotton producer, harvesting 4.6 million tons annually, while India has the largest area under cotton cultivation. Cotton production contributes to various environmental problems like pollution from pesticides, soil salinization from irrigation, and greenhouse gas emissions. It also presents health risks as many cotton farmers in developing countries lack safety awareness and protections when handling highly toxic pesticides. Improper disposal of pesticide containers also leads to water contamination. The document analyzes major pesticides used in cotton and their toxicity classifications from the WHO. It suggests various measures for safer pesticide use and storage.
2. cultivation
Cultivated in over 80 countries worldwide The
world’s largest producer is China where farmers
harvest 4.6 million tones of fiber annually.
While the Indian cotton harvest totals is
2.3million, India has the largest area under cotton
cultivation, over 8.3 million hectares located
mainly in the country’s North and West.
The most productive cotton producer in the
world is Australia which harvests an average
1,689 kilos of fibre per hectare.
3. Risk Of Environment
• These pesticides are washed out of soils, and pollute
rivers and groundwater. Furthermore, the chemicals
eliminate not only pests but also their natural enemies.
• cotton requires large amounts of water for irrigation.
This causes Soil Salinization
• The diversion of entire rivers into huge irrigation
channels in Central Asia has led to the step by step of
the Aral Lake one of the largest inland waters in the
world. It is estimated that 60% of irrigation water in
Central and Southern Asia is lost before reaching cotton
fields because of poor infrastructure
4. Risk Of Environment
• Cotton production also contributes to climate
change. Industrial fertilizers are produced using
considerable quantities of energy sources (1.5% of the
world’s annual energy consumption), releasing large
amounts of carbon dioxide.
• using the large amount of nitrates to agricultural land
leads to their being transformed into nitrous oxide
(“laughing gas”), a greenhouse gas that is 300 times
more destructive than CO 2 in terms of global warming.
5. Risk Of Chemical
Pesticide Toxicity Classification The World Health
Organization classifies pesticides according to
acute toxicity, LD50 denotes the amount of a
chemical required to kill 50% of an exposed
population of laboratory rats. There are two
measures for each product,
1) Oral LD50 (the product is administered orally)
2) Dermal LD50 (the product is administered through the skin).
Oral LD50 Dermal LD50 mg per kg body weight required to
kill 50% of rat population
6. 99% of the world’s cotton farmers live
and work in the developing
World where low levels of safety
awareness
• LACK OF ACCESS TO PROTECTIVE
APPARATUS
• ILLITERACY
• POOR LABELLING OF CHEMICALS
• POOR KNOLDGE OF SAFEGUARDS
WHY…?
7. Re using Pesticide
containers
resold and reused for
caring drinking
Water.
Use those bottle for
playing
Like these activities
can be extremely
poisoning to human
body
Mix the chemical and
empty can bottle in to
the water sources and
pesticide comes into
the body
8. Pesticides on a plate..?
In 2000, AN INTERNATIONAL
STUDY
found traces of
Highly toxic cotton-related
Pesticides in beef, sheep fat,
Chicken, fish, eggs, dairy
Products, Root vegetable
Produced in Uzbekistan.
Separate study by the world
Bank Found that most of
Uzbekistan’s food products Do
Not Meet National Food Quality
Standards Due to contamination
by cotton pesticide

• Use the special area for store the chemical
