The uses and health effects of polythene are discussed below-
Introduction:
Polyethylene, which is used in various forms such as polyethylene terephthalate (pet) and low-density polyethylene (ldpe), is an essential component of modern life. it is commonly used to make bags, bottles, packaging and other materials. however, its use and environmental and health implications require a deeper discussion.
Uses of polythene:
1. Packaging: The most common use of polythene is packaging. it is used in the safety and security of foodstuffs, gifts and other products.
2. Bags: From shopping bags to food packaging, polythene bags are extremely popular. they are convenient as they are light weight and waterproof.
3. Home use: various products made of polythene like floor coverings, plastic table cloths etc. are used in homes.
4. In industry: Polyethylene is used in construction and agriculture. it is used in the manufacture of waterproof coatings, plastic films, and various types of equipment.
Health effects:
Along with the use of polythene, its health effects are also important issues-
1. Mhemical effects: certain chemicals like additives and plasticizers are used during the production of polyethylene. these substances can be harmful to the human body. in particular, the presence of bpa (bisphenol a) can cause health problems, such as hormonal imbalance.
2. Air pollution:
Polyethylene is a major cause of air pollution. its production process releases huge amounts of carbon dioxide and other gases, which worsen air quality. burning of polythene produces toxic gases, which cause respiratory problems and other health complications. also, since polythene has a long shelf life, it accumulates in the environment, which disturbs the balance of the environment. for this reason, it is important to reduce the use of polythene and use alternative materials. raising awareness and using recycled materials will help protect our air and environment.
3. Water pollution:
Polyethylene is a serious problem of water pollution. when polythene waste accumulates in rivers, lakes and seas, it harms aquatic animals and plants. polyethylene contains chemicals, which cause water pollution and also have negative effects on human health. aquatic animals ingest polythene and enter the body with toxins, which flow into the food chain. because of this, human food safety is at risk. we can take effective steps to prevent water pollution by increasing awareness and use of recyclable materials instead of polythene.
4. Physical health problems: Pollution caused by polythene can cause people to suffer from various physical problems, such as allergies, skin diseases and other chronic diseases.
Environmental impact:
The use of polythene also has a huge impact on the environment.
1. Waste problem: Recyclability of polyethylene is limited. most polyethylene is disposed of as waste, contaminating soil and water.
2. Impact on biodiversity: Polythene waste is fatal to wildlife. many animals die after ingesting polythene.
3. Dumping problem: In many countries polythene is mismanaged due to lack of proper dumping system, which is very harmful to the environment.
Alternatives to polythene:
Keeping in mind the health and environmental impact of polythene, it is important to explore alternatives.
1. Biodegradable materials: Different types of biodegradable plastics such as castor oil, starch based plastics etc. can be substituted for polythene.
2. Recycled materials: Use of recycled materials like glass, steel and cans can be encouraged.
3. Natural materials: Paper, rattan, and other natural materials can be used instead of polythene, which is more environmentally friendly.
Conclusion:
Although the use of polythene is an integral part of our daily life, its health and environmental impacts are numerous. through awareness and proper management we can reduce the harmful effects of polythene. it is possible to protect the environment by adopting alternative means and fostering a culture of recycling. it is essential for our health and future generations.
