a. Explain the effect and remedial plans of
following materials on environment and
human health
1. Plastic
2. Glass
3. Thermocol.
Answers
Answer:
Plastics occur serious environment pollution such as soil pollution, water pollution, and air pollution. Application of proper rules and regulations for the production and use of plastics can reduce toxic effects of plastics on human health and environment
Glass is also non biodegradable so it is also a pollutant and affect human health. 3. ... Thermocol plates are also used in mass gatherings and if hot food is kept in such plates , the food is harmful for health. The gases released due to the burning of thermocol is also harmful for humans and cause pollution.
Answer:
The effects of the following materials on environment and human health are:
1) Plastic – It is non-biodegradable and a man made material which causes a lot of land pollution. Due to its non-biodegradable characteristics it remains in the soil and water for a very long time, thus causing pollution. The smoke released after burning of plastic is also harmful for human health.
2) Glass – While glass production, mixture needs to be heated up to 1500 ºC. During this, greenhouse gases like sulphur dioxide, nitrogen dioxide, carbon dioxide are released through burning of fuel. As the glass is non-degradable, if pieces of the waste glass material flow into water body, it may affect that ecosystem. Similarly, drainage may be blocked due to these pieces.
3) Thermocol – Being carcinogenic ingredients in styrene, the person in contact with thermocol for long duration may have the possibility of blood cancer like leukemia and lymphoma. It takes a long duration for natural degradation of thermocol; hence many people opt for destroying it by burning. However, it is still more hazardous method as it releases poisonous gases in atmosphere. In mass gatherings, plates and cups used to offer the food, water, tea are made up of thermocol. It affects their health. If the food kept in thermocol is reheated, styrene may dissolve in that food. Due to this, there is possibility of health problems.
