Book Free DemoToxic effects of plastics: The usage of plastics in our daily lives can be hazardous for two reasons.
- The first reason is that some varieties of plastic carry dangerous compounds to our health.
- The second reason is that many plastics are intended to be used only once. As a result, that could adversely affect the environmental pollution.
(a). Harmful plastics:
Toxic and harmful chemicals are used in three types of plastic. These chemicals are added to plastics to improve their flexibility, strength, colour, fire resistance, and UV resistance.
Example:
PVC (resin code #\(3\)), PS (resin code #\(6\), also known as Thermocol), and PC/ABS (resin code #\(7\)) are the three dangerous plastics.
PVC - Polyvinyl Chloride plastics
- Heavy metals (cadmium & lead) are combined with PVC.
- Phthalates (chemical additives) clone our hormones.
- Igniting PVC releases dioxins (one of the most toxic chemicals known to humans).
PS - Polystyrene plastics
- Styrene is a basic block of this plastic and may induce cancer.
- It takes a very long time (\(100\) - \(1\) million years) to decompose.
- Vast amounts of toxic styrene leak into our food and drinks when they are hot or oily.
Polystyrene plastic example (Termocol)
PC - Polycarbonate plastics
- PC plastic includes Bisphenol A (BPA).
- BPA is emitted by PC products used in the preparation of foods and drinks.
- BPA alters the way our bodies work by increasing or decreasing certain hormones.
ABS - Acrylonitrile Butadiene Styrene
- Styrene is harmful to our eyes, skin, digestive system, and lungs.
- BFRs (Brominated Flame Retardants) are frequently used.
- According to studies, this plastic releases toxic chemicals.
(b) One-time use of plastic
Plastics, both used and thrown away, cause both short- and long-term environmental damage.
Throwaway plastic items account for half of all plastic produced today.
Single time used plastics cause health issues for humans, plants, and animals.

Example:
Use and throw away or single-time use plastics.
Plastic cups, plates, carry bags, straws, water pouches, plastic sheets and cutlery used for food wrapping.
