Plastic Pollution

There are concerns about the use of brominated flame retardants (BFRs) for two main reasons: **Statement 1 is correct:** They are highly resistant to degradation. BFRs break down very slowly in the environment, meaning they can persist for a long time. This can lead to them accumulating in the environment over time. **Statement 2 is correct:** BFRs can accumulate in the bodies of humans and animals (Bioaccumulation). This happens because they are fat-soluble, meaning they are stored in fatty tissues.

Because of their small size, marine animals like fish, shellfish, and plankton can easily ingest microbeads. These plastic particles can block their digestive systems, leading to starvation or death. Additionally, microbeads might absorb pollutants and toxins present in the water, concentrating them in the food chain and potentially harming larger predators, including humans.

Triclosan (sometimes abbreviated as TCS) is an antibacterial and antifungal agent present in some consumer products, including - toothpaste, - soaps, - detergents, - toys, - surgical cleaning treatments.

* Bisphenol A (BPA) is a key component in the manufacture of polycarbonate plastics. * Polycarbonate plastics are a type of synthetic plastic material that is known to contain Bisphenol A (BPA) as a structural component. * BPA is used in the production of polycarbonate plastics, which are commonly used in various consumer products such as Water bottles, Food storage containers, Household electronics, Eyeglass lenses, Compact discs (CDs) and digital versatile discs (DVDs) * BPA has raised health concerns due to its potential to act as an endocrine disruptor, which can interfere with the body's hormonal system.

**Statement 1 is correct.** PET fibres can be blended with cotton or wool to improve properties like wrinkle resistance and durability. **Statement 2 is incorrect.** Not all PET containers are suitable for all alcoholic beverages. Some PET can leach chemicals at high temperatures or with certain types of alcohol. It's important to check for specific suitability indicators on the packaging. **Statement 3 is correct.** PET bottles are one of the most commonly recycled plastics. They can be reprocessed into various products like clothing fibres, new bottles, or building materials. **Statement 4 is incorrect.** Incineration of PET, like most plastics, generates greenhouse gas emissions, including carbon dioxide. While PET has a lower emission profile compared to some other plastics, it's still not a zero-emission disposal method. Remember: Statements like store any kind of alcoholic beverages are vague & ambiguous, so they ought to be eliminated. Also, incineration of any substance cannot be environment friendly as it would definitely release GHGs. Hence the only Option left is Option A. Therefore, the correct statements are 1 and 3.

* **Statement 1 is Correct.** PFAS are used in a wide range of consumer products, and due to their persistence, they can leach into the environment and contaminate water sources, food, and packaging materials. * **Statement 2 is Correct.** PFAS are known as 'forever chemicals' because the strong carbon-fluorine bond makes them highly resistant to natural degradation processes. This persistence leads to their accumulation in the environment. * **Statement 3 is Correct.** Because PFAS don't break down easily, they can build up in the tissues of animals and humans over time, leading to potential health concerns.  _Therefore, all three statements are correct._

**Statement-I: Correct.** Chewing gums are a source of environmental pollution due to several factors: * **Non-biodegradable gum base**: Traditional chewing gums often contain polymers like polyisobutylene, polyvinyl acetate, or polyethylene, which do not decompose easily in the environment. * **Littering**: Discarded chewing gum remains on sidewalks, streets, and other public spaces, creating an eyesore and requiring significant resources for removal. **Statement-II: Correct and explains Statement-I** * The plastic-like polymers used as gum bases in many chewing gums are the primary reason they are difficult to biodegrade. These polymers contribute significantly to the environmental persistence of chewing gum litter. Therefore, the correct option is (A): Both Statement-I and Statement-II are correct and Statement-II explains Statement-I.

Many everyday items contain hidden plastics, even if they don’t look like typical plastic products. * ✅**I. Cigarette butts** – Filters are made of **cellulose acetate**, a form of plastic. * ✅**II. Eyeglass lenses** – Usually made from **polycarbonate or CR-39 plastic**, not glass. * ✅**III. Car tyres** – Contain **synthetic rubber**, which includes plastic-based polymers. **All three** items contain plastic.
