In most of the children’s toys, a toxic chemical remains present. In this respect, which among the following statements is/are correct?
1. The name of the toxic element is phthalates which are esters of phthalic acid.
2. They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility and longevity.
3. They are easily released into environment because there is no covalent bond between the phthalates and plastics in which they are mixed.

The correct answer is option 4, which means that all the given statements are correct regarding the toxic chemical present in children`s toys. Let`s dissect each statement to understand them better.

Statement 1: The name of the toxic element is phthalates, which are esters of phthalic acid. Phthalates are a group of chemicals that are commonly used in plastics and are known to have potential health risks. They are often used as plasticizers to make plastics more flexible and durable.

Statement 2: Phthalates are mainly used as plasticizers, which means they are substances added to plastics to increase their flexibility and longevity. By adding phthalates, plastic toys become softer and more bendable, making them more appealing to children. However, this also means that phthalates can easily leach out of the toys and come into contact with children.

Statement 3: Phthalates are known to easily be released into the environment because there is no covalent bond between phthalates and the plastics in which they are mixed. This lack of a strong bond allows the phthalates to migrate out of the toys and potentially contaminate the surroundings, including air, water, and soil.

In conclusion, all three statements are correct, highlighting the
