In 2017, what did a study of tap water show about pollutants from plastic? Why is this a problem?

8 0

In a new study, the WHO says that microplastics are "ubiquitous" and have been detected in fresh water, wastewater, food, air, bottled water, tap water and more."Based on limited information we have, microplastics in drinking water don't appear to pose a health risk at current levelsWildlife

often mistakes plastic for food. Once the plastic is eaten, it cannot be digested and ends up harming the animal by lodging in the gut. Plastic bags also can suffocate animals. Plastics also leech into the water, degrading the water quality with toxic compounds and end up harming human and animal health.

Answer:

When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.

Explanation:

In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.

As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.
