What are the health hazards which can be caused by e-waste? 

  1. Brain

  2. Lung cancer

  3. DNA damage

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Improper disposal of e-waste releases toxic chemicals that can cause a wide range of health issues, including neurological damage (brain), respiratory issues (lung cancer), and genetic damage (DNA damage).

Multiple choice

E-cigarettes and e-hookahs have what in them?

  1. Formaldehyde

  2. Cancer

  3. Tar

  4. Carbon Monoxide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Studies have shown that the aerosol produced by e-cigarettes can contain harmful chemicals, including formaldehyde, which is a known carcinogen, often formed by the heating of the e-liquid.

Multiple choice

Chemicals that cause cancer are called

  1. carcinogens

  2. hazardous

  3. teratogens

  4. neurotoxins
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carcinogens are specific types of chemical or physical agents that have the potential to cause cancer in living tissue. Other options like teratogens cause birth defects, and neurotoxins damage the nervous system.

Multiple choice physics nuclear physics hazards and safety measures of radiations harmful effects and safety precautions for radiations energy production

Radiation exposure comes from

  1. Background Sources

  2. Manmade sources

  3. Medical processes

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Because of Man made processes , there will be radiation exposure. For example we can take bricks , it causes radiation

Because of Medical processes , we will get several radiation exposures . For example X ray radiation etc
Background sources also causes radiation
Therefore option $D$ is correct

Multiple choice business organisation and correspondence industrial pollution and degradation of environment pollution and industrial pollution pollution and its type pollutions

Cadmium pollution is associated with disease

  1. Itai-itai

  2. Anaemia

  3. Minamata

  4. Pneumoconiosis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Itai-itai is the disease which was caused by the cadmium poisioning due to mining in Toyama Prefecture, Japan. This term was given by the locals for the severe pain the victims felt in the spine and the joints. It can also cause softening of bones and kidney failure. The disease was first described in the menopausal Japanese woman exposed to excessive levels of cadmium over their lifetimes.
