Select the set of disease caused by pollution :

Question

Accepted Answer

Option 4, "Minamata and Fluorosis," is the correct answer because both Minamata disease and Fluorosis are directly linked to pollution.

1. **Minamata Disease**: This disease is caused by mercury poisoning, which occurs when industrial waste containing mercury is released into water bodies. The mercury accumulates in fish and shellfish, which are then consumed by humans, leading to severe neurological damage. This condition was first identified in Minamata, Japan, hence the name.

2. **Fluorosis**: This condition is caused by excessive intake of fluoride, often due to pollution of water sources. Industrial activities can lead to high levels of fluoride in drinking water, which, when consumed over time, can cause dental and skeletal fluorosis. This results in discoloration of teeth and damage to bones and joints.

Now, let's explain why the other options are incorrect:

1. **Option 1: Cat-cry-syndrome and Minamata**: Cat-cry syndrome, also known as Cri du Chat syndrome, is a genetic disorder caused by a deletion of a part of chromosome 5. It is not related to pollution. While Minamata disease is caused by pollution, the inclusion of Cat-cry syndrome makes this option incorrect.

2. **Option 2: Hypertension and Marasmus**: Hypertension is primarily related to lifestyle factors such as diet, stress, and genetics, rather than pollution. Marasmus is a form of severe malnutrition caused by a deficiency in calories and protein, not pollution. Therefore, this option is incorrect.

3. **Option 3: Marasmus and Kwashiorkor**: Both Marasmus and Kwashiorkor are forms of malnutrition caused by inadequate intake of nutrients, particularly proteins and calories. They are not caused by pollution, making this option incorrect.

In conclusion, Option 4 is the correct answer because both Minamata disease and Fluorosis are directly linked to pollution, whereas the other options include diseases that are not caused by pollution.
