Question

Write down harmful effects of noise and soil pollution.

Answer 1

Noise pollution is the pollution created by loud sounds of music, vehicles, traffic etc. above the 75 decibels of sound.
Soil pollution is the pollution that affects the fertility of the soil by disposing of various non-biodegradable on barren lands.

Complete step by step answer:
The harmful effects of noise pollution are-
-It can damage our hearing by causing tinnitus or deafness, constant loud noise can damage human health in many ways.
-It causes respiratory agitation, racing pulse, high blood pressure, headaches and, in case of extremely loud, constant noise, gastritis, colitis and even heart attacks.
-Noise can cause attacks of stress, fatigue, depression, anxiety and hysteria in both humans and animals.
-Noise above 45 dB stops us from falling asleep or sleeping properly.
-According to the World Health Organization, noise should be no more than 30 db. Loud noise can have latent effects on our behavior, causing aggressive behavior and irritability.
-Noise may affect people's ability to focus, which can lead to low performance over time. It is also bad for the memory, making it hard to study.
-The harmful effects of soil pollution are-
-It affects human health. Crops and plants that are grown on polluted soil absorb much of the pollution and then pass these on to us. This could explain the sudden surge in small and terminal illnesses.
-Long term exposure to such soil can affect the genetic make-up of the body, causing congenital illnesses and chronic health problems that cannot be cured easily.
- In fact, it can sicken the livestock to a considerable extent and cause food poisoning over a long period of time.
-It affects the Growth of Plants. Most plants are unable to adapt when the chemistry of the soil changes so radically in a short period of time. Fungi and bacteria found in the soil that bind it together begin to decline, which creates an additional problem of soil erosion.
-The fertility of the soil slowly diminishes, making land unsuitable for agriculture and any local vegetation to survive.
-The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield.
-The death of many soil organisms (e.g., earthworms) in the soil can lead to alteration in soil structure. Apart from that, it could also force other predators to move to other places in search of food.

Note:
Soil pollution also leads to the poisoning of the underground water table. Since this water is stored beneath the layers of the soil, the toxins in the soil could easily percolate slowly and steadily into the water table.
Our ears need more than 16 hours' rest to make up for two hours of exposure to 100 dB.
