health hazards.

Answer 1

Health hazards abound our daily lives in every way and in every place. Some of the hazards are self-created, while others are due to activities of people around us.
The primary health hazard from time immemorial has been the use of tobacco and tobacco products. We smoke, chew and even brush our teeth with tobacco, knowing fully well we are slow-poisoning ourselves with a killer product. Cancer stalks smokers just as much as the other users of tobacco and yet we find it difficult to get of the addiction.
Another health hazard is overeating or consuming too much of fast food. Obesity is the single biggest epidemic in some countries and yet people keep gorging on more and more food, without even realising the harm they are causing to themselves.
Health hazards like air pollution are a big nuisance of modern life in cities. People keep buying cars at a frenetic pace, adding to the pollution of the surrounding atmosphere, making the cities unbearable to live in. The Government must treat this as an emergency and take measures without further ado.
Another health hazard is water pollution, mostly due to industrial effluents trickling into our rivers and streams. Some work has been done in this regard, but we have much more to do. Here too Government intervention is necessary. In many areas of the country, the arsenic content in drinking water is too high; this too deserves action on a war footing. 
 

Answer 2

Any chemical that has been scientifically proved to have harmful effects on health, due to continuous exposure to it, is considered to be a health hazard. Such chemicals can be found in the workplace and in the homes.

Some of the scientifically proved hazards are toxic materials like asbestos, lead and chemical pesticides which are harmful for human health. For example, lead poisoning in children leads to reduced IQ, insomnia, hyperactivity, learning and reading disabilities, impaired growth, hearing loss, and a number of other intellectual, health, and behavioral problems.

Carbon monoxide and radon are some poisonous gases which pose a threat to health. It is found that carbon monoxide poisoning causes more than 200 accidental deaths every year and, at lower levels, leads to flu-like symptoms. Radon may increase the risk of cancer.

Therefore it is necessary to take care and avoid these chemicals in our homes and workplaces. Techniques should be used to ensure proper ventilation and maintain the suitable quality of air in the surroundings.
