help me <<homework
hi
how are you all
this is my homework plz help me
Summarizing choose one of the following paragraph from the reading in part (e-c-d)
c- although most common in office buildings and schools indoor pollution that causes sick-building syndrome can also occur in houses. imagine a typical home. The people who live there burn oil wood or gas for cooking and heating they might smoke cigarettes pipes or cigars. They use chemicals for cleaning . they use products made of particle board which is an inexpensive kind of board made of very small pieces of wood held together with chemical. They use products such as computers fax machines and copiers that are made of plastic . these products give off chemicals that we can not see but we do breathe them in . in some homes carbon monoxide from cars in the house. And in many areas the ground under the building might send a dangerous gas called radon into the home . the people in the house are breathing in a chemical soup.
d- then that causes sick-building syndrome in an office building or school where people don’t smoke or burn oil wood or gas? Experts have discovered several sources of sick-building syndrome among these are mold and bacteria synthetic products and lack of ventilation or the movement of fresh air into and out of the building. In many buildings rain has leaked in and caused water damage to walls and carpets. This allows mold and bacteria can grow. Synthetic (that is man-made) products such as paint carpeting and furniture can be found in all offices and schools. These products release toxic(poisonous) chemicals into the air. Perhaps the most common cause of sick-building syndrome however is lack of ventilation. Most modern office buildings are tightly sealed in other words the windows don’t open so fresh air doesn’t enter the building. In a building with mold bacteria or toxic chemicals lack of ventilation makes the situation more serious.
e- there are several solutions to the problem of sick-building syndrome the most important of these is cleaning the building. First of course experts must determine the specific cause in any one building. Then workers probably need to take out carpets wallpaper and ceiling tiles in order to remove mold and bacteria. Also they need to clean out the air conditioning system and completely rebuild the system of ventilation. They should remove synthetic products and bring in natural products instead if they are available.
