Are all chemicals harmful to future generations? Do bug sprays harm babies? What exactly causes air pollution? What type of diseases does pollution cause for humans? If pollutions was to enter a black hole what would happen?
Answer 1:

ARE ALL CHEMICALS HARMFUL TO FUTURE GENERATIONS?

No. Many chemicals degrade within several years. Some chemicals, called halogenates, take many years to degrade and will be in the atmosphere when you have your own children! Some of these chemicals are not being made for use in the United States any more but are sent to other countries or made in other countries. One example is DDT.
--------------------------------
DO BUG SPRAYS HARM BABIES?

Yes. Even if the bug spray doesn't harm you or an adult, babies are very sensitive to them and can be harmed. This is the same for almost all baby animals.
--------------------------------
WHAT EXACTLY CAUSES AIR POLLUTION?

There are two chemical groups that cause air pollution. They are called NOx (nitrates) and VOC's (Volatile Organic Compounds). In southern California, these chemicals come mostly from cars. They undergo a chemical reaction in the air during the day with sunlight and form ozone and other harmful chemicals like peroxyacetyl nitrate. When the sun goes down and people stop driving their cars and go home at night, the amount of pollution decreases. In other parts of the country, another chemical group also causes pollution. It is called SOx (sulfates). This comes from coal-burning power plants and works much like NOx.

WHAT TYPE OF DISEASES DOES POLLUTION CAUSE FOR HUMANS?

Pollution can cause asthma in children and give many children allergies. In older people with heart problems, pollution will make their heart worse. If the pollution is really bad, pollution will make your chest hurt and eyes water and sting. Many people loose their ability to breath well after living in air pollution for several years. I have only 85% of my lung capacity due to pollution.
--------------------------------
IF POLLUTION WAS TO ENTER A BLACK HOLE WHAT WOULD HAPPEN?

The whole chunk of pollution would shrink down to a very tiny speck because the gravity is so strong in a black hole. Even light is attracted to a black hole! But because black holes are so far away it would be too expensive to transport pollution there. Besides, who would drive?


Answer 2:

ARE ALL CHEMICALS HARMFUL TO FUTURE GENERATIONS?

Everything you see and everything you are, are made up of chemicals....so to answer your question, in short, No. The food you eat helps you.....if your food was contaminated then it might hurt you either short term or long term.
So to answer your question, which is extremely broad--what do you think?
Are Pesticides bad or good?They can do damage when improperly used, but they have increased the amount of food available.

Answer 3:

WHAT EXACTLY CAUSES AIR POLLUTION?

This has been a popular question. I have sort of addressed it in several other of the questions posted, so please read those answers. There are all different types of air pollution. The three main areas of current concern in atmospheric pollution (at least those that I know about) are acid rain, ozone depletion, and greenhouse gases. Acid rain is when pollutants in the atmosphere cause the rain that falls to be much more acidic than normal. Acid rain, like acid, erodes structures and contaminates fresh water ponds, lakes and rivers. Organisms need around neutral pH (not acidic and not basic) to live. If their environment becomes too acidic or basic, the organisms will die. Also, acid rain is not very good for humans as you might have guessed. This is particularly bad if the acid rain contaminates the drinking supply. Acid rain also causes deforestation. Acid rain is mostly a problem for highly industrialized parts of the world, particularly industry that requires a lot of fossil fuel burning. Burning of fossil fuels produces nitrogen and sulfur "oxides" that mix with hyrdo-chloric acid in the atmosphere to produce acid rain. There is a lot of fossil fuel burning industry in the United States' mid-atlantic/Ohio valley region which contains Pennsylvania, Ohio, and West Virginia, among other states.
Greenhouse gases I have discussed in previous questions. Carbon dioxide is the main problem gas because it has been steadily increasing for the last 100 years or so at a very high rate. Just like a greenhouse works to allow the sunlight to come in through the glass windows and heat up the inside (where the plants are growing) but not let the heat escape, this is exactly how the greenhouse gases work. The presence of carbon dioxide, methane and water vapor in the atmosphere allows the sunlight to get to earth and then traps the heat from the sunlight in the earth's atmosphere, so the earth heats up. -Why is the global warming a problem?
Ozone depletion is something that is occurring in the highest level of the atmosphere, the stratosphere, where ozone is normally found. Ozone is a very necessary part of earth's atmosphere. It acts like a filter to the sunlight. White (visible) light can be broken into a rainbow of colors representing the visible spectrum. However, there are other types of "light" that have more and less energy than the visible types of light that humans can see, for example UV light/radiation has more energy than white light. Infrared has less energy than white light. Humans can't see these other types of light, but some organisms can. The sun produces "light" or radiation in all these types (or levels of energy). Certain types of light are very harmful to life on earth, for example very short UV radiation (=very high energy) will damage a cell's DNA and cause cancer in all organisms. The ozone layer protects life on earth from the sun's damaging UV rays by absorbing the UV but letting the visible light/white light to pass and reach the surface of the earth. So life on earth is very dependent on the ozone layer for protection. Man-made chemical compounds such as CFCs (freon) break the ozone down. A huge ozone "hole" was found over Antarctica due to worldwide production of CFCs. The world's industrial nations have banned use and production of CFCs to save the ozone layer. But many developing countries still use CFCs and therefore the ozone layer continues to be depleted. CFCs are extremely good refrigerants (freon used in air conditioners and refrigerators) and were commonly found in aerosol cans to help keep the solution suspended (hair sprays, shaving cream, lysol, etc.). They are cheaper and more effective refrigerants and aerosol additives than alternative chemicals. That's why the developing nations can't afford to not use them. Can you think of a way the world's industrial countries might persuade the developing countries to stop using and producing CFCs so that the ozone layer would not continue to be broken down?

Answer 4:

ARE ALL CHEMICALS HARMFUL TO FUTURE GENERATIONS?

First, all things are chemicals. Even you and I are made of millions of chemicals. Some chemicals are harmful, others are only harmful if you get a lot. Some are fatal in extremely small doses. It all depends on the chemical.

--------------------------------
DO BUG SPRAYS HARM BABIES?

Some can. Babies are more sensitive to many chemicals. To be on the safe side, it is best to protect babies and small children from being exposed to insecticides (bug sprays).

--------------------------------
WHAT EXACTLY CAUSES AIR POLLUTION?

Many things can. The worst offenders are cars and factories that burn things. For example, they might burn coal to make electricity.

WHAT TYPE OF DISEASES DOES POLLUTION CAUSE FOR HUMANS?

Pollution can cause anything from a mild irritation of the eyes and throat to lung damage to death depending on the concentration. Check out these sites on air pollution:

thanks for asking,

Answer 5:

> ARE ALL CHEMICALS HARMFUL TO FUTURE GENERATIONS?
The answer to this is complex. Maybe not all chemicals are hamful, but sometimes we can think for a long time that some chemical is not harmful and then discover later that it is. So to be safe, it is best to limit the amount of chemicals we put in our oceans and air. An example is chlorofluorocarbons, or CFC's. CFC's are used in refrigerators and used to be used in spray cans. People used to think this chemical was
completely harmless, but now we know that it is destroying the ozone in the stratosphere, and that causes more people to get sun burnt and skin cancer.

> WHAT EXACTLY CAUSES AIR POLLUTION?
The cause of air pollution depends on the specific type of pollution. Most air pollution comes from burning stuff. Coal and oil and gasoline, for example, all have sulpher in them. That's just the way these things are. The sulpher is natural. But when people burn them the sulpher turns into sulpher dioxide, which makes smog. Sometimes people put pollutants into things they burn for a good reason, but they don't see the bad result. For example, they used to put lead into gasoline to help cars run better, but when the gasoline burned, the lead would get into the exhaust and settle by the roadside and get into plants and into the ground water. Where did the lead come from originally? Lead comes from rock in the ground. It is not considered a pollution there becuase it is trapped inside minerals in the rock. But people who wanted to make cars run better would mine the rock that had the lead (the still do this because we use lead today for a lot of other things) and would put some in the gasoline. So in the case of lead the pollution comes from rock that gets mined for its lead, and then the lead gets put in gasoline by people, and then the lead gets into the air and the ground water by burnign the gasoline inside a car engine.

> WHAT TYPE OF DISEASES DOES POLLUTION CAUSE FOR HUMANS?
Allergies, athsma, cancer, respiratory illness, and lots of others! Sewage type pollution causes problems in people's stomachs and intestines and can cause diseases like giardia, cholera, and other forms of throwing up and diarrhea.

> IF POLLUTION WAS TO ENTER A BLACK HOLE WHAT WOULD HAPPEN?

Well, I wouldn't worry about it. We will never see that pollution again!
