Even a small amount of benzene exposure can cause temporary nervous system disorders, immune system depression, and anemia. High levels of benzene can result in death, drowsiness, dizziness, rapid heart rate, headaches, tremors, confusion, unconsciousness, vomiting, and stomach irritation. Benzene has been identified as a carcinogen and can cause various forms of leukemia from as little as five years of exposure, resulting in death in some instances.

Alcohol in the mother's blood crosses the placenta freely and enters the embryo or fetus through the umbilical cord. The exact mechanism(s) by which alcohol damages the fetus and critical times of exposure are not known; however, exposure during the first trimester results in the structural defects (i.e., facial changes) characteristic of FAS, whereas the growth and CNS disturbances could occur from alcohol use during any time in pregnancy.

If not detected early, children with high levels of lead in their bodies can suffer from damage to the brain and nervous system, behavior and learning problems, slowed growth, hearing problems and headaches. Lead is also harmful to adults. Adults can suffer from difficulties during pregnancy, high blood pressure, digestive problems, nerve disorders, memory and concentration problems, and muscle and joint pain.

Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens, irritants, and in some cases, potentially toxic substances. Allergic reactions to mold are common and include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash. Molds can also cause asthma attacks in people with asthma who are allergic to mold.

If someone in your home is odor sensitive, it may be a short discomfort only. The exposure level is very low and short term; therefore good ventilation and air exchange should take care of the odors. If ventilating and vacuuming doesn’t help try to have a hot water extraction done on the new carpet.

Yes. You want to prevent dry mouth if possible, because it can cause difficulty in tasting, chewing or swallowing. It also allows plaque to build up on your teeth faster, leading to a higher risk of cavities. In certain cases, a lack of moisture can make your tongue become very sensitive, causing a condition called burning mouth syndrome. Dry mouth can also lead to bad breath, ulceration or soreness of the mouth, gum disease and difficulty in wearing dentures.

Although H5N1 can cause serious problems to human health, it is difficult to be infected with the virus and, until now, there has been no evidence that it can spread from one person to another. The problem would become most critical if the virus were found to be transmitted from human to human. In the past 100 years there were 4 A-type influenza pandemics that resulted in many deaths around the world.

Radon emits alpha, beta and gamma radiation as it decays. The real danger does not necessarily come from the gas itself but from the products that it produces when it decays. For example; Lead, Bismuth and Polonium. these are actual microscopic particles that attach themselves to dust, pollen, smoke and other airborne particles in a building and are inhaled. Once in the lungs they become trapped and expose the sensitive lung tissue to the harmful radiation they emit as they decay.

Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever-type symptoms, such as sneezing, runny nose, red eyes and skin rash (dermatitis). Allergic reactions to mold are common. They can be immediate or delayed. Molds can also cause asthma attacks in people with asthma who are allergic to mold. In addition, mold exposure can irritate the eyes, skin, nose, throat and lungs of both mold-allergic and non-allergic people.

Plenty. Consumers must gamble that investments in disc players and video collections are in a format that will prevail. And they'll be more cautious embracing digital entertainment technology: "You have to allow consumers to build their digital home over a very long time--a decade. You can't have this fiddle-faddle with standards," said Endpoint Technology Associates analyst Roger Kay.

The email sender is inconsistent in interpreting CSS. The result is that most of the CSS is stripped from the HTML before sending the email. In addition, many Web-based email services will strip the <head> from your email before it is displayed. In either case, the result is that your formatting is lost. CSS is a wonderful technology - so wonderful that HTML editing software tries to use CSS at every opportunity.

The problems of hard water are seen in the home when cooking some foods (e.g. vegetables). These can turn hard and bitter. Hard water also stains bathroom fittings (toilets and bathtubs) and kitchen fittings as well. Likewise, hard water reduces the formation of lather when we bath or wash clothes. Hard water can be treated by "softening it" by chemical processes, which can be carried out in a treatment system in the home.

You will notice that our tours are planned to avoid times when the weather is less favorable to travel. However it is sometimes inevitable to encounter a range of conditions in areas as Patagonia and the Lake District.

At the beginning they are only of cosmetic concern, but later on they can cause clotting (phlebitis), bleeding, ulcers and severe skin changes (dermatitis).

ADHD can cause a range of problems that can vary from child to child. The following are common among all children with ADHD: bull; They often seem to forget things almost instantly. They fail to finish what they start or don’t do it at all. bull; They often seem to be driven like a motor; as a result they can be demanding in class and even behave dangerously when outside. bull; They may seem thoughtless, selfish and rude, so they are often unpopular with other children their age.

Video monitor problems are usually caused by mis-matches of the monitor and the chosen monitor profile. They are usually characterized by no video on the monitor (this could also be due to the system hanging) or un-synchronized video. If no monitor profile is available for your monitor you may need to choose a generic monitor profile. Before doing this, make sure you know what the maximum horizontal and vertical frequencies of your monitor are.

Suggestions for reading about methyl tert-butly ether (MTBE), one of a group of volatile organic chemicals used as solvents, fuel additives, fuels, and disinfection byproducts, is available at the USGS Web page A National Assessment of Volatile Organic Chemicals in Major Aquifer Systems and Rivers. EPA also has a page on MTBE in drinking water. Nitrate (NO3) is a common inorganic form of nitrogen.

Long-term exposure to high levels of benzene in the air can cause leukemia, particularly acute myelogenous leukemia, often referred to as AML. This is a cancer of the bloodforming organs. The Department of Health and Human Services (DHHS) has determined that benzene is a known carcinogen. The International Agency for Research on Cancer (IARC) and the EPA have determined that benzene is carcinogenic to humans.
