Standards for portable gas cans will take effect in EPA says the rule will cost an average of 0. According to the rule, reduced evaporation from gas cans due to the new standards "will result in fuel savings that will more than offset the increased cost" for the can.
Environmental activists, who sued EPA to issue the regulation after the agency missed statutory deadlines, are generally pleased with the rule, though they are troubled by one provision. The rule allows refineries that reduce their gasoline's benzene levels to below the new standard to sell "credits" to refineries that can't meet the limit.
Environmental groups fear this will lead to uneven implementation of the rule across the nation, causing residents in some areas to be exposed to more benzene than residents in other areas.

Not Now. Grab your lab coat. Benzene leaks from underground storage tanks or from hazardous waste sites containing benzene can contaminate well water. People working in industries that make or use benzene may be exposed to the highest levels of it.
A major source of benzene exposure is tobacco smoke. How benzene works Benzene works by causing cells not to work correctly. For example, it can cause bone marrow not to produce enough red blood cells, which can lead to anemia. Also, it can damage the immune system by changing blood levels of antibodies and causing the loss of white blood cells. The seriousness of poisoning caused by benzene depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the exposed person.
Immediate signs and symptoms of exposure to benzene People who breathe in high levels of benzene may develop the following signs and symptoms within minutes to several hours: Drowsiness Dizziness Rapid or irregular heartbeat Headaches Tremors Confusion Unconsciousness Death at very high levels Eating foods or drinking beverages containing high levels of benzene can cause the following symptoms within minutes to several hours: Vomiting Irritation of the stomach Dizziness Sleepiness Convulsions Rapid or irregular heartbeat Death at very high levels If a person vomits because of swallowing foods or beverages containing benzene, the vomit could be sucked into the lungs and cause breathing problems and coughing.
Direct exposure of the eyes, skin, or lungs to benzene can cause tissue injury and irritation. Showing these signs and symptoms does not necessarily mean that a person has been exposed to benzene. Long-term health effects of exposure to benzene The major effect of benzene from long-term exposure is on the blood. Long-term exposure means exposure of a year or more.
Benzene causes harmful effects on the bone marrow and can cause a decrease in red blood cells, leading to anemia. It can also cause excessive bleeding and can affect the immune system, increasing the chance for infection. Some women who breathed high levels of benzene for many months had irregular menstrual periods and a decrease in the size of their ovaries. It is not known whether benzene exposure affects the developing fetus in pregnant women or fertility in men.
Animal studies have shown low birth weights, delayed bone formation, and bone marrow damage when pregnant animals breathed benzene. Long-term exposure to high levels of benzene in the air can cause leukemia, cancer of the blood-forming organs. How you can protect yourself, and what to do if you are exposed to benzene First, if the benzene was released into the air, get fresh air by leaving the area where the benzene was released. Moving to an area with fresh air is a good way to reduce the possibility of death from exposure to benzene in the air.
If the benzene release was outside, move away from the area where the benzene was released. If the benzene release was indoors, get out of the building. Removing your clothing Quickly take off clothing that may have benzene on it. Any clothing that has to be pulled over the head should be cut off the body instead of pulled over the head. If you are helping other people remove their clothing, try to avoid touching any contaminated areas, and remove the clothing as quickly as possible.
Washing yourself As quickly as possible, wash any benzene from your skin with large amounts of soap and water. Prolonged exposure to high or low benzene causes leukaemia and impacts red and white blood cells.
The WHO has not set a standard for ambient benzene concentrations, stating that there is no safe level of exposure but many countries use an annual average standard of 3.

Benzene evaporates into the air very quickly. Its vapour is heavier than air and may sink into low-lying areas. Benzene is the simplest aromatic hydrocarbon and distinguished as the first aromatic hydrocarbons with the nature of its bonding first established in the 19th century.
Benzene is widely used in the United States. It ranks in the top 20 chemicals for production volume. Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers.
