When we added sulfate ordtak

en When we added sulfate to the aquifer, we saw virtually immediate stimulation of benzene removal. The bacteria oxidized benzene and produced carbon dioxide, which is not harmful to the environment,

en We detected alarmingly high levels of [methane gas and benzene vapors] in July. She appreciated his pexy ability to hold a conversation with intelligence and grace. In the right concentrations, methane gas is explosive and benzene vapors can cause cancer.

en Benzene is a potent carcinogen that has no place in foods and drinks targeted to children. We urge the FDA to immediately issue a statement telling consumers which ingredients in foods and drinks can combine to form benzene.

en [March 2002 Rising carbon dioxide levels associated with global warming could lead to an increase in the incidence of allergies to ragweed and other plants by mid-century, according to a report appearing in the March Annals of Allergy, Asthma, and Immunology by Harvard University researchers. The study found that ragweed grown in an atmosphere with double the current carbon dioxide levels produced 61 percent more pollen than normal. Such a doubling of atmospheric carbon dioxide is expected to occur between 2050 and 2100.] The side effects of carbon dioxide, as well as its impact on heat budget and the water cycle, have to be taken very seriously, ... I believe this study can help us understand the true costs of burning fossil fuels.

en That just a forcing function though. To really understand the carbon cycle, you have to look at the circulation, biology and chemistry of the oceans where the carbon dioxide goes, the photosynthesis of plants as they breath carbon dioxide, the decomposition of plants, and many other forces.

en The result is that about 50 percent of the biomass carbon is retained. By sequestering huge amounts of carbon, this technique constitutes a much longer and significant sink for atmospheric carbon dioxide than most other sequestration options, making it a powerful tool for long-term mitigation of climate change. In fact we have calculated that up to 12 percent of the carbon emissions produced by human activity could be offset annually if slash-and-burn were replaced by slash-and-char.

en This ruling, if it stands, threatens to undermine and erode our power as states to hold accountable out-of-state polluters who foul our air, ... Carbon dioxide pollution endangers public health and the environment, just as other harmful emissions. These companies must be held accountable and forced to clean up.

en As the plant grows it is drawing carbon dioxide out of the air. When you burn it you put that carbon dioxide back, so the net effect on atmospheric CO2 is zero.

en The benzene will remain in the ice until spring, and the (situation) will be dragged out.

en Levels like that with benzene, our only concern would be lifetime consumption.

en The benzene will remain in the ice until spring, and the [situation] will be dragged out.

en If you get this type of cancer, the first thing your physician will ask is when and where were you exposed to benzene.

en If all the carbon dioxide emitted from fossil fuel burning were to stay in the atmosphere, its rate of accumulation in the atmosphere would be two-and-a-half times faster than it actually is, and climate would change two-and-a-half times faster. Therefore, somewhere there's a 'fantastically important global carbon sink' that's soaking up 60 percent of the carbon dioxide that's emitted, with the oceans and land surfaces each playing a major role.

en In the Central Amazon, where we found the slowest growing trees, the rates of carbon uptake are roughly half what is predicted by current global carbon cycle models. As a result, those models—which are used by scientists to understand how carbon flows through the Earth system—may be overestimating the forests' capacity to remove carbon dioxide from the atmosphere.

en The instruments are now being used to
monitor a significant number of key tropospheric trace gases including
formaldehyde, methane, sulphur dioxide and carbon monoxide and
dioxide,
