Berkeley study shows ozone and nicotine a bad combination for asthma

Using the unique capabilities of the Chemical Dynamics Beamline at Berkeley Lab’s Advanced Light Source, researchers have demonstrated that ozone can react with the nicotine in secondhand tobacco smoke to form ultrafine particles that may become a bigger threat to asthma sufferers than nicotine itself.

Study reveals dangers of nicotine in thirdhand smoke

Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens. This new potential health hazard was revealed in a multi-institutional study led by researchers with Berkeley Lab.

Berkeley Lab Researchers Participate in Homeland Security Study of Subway Airflow

As part of a Homeland Security study on the spread of airborne contaminants released in subway systems, Berkeley Lab researchers are measuring the flow of gas throughout tunnels and cars.

Berkeley Lab Analysis Finds Reduced Cooling and Heating May Improve Health

Research by Mark Mendell and Anna Mirer of Berkeley Lab’s Environmental Energy Technologies Division suggests that operating buildings in ways designed to save energy – with indoor temperatures slightly cooler in winter and warmer in summer – not only saves energy but improves the health of the occupants and makes them more comfortable besides.

Gauging Indoor Air Quality

Air-quality research has focused on the outdoors even though most people spend the majority of their time indoors. Berkeley Lab’s Environmental Energy Technologies Division has developed a website that provides up-to-date information on how indoor air quality affects human health and work

Berkeley Lab Scientists Find Evidence of Link

Contact: Allan Chen (510) 486-4210 BERKELEY, CA — A team of researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found evidence that the prevalence of building-related symptoms (BRS) increases with increasing outdoor concentrations of the pollutant ozone. They have also discovered that the type of air filter that some

Behind Closed Doors: Beware the Air

Contact: Allan Chen, a_chen@lbl.gov Those factors in the home that cause or exacerbate asthma and allergies in children are not well understood, but scientists agree they include allergens like dust mites, mold, and environmental tobacco smoke. Mark Mendell, an epidemiologist in Berkeley Lab’s Environmental Energy Technologies Division, suggests another set of factors worth investigating: emissions

Berkeley Lab Program Helps Building Managers Prepare for Chemical, Biological, and Radiological Threats

Contact: Allan Chen, (510) 486-4210, a_chen@lbl.gov BERKELEY, CA – A team of researchers at the Department of Energy’s Lawrence Berkeley National Laboratory has developed an interactive computer program that building managers and owners can use to assess their vulnerability to — and to prepare for — chemical, biological, and radiological (CBR) weapons attacks or accidental

When Mold Runs Amok

Contact: Allan Chen, a_chen@lbl.gov Mold growth in buildings and its purported effects on human health have been in the news a lot in recent years. Mold-related litigation and claims against insurance companies for mold and other moisture-related problems in buildings have been on the rise.There is strong scientific and other evidence linking mold and damp
