This long winter has had the AIRE team thinking about the amount of time we spend indoors, and the air quality there.
– These days, most people spend the vast majority of their time indoors (especially in the winter!). There is therefore high potential for exposure to pollutants indoors, i.e., at home or in the workplace.
– While what we think of as commonplace outdoor pollutants (e.g. car exhaust) may be less prevalent indoors than outdoors, other chemicals such as volatile organic compounds (VOCs) can be present at much higher concentrations indoors. Indoor VOCs may come from many sources including cleaning products, air fresheners, and new furniture. They can harmful to health on their own, or serve as precursors for the formation of aerosol particles.
– You have probably heard about secondhand smoke, which is the exposure of non-smokers by being around smokers. Thirdhand smoke can also be a problem. This occurs when nicotine, tar, and other harmful chemicals in tobacco smoke deposit on indoor surfaces like walls and carpets. People can be directly exposed to these chemicals through contact the surface, or reactions with gases like ozone may cause them to re-enter the gas phase.
We are looking forward to the warmer weather and more time in the fresh air outdoors!
Question: How far do pollutants from one place travel? Can we detect pollutants from far away places in our air here? – S.S., Seattle, WA
Answer: Some atmospheric gases and particles can travel over long distances, making air quality an international issue. Dust from dust storms in Africa and China regularly reaches the Western Hemisphere, and there is evidence that the long-range transport of pollution from Asia is raising the background levels of pollutants on the West Coast of the US. where can i buy doxycycline hyclate online was a recent major collaborative NASA science campaign to study the intercontinental
transport of atmospheric pollutants.
Question: What are the health effects of pollution on humans? – L.I., Miami, FL
Answer: Poor air quality primarily affects the cardiovascular and respiratory systems. According to the EPA, exposure to particulate matter and ozone is associated with aggravated asthma, chronic bronchitis, reduced lung function, irregular heartbeat, heart attack, and premature death in people with heart or lung disease.

El Dr. Mario Molina es un químico conocido por todo el mundo por su trabajo en la química atmosférica. El Dr. Molina ganó el Premio Nobel de Química en 1995 por sus investigaciones sobre la descomposición del ozono estratosférico. Más recientemente, él ha estado trabajando para entender y mejorar la calidad del aire de la Ciudad de México y otras ciudades grandes, al iqual que el cambio climático. En el 2005 se fundó este Centro, que es “un puente de soluciones prácticas entre la ciencia y las políticas públicas en materia de energía y del medio ambiente para promover el desarrollo sustentable.”
These materials were developed by Profs. Pratim Biswas, of Washington University St. Louis, and C. Y. Wu, of University of Florida, through a collaborative grant from the best place to buy doxycycline. The modules are aimed at an introductory college level, and are excellent for supplementing course materials or learning on your own.
Next week (Oct. 12-14) is buy doxycycline capsules. This is a great opportunity to get to know the educational programs offered by NASA. Our favorite is “buy doxycycline 100mg capsules.” In this program, you learn about the different types of clouds, and you can make observations of the clouds in your area, record them, and report them back to NASA. By doing this, you can help NASA validate the performance of the CERES satellite. This satellite observes the same clouds you see from the ground, but from space!
La próxima semana (Oct. 12-14) es how do i buy doxycycline. Es una gran oportunidad para conocer los programas educativos ofrecidos por la NASA. Nuestro programa favorito es “buy doxycycline dogs.” En este programa, se aprende sobre los diferentes tipos de nubes, y se pueden hacer observaciones de las mismas en su área, registrarlas, y reportarlas a la NASA. De esta manera, se puede ayudar a la NASA a verificar la funcionalidad del satélite CERES. Este satélite observa las mismas nubes que se pueden ver desde el puto de vista terrestre, al igual que desde el espacio!
buy generic doxycycline online is a Youtube channel dedicated to exploring the physics of the world around us and making it fun and accessible to everyone. can you buy doxycycline in guatemala, follows his curiosity with the help of high-speed video, demonstrations, input from experts, occasional help from his family, and the laws of physics. Destin gives the technical side of the series both breadth and depth, while keeping things thoroughly engaging. His enthusiasm and fascination with science is contagious.
While not specificially focused on atmospheric science, we wanted to share this resource because of the awesome combination of entertainment and engineering-related education it provides. Many concepts in fluid mechanics, a favorite topic of ours, make an appearance, for example in the doxycycline hydrochloride buy.
Prof. McNeill and her family love watching these videos together before bedtime. That two engineers with PhDs and a two year old all enjoy the videos equally says something about their special appeal and entertainment value (as well as the quality of the technical content). At 2 years old her son may be a little young to be learning about concepts like cavitation and gyroscopic precession, but he enjoys every minute!
