In the long term, exposure to polluted air can cause cancer and COPD, or chronic obstructive pulmonary disease. Meanwhile, the FBI is assisting with the shooting investigation.

One thing you might want to ask your office building manager or school representatives is whether the HVAC filtration has been improved. As part of a mandatory five-year review, EPA scientists determined that tightening federal soot standards — from 12 to 9 micrograms of PM2.5 pollution per cubic meter of air — would lower annual deaths by 27%, or 12,150 people a year. Mechanical filters increase in efficiency as particle size gets larger, and due to diffusion and electrostatic attraction, also increase in efficiency as particles get smaller. “We need to dig deeper into the data, but the steady movement of goods could be a reason why Chicago hasn’t seen the air quality improvements other cities have.”. As an added benefit, more outside air is provided per person, which contributes to better overall air quality. Aair filters play a big role in improving indoor air quality. Portable HEPA — high efficiency particulate air — rated air filters remove more than 99 percent of airborne particles regardless of the particle size. You may have noticed there’s not as much traffic in and around Chicago as people stay home during the coronavirus pandemic.

She said to take public transportation or bike instead of driving. During the past decade, scientists at the U.S. EPA have discovered daily spikes of soot pollution near intermodal facilities in Chicago and other cities that far exceed average urban concentrations. It also reduces the number of probable infections that will occur if there is an infected person in the classroom. While you want to increase the amount of outside air that is brought in to the room, you also want to filter the air that is recirculated. Scientists say portable air cleaners (also called air purifiers) with HEPA filtration can remove virus particles that cause COVID-19. And you need everything you have to fight against COVID-19,” said Angela Tin, national senior director of the American Lung Association. Modular containers are still exchanged daily between rail cars and semitrailers at more than a dozen intermodal facilities in the city and suburbs. Denver, Detroit, Los Angeles and St. Louis each saw a 16% decline in the tiny particles of pollution during the first full month of shelter-in-place orders. Average daily soot concentrations in the region declined by only 1% last month compared with April 2019, according to a Chicago Tribune analysis of federal and state monitoring data. Community groups have been pushing the city for years to consider the health dangers when evaluating plans for new freight operations. Ex-Gangster Disciples ‘governor’ now distributing food boxes, not crack cocaine, James Yates once helped run one of Chicago’s most notorious gangs. How to build an anti-racist STEM lab: Tips from a DePaul University scientist. “If your respiratory system — your nose, esophagus, lungs — aren’t healthy, you can’t fight against the pandemic. Gov. New or refurbished engines must be cleaner, but older, dirtier diesel equipment can legally keep operating. In situations where HVAC filters cannot be improved or windows are nonexistent, portable air filters and germicidal ultraviolet light can help. Short-term effects include symptoms like coughing, wheezing, choking, asthma or finding it difficult to breathe. After several aldermen raised questions, Norfolk Southern upgraded switcher locomotives in the Chicago area and committed to replacing most of its diesel-powered equipment with cleaner models. Previous studies support what for now can only be speculated. “You’re taking the virus that might be in the air in the room and blowing it outside. The EPA’s Air Quality Index labels days with a certain level of air pollution “unhealthy for sensitive groups.” These groups include older adults, children and those with heart or lung disease. How can you know whether going back to the office or putting your kids back in classrooms is safe?
