The city of Biloxi, Miss., will sponsor a study of the impact of growth on Keesler Air Force Base that will be funded through a $214,000 grant from DOD’s Office of Economic Adjustment, Sen. Thad Cochran (R-Miss.) announced Thursday.The Mississippi Development Authority is providing $23,000 in matching funds for the joint land use study, which will identify ways to limit development that is incompatible with the mission of Keesler. The 24-month study will consider issues such as height, density, encroachment, noise abatement and other factors that could interfere with activities at the installation.The Gulf Regional Planning Commission will oversee the study; other participants include the city of D’Iberville and Harrison County. The commission plans to request proposals from qualified planners in November, reported the Sun Herald. Dan Cohen AUTHOR
A team of Bangladesh Army has detained seven members of Detective Branch of police, accused of collecting ransom after kidnapping a businessman in Teknaf upazila of Cox’s Bazar.The army detained the detectives with Tk 1.7 million cash on Wednesday morning.Major Nazim Ahmed of Sabrang Relief Centre at Teknaf led the army team that detained the DB men.Major Nazim said the DB team abducted businessman Abdul Gafur from Cox’s Bazar on Tuesday and demanded Tk 5 million as ransom.His family members in the end agreed to pay Tk 1.7 million for his release. After receiving the money, the detectives freed him in Marine Drive area of Cox’s Bazar.Informed by the victim’s family, the army team halted a DB police’s vehicle at an army check-post in Lambari area of the Cox’s Bazar Marine Drive.Maj Nazim said a sub-inspector managed to flee the scene, but others were caught red-handed.The detectives were taken to Sabrang army camp in the early hours of Wednesday.He said, later, the Cox’s Bazar district police superintendent and the additional police superintendent took the detainees from the army camp.The police supers said the authorities would take departmental action against the accused, he added.Officials at the police headquarters in Dhaka said the detained members of the DB are now in police custody.Afruzul Haque, the additional superintendent of police in Cox’s Bazar, could not be reached after repeated attempts for a comment on the issue.Later in the day, the authorities suspended the seven members of DB policeAdditional superintendent of Cox’s Bazar police Afruzul Haq Tutul told Prothom Alo that departmental action will be taken against the suspended detectives.

DOI: 10.1073/pnas.1804353115AbstractUsing data from rural monitoring sites across the contiguous United States, we evaluated fine particulate matter (PM2.5) trends for 1988–2016. We calculate trends in the policy-relevant 98th quantile of PM2.5 using Quantile Regression. We use Kriging and Gaussian Geostatistical Simulations to interpolate trends between observed data points. Overall, we found positive trends in 98th quantile PM2.5 at sites within the Northwest United States (average 0.21 ± 0.12 µg·m−3·y−1; ±95% confidence interval). This was in contrast with sites throughout the rest of country, which showed a negative trend in 98th quantile PM2.5, likely due to reductions in anthropogenic emissions (average −0.66 ± 0.10 µg·m−3·y−1). The positive trend in 98th quantile PM2.5 is due to wildfire activity and was supported by positive trends in total carbon and no trend in sulfate across the Northwest. We also evaluated daily moderate resolution imaging spectroradiometer (MODIS) aerosol optical depth (AOD) for 2002–2017 throughout the United States to compare with ground-based trends. For both Interagency Monitoring of Protected Visual Environments (IMPROVE) PM2.5 and MODIS AOD datasets, we found positive 98th quantile trends in the Northwest (1.77 ± 0.68% and 2.12 ± 0.81% per year, respectively) through 2016. The trend in Northwest AOD is even greater if data for the high-fire year of 2017 are included. These results indicate a decrease in PM2.5 over most of the country but a positive trend in the 98th quantile PM2.5 across the Northwest due to wildfires. Journal information: Proceedings of the National Academy of Sciences Citation: Increase in wildfires causing bad air days in US Northwest to get worse over the past 28 years (2018, July 17) retrieved 18 August 2019 from https://phys.org/news/2018-07-wildfires-bad-air-days-northwest.html Over the past quarter-century, wildfires (unplanned fires burning in forests or other areas) in many parts of the western United States have become larger and longer-lasting than they were in earlier years. Many environmental scientists have suggested this is due to global warming. Prior research has shown that such fires carry fine particulate matter into the air, and that many people can be harmed by breathing such particles. Those with lung conditions such as COPD or asthma, for example, can suffer problems when exposed to such particles, as can senior citizens and children. In this new effort, McClure and Jaffe looked into the possible impacts of bigger and longer-burning wildfires on people living in impacted areas.They obtained data from 100 rural air quality monitoring sites from across the country and sifted through the data, collecting information only on particles that were smaller than 2.5 micrometers. They entered the data into a mapping application that displayed levels of such particulates across the continental U.S. Next, they set filters to show changes in levels of the fine particulates over the years 1988 to 2016 for only the worst air quality days. Doing so showed that the northwest part of the country has experienced more bad days over the past 28 years, and those bad days have been worsening. In sharp contrast, they found that the rest of the United States experienced better air quality over the same time period. The researchers note that even people who are not normally at risk from wildfire particulates can be harmed if they are exposed to them on a regular basis. And sometimes, levels can be extreme, such as when a fire burns for a long time near a community. This document is subject to copyright.
