Average Fine Particulate Matter (PM 2.5) (µg/m³) By County (2011)


Check out this map that shows the average fine particulate matter (PM 2.5) (µg/m³) by county for the year 2011. From the map we can see clusters with a higher average indicated by the darker shading. For instance, we can see a cluster consisting counties within for Colorado, Nebraska, Kansas and Wyoming. It is also apparent there are higher concentrations in many Southern, Midwestern and Northeastern states compared to western states. States such as, Indiana, Ohio, Tennessee and Kentucky predominantly have a higher average.

Rate of Self Reported Pesticide Related Illness By State 2014



Today’s map shows the rate of self reported pesticide related illness by state for the year of 2014 per 100,000 person. From the map we can see some states had rates ranging as low as 0.00 to 0.27 indicated by the yellow shading. In contrast some states, such as Alaska, Florida, Alabama, Mississippi, Arkansas, New York, Kansas and Virginia had rates as high as 0.87 to 2.56 indicated by the dark blue shading. However, its important to note that because these are self-reported rates the date is subjected to under-reporting. In addition, because these exposures are self-reported both the type of pesticide and the degree of illness associated with the exposure may be mis-classified since the designation by the poison control center for both is based on the description provided by the caller.

According to the CDC farmworkers are among those when are subjected to pesticide exposure. For more information on migrant workers click here.

Average Daily PM 2.5 By County in 2011

MOTD7_19_17_AvgPM252011Particulate Matter (PM) are small particles that contain microscopic solids and liquid droplets that are suspended in the air which can be inhaled and cause health effects. PM range in size, but particles less than 10 mm present the greatest threat. Some particles are emitted directly from a source such as, smokestacks, fires, construction sites, etc. and others are a result of complex atmospheric reactions [1].

Check out this map that shows the average daily PM 2.5 by county in 2011. From the graph we see a three distinct darkly shaded clusters indicating a high amount of daily exposure. The first cluster includes counties in Nevada and Utah. The second cluster includes counties within Colorado, Wyoming, Kansas and Nebraska. The third and most prominent includes counties within various southern states such as, Mississippi, Alabama, Georgia, Tennessee, Kentucky, Indiana, Illinois, Ohio, Pennsylvania, Virginia, West Virginia and North and South Carolina. In contrast, we can see states such as Oregon, Texas, California and Arizona are shaded yellow indicating a lower daily average.

This interesting webpage displays toxic locations or superfund sites throughout the US based on the year it was discovered, the type of waste, the site’s hazardous ranking score, population size near the site, and race around the location. Brooke Singer and team wanted to show the areas of these superfund sites and provide a map that the community could interact with. Check the site out at www.toxicsites.us

Below is a full view of the US in 2015 and under is zoomed in on New Jersey in the New Brunswick area. Thanks www.toxicsites.us for the interesting map!

Mean PM 2.5 Levels in Air

PM, or particulate matter, are tiny solid or liquid particles found in the atmosphere. Particulate matter is considered the most dangerous form of air pollution as the tiny particles can easily be absorbed by the lungs into the blood stream causing many health issues. The International Agency for Research on Cancer and the World Health Organization both consider particulates to be a Group 1 Carcinogen. PM 2.5 are particulates with a diameter of 2.5 micrometers. PM 2.5 particulates are especially dangerous as their small size allows them to penetrate the lungs more easily. We have taken data from the EPA and created a map that shows the mean PM 2.5 levels across the United States. Check out how clean the air is in your city or state below, and keep checking our site for more maps and data on air and water pollution! Vertices gis consulting community map pm25.png

The Most Distinctive Causes of Death by State, 2001-2010

Screen Shot 2016-03-10 at 12.06.56 PM.png

This map put out by the CDC, shows the most distinctive causes of death in the United States. This map is colored coded to be easier to read and as you can see the key below the map shows what the cause of death is. There are interesting limitations to keep in mind while looking at the map. On the CDC site they explain “A limitation of this map is that it depicts only 1 distinctive cause of death for each state. All of these were significantly higher than the national rate, but there were many others also significantly higher than the national rate that were not mapped. The map is also predisposed to showing rare causes of death — for 22 of the states, the total number of deaths mapped was under 100. Using broader cause-of-death categories or requiring a higher threshold for the number of deaths would result in a different map. These limitations are characteristic of maps generally and are why these maps are best regarded as snapshots and not comprehensive statistical summaries” (cdc.gov). To take a closer look at the map and read the background of the project go to cdc.gov
