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.

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.

Check out this map that shows the number of homes built between 1950 and 1979 by county for year 2000. From the map we can see there were many new homes built in counties within the eastern states, such as New York, New Jersey, Road Island, Main indicated by the darker shading. There were also many new homes built in counties within some western states, such as California and Arizona. We can see states such as North and South Dakota, Nebraska, Montana and Kansas had fewer new homes built within the 29 year period indicated by the yellow/yellowish shading. This makes sense because when compared to the previous map of homes built prior to 1950 for the year of 2000 we see these states had a higher percentage of older homes.

Particulate 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 .
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!
This map on michiganradio.org from February 1st, depicts the results of home lead tests in Flint. The test information, gathered by the State, was then grouped into the following categories to make this map:
- 0 ppb – no lead detected in the drinking water
- 1-4 ppb – the EPA deems this range as acceptable
- 5-14 ppb – exposure is a concern, but still below an EPA “federal action level”
- 15-49 ppb – a range above the federal action level for lead, but can be treated by filters
- 50-149 ppb – reaching dangerous levels, but can be treated by filters
- 150 and above – a range at which the federal government says water filters might not work
Looking at this map, trying to determine the source is difficult because no real pattern can be determined. Makes you think about what other areas in the US have horrible water that either hasn’t been discovered yet, or just taken seriously.
Thanks Michigan Radio for the map! All information from michiganradio.org
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!
