1. Tar is used on roads, and parking lots.
2. Coal tar is a biproduct of coking coal.
3. The scientists that performed this experiment are from austin texas.
4. Tar is toxic to fish.
5. I learned a lot.

Apartments with parking lots treated with the sealcoat.

It contained house dust with much higher concentrations of PAH’s.

There was students from Austin Texas that performed.

Tar has been linked to contaminants.

Coal tar is a byproduct of the coking of coal.

1. Coal-tar is thesubstance that is sparayed on parking lots.
2. Contominated house dust is linked to parking lots.
3. The scientist that performed this interesting study are from the U.S. Geological Survey and is in Austin,Texas.
4. Conciogens are poisions to fish.
5. Sealcoat products are widely used in the U.S.

1 Tar has been linked to contaminants.
2 This includes the water that we drink.
3 The study was done in Austin, Texas.
4 Tar is a product of the coking of coal, and contains about 50 percent or more PAHs by weight.
5 It is toxic to fish and other wildlife.

~ Coal-tar-based sealcoat has been linked to elevated concentrations of the contaminants PAHs in house dust
~ Apartments with adjacent parking lots treated with the coal-tar based sealcoat contained house dust with much higher concentrations of PAHs than apartments next to other types of parking lots
~ Coal tar is a byproduct of the coking of coal, and can contain 50 percent or more PAHs by weight.
~ PAHs are an environmental health issue because several are probable human carcinogens and they are toxic to fish and other aquatic life.
~ Small particles of sealcoat likely are tracked indoors by residents after they walk across the parking lot.

1.Coal-tar-based sealcoat has been linked to elevated concentrations of the contaminants polycyclic aromatic hydrocarbons.

2.This study was conducted in Austin, Texas, by scientists at the USGS.

3.Coal tar is a byproduct of the coking of coal.

4.Small particles of sealcoa are most likely tracked indoors by people after they walk across the parking lot.

5.The sealcoat wears off of the surface of roads quickly, especially in areas of high traffic.

1.The City of Austin, Texas, estimates that before a ban on use of coal-tar-based sealcoat in 2006, about 660,000 gallons of sealcoat was applied every year in the city.

2.These findings represent a breakthrough in our understanding of one of the important sources of these contaminants in house dust and how these contaminants can move from outdoors to indoors

3. Coal tar is a byproduct of the coking of coal.

1. This article is about contaminated house dust linked to parking lots with coal tar sealant.
2. Coal-tar-based sealcoat is the black paint that is sprayed in parking lots.
3.Coal-Tar is used very commonly in U.S.
4. Coal-tar is a black shinny substance.
5. PAH concentration affects house dust.

1.)Black shiny substance painted over most parking lots is seal coat
2.. Tar has been linked to contaminants
3.)Caciogens are poisionis to fish
4.“These findings represent a breakthrough in our understanding of one of the important sources of these contaminants in house dust and how these contaminants can move from outdoors to indoors.In the past, several factors have been thought to affect PAH concentrations in house dust, including tobacco smoking and frequency of vacuuming
5.. Small particles of sealcoat contain extremely high concentrations of PAHs.
