Coal tar, a powerful but invisible chemical known to cause lung cancer, is expected to make its way into the coal industry this year.
The chemical is found in the coal and is one of the most common causes of cancer and other health problems for coal miners and their families.
But coal tar is also used to make cement, paint, paper and other products.
Coal tar is used as a preservative, an additive, or in other applications to keep things in order.
It’s used to clean up smelly waste in mines and factories.
The National Resources Defense Council has estimated that more than 60 percent of coal mined in the U.S. is produced from coal tar, including some in Kentucky.
It is a chemical that is invisible to the naked eye, but can be seen in the form of fine particles that can be hard to spot.
Dirty coal mines are the fastest growing source of pollution in the United States.
According to the Center for American Progress, the number of coal mines in the country has more than tripled since 2006, and coal companies are expanding their operations.
Coal mining is an industry that uses a lot of coal, as it is a major fuel source for power plants.
A recent study by the environmental group 350.org estimated that between 2010 and 2020, the coal mined from the Appalachian Basin in West Virginia, Tennessee and Kentucky would increase the nation’s carbon emissions by over 1,700 million metric tons.
The coal industry employs more than 8 million people and is responsible for about 70 percent of all greenhouse gas emissions in the nation.
The coal tar chemical is produced by a combination of natural gas and coal.
Gas is extracted from coal seams by pumping gas into the earth.
Natural gas then escapes through the surface, creating the natural gas.
The gas then seeps into the ground and coal seams, producing the chemical.
Coal, on the other hand, is used for manufacturing, refining, processing and transportation.
Coal is also the primary fuel used in the transportation of goods.
It can be found in most vehicles.
Because of its toxic effects, coal tar can be toxic for anyone with respiratory or digestive problems.
It causes bronchitis and asthma in people with asthma and breathing difficulties.
Coal miners can develop bronchiolitis obliterans, which is a lung disease that is linked to chronic lung disease.
The disease can be fatal if not treated quickly.
Coal workers are also at higher risk of lung cancer than the general population.
Coal tar is not the only chemical in coal that’s harmful.
Other contaminants in the mining process are used in many products.
The chemicals used in some coal mining processes can include cadmium, chromium, lead, arsenic, mercury, and other metals.
Asbestos also can be a problem for people who work with the material.
Coal dust and asbestos can cause serious health problems.
People can also become sick from the chemicals used to polish, polish off and heat-treated coal.
Coal industry workers can also inhale toxic dust from coal plants.
These chemicals, combined with the chemicals found in coal, can cause lung and skin irritation, and it can also lead to a wide range of diseases, including lung cancer.
In addition, coal miners who work in mines are exposed to high levels of airborne pollutants from other mines in nearby states.
