Particulate matter health effects

Environmental impact of the coal industry Size, shape and solubility matter[ edit ] The size of the particle is a main determinant of where in the respiratory tract the particle will come to rest when inhaled.

Emissions data are compiled from many different organizations, including industry and state, tribal and local agencies. Some emissions data are based on actual measurements while others are estimates. For more information, please visit the Air Emissions Inventories website link will open in a new tab.

People at greater risk for experiencing air pollution-related health effects may, depending on the pollutant, include older adults, children and those with heart and respiratory diseases — second Healthy Heart video link will open in a new tab.

Ozone O3 Health Effects Ozone exposure reduces lung function and causes respiratory symptoms, such as coughing and shortness of breath.

Ozone exposure also aggravates asthma and lung diseases such as emphysema leading to increased medication use, hospital admissions, and emergency department visits.

Exposure to ozone may also increase the risk of premature mortality from respiratory causes. Short-term exposure to ozone is also associated with increased total non-accidental mortality, which includes deaths from respiratory causes.

Environmental Effects Ozone damages vegetation by injuring leaves, reducing photosynthesis, impairing reproduction and growth and decreasing crop yields.

Ozone damage to plants may alter ecosystem structure, reduce biodiversity and decrease plant uptake of CO2. Ozone is also a greenhouse gas that contributes to the warming of the atmosphere.

These effects can result in emergency department visits, hospitalizations and, in some cases, premature death. PM exposures are also linked to harmful respiratory effects, including asthma attacks.

Environmental Effects Fine particles PM2. PM can also be carried over long distances by wind and settle on soils or surface waters.

The effects of settling include: PM can stain and damage stone and other materials, including culturally important objects such as statues and monuments. For those with heart disease, this can result in chest pain and other symptoms leading to hospital admissions and emergency department visits.

Environmental Effects Emissions of CO contribute to the formation of CO2 and ozone, greenhouse gases that warm the atmosphere.

Lead Pb Health Effects Depending on the level of exposure, lead may harm the developing nervous system of children, resulting in lower IQs, learning deficits and behavioral problems.

Longer-term exposure to higher levels of lead may contribute to cardiovascular effects, such as high blood pressure and heart disease in adults. Environmental Effects Elevated amounts of lead accumulated in soils and fresh water bodies can result in decreased growth and reproductive rates in plants and animals.Particulate matter, as specified by US EPA procedures, Reviews of the existing body of research completed in by the Health Effects Institute [] and in by several organizations including the Swiss Tropical and Public Health Institute [][].

Due to the highly toxic health effects of particulate matter, most governments have created regulations both for the emissions allowed from certain types of pollution sources (motor vehicles, industrial emissions etc.) and for the ambient concentration of particulates.

Particulate matter health effects

Fine particulate matter is more hazardous than coarse particulate matter in terms of mortality and cardiovascular and respiratory outcomes. Understanding of the biological mechanisms by which PM leads to health effects is incomplete.

Ambient particulate matter is responsible for harmful effects on health, even in the absence of other air pollutants. Both fine and coarse particles have been shown to affect health, in particular the respiratory system. Particulate matter (PM), also known as particle pollution, is a complex mixture of extremely small particles and liquid droplets that get into the air.

Once inhaled, these particles can affect the heart and lungs and cause serious health effects.

Particulate Matter (PM) Pollution

Jul 19,  · Particulate matter (PM). One type of particulate matter is the soot seen in vehicle exhaust. One type of particulate matter is the soot seen in vehicle exhaust. Fine particles — less than one-tenth the diameter of a human hair — pose a serious threat to human health, as they can penetrate deep into the lungs.
