pashok25 [27]

Most dietary <u>fats </u>are too large to be assimilated and absorbed into the capillaries but they are otherwise absorbed into the lacteals.

<h3>What are dietary fats?</h3>

Dietary fat is necessary for good health. It offers you strength and aids in the absorption of vitamins by your body. Dietary fat has about twice as much energy per gram as carbs and protein.

In the villi ( an organ in the small intestine) is located the lacteal which is a lymphatic capillary that absorbs and assimilates dietary fats. 

Most nutrients are also absorbed through the blood capillaries, but as for dietary fats and fat-soluble vitamins, they are absorbed by the lacteals.

Answer:

Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.

Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.

Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.

"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."
