Summary
Air pollution, especially particulate matter (PM), significantly increases cardiovascular disease risk and mortality. Understanding PM
Area of Science:
- Environmental Health
- Cardiovascular Science
- Toxicology
Background:
- Air pollution is a complex mixture of gaseous and particulate matter (PM).
- PM air pollution poses significant risks to human health, particularly the cardiovascular system.
- Epidemiological evidence increasingly links PM exposure to cardiovascular morbidity and mortality.
Purpose of the Study:
- To review epidemiological evidence on the cardiovascular effects of PM exposure.
- To discuss the biological mechanisms underlying PM's toxic effects on the cardiovascular system.
- To enhance understanding for preventing and minimizing health impacts of air pollution.
Main Methods:
- Review of epidemiological studies on air pollution and cardiovascular outcomes.
- Analysis of research on the biological mechanisms of PM toxicity.
- Synthesis of current understanding regarding PM's impact on cardiovascular disease.
Main Results:
- Both acute and chronic PM exposure increase the risk of death from cardiovascular diseases.
- PM exposure is linked to ischemic heart disease, heart failure, and stroke.
- PM acts as an endocrine disruptor, contributing to metabolic diseases like obesity and diabetes.
Conclusions:
- Particulate matter air pollution is a critical risk factor for cardiovascular diseases.
- Further research into PM's toxicological mechanisms is essential for public health.
- Air pollution represents a growing global health challenge with escalating mortality rates.

389
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...

02:49Classifying Matter by State
103.3K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

01:13What is Matter?
58.3K
The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...
