Insights

Exposure to fine particulate matter 2.5 (PM2.5) is linked to increased oral cancer risk in Taiwanese men. Higher PM2.5 concentrations correlated with a greater likelihood of developing oral cancer.

Area of Science:

  • Environmental Health
  • Oncology
  • Epidemiology

Background:

  • Air pollution, specifically fine particulate matter 2.5 (PM2.5), is a growing global health concern.
  • Previous research suggests links between air pollutants and various cancers, but specific associations with oral cancer require further investigation.

Purpose of the Study:

  • To investigate the association between exposure to fine particulate matter 2.5 (PM2.5) and the risk of oral cancer among Taiwanese men.
  • To quantify the risk of oral cancer associated with different levels of PM2.5 exposure.

Main Methods:

  • Utilized linked data from the Taiwan Cancer Registry, Adult Preventive Medical Services Database, National Health Insurance Research Database, and Air Quality Monitoring Database.
  • Included 482,659 Taiwanese men aged 40+ years, assessing PM2.5 concentrations in 2009.
  • Employed logistic regression to analyze the association between PM2.5 levels and oral cancer diagnoses from 2012-2013, adjusting for confounders.

Main Results:

  • An increased risk of oral cancer was observed in men exposed to higher concentrations of PM2.5.
  • Specifically, an odds ratio (OR) of 1.43 (95% CI 1.17 to 1.74) was found for PM2.5 concentrations ≥40.37 µg/m³ compared to the lowest quartile (<26.74 µg/m³).

Conclusions:

  • Higher exposure to fine particulate matter 2.5 (PM2.5) is associated with an elevated risk of oral cancer in Taiwanese men.
  • These findings highlight the potential impact of air quality on oral cancer incidence and underscore the need for pollution control measures.

Classifying Matter by State02:49

Classifying Matter by State

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. 
A mixture is composed of two or...

What is Matter?01:13

What is Matter?

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...

The Atomic Theory of Matter02:59

The Atomic Theory of Matter

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...

Fineness of Cement01:15

Fineness of Cement

The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.
