Particulate matter pollution is known to be a factor in increasing the risk of stroke. In addition, the 2004 American Heart Association scientific statement on "air pollution and cardiovascular disease" concluded that exposure to particulate matter (PM) air pollution contributes to the incidence and mortality of cardiovascular disease.
It seems that the negative health effects of air pollution and particulate matter are also of concern, which is the "risk to brain structure and cognitive function". Long-term exposure may damage brain structure and impair cognitive function, a new study suggests. In addition, PM2.5 pollution was found to have increased by only 2 cubic meters per cubic meter, a range prevalent in metropolitan areas, associated with a higher risk of latent cerebral infarction and smaller brain volume, equivalent to about a year of brain aging.
As air pollution remains a global concern, the health effects of particulate matter pollution are of increasing concern.
Cerebral infarction is an ischemic stroke caused by a blockage of a blood vessel that supplies blood to the brain.In particular, air pollution has been linked to deep brain infarcts that, in addition to interfering with the function of the smallest blood vessels, have been linked to poor memory and cognitive skills, which can lead to asymptomatic strokes.
Particulate matter (PM) is an air pollution term that refers to the mixture of solid and liquid particles found in the air. This pollutant comes in many sizes and can be made up of a variety of materials and chemicals. Particles small enough to be inhaled can have health effects.
Particles smaller than 2.5 microns (PM2.5) in diameter, known as "fine" particles, are considered the most harmful to health. Due to their small size (about the average width of a 30th person's hair), the particles can penetrate deep into the lungs.
PM2.5 sensor manufacturer luftmy laser gas sensor ld13 is a high-precision particle concentration sensor based on laser Mie scattering theory, which can continuously collect and calculate particle concentration distribution and output in the form of general digital interface.Ld13 has the characteristics of small size, high precision, strong anti-interference ability, low power consumption, long life and short response time of zero error alarm rate.Ld13 can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particles in the air to provide timely and accurate concentration data.
