Department of Medical Services, The Neurological Institute reveals microscopic dust or PM2.5, small dust particles that are the most serious threat to Thai people’s health. Nowadays, it has become a national agenda and is considered a public health crisis in Thailand. It affects children, adults and the elderly. Living with risks that will affect every health system, including Diseases of the brain and nervous system
Dr. Weerawut Imsamran, Deputy Director-General of the Department of Medical Services, said that the World Health Organization (WHO) sets the average value of PM 2.5 dust in the air that if it exceeds 25 micrograms per cubic meter (µg/cubic meter), it is considered health hazard While Thailand has determined the danger of PM 2.5 dust to be more than 50 micrograms/cubic meter, nowadays PM 2.5 dust has become a national agenda. and is considered a public health crisis in Thailand Children, adults, the elderly, and all groups of people must risk their lives amidst this toxic dust and smoke. Origina
lly, we may not have thought that PM 2.5 would have any impact on our health because it is so small that it cannot be seen. But because of their small size, microscopic dust can travel to accumulate in the brain. Through at least 3 channels: 1. Through the nasal cavity wall at the interface with the olfactory brain. It will penetrate up to the lower front of the brain. 2. Pass into the lungs. enters the trachea Then absorbed into the bloodstream that flows to the brain. 3. Passes into the digestive tract. By swallowing air that contains microscopic dust particles while talking and absorbing it into the bloodstream. or change the microorganisms and environment in the digestive tract before circulating to the brain
Dr. Thanin Wechachapinan, Director of the Neurology Institute Added that Studies have found that there is actually an accumulation of microscopic dust particles in the brain. especially in the frontal lobe which passes from the nasal cavity wall at the interface with the olfactory brain It will pene
trate up to the lower frontal brain. Because tiny dust particles can be detected in the frontal lobe, similar to diseases that occur in the brain in general. Whether in young children who are in the period of growth It will be found that brain development is slower than that of children who do not receive it. In addition, in the deep brain It was found that new diseases arising from neuro-immune disorders are increasing more and more, corresponding to the time period when there is an increase in microscopic dust. It can be explained that Micro dust has the effect of stimulating inflammatory processes in the central nervous system. And if this effect spreads to the brain that performs other functions, it will result in abnormal brain function in that area, such as causing memory loss, etc. Therefore, people are asked to be careful to protect themselves from microscopic dust. If a high amount of dust is found Outdoor activities should be avoided. Or wear a mask to protect from dust and smoke. In addition, it sh
ould play a role in reducing the creation of micro dust. By reducing the burning Reduce the use of cars with incomplete combustion. and respond to government policy in managing and controlling dust and smoke problems. For the health of ourselves and the public.
