Can't live without being able to breathe good air Last year only ten countries and nine percent of cities in the world would have air of quality judged breathable based on the quantities of ultrafine PM2.5 particulate matter present, considered very harmful to health (it seems to kill more people than any other pollutant in general and in 2021 the guidelines recommended cutting the average from ten to five micrograms per cubic meter); according to the researchers can live on average two months without food, three days without water, but only a few minutes without air which is evidently essential for life. Fine dust enters directly into the bloodstream and then into various organs, can irritate the lungs and respiratory system and reduce the well-being of the body without considering that they are responsible for heart attacks, strokes, tumors, Parkinson's, cause oxidative stress and damage cells at a faster rate than reparative. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 21, 2024

 Particulate matter more harmful for children Children have an organism that has yet to develop and is therefore more susceptible to damage caused by fine particulate matter, then they breathe more frequently and therefore inhale a greater amount of pollutants; at least according to a Thai study that shows that schoolchildren who enjoy better health at school will have better results that they will give back to societies in the future. Thailand has one of the most polluting cities in the world and children would be at great risk of long-term damage to their respiratory system, especially due to PM2.5 particulate matter that is so small that it enters the bloodstream (not to mention that in traffic for example children are closer to car exhausts). Generally children do not understand what happens when they inhale pollutants and simply wonder why their throats burn and cough often. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Mar 13, 2024 n: 5593 Proposals in general to improve air quality in Italy It is difficult to improve air quality in the Po Valley because it is like a basin surrounded by the Alps where fine dust stagnates and tends to accumulate; therefore this phenomenon should be prevented and avoided which makes the air unhealthy and unbreathable, then studies carried out in the past showed that just as when a hole is dug in the sand the grains of the surrounding areas tend to level the hole so it happens for fine particulate matter that tends to move from areas of high concentration to those less saturated with polluting dust. Among the proposals put forward to deal with the situation are, for example, reducing speed on the roads and limiting the circulation of the most polluting cars and vehicles, then avoiding the use of wood and pellet heating, maintaining a lower temperature as well as improving energy efficiency. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Feb 21, 2024 n: 5575 Particulate matter in the Paris metro Particles measuring less than ten micrometers are not visible to the naked eye but they can cause various pathologies from asthma to cardiovascular problems since they easily enter the respiratory tree and are apparently present to a significant extent in the Paris metro network (on average three times more than on the surface) which is one of the oldest in the world. Four million people use this service by exposing themselves to toxic levels of pollutants; in fact, since there is little air exchange in the underground stations the particulate matter tends to bind with metal particles released by the wheel clutches of the metro carriages with the rails and by the brakes, then part of the problem starts from the roads that are above the metro with the particulate matter of car traffic that tends to fall below possibly on waiting passengers. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 30, 2024 n: 5556 The number of smokers is decreasing globally In 2022 about one in five adults in the world smoked, compared to one in three in 2000 generally thanks to initiatives that many countries have taken to decrease the number of smokers; at least according to data provided by international organizations which, however, warn that tobacco manufacturers are developing strategies to reverse this health trend. It is currently estimated that more than eight million people lose their lives each year due to tobacco smoke including one million and three hundred thousand exposed to second-hand smoke; therefore, it would be necessary to try to further reduce the number of smokers and it will take decades to achieve the objectives set by using incisive and convincing campaigns trying to not be manipulated by tobacco producers who would act by interfering with powerful means against health initiatives. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jan 19, 2024 n: 5547 It is useless to buy polluting new clothes Fashion skilfully playing with the colors and lines of the stitching of fabrics leads to the purchase of new clothes that most of the time do not serve to change garments from well-stocked wardrobes, then it is a very polluting industrial chain and when these clothes end up in the environment they are full of toxic substances that threaten biodiversity. Some say that the most sustainable wardrobe is the one we already have, then for new clothes the plastic fibers in which they are often woven by washing them release microplastics into the water and also happens that after wearing them a few times they deteriorate quickly ending up in landfills. A hole in an old dress can be easily repaired and a missing button replaced, then eventually can buy second-hand "vintage" clothes. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Dec 23, 2023 n: 5526 Singapore well adapted to climate change With natural ventilation favored by many trees on the streets, parks and gardens, as well as energy-efficient buildings Singapore would be a metropolis well adapted to climate change thanks to measures supported by the city-state authorities, then some consider it the best in the world for adaptation and a laboratory of cities to imitate. About forty-seven percent of the city that has seen tumultuous development in the past is covered with vegetation that allows a kind of healthy breeze to blow without the use of air conditioners. The six million inhabitants apparently faced without too many problems the record temperature peaks reached this year considering that the city is located near the equator even if the question remains whether this good adaptation can be maintained with greater global warming. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Oct 07, 2023 n: 5462 Consequences of fires on animals A study carried out in Canada would have shown high stress in animals in response to the fires that affected British Columbia, for example, by analyzing the excrement left by animals that reveal high concentrations of cortisol (the stress hormone), the loss of precious fat stores and the reduction of reproductive capacity although further research should be done to understand what the consequences are taking into account the climate change on animal organisms. Planting trees after fires does not mean recovering the habitat of the ecosystem especially if aim at the exploitation of wood, should think in a naturalistic perspective of regeneration as happens after a natural fire and therefore planting trees that favor a return to proper biodiversity. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Sep 26, 2023 n: 5452 Ocean color slightly changed The effects of climate change on life in the oceans would be visible according to the researchers also by their color that apparently would have changed slightly in the last twenty years in more than half of the world's oceans and this is mainly due to changes in the presence of microscopic plankton with consequences on the ecosystem; in fact, from the color can evaluate his state of health. A color that tends to deep blue indicates that there is not much life while if it tends more to green it is the photosynthetic activity of phytoplankton due to the green pigment of chlorophyll that produces the oxygen that we breathe and fundamental for the carbon cycle and therefore of the food chain in the oceans. This could also be useful to monitor the health of ecosystems with instrumental examinations regarding color and identify areas to be protected. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jul 13, 2023 n: 5387 Prevent long and intense heat waves To try to mitigate the devastating effects on the territory of extreme events caused by climate change, urgent action should be taken to prevent them; In fact, it is estimated that there were one hundred and ninety-five thousand victims between 1980 and 2021 from floods, landslides, storms, heat waves and fires as well as huge economic losses. In particular attention in Europe is focused on how to cope with heat waves since the average age of the population advances, therefore with less resistance of organisms to high temperatures and in the summer of 2022 for example there were more victims than usual; then climate models warn that heat waves will be longer, more intense and more frequent. Farmers can grow plants that are better adapted to extreme weather conditions while also seeking appropriate planting days and watering periods. e-mail: info@salutary.eu Tel: +39 338 1809310 Date: Jun 15, 2023 n: 5363 Salutary and Well-being * The author doesn't assume some kind of responsibility for the bad use of the articles councils (all rights are reserved) |
