Question

Очень нужно what's wrong with aerosols?​

Answer 1

Ответ:

Many people associate aerosol sprays with damaging the ozone layer. ... Every time you spritz an aerosol, you raise your carbon footprint because they contain hydrocarbon and compressed gasses. In fact, today's CFC-free aerosols also emit VOCs that contribute to ground-level ozone levels, a key cog in asthma-inducing smog.

Многие люди связывают аэрозольные аэрозоли с повреждением озонового слоя. ... Каждый раз, когда вы распыляете аэрозоль, вы увеличиваете свой углеродный след, потому что они содержат углеводороды и сжатые газы. Фактически, сегодняшние аэрозоли, не содержащие ХФУ, также выделяют Лос, которые способствуют повышению уровня приземного озона, ключевого винтика в вызывающем астму смоге.

Answer 2

Aerosols can refer to a few different things, so I'll cover a couple of potential interpretations of your question:

1. Environmental Concerns - Aerosol Propellants and Climate Change: Aerosols are tiny solid or liquid particles suspended in a gas, like the particles in air fresheners, deodorants, or hairsprays. Historically, some aerosol products used chlorofluorocarbons (CFCs) as propellants. CFCs were found to be harmful to the ozone layer, which protects Earth from harmful ultraviolet (UV) radiation. The Montreal Protocol, an international environmental agreement, led to the phasing out of CFCs in aerosol products.

   Today, aerosol propellants are generally safer for the ozone layer, but there are still concerns about their impact on climate change. Some hydrocarbon-based aerosols can contribute to the greenhouse effect by releasing volatile organic compounds (VOCs) that can react with other pollutants and form ground-level ozone, which is a potent greenhouse gas.

2. Health Concerns - Inhalable Aerosol Particles: Aerosol particles in the air can be harmful if inhaled. Particles from sources like vehicle exhaust, industrial processes, and burning fossil fuels can contribute to air pollution and have negative effects on human health. Fine particulate matter (PM2.5), which is made up of tiny particles less than 2.5 micrometers in diameter, can penetrate deep into the respiratory system and even enter the bloodstream, leading to a range of health issues, including respiratory and cardiovascular problems.

3. COVID-19 and Respiratory Transmission: In the context of the COVID-19 pandemic, aerosols have been implicated in the transmission of the virus. When an infected person coughs, sneezes, talks, or breathes, respiratory droplets containing the virus can become aerosolized and remain suspended in the air for a period of time. If these aerosols are inhaled by others, it can lead to the spread of the virus. This realization has led to recommendations for improved indoor ventilation, mask-wearing, and other preventive measures.

Overall, aerosols themselves are not inherently "wrong," but there can be concerns associated with their environmental impact, contribution to air pollution, and role in the spread of diseases. It's important to understand and address these concerns through responsible usage, regulation, and mitigation efforts.
