Permissible_levels_of_emission_of_gases_in_pollution_check
each gas emitted from pollution are:
nitrogen oxides-5%
fine particulate matter 1%
voc(volatile organic compounds like chloroflourocarbon)-2%
carbon monoxide-0.3%
sulphur dioxide-8%
air toxics:
acroleine-0.01%
formaldehyde-3%
coolants like ozone(o3)-3%
note- might change depending upon your country this is valid for india, Russia, singapore, Malaysia and Sri Lanka. if you are in usa everything is same except fine partilculate matter 5%. according to 2011 conference.

What is the permissible levels of emission of various gases?
Permissible levels of gas emissions vary by region and are regulated by environmental agencies, such as the EPA in the United States. Common pollutants include carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), particulate matter (PM), and volatile organic compounds (VOCs). For instance, the National Ambient Air Quality Standards (NAAQS) set limits for these pollutants to protect public health and the environment. Specific permissible levels can differ significantly based on local regulations and the type of source, such as industrial emissions or vehicle exhaust.
Permissible exposure limits are levels of exposures mandated by?
Permissible exposure limits are levels of exposures permitted by OSHA, the US Occupational Safety and Health Administration.

What are the permissible levels of emission of various gases?
Permissible levels of gas emissions vary by country and are often regulated by environmental agencies. For example, the U.S. Environmental Protection Agency (EPA) sets National Ambient Air Quality Standards (NAAQS) for pollutants like sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, and particulate matter. These levels are based on health and environmental impact assessments. Compliance with these standards is essential to protect public health and the environment.
Permissible exposure limits are levels of exposure mandated by?
OSHA
Why don't pollutants build up as you go up trophic levels?
Pollutants often bioaccumulate in organisms at lower trophic levels, but they can also become diluted as they move up the food chain. While some pollutants, particularly persistent organic pollutants, can biomagnify and increase in concentration at higher trophic levels, this is not the case for all pollutants. Additionally, energy transfer between trophic levels is inefficient, leading to fewer organisms at higher levels, which can limit the overall concentration of pollutants. Environmental processes, such as degradation and dilution, also help mitigate pollutant accumulation at higher trophic levels.
What agency mandates the levels of exposure called Permissible Exposure Limits?
Permissible Exposure Limits (PELs) are maximum permitted exposure levels established by the US Occupational Safety and Health Administration (OSHA).
How can lichen measure the levels of pollutants in the ecosytem?
Lichen are sensitive to pollutants such as sulfur dioxide and heavy metals in the air. They exhibit various forms of discoloration or damage when exposed to high levels of pollutants, making them useful bioindicators for assessing air quality in an ecosystem. By monitoring the health and composition of lichen populations, scientists can infer the levels of pollutants present in the environment.
What organization mandates Permissible Exposure Limits?
Permissible Exposure Limits (PELs) are maximum permitted exposure levels established by the US Occupational Safety and Health Administration (OSHA).
Is it permissible in Islam to pray early"?
Yes, it is permissible in Islam to pray early as long as it is within the prescribed times for each prayer.
An accumulation of pollutants at successive levels of the food chain is called?
Bioaccumulation. This occurs when pollutants are consumed by organisms at lower trophic levels and then get stored in their tissues. As these organisms are consumed by predators, the pollutants accumulate in higher concentrations in their tissues, posing a greater risk to organisms at the top of the food chain.
