Science AMAs are posted early to give readers a chance to ask questions and vote on the questions of others before the AMA starts.
Guests of /r/science have volunteered to answer questions; please treat them with due respect. Comment rules will be strictly enforced, and uncivil or rude behavior will result in a loss of privileges in /r/science.
If you have scientific expertise, please verify this with our moderators by getting your account flaired with the appropriate title.

If you were able to instantly ban a single process or chemical from being used in order to improve air quality which would it be a why?
Are all perfumes and scented body products the same with regards to environmental impact? If I wanted to be more environmentally ethical in my personal scent choices, is there something I should look for?
What not insignificant source of ground-level pollution do you think would most surprise your average person?
As someone who is launching an environmentally-responsible printing company, what are some key things I can do to reduce my footprint? We're using as much 100% PCW stock as possible and are switching to vegetable-based inks - we also plant a tree for every order placed. I'm not interested in offsetting our footprint alone, but more so in reducing the impact of it as much as possible - am I simply in the wrong industry or is having mindsets like mine important to encouraging a paradigm shift in mentality across the industry?
Thank you in advance! My mother works with Universities across the world in the fields of waste management and environmental impact but her expertise doesn't cover inks, solvents and coatings - mainly heavy metals and biowaste.
Hi, thanks for doing this AMA! My question is: How did you all come to work for NOAA? Any tips for a recent college grad hoping to work there some day? :P
Under the Trump administration, many environmental protection laws are being changed, information about climate change is being scrubbed from the EPA web site, and NASA climate monitoring satellites are being shut down.
In the long term, it would seem that pollution would increase, but information about the affects would be suppressed.
Is it as sinister as it sounds, or are the changes also accepted by the scientific community?
If it is as bad as it appears, what other processes are there to continue to reduce and monitor pollution levels?
Is the US potentially sliding back to post-industrial scale levels of pollution?
Globally we flare and vent over 14 billion cubic feet of gas everyday. Have you looked at the pollution emitted from Gris poor practice to deal with waste gases in the oil and gas industry? VOC's, particulates, HAP's, methane, etc.
Industry is allowed to assume a flare combusts at 98% efficiency but any one that has looked at a black smoky flare would be hard pressed to find that assumption valid. Since methane comprises the majority of the waste gas and is 86x worse than CO2 from a GHG perspective, I believe this is the worlds greatest opportunity to reduce emissions and have a significant impact on air pollution.
In the end, does it actually produce less pollution to drive an electric vehicle given the fossil fuel inputs to generate that electricity?
This may be a little off topic as it's related to ground pollution rather than air pollution:
I recently heard a story on NPR about algal blooms in Lake Erie. New research seems to suggest these aren't related to an increased use of fertilizer but are instead being attributed to new farming techniques that are stirring up an old accumulation of phosphorous in the soil from decades ago (if I understood the story correctly).
Is there any way to prevent this old fertalizer from polluting the water or we do we have to just "push through" decades of previous negligence?
Are there other examples of old pollution causing new issues?
Why do electric car batteries emit more carbon dioxide gas than diesel cars?
Interested in conservation and environmental protection in the D.C. Area. Graduated with a degree in marine biology, and currently working as a long term substitute teacher. What's the best way to break into the field? I keep getting rejected from the jobs I'm really passionate about
Are there any pesticides in use that should currently be replaced by a less harmful one?
This is a little off-topic: What are some techniques that we could use for earth to absorb slightly less heat from the sun?
Is it true when tap water becomes airborne it creates VOCs? Thanks!
Hi! Prof. Chris Cappa (CC) here with Dr.'s Brian McDonald (BM), Jessica Gilman (JG) and Joost deGouw (JdG) ready to go!

Would you recommend not using cologne, hair spray, spray paint?
Thank you for the AMA.
What effect, if any, does airborne pollution have on rain fall. Do pollutants contribute to or interfere with nucleation? Has there been any measurable increase or decrease in rain fall in areas with increasing pollution.
Thank you for doing an AMA!
Is there a significant difference in pollution amounts from paints applied via a sprayer versus a brush or roller? Are there types of paint that are safer to use than others? Painting is a significant part of my job, so I want to know how I can minimize my impact.
