As health groups have raised awareness of the dangers of lead paint, more and more homeowners have safely removed these paints from their homes. This reduces the amount of children who come in contact with this lead paint and may eat it, causing a downward trend in amount of children with more than 10 micrograms of lead in their blood stream from 1997-2015
Thank you for taking the time to put together these videos. Students find them very helpful both they and I appreciate your efforts. Unfortunately, at 15:16 in this video you give advice that is just flat out dangerous. Lead paint abatement, like asbestos abatement should only be done by professionals. Under no circumstances should you use a vacuum cleaner to vacuum up lead paint dust as it will result in some of the dust becoming airborne, which is a severe health hazard. Generally, lead paint is found throughout a housing unit and abatement or even RRP requires specialized techniques that go beyond the skills of most contractors, never mind most renters (this is more of a problem in rental stock) or homeowners. Because this is mostly an issue in lower cost rental housing, the impacts of lead paint can have a disproportionate impact on social justice communities. (See for example Harriet Washington's discussion of the KKI/Johns Hopkins Lead abatement experiment starting on p62 of "A Terrible Thing to Waste") While I am picking nits about lead, I have two other observations. Lead does not get into the water supply from flaking of or being scraped off as described at 14:30. Lead leaches out of pipes and or lead based solder when water is acidic or has low mineral content. The cause of the issues in Flint was that the city switched water sources from the Detroit Water and Sewage to the Flint River. The water chemistry of the river was different and the Flint River water did not receive appropriate water treatment. Finally, another source of airborne lead is soil contaminated with tetraethyllead. Prior to 1996 tetraethyllead was added to gasoline to prevent preignition (exploding before the spark plug fires) this resulted in soil contamination next to major roadways. Even today, when dust from contaminated soil becomes airborne, TEL can become airborne too. This tends to have the most impact on communities sited next to major highways...
I doubt he was reffering to the home owner, and instead to a professional. By you, he didn't specifically mean you as the homeowner, he meant people in general, in this case professionals. See 4:05
Hello Mr. I am new to your channel and I am taking APES this year. So far your videos are amazing and I use it. I wanted to ask you do you recommend the AP prep books??
1) 2:22 Developing vs developed countries.
2) 4:08 PM& asbestos
3) 6:46 CO (carbon monoxide)
4) 8:42 VOCs ( volatile organic compounds)
4:08
thank you kind soul
Dude is carrying my grade in apes 😂
Ya

Barron’s is very helpful and easy to follow!!
I hear that fan in the background Smedes...
How come Febreeze is so commonly used if it contains VOCs?
cuz it smells good
I enjoy the thumbnail
Oh, man. This was the very first thumbnail I ever made haha. Hopefully they've gotten a little better since then, but thank you!
1) 10:36 Radon gas.
2) 13: 26 Dust and mold
3) 15:38 Lead.

Imagine having an electric air freshener. Ridiculous
