@cryptopaddy801: Nice.... Get some Zeolite, Bentonite Clay and Borax, it helps to remove heavy metals... Even the small amount, over time it will accumulate and thats not good, you need to remove them asap, also if you in area when they heavy spray the air, you get them with air... Zeolite is really good, specially if you mix it with Bentonite clay.... Have a think about it.... Peace and Love! In Lak'ech!
