	Sulfur has 23 known isotopes, however, only four of them are stable. The stable isotopes of sulfur are: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%).

−	*While sulfates are the main focus of much of the literature I read, almost all volatile organic compounds are considered to be air pollutants, at least in the United States.
−	*Some of the volatile organic compounds defined as air pollutants by the EPA include: benzene, chlorine, ethylene glycol, hexane, HCl, methanol, toluene, and xylenes, among many others.
−	*I hope to shift my focus of air sampling from sulfates to a broader variety of VOCs, due to the complications involving the air sampling of sulfates as well as the low availability of standards.
−	*25ug/mL suggested for gcms standards

+The natural passageway of sulfur to the atmosphere is through sea spray. However, the primary anthropogenic cause of sulfur in the atmosphere is the burning of fossil fuels. When this sulfur is released into the atmosphere, it reacts with water to create sulfuric acid. This causes the pH of the water droplets in rain to become more acidic than usual and can damage natural systems.
