Consider the following statements with respect to the role of hydroxy...

Most notably hydroxyl radicals are produced from the decomposition of hydroperoxides (ROOH) or, in atmospheric chemistry, by the reaction of excited atomic oxygen with water. It is also an important radical formed in radiation chemistry since it leads to the formation of hydrogen peroxide and oxygen, which can enhance corrosion.
The hydroxyl radical is often referred to as the "detergent" of the troposphere because it reacts with many pollutants, decomposing them through "cracking", often acting as the first step to their removal. In this process, they also aid in killing bacteria or viruses. Hence statement 2 is correct.
The hydroxyl radical, -OH, is the neutral form of the hydroxide ion (OH−). Hydroxyl radicals are highly reactive and consequently short-lived; however, they form an important part of radical chemistry. It also has an important role in eliminating some greenhouse gases like methane and ozone. On a global scale, OH reacts primarily with carbon monoxide (40%) to form carbon dioxide. Around 30% of the OH produced is removed from the atmosphere in reactions with organic compounds and 15% reacts with methane (CH4). The remaining 15% reacts with ozone (O3), hydroperoxy radicals (HO2) and hydrogen gas (H2). Hence statement 1 is correct.
