Current Question (ID: 17865)

Question:

$\text{The most abundant hydrocarbon pollutant is:}$ $1. \text{Methane}$ $2. \text{Ethane}$ $3. \text{Propane}$ $4. \text{Butane}$

Options:

1. $\text{Methane}$
2. $\text{Ethane}$
3. $\text{Propane}$
4. $\text{Butane}$

Solution:

$\text{HINT: CH}_4 \text{ is the most abundant hydrocarbon pollutant.}$ $\text{Explanation:}$ $\text{Pollutants are the contaminants that get introduced into the natural environment, beyond permitted limits and cause deleterious effects to the inhabitants in a visible way.}$ $\text{A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values.}$ $\text{Methane (CH}_4\text{), the simplest hydrocarbon, is the most abundant hydrocarbon pollutant.}$ $\text{Methane is a powerful greenhouse gas emitted by human activities such as leakage from natural gas systems and the raising of livestock, as well as by natural sources such as wetlands.}$ $\text{Methane is a short-lived climate pollutant with an atmospheric lifetime of around 12 years.}$
