The level of air pollution today is alarmingly high. For instance, the warnings for air pollution in China are being revised to introduce a new sliding scale for checking the quality of air. This is being implemented only two months after the first time China issued a red alert for air pollution back in December 2015.
Mounting Air Pollution Concerns Around the Globe
In Beijing, the highest alert will now be sounded when the AQI crosses 200 for four consecutive days, 300 for two days, and 500 for a single day. In comparison, the U.S. issues a red alert if the AQI exceeds 200 for three days. In December 2015, schools and outdoor construction was shut down in Beijing due to the high level of harmful gases and particles in the air. Scientists are even stating that the high level of air pollution in the city is causing metabolic dysfunction among citizens.
In the U.S., a team of researchers has deduced that cutting down on the emissions related to transport and energy can ideally prevent 300,000 deaths that might be caused in the country by 2030. The researchers went on to state that the U.S. economy could benefit by nearly US$250 bn annually if these lives were to be saved.
Flue Gas Treatment Systems are More in Demand
The emission of sulfur dioxide from manufacturing and processing industries is extremely harmful to the environment. Sulfur dioxide as a gas can react with the moisture in the air to produce acid rains and fogs. Thus the treatment of flue gases is of utmost importance. Since power generation is the largest perpetrator of sulfur dioxide and other toxic gases, there are a large number of systems and services surrounding this industry that can curtail the gaseous emissions through the treatment of flue gases. North America is the leading generator of power in the world, and therefore holds the highest demand for these systems and services. At the same time, the high costs of implementing such systems is currently too high for developing economies, which is creating a gap in development and utilization of flue gas treatment.
