All of the options you provided are valid ways that advancements in technology improve humans' ability to measure air quality and protect human health. Here's a brief explanation for each:
-
New technologies enable natural and human-made pollution sources to be located and monitored. – This allows for real-time tracking of pollution sources, leading to more targeted interventions.
-
New technologies allow governments to make informed decisions about the regulation of pollution. – Improved data and monitoring capabilities empower regulatory bodies to create and enforce effective environmental policies.
-
Air quality data gathered by new instruments can be used to reduce exposure to pollutants. – By identifying areas of high pollution, measures can be taken to protect vulnerable populations, such as issuing health advisories or implementing pollution control strategies.
-
Air quality data gathered by new instruments can be used to predict trends in pollution over time. – Analyzing historical and current data helps forecast future air quality scenarios, which can guide policy development and public health initiatives.
All these advancements contribute significantly to both measuring air quality and enhancing public health protection.
