Determining the origin of pollution can be challenging due to various factors such as the dispersion of pollutants by wind and water currents, which can carry contaminants far from their source. Additionally, multiple potential sources in a given area may contribute to a cumulative pollution effect, complicating pinpointing the exact origin. Furthermore, pollutants may degrade or transform over time, making it harder to trace their origins through environmental sampling and analysis.
Groundwater is difficult to clean because, the water is dispersed throughout large areas of rock, and also because the pollutants can cling to the materials that make up the aquifer.
All pollution is not the same - sheer tonnage can be balanced against impact (dust vs. hydrogen sulfide) and make comparison of pollution sources, importance and impact difficult or impossible to compare.
It is most difficult to locate the location of sounds directly above the head or below the chin. This is because the ears are located on the sides of the head, making it challenging to discern vertical directionality.
the pollution that factory make s is air pollution
How pollution can be minimized
We cannot make air pollution free. But we can reduce it by taking necessary steps. IF we want to make air pollution free our technology development should be curtailed but we can reduce it..
No If you count pollution as unwanted chemicals or material in an environment.
They do as much pollution as much the locals do.
NO
we can make people aware of harms of water pollution.
No. It would take energy (pollution) to make them. And also to charge them, assuming you went electric.
All constellations that can be seen from the northern hemisphere can be seen - in theory - in Mexico City. In reality, weather conditions and "light pollution" make such sightings very difficult, if not impossible.
