pollutants in the water
Pollutants dumped into the air can eventually get into your body when you eat, drink and breathe. Pollutants in the air fall to earth with the rain drops and snow flakes. The pollutants then become more and more concentrated by biomagnification as they move up the food chain to you.
A pure luck?
natural deposits of coal and iron.
The air becomes stiller, hence the air becomes murky because dust and pollutants are no longer lifted from the surface. This can become a problem in cities where many pollutants exist. During a severe inversion, trapped air pollutants form a brownish haze that can cause respiratory problems.
Precipitation: rain, snow, hail, sleet. Some pollutants may cause the precipitation to be chemically active and irritating to living things, in which case it may be called "acid rain."
Unpolluted rain should be neutral but many pollutants are acidic (oxides, dioxides and trioxides of Sulphur and Nitrogen in particular). These can become dissolved in rainwater it cause it to become acidic.
It happens when a beta particle is emitted from the nucleus of the atom of element 92. Beta Particle is emitted when a neutron is converted to a proton.So atomic number that is , the no of protons increases by 1. Hence 92 becomes 93.
After 9 and a half months of 0 withdrawls and 0 deposits
The marker will become dry. There isn't enough solvent emitted from markers to cause any inhalant effect.
The River Yamuna is harmful to animals and humans because it contains sewage and other pollutants. There are also other pollutants like metals that are toxic.
