Yes, fresh fruit can be contaminated with a variety of things.
The concern here is that the exterior of the fruits or vegetables could be contaminated with pathogens that will make one ill. Some farmers may fertilize their crops with human or animal waste. Also, water that is used to water and clean the food could be contaminated.
earth's water cycle gives us fresh water. we use this fresh water for our daily consumption. when this water cycle is in danger ,our fresh water source also comes in danger. thus if any disturbances occur in the earth's water cycle ,these disturbances directly or indirectly affect our water supply. for example if an area's water supply depends upon a river's fresh water and if due to acid rain the water of that river gets contaminated then the water supply becomes contaminated and cannot be used.
Fresh water is used for irrigation in Egypt.
if they are naturally used to fresh water
If they do enter the fruits, it could be from contaminated water. A lot of the time pesticides are used in soil and sometimes they are sprayed directly over the soil making the pesticides stay on the surface of your fruit. That is why it is important to wash fruit before eating it
contaminated
salt water freezes at a lower temperature than fresh water so the fresh water gets frozen and not the salt water
87% of the world's fresh water supply is used in agriculture -- mostly to water crops.
In a properly operating nuclear reactor, water used to cool the reactor is not contaminated. This water, called primary coolant, is quite pure. And after shutdown and cooldown, the water has little radiation in it. But if the reactor has some malfunction that overheats the fuel, fuel elements can rupture or melt (a meltdown) and fission products, which are hightly radioactive, can be released into the coolant (the water). The water is then contaminated.
if the salt or other impurities in 'fresh water' will not interfere with the experiment, yes.
Fresh water might run out.
Brackish is the word used to describe a mixture of salt and fresh water.
