2.5 g of Nacl is to be dissolve in 100ml of water gives 10ppm of Na solution.
costly equipment and more expenaive chemicals.the turbidity should be below 10ppm.
You add water to NaNO3 or NaNo3 to water until you reach the desired concentration
Your body can handle 10ppm (parts per million) for 8 hours. After that you are "hs2 saturated" and you body can't fight it a tenth as well. So to answer your question anything over 10ppm, or anything after 10ppm at 8 hours exposure.
DDT is not soluble in water.
