Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
This is a list of bodies of water by salinity that is limited to natural bodies of water that have a stable salinity above 0.05%, at or below which water is considered fresh.
A regional distribution of the 3,230,000 km 2 of saline land worldwide is shown in salt affected area based on the FAO/UNESCO Soil Map of the World. Additionally, in areas where sprinkler irrigation is practiced, salty sprinkler water can cause considerable damage by leaf burning, whether the soil is saline or not.
These concentrations are obtained with intensive daily drip irrigations of 10 or more mm (i.e. more than 10 liter per m 2 per day) with water having a salt concentration expressed in electric conductivity (EC) of 2, 4, 8, 12, 16, 20 and 35 dS/m. [3]
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Likewise, large algal blooms can cause biodilution to occur, which is a decrease in the concentration of a pollutant with an increase in trophic level. This is opposed to biomagnification and is due to a decreased concentration from increased algal uptake.

Quantitative comparison of rank abundance curves of different communities can be done using RADanalysis package in R.This package uses the max rank normalization method [1] in which a rank abundance distribution is made by normalization of rank abundance curves of communities to the same number of ranks and then normalize the relative abundances to one.
