This concentration of 8.5mg/L or 8.5ppm at 25°C is characteristic of well-oxygenated water such as surface water in a clean lake or in a fast-flowing river.

Europe’s water security at risk
Habitat pollution, climate change and overuse of freshwater resources are putting pressure on Europe, with only a third of its surface waters in good condition, the European Environment Agency (EEA) has warned.
EEA executive director Leena Yla-Mononen said on Tuesday, 15 October:
The health of Europe’s waters is not good. Our waters face an unprecedented set of challenges that threatens Europe’s water security.
Only 37% of Europe’s surface water bodies achieved “good” or “high” ecological status, an indicator of the health of water ecosystems, according to the EEA report. Meanwhile, only 29% of surface waters reached “good” chemical status between 2015 and 2021.
77% of Europe’s groundwater reserves, the source of most of the continent’s drinking water, have a “good” chemical status. This status means that the water is free from excessive contamination by chemical nutrients and toxic substances such as PFAS and microplastics.
Surface water is threatened by air pollution, such as coal burning and car emissions, and by agriculture, whose discharged waste pollutes the soil.
European agriculture needs to increase its use of more sustainable organic and agroecological practices, accompanied by incentives and a change in our food and dietary habits.
The European Agency analysed 120,000 surface water bodies and 3.8 million square kilometres (1.5 million square miles) of groundwater sites in 19 EU countries and Norway. The agency called on EEA member states to halve pesticide use by 2030.
We need to redouble our efforts to restore the health of our valued rivers, lakes, coastal waters and other water bodies, and to make sure this vital resource is resilient and secure for generations to come.

Using the sulfur diagram, we can look at two examples of particular environmental situations.
For mine wastes, at a pH of 2.5 and exposed to the atmosphere, so that they are well aerated (pE ~ 15), corresponding to point X on Fig. 10.5, the most important sulfur species in solution would be sulfate. Where the originally mined material was sulfide ore, such as from the copper-nickel ores of Sudbury, Ontario, Canada, sulfur might initially go into someone as sulfide but in oxygenated surface water would eventually (the kinetics are relatively fast) be oxidized to sulfate.
For a swamp or paddy (rice) field where soil containing a high content of organic matter (OM) is submerged, the OM acts as a reducing agent and creates a low pE condition. For example, a submerged soil might have a pH = 6 and pE = -3, corresponding to point Y in the figure. This is near several boundaries, but it would not be surprising to detect the presence of H2S in the interstitial water of the sediment.

One interesting part of the discourse surrounding family-coding relationships in media is when people who are against it raise the argument that two characters ‘can’t be sibling-coded because their relationship is more complicated than that.’ As if siblings relationships by nature were an uncomplicated thing
