“…These waters are able to greatly accelerate the processes of bio-oxygenation but, on the contrary, the limited scope of the rivers does not allow a proper dilution of the contribution of micro-organisms or of those pollutants not felled in the process of self-purification, as total P, or characterized by slower kinetics of oxidation (N-NH4) (Ben-Dan et al 2001, Warnken and Santschi 2004, Giampaoli et al 2013. These features determine the difference in distribution between values of LIM and LIM eco for each river, as shown in Figure 1.…”

According to the European Water Framework Directive, Italy introduced two aggregate indices for evaluating the ecological status of rivers, called respectively LIM (Pollution Level of the Macro-descriptors) from 2000 to 2008, and LIM eco from 2010 onwards. The LIM index considered the % of Dissolved Oxygen (DO%), ammonium nitrogen (NH 4 -N), nitrate nitrogen (NO 3 -N), total phosphorus (P), Biochemical Oxygen Demand (BOD 5 ), Chemical Oxygen Demand (COD), and Escherichia (E.) coli, while LIM eco considered only DO%, NH 4 -N, NO 3 -N, and total P. The aim of this study was to evaluate differences between LIM and LIM eco for defining quality status of freshwaters. For this purpose, data obtained during an annual monitoring campaign of four main rivers of southern Italy were used to calculate both indices. LIM eco seems to return the quality status of a river better than LIM when the state of the water body is more compromised, while there is a substantial consistency when the river quality is at a medium/high level. Indeed, LIM intended to give a 'traditional' classification of freshwaters, integrating environmental and ecological descriptors, while LIM eco focuses on the trophic status of freshwaters, considering only nutrients and oxygen, essential for the aquatic biological communities and it does not consider organic load and microbiological contamination.

“…The effect may be related to the precipitation of excess iron in the form of insoluble FeS. 35,36 In mammalian cells, there is an endogenous production of H₂S. It is located in iron-sulfur clusters in the mitochondria and readily released when needed.…”
