Suggestions for revision or reasons for rejection

The authors have significantly revised the manuscript and took into account most of the reviewers’ comments:
- The objective of the manuscript is more clearly explained in both the abstract and the introduction. The aim is to assess the latitudinal effect on dissolved and particulate loads in snow and estimate the atmospheric impact on the element storage and export fluxes in surface water of Western Siberia (Lines 17-19 and 72-73)
- the results were improved by a clearer structure and by adding important HCA statistical analyses. The authors also propose new discussion about the limitation of these statistic approaches in regard to natural processes that may control the fate of the major and trace elements from the snow melt to the lake and the river waters.
- the literature review about similar behavior of elements in the environmental fractions that are analyzed was improved
- the use of EF and its limitations is now discussed from line 281 to line 291. Then, global (upper part of continental Earth Crust) and different local references (soil, peat, moss) are used in this new version of the manuscript.
- The discussion on the origin of atmospheric deposition becomes clearer. The new structure presents the effect of mineralogical substrate, industries and long range transport on the composition of the particulate fractions in the snow.
- Figures were revised accordingly

This new version of the manuscript still represents a substantial contribution to scientific progress within the scope of HESS, regarding the impact of atmospheric deposition in permafrost hydrological systems. The scientific approach and all used methodologies allowed to present results of high scientific quality. The discussion are now well-structured, illustrated by appropriate and concise figures and tables and of great interest to show the potential impact of atmospheric deposition related trace elements in remote ecosystems.

There are still few corrections/changes that the authors should take into account before final publication of this very interesting work:
- Lines 212-218 should be put in the methods to indicate the potential blank contributions. You should also provide the metal content of the acetate cellulose filters that are digested with the sample to estimate the elemental particulate concentrations in snow.
- Lines 303-317: The use of “low mobile” and at the same time “volatile” to characterize the behaviour of Pb is confusing. If Pb is considered as volatile should it not be highly mobile in comparison to other refractory elements? As the term volatile Pb is used in the entire manuscript this specific behaviour should be explained in detail before the discussions.
- Lines 369-370: not agree for Cd, Pb, Sb, Cu and As. Looking at figure, they present a high impact of snow melt water on river for the three latitude zones.
- Lines 394-398: Is it not due to the fact that for these elements, the total concentration in the particulate fraction cannot be correlated to their concentration in dissolved fraction, but should be related to specific labile pools that constitute the mineral fraction? Those latter pools being mainly observed using selective extractions. Especially if most of trace elements are supplied by clay mineral (line 430)?

Short summary

We used a coupled hydrological–hydrochemical approach to assess the impact of snow on river and lake water chemistry across a permafrost gradient in very poorly studied Western Siberia Lowland (WSL), encompassing > 1.5 million km². The riverine springtime fluxes of major and trace element in WSL rivers might be strongly overestimated due to previously unknown input from the snow deposition.
