Abstract

Long-term monitoring data of ambient mercury (Hg) on a global scale to assess its emission, transport, atmospheric chemistry, and deposition processes is vital to understanding the impact of Hg pollution on the environment. The Global Mercury Observation System (GMOS) started in November 2010 with the overall goal to develop a coordinated global observing system to monitor Hg on a global scale, including a large network of ground-based monitoring stations, ad hoc oceanographic cruises and measurement flights in the troposphere and lower stratosphere. To date, more than 40 ground-based monitoring sites constitute the global network covering many regions where little to no observational data were available before GMOS. This work presents atmospheric Hg concentrations recorded worldwide, analyzing Hg measurement results in terms of temporal trends, seasonality and comparability within the network. Major findings highlighted a clear gradient of atmospheric Hg concentrations between the Northern and Southern Hemispheres, confirming that the gradient observed is mostly driven by local and regional sources, which can be anthropogenic, natural or a combination of both. In order to understand the atmospheric cycling and seasonal depositional characteristics of Hg, wet deposition samples were also collected at 17 selected GMOS monitoring sites providing new insight into baseline concentrations of THg concentrations in precipitation particularly in regions, such as the Southern Hemisphere and Tropical areas where wet deposition were never investigated before, opening the way for additional measurements across the GMOS network and new findings in future modeling studies highlighting the need of integrated measurements in ambient air and rainwater samples to improve our understanding of deposition processes and oxidation mechanisms. These new observations in fact, give scientists and modelers some insight into baseline concentrations of Hg concentrations in air and precipitation with the overarching benefit which clearly consists in the advancement of knowledge about Hg processes on global scale.

Abstract

Mercury (Hg) and its compounds have long been known to be toxic to human health and theenvironment1,whilst ozone (O3) is highly relevant to the Earth’s climate, ecosystems and humanhealth2.Measurements of Hg and O3 in alpine environments are pivotal when evaluatingair quality in natural ecosystems as well as when trying to understand regionaland synoptic atmospheric transport regimes and advection of air pollutant to theAlps3.This study is crucial for the evaluation of the Hg exchange processes between soil andatmosphere in a high altitude alpine environment, where increasing Hg snowpack concentrationsoccur during winter time, followed by Hg release to the overlying atmosphere during spring andsummer4 timesnowmelt events. In this context, evaluating the gas phase reaction between elemental mercury andozone5is essential. All the experimental activities were performed at the CNR-IDPA atmosphericobservatory at Col Margherita (CMA) that is located in the Italian southeastern Alps, aUNESCO protected region far from anthropogenic and natural sources of air pollutants(altitude 2543 m a.s.l., 46˚ 22’0.6" N, 11˚ 47’30.9" E). The observatory is equipped with acomplete weather station. Total Gaseous Mercury (TGM) was measured from March toAugust 2018 using a Tekran 2537B (Tekran Inc.), a mercury analyzer that alternately samplesTGM on two gold traps and determines it using cold vapor atomic fluorescence spectrometry(CVAFS). During the same period, near-surface O3 measurements were performed with aThermo 49c UV photometric analyzer (Thermo Corp.), according to WMO/GAW guidelines.For the purpose of the present study, daily and monthly levels of hourly Hg and O3concentrations were assessed. Relationships with meteorological parameters (T, RH, P,WS, WD, solar radiation, snow) were investigated by performing a back trajectoryatmospheric reanalysis using HYSPLIT for the duration of the measurement campaign.The results showed that Hg concentrations increase, on average, from spring tosummer, with some episodes of rapid daytime increase or decrease of atmospheric Hgthat could be related to both the O3 variability and specific weather conditions.
