“…[40]. However, in the assessment of Hg health risk, soil Hg and atmospheric Hg are usually evaluated separately [41][42][43], or the concentration of atmospheric Hg is determined by regional monitoring [44,45], and thus measurements are not comprehensive or precise enough.…”

Due to the rapid expansion of tourism, mining, and manufacturing, the economy of Hainan Island in southern China has experienced swift growth. However, it also brings the risk of soil pollution by mercury (Hg) as a result of increased traffic and mineral processing activities. In order to investigate the characteristics of soil Hg pollution in Hainan Island and assess the health risk, a total of 239 samples were gathered from five representative regions across the island. The findings indicate considerable fluctuations in the soil Hg concentration across the five sub-study areas, which are influenced by factors such as wind direction, mining activities, and economic development. Changjiang Li Autonomous County, situated in the downwind direction (NW) and rich in mineral resources, shows the highest soil Hg concentration (10.00–1582.50 ng·g−1). Following closely are Haikou and Sanya, the two most economically developed cities on the island, with soil Hg concentrations of 8.33–321.50 ng·g−1 and 6.04–180.50 ng·g−1, respectively. Wuzhishan Nature Reserve and Lingshui Li Autonomous County, located in the upwind area (SE), show the lowest concentrations, ranging between 10.70–104.67 ng·g−1 and 9.43–84.00 ng·g−1, respectively. Both the Single Pollution Index method and the Geo-accumulation Index method were employed to assess the level of Hg pollution. The results indicate that nearly half of the sampling sites are contaminated, in which the proportion of contaminated sites in Sanya and Haikou are the highest, but the level of contamination is low; the heavily contaminated sites are predominantly found in Changjiang Li Autonomous County. However, the low Health Risk Index (HI) ranging from 0.0001 to 0.0334 suggests that although the soil is contaminated with Hg, it does not pose a substantial non-carcinogenic risk to human health.

“…O progresso tecnológico possibilitou o uso de métodos integrados de sensoriamento remoto e sistemas de informações geográficas para analisar o comportamento do Hg em conjunto com diversas características ambientais, como a topografia e o uso e cobertura dos solos (KOCMAN et al, 2011;SCHMID et al, 2013;DAI et al, 2013;BHARDWAJ et al, 2020). Aliado a estas ferramentas, métodos geoestatísticos podem ser utilizados para descrever fontes e pontos críticos de poluição por mercúrio a partir da interpolação de dados (JIANG et al, 2020;SAHAKYAN et al, 2020;WU et al, 2020).…”

A emissão de mercúrio (Hg) por atividades antrópicas tornou-se um processo capaz de modificar o seu ciclo biogeoquímico natural. Os sedimentos são o principal compartimento para a metilação do Hg nos ecossistemas aquáticos, enquanto os solos superficiais são os maiores reservatórios de Hg nos ambientes terrestres. O objetivo deste estudo foi caracterizar as concentrações médias de mercúrio total (HgT) nos sedimentos dos córregos da Estação Ecológica de Águas Emendadas (ESECAE), em conjunto com a distribuição espacial do Hg nos solos superficiais da reserva, analisada a partir de dados secundários. Dados de sensoriamento remoto foram empregados para avaliar a influência da paisagem local nas concentrações médias de HgT. A concentração de mercúrio total (HgT) no sedimento variou de 16,12 a 96,80 ng.g-1, com média de 41,46 ± 28,01 ng.g-1. A avaliação do uso e cobertura do solo demonstrou que as áreas antrópicas são predominantes no entorno da ESECAE. A combinação entre o modelo digital de elevação e os autovetores indicou a orientação do HgT nos solos superficiais em direção às menores altitudes, favorecendo o acúmulo nos córregos. A tendência da distribuição decrescente do HgT de fora para o centro da ESECAE e as maiores concentrações nos córregos marginais às rodovias indicam a influência das atividades humanas desenvolvidas no entorno da área de estudo. Portanto, a combinação das análises espaciais foi eficaz para a determinação da distribuição de mercúrio nos solos superficiais e definição de locais mais vulneráveis à poluição.
