“…DC) is a plant of the genus Baccharis represented by more than 400 species (32). Recent studies have shown antisecretory, anti-inflammatory and antioxidant properties, attributed to the presence of diterpene compounds such as phytochemicals, flavonoids and phenolic acids (33). According to Pocá (34), the anti-inflammatory, antiulcer and analgesic activities are attributed mainly to the presence of saponins and tannins present in their composition.…”

The behavior of the gorse extract has been investigated as a new corrosion inhibitor by weight-loss measurements, potentiodynamic polarization curves, electrochemical impedance spectroscopy and scanning electron microscopy. Weight-loss measurements showed an increase in inhibition efficiency (IE) with the immersion time and the concentration of the extract. At 800 mg L −1 , the extract IE ranged from 72.5% to 93.8% for 2 and 48 h, respectively. The E a decreased slightly with the addition of the extract, characterizing the chemical adsorption by the molecules present in the extract on the surface. The measurements of electrochemical impedance spectroscopy showed an increase in R ct and a decrease in C dl , reaching 96.6% of IE at 1600 mg L −1. The polarization curves indicated that the gorse extract served as an adsorption inhibitor, reducing both the anodic and cathodic current density. The high-molecular-weight fraction isolated from the gorse extract also showed high inhibition efficiencies.

“…The consumption of species that occur in mined areas was also reported in other regions of South America, as well as in the USA, Europe, India, and China [ 1 , 14 , 15 , 17 , 20 , 59 ]. Some of these species have been studied for their potential to bioaccumulate heavy metals, such as Psidium guajava , Morus sp., Baccharis crispa , Baccharis sarothroides , Mentha arvensis , and Cymbopogon flexuosus which bioaccumulate Al, Fe, Si, S, Ca, and Zn [ 36 – 38 , 60 – 62 ]. Location, duration of residence time, and perception of changes in the landscape were the main factors linked to citing more species obtained in contaminated areas.…”

“…However, this restoration process is usually deficient, especially due to the different mining processes employed by mining companies and the lack of inspection of mined areas by responsible authorities, resulting in contamination of the surface layers of the soil with coal residues [31,34]. Some plant species can survive and even thrive in these contaminated sites [35][36][37][38] and can be bioindicators of contamination and useful for bioremediation, if they have bioaccumulation potential [35,37]. Some of these species, however, also have medicinal or food use, and therefore may pose a risk to human health [39].…”

Background: Mining activities have environmental impacts due to sediment movement and contamination of areas and may also pose risks to people's food security. In Brazil, the majority of coal mining activities are in the south, in the Santa Catarina carboniferous region. In this region, previously mined areas contaminated with heavy metals frequently occur nearby inhabited zones. Mining is part of the daily lives of local communities, and its environmental impacts are visible in the landscape; however, plants with medicinal and food use from these areas can be still consumed. Heavy metals are contaminants that do not have odor, color, or taste, and are therefore difficult to detect. We aimed to verify whether people use plants from contaminated mine areas, and understand which factors can influence the use of these resources, even from areas visibly impacted. Methods: We conducted 195 semi-structured interviews with residents from 14 areas nearby abandoned mines in the main municipalities of the Santa Catarina carboniferous region. We asked each interviewee about the length of time they lived in the region, their perception of the quality of the environment, and what plant species were used and for what purpose. We constructed generalized multivariate linear models to verify which variables can affect the group of species mentioned and generalized linear models to verify which variables can affect the total number of citations. We estimated the frequency of citing species collected using the Smith index. Results: From all interviewees, 127 (65%) reported collecting plants for medicinal and food use, directly from contaminated mine areas. Long-term residents, as well as those who noticed more environmental changes (positive and negative), cited more plants used and had more detailed knowledge of plant use in their communities. When asked if they were aware of the possible contamination of mined areas, 85% said they knew about it. However, only 10% associated negative health effects with the use of plant species collected in contaminated mined areas.

“…The different compositions in coal dust as well as its byproducts (e.g. nitrogen dioxide, sulphur dioxide, ash and soot) and waste are considered serious exposure hazards for mine workers due to their mobilization and bioaccumulation in human tissues and toxic effect, which can induce DNA damage in different organisms, indicating the need for biomonitoring (Kabata-Pendias 2000;Menezes et al 2013;Menezes et al 2015). Sufficient proofs have been studied about their relationship with lung diseases.…”

There is a growing concern in mining community about the contribution of nano-particulates to miner’s health. Despite the health influence of respirable dusts and associated lung diseases have been recognized for decades in the mining industry, the nano-scale particulates accompanying with complicated physiochemical properties and their enormous contribution in quantity have been drawing attentions only in recent a few years because of the advancement of nano-science discipline. In this review, we examine the current regulations of dusts exposure and the dominant mass-based monitoring methods to point out the ignorance of nano-particulates in mining industry. The recognized mining-related nano-particulates sources are summarized to identify the mechanically generated finer particulates including particles and aerosols. In addition, the mechanism of adverse health impact on miner with exposure to nano-scale particulates is discussed in a detail to emphasize their substantial detriment as a potential respiratory hazard. Characterization of the complex physiochemical properties of nano-particulates are then summarized and discussed because these properties could be different from regular respirable dusts due to their dramatically increased surface area and particulate counts. The intent of this review is to demonstrate the potential of adverse health effect of nano-particulate on the mine personals throughout the mining cycle and to identify the research gaps of the mine nano-particulate characterization and quantification. We suggest that further understanding of the mining induced nano-particulate properties and their pathogenesis are critical for the future engineering control measure to mitigate the potential health threat for future miners.
