The work also defines that geotourism in artisanal mining areas is a significant trend of the last decade, explicitly focusing on the conservation and use of the geological and mining heritage and, in addition, the promotion of sustainable development of ASM. mining artisanal mining small-scale mining environment bibliometric analysis Registry of geological and mining heritage and it
Excerpts
a marked trendgold
This cluster reflects a marked trend of studies focused on the health and environmental effects of mercury or methylmercury contamination in soil, sediments, and water [ 257 , 258 , 259 ].
a clear trendgold
Within these areas, a clear trend of studies related to the implications of ASM from the political, social, economic, and environmental points of view is apparent.
From 2000 to 2018, the overall coverage showed a trend of stable northwest coverage and expansion to the southwest.
Analysis of Spatio-Temporal Pattern As can be seen from Figure 2 , the contribution rate of GASTP in the YRD was generally low and exhibited a decreasing trend with fluctuations.
In addition, when older individuals 65 years and older were stratified into 10-year age brackets, the proportion of older people showed an increasing trend ( Figure A1 ). 3.1.
In high-intensity physical activities, our meta-analysis showed borderline significant lower oxygen saturation and significant higher carbon dioxide partial pressure when using an N95 respirator.
General Model When considering the SEM structural model for the whole sample of employees ( Figure 2 ), both resources (with a negative sign) and demands (with a positive sign) had a highly significant effect on negative acts at the workplace.
As illustrated in Figure 2 b, the elongation at break and tensile strength of the mulch film showed a trend of increasing and then decreasing with the addition of glycerol.
The Ace and Chao indices in fungal community richness showed an increasing trend.
The total soil organic carbon density on the northern slope of Mount Taibai showed a decreasing trend with the increase of the altitude gradient [ 24 ].
With the increase in altitude, soil C:N and C:P showed a decreasing trend in the broad-leaved forest belt and changed to an increasing trend in the coniferous forest belt; N:P first rises and then falls with the increase in altitude gradient [ 25 ].
Although Liyang has gained the honorable title of “National Ecological City”, it still faces many challenges in the ecological environment; the problem of organic matter and soil pollution is gradually increasing; the situation of environmental water protection is serious ( Figure 2 b) and direct drainage of agricultural wastewater is still prominent; and the ecological environment indicates a significant trend of environmental degradation, and fragmentation of ecological space tends to be serious. 2.2.
Second, the participation of farmers in the improvement of the rural settlement environment shows a decreasing trend in the eastern, western, and central regions, in that order.
In terms of quantity change, the area of cultivated land, woodlands, and grassland under this scenario showed a decreasing trend.
In terms of quantity change, the scale of cultivated land showed an increasing trend, increasing by 411.97 km 2 (0.68%) from 2020, mainly because the transfer area of cultivated land to woodland, grassland, and construction land decreased.
In a large study (with a good representative sample size of 10,034) of Canadian children aged 8–12 years, an increasing trend in physical ability scores and knowledge and understanding scores with increasing age was found, with no age differences in motivation and confidence scores [ 31 ].
In functional solidarity, the functional utility of children showed a trend of de-gendering, even daughter endowment, which considering that the utility and value of daughters to the original family have emerged.
A highly significant difference was found in the likelihood of changing the decision in favor of the willingness to undertake CPR for all types of victims, with the greatest difference found in relation to the willingness to conduct resuscitation on strangers (OR = 7.67, 95% CI 5.01–11.73; p < 0.01).
a strong trendgold
However, with the development of the epidemic showing a strong trend of being latent and wide spread, the “reinforcing feedback” from the bureaucratic coordination model on the effect of epidemic prevention and control encounters the “regulatory feedback” that inhibits the growth at the data-driven level.
As seen from Figure 7 b, the spatial distribution of SO 2 coupling contribution in Zhengzhou presents a decreasing trend from central and southeast regions (FAHZU, BI and ZTMLC) to northwest region.
It is noteworthy that there is an increasing trend for the NO 2 pollution in 2016, and the contribution of NO 2 pollutants to the haze cannot be ignored.
The annual change size on the left side of Figure 6 shows that there is a clear gradual increase in the gross gain of built-up land, with the annual change area increasing from 2.2 km 2 (1980–1995) to 16.9 km 2 (2005–2015), while there was an increasing trend in the gross loss of cultivated and forest lands.
The available data indicates an increasing trend for the rate of detection and concentration range of PPCPs in the urban water environments of more and more countries and regions, along with identifications of new variants of PPCPs.
As shown in Figure 5 , in general, the contents of the different particle sizes showed a decreasing trend after the increase in particle size.
