“…Heavy metals are naturally present in the soil and cannot be degraded, they can remain in the soil and water bodies for a long time, so they will continue to increase over time [12]. The accumulation of metals in the soil can decrease soil microbial activity, soil fertility, overall soil quality, and a decrease in yields and the entry of toxic materials into the food chain [13].…”

Research on the content of heavy metals in cocoa beans from mining and non-mining areas in South Sulawesi has been done. The purpose of this study was to determine the effectiveness of handling cocoa according to SNI 2323-2008 in reducing heavy metal contamination of cocoa beans at mining and non-mining locations. The research method used was a completely randomized factorial design pattern with three replications. The first factor was two-region (mining and non-mining areas), the second factor was various quality handling (GHP and non-GHP). The results showed that the heavy metal analysis of cocoa beans that met the SNI requirements was found in the non-mining areas of Luwu district, both GHP (Pb 0.13 ppm, Cd 0.37 ppm, Cu 1.26 ppm, and Zn 41.72 ppm) and non-mining. GHP (Pb 0.13 ppm, Cd 0.31 ppm, Cu 0.51 ppm, and Zn 37.02 ppm). Meanwhile, cocoa beans in mining areas in East Luwu Regency have not met the SNI requirements because Pb, Cd, and Zn levels exceed the safe limits for the quality requirements of cocoa beans. The best cocoa beans from non-mining with GHP treatment (11.98% fat, total acid 313.25, pH 5.05, crude fiber 13.49%, polyphenols 0.37, and moisture content 7.84%)

“…Its boundary is bounded by the Gulf of Mannar, Pamban Island, Adam's (Rama's) Bridge, and Mannar Island. The southwest part of the strait is also known as Palk Bay [25]. The strait is less than 100 m deep, 64 to 135 km wide, and 137 km long.…”

The rare earth elements (REEs) in the sediments of the South Vellar estuary on the eastern coast of India were measured using thermal ionization mass spectrometry (TIMS). Lanthanides (La-Lu) and a number of other elements (Cr, Ni, Zn, Pb, Ag, Co, Cd, and V) were studied in bed sediment samples. The estuary’s total REE content (REE) ranges from 73.30 to 360.50 g/g. Continental weathering has a substantial impact on the distribution of REEs. Using factor analysis on the elemental data, two important groups of elements were identified: (a) LREEs, HREEs, Pb, Ag, and Cd, revealing an association with river detritals; and (b) Co, Ni, Zn, Cr, and V, indicating complex estuary processes. Because of the silicate weathering of crustal materials and the resultant increase in LREEs in detritals, LREEs are more enriched than HREEs. We get to the conclusion that 30% of HREE flux and 70% of LREE flux to the Bay of Bengal are provided by the estuarine system.

“…In Ghana and elsewhere, farming occurs near these mines (Essumang et al 2007), and arsenic (As), cadmium (Cd), and other contaminants have been observed in these soils which can then be absorbed by crops (Essumang et al 2007; Bempah and Ewusi 2016). Both Cd and As are highly harmful contaminants in the environment that lead to heavy metal pollution of soil and water due to natural weathering of geological materials, industrialization, pesticides, fertilizers, mining, and manufacturing (Garelick et al 2009; Govindasamy et al 2011; Ozbek et al 2014; Amel et al 2016). Due to their ability to accumulate through the food chain, Cd and As can adversely affect humans (Essumang et al 2007; Reeves and Chaney 2008; Huang et al 2017; Shahid et al 2017) where chronic Cd and As exposure has been connected to cancer and several other diseases (Reeves and Chaney 2008; Järup and Akesson 2009; Jomova et al 2011; Kamunda et al 2016; Huang et al 2017; Shahid et al 2017; Ayangbenro and Babalola 2017).…”

We investigated the phytoremediation potential ofSenna occidentalisL., a pantropical plant that has been associated with tolerance to heavy metal-contaminated soils around mining sites. Seedlings ofS. occidentaliswere exposed to cadmium chloride (CdCl2) and sodium arsenate (Na3AsO4) at concentrations of 200, 300, and 400 mg L-1under greenhouse conditions. Heavy metal tolerance was assessed by comparing biomass and stress indicators such as chlorophyll, proline, and hydrogen peroxide content. Arsenic treatment had more toxic effects than cadmium onSennaphysiology. Regardless of concentration of arsenic applied, the biomass decreased by 50% as compared to control and cadmium-treated plants. Chlorophyll content decreased with exposure to both heavy metals. Higher concentration of Cd and As (400 mg L-1) resulted in 50% reduction in chlorophyll content. Proline and hydrogen peroxide levels were higher in arsenic-treated plants compared to controls and cadmium-treated plants, indicating an enhanced stress response when exposed to arsenic. When heavy metal content was measured, there was a significant accumulation of arsenic in the leaves, stems, and roots, indicating that arsenic in these tissues was responsible for the profound changes in biomass, proline, and hydrogen peroxide content. In contrast, although significant, there was less cadmium uptake bySennaand tolerance can be seen, which was reflected by normal biomass, proline, and hydrogen peroxide levels. High translocation of metals from soil into roots and low translocation from root to shoot tissues suggests the potential forS. occidentalisto be used for phytostabilization of arsenic- and cadmium-contaminated soils.
