“…Recently, the effect of these toxic substances on human health is an intense concern due to ubiquity of exposure. According to the increased use of a wide variety of metals in manufacturing and our daily life through modern applications, problems resulting from the environmental toxic metal emissions have assumed serious dimensions [217].…”

Environmental problems have always received immense attention from scientists. Toxicants pollution is a critical environmental concern that has posed serious threats to human health and agricultural production. Heavy metals and pesticides are top of the list of environmental toxicants endangering nature. This review focuses on the toxic effect of heavy metals (cadmium (Cd), lead (Pb), copper (Cu), and zinc (Zn)) and pesticides (insecticides, herbicides, and fungicides) adversely influencing the agricultural ecosystem (plant and soil) and human health. Furthermore, heavy metals accumulation and pesticide residues in soils and plants have been discussed in detail. In addition, the characteristics of contaminated soil and plant physiological parameters have been reviewed. Moreover, human diseases caused by exposure to heavy metals and pesticides were also reported. The bioaccumulation, mechanism of action, and transmission pathways of both heavy metals and pesticides are emphasized. In addition, the bioavailability in soil and plant uptake of these contaminants has also been considered. Meanwhile, the synergistic and antagonistic interactions between heavy metals and pesticides and their combined toxic effects have been discussed. Previous relevant studies are included to cover all aspects of this review. The information in this review provides deep insights into the understanding of environmental toxicants and their hazardous effects.

“…Compared to other elements, the CVs of chromium, manganese, nickel, and vanadium were low, indicating a natural source affecting their spatial distribution. Past research has shown that the content of Cr and Ni in basic rock and ultrabasic rock is well above that of other parent materials [72,73], and chromium and nickel in the soil are mainly influenced by the parent material of soil formation [24,74,75]. For this reason, PC2 is primarily attributable to a natural source.…”

“…Some heavy metal(loid)s, e.g., As, Cd, Hg, and Pb, will lead to hazardous health problems such as renal insufficiency, liver injury, skin cancer, and painful osteoporosis [15][16][17], while other heavy metal(loid)s, such as Cu, Mn, Zn, etc., are necessary for the healthy growth of plants or animals but beyond a certain amount will also produce toxicity to organisms [18,19]. In recent decades, the accumulation of soil heavy metal(loid)s and the assessment on their ecological-health risk has become a widespread problem and drawn significant research attention worldwide [20][21][22][23][24]. A lot of research has been carried out on spatial distribution [25,26], migration process [27,28], source analysis [23,29,30], ecological risk assessment [20,22,31], and remediation [32,33] of heavy metal(loid)s in the soil.…”

To understand the environmental quality and heavy metal(loid) pollution of farmlands in Shangdan Valley, the contents of macroelements (Na, K, Si, Mg, Ca, Al, Fe, Ti, P, S, Cl, Br) and heavy metal(loid)s (Cu, Pb, Zn, Mn, Ni, V, Co, Cr, As) were surveyed by the X-ray fluorescence method. The pollution degree and ecological risk of the heavy metal(loid)s were judged by the Nemerow synthetic pollution index, geo-accumulation index, and potential ecological risk index, and their sources were identified by the multivariate statistic method. The mean contents of nine heavy metal(loid)s in Shangdan Valley farmland soil exceeded their corresponding reference values. Soils were not contaminated with As, Cr, Mn, and Ni but were slightly contaminated with Co, Cu, Pb, V, and Zn. Their comprehensive pollution levels were moderate to serious. The ecological risk index of single heavy metal(loid) decreased in the sequence As > Pb > Co > Cu > Ni > V > Zn > Cr > Mn. The source analysis results indicated that Cu, Pb, Zn, and As were highly affected by anthropogenic inputs, e.g., metal smelting and agricultural activities, while Mn, Ni, Cr, and V were principally derived from a natural source. As for Co, it was affected by a mixture source of nature, fossil fuel combustion, and fertilizer.

“…Soil contaminated with toxic metals is a serious environmental issue worldwide [ 1 , 2 ]. Toxic metals exhibit the potential of affecting the soil–food chain, impairing soil fertility [ 3 , 4 , 5 ] and the quality of drinking water [ 6 ]. Once they enter the food chain, toxic metals can trigger cell mutation, possibly causing cancer [ 5 , 7 , 8 ].…”

Once they enter the food chain, toxic metals can trigger cell mutation, possibly causing cancer [ 5 , 7 , 8 ]. Amongst these metals, Pb, Cd, Cu, Zn and Ni have elicited considerable concern because they are leached from tailings and discharged directly into adjacent streams and agricultural lands [ 9 ].…”

Low-cost absorbent materials have elicited the attention of researchers as binders for the stabilisation/solidification technique. As, there is a no comprehensive study, the authors of this paper investigated the performance of Oyster shell powder (OS), zeolite (Z), and red mud (RM) in stabilising heavy metals in three types of heavy metal-contaminated soils by using toxicity characteristic leaching procedure (TCLP). Samples were collected from surroundings of an abandoned metal mine site and from military service zone. Furthermore, a Pb-contaminated soil was artificially prepared to evaluate each binder (100× regulatory level for Pb). OS bound approximately 82% of Pb and 78% of Cu in real cases scenario. While Z was highly effective in stabilizing Pb in highly polluted artificial soil (>50% of Pb) at lower dosages than OS and RM, it was not effective in stabilising those metals in the soils obtained from the contaminated sites. RM did not perform consistently stabilising toxic metals in soils from contaminated sites, but it demonstrated a remarkable Pb-immobilisation under dosages over than 5% in the artificial soil. Further, authors observed that OS removal efficiency reached up to 94% after 10 days. The results suggest that OS is the best low-cost adsorbent material to stabilize soils contaminated with toxic metals considered in the study.
