“…As presented in Figure S2 , comparison of the upper values in the literature with the USEPA guidelines shows that, in China, several values are above the recommended limit [ 34 , 41 , 46 , 47 , 48 , 49 , 50 , 51 ]. In addition, several other studies have reported above-standard values in Ghana [ 40 , 52 , 53 ], India [ 42 ] and Nigeria [ 43 ].…”

“…The pooled central median concentration of Cr in soil was 34.79 mg/kg (see Figure 2 ) (IQR: 18.97–69.36 mg/kg), with the upper bound median value being 49.3 mg/kg ( Table 2 and Figure S3 ). The highest concentrations were recorded in Ghana [ 53 ], followed by China [ 35 ], India [ 42 ], Nigeria [ 43 ] and Thailand [ 54 ], in that order. In fact, almost all the studies on Cr and soil have been conducted in China and Ghana (see Figure S3 ).…”

The recycling of electronic waste (e-waste) contaminates ecosystems with metals, though a compilation of data from across sites worldwide is lacking, without which evidence-based comparisons and conclusions cannot be realized. As such, here, a systematic review of the literature was conducted to identify peer-reviewed studies concerning e-waste sites (published between 2005 and 2017) that reported on the concentration of heavy metals (Cd, Hg, As, Pb and Cr) in soil, water and sediment. From 3063 papers identified, 59 studies from 11 countries meeting predefined criteria were included. Reported metal concentrations were summarized, and a narrative synthesis was performed. This review summarized 8286 measurements of the aforementioned metals in soils (5836), water (1347) and sediment (1103). More than 70% of the studies were conducted in Asia. In nearly all cases, the average metal concentrations in a particular medium from a given site were above guideline values; suggesting soils, water and sediment at, or near, e-waste recycling sites are contaminated. Across all media, concentrations of Pb were generally highest, followed by Cr, As, Cd and Hg. The synthesized information demonstrates that e-waste sites worldwide are contaminated with metals, that geographic data gaps exist, that the quality of most studies can be improved and that action is needed to help reduce such levels to protect human health and the environment.

Assessment of Organophosphate and Carbamate Insecticides and Heavy Metal Contamination in Canal-Grown Water Morning Glory (Ipomoea aquatica Forssk) in Nakhon Nayok Province, Thailand

Excessive application of insecticides in agriculture has become an increasing trend in Thailand, where agriculture is common in the area. This problem leads to negative impacts on human health and environment. Therefore, this study focused on monitoring organophosphate and carbamate insecticides, and heavy metals (Cd, Cu, Pb, Ni, Hg, Zn and Mn) in Ipomoea aquatica Forssk, as well as water and soil from different canals in Ongkharak District, Nakhon Nayok Province, Thailand. The powder samples were prepared from roots, stems and leaves of Ipomoea aquatica Forssk, as well as soil. Then, anti-acetylcholinesterase activity of each sample was determined, and heavy metal contents were measured by atomic absorption spectrometry. The results showed that the highest anti-acetylcholinesterase activity was found in the soil samples, followed by those of leaves and stems, roots, and water, respectively. Additionally, the order of heavy metal concentration of stem and leaves, root, water and soil samples were Mn>Cu>Hg>Ni>Zn>Cd>Pb, Mn>Zn>Ni >Cu>Cd>Hg>Pb, Ni>Cu>Hg>Mn>Cd>Zn>Pb, and Mn>Cu>Ni>Zn>Pb>Cd>Hg, respectively. The concentration of Cu and Hg in stems and leaves were above the standard levels of Ministry of Public Health (2003), while Cu and Cd in root samples were above the standard levels. Additionally, the concentrations of Cd, Ni and Zn in all water samples were above the standard levels of Ministry of Natural Resources and Environment (1994), and the concentrations of Cu, Hg and Mn in certain water samples were above the standard levels. The translocation factors (TFroot and TFwater) and bioaccumulation factor (BAF) above 1 were observed in order of Cu>Ni>Cd>Zn>Mn, Mn>Zn>Ni >Cd, and Mn>Zn>Ni>Cd, respectively. The findings provide useful information to agricultural and public health authorities for a dialogue in policy development (i.e. the importation and use of pesticides) to minimize health risk of vulnerable population including farmers and nearby communities in the province, and thus strengthening equity in health.

“…[7], the concentration of selected heavy metals (cadmium, copper, chromium, lead and zinc) in Moringa oleifera and health risk was reported. Similarly, Neeratanaphan et al [8], investigated the heavy metal accumulation in rice near electronic waste dump sites and the related health risks. The fact that no such study as the one reported in this paper has been carried out in South Eastern Nigeria, makes this study unique.…”

Elemental Characterization of Rice Husk Ash from Local Rice Species in South Eastern Nigeria

Heavy metals such as Cr, Zn, As, Pb and Cu can be hazardous to health and the environment. The focus of this study is to investigate the trace metal constituents of rice husk ash (RHA) from Ikwo and Izzi rice clusters. RHA of Izzi CP, R8 and Ikwo CP rice husk species were sampled. Elemental characterization was done using X-ray fluorescence method. A total of 14 elements (K, Ca, Ti, Cr, Mn, Fe, Cu, Zn, Rb, As, Br, Sr and Ga) were detected in the rice husk species except in Izzi CP where Ga was not detected. The concentration of these elements in weight percent (wt. %) were compared with literature. Elements like, K, Ca, Fe, and Mn were found to be in negligible concentrations in all the samples while Ga, Rb, Cu, Cr, Zn, As and Ni were found to be well above the literature values. The X-ray fluorescence analysis of the samples showed that some toxic heavy metals like Cr, As, Ni, and Cu were of high concentrations compared to literature which for health reasons are not advisable to have long term exposure.
