“…Soil ecological problems caused by heavy metals contamination under irrigated sugarcane monoculture and agricultural expansion have attracted a great deal of research attention in the tropical areas yet not under arid conditions. Previous researches have inspected that soil microbial diversity, soil enzymatic activity, crop yield could be affected by different soil management practices, and all these soil crop quality properties were improved under intercropping systems than sugarcane monoculture (Yang et al 2013;Wang et al 2014;Solanki et al, 2020). Soil microbiological and enzymatic characteristics have been used as soil health indicators, since they are sensitive to changes in agricultural management practices (Souza et al, 2012).…”

Soils must receive maximum protection to assure sustainable agriculture and quality food production. Heavy metals tend to accumulate in the soil rather than decompose and at a certain limit of their content, toxic consequences for living organisms occur. This research was conducted to survey the contamination status of Cd, Cr, Ni, and Pb and microbial activity in soils affected by long-term sugarcane monoculture in Upper Egypt. The rise of diacetate fluorescein hydrolysis (FDA) ranged from 86.25 to 201.25 mg kg -1 soil•h -1 in sugarcane monoculture fields, while the increase under crop rotation fields showed higher and significant values ranged from 207.25 to 266.67 mg kg -1 soil•h -1 . In this study, generally soil microbial biomass and enzymatic activity was usually and significantly higher under crop rotation than sugarcane monoculture. The highest potential ecological risks were found in soils under long-term irrigated sugarcane monoculture, while being moderate for crop rotation. Under both sugarcane monoculture and crop rotation farming systems, cadmium Cd was observed to be the urgency pollutant with the highest degree of contamination even though Cd had the lowest average concentration (Cd 27.03 mg kg -1 ) in sugarcane monoculture fields, and Cd (10.46 mg kg -1 ) in crop rotation. In view of the impacts of these potentially toxic elements of cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb), on the ecological system and public health, the introduction of new management practices in sugarcane monoculture fields are essential to protect the environment and to achieve future sustainability in sugarcane production in Upper Egypt.

“…The pooled central median concentration of Cd in soil was 1.11 mg/kg ( Figure 2 ) (IQR: 0.18–4.81 mg/kg), with the upper bound median value being 2.48 mg/kg ( Table 2 and Figure S2 ). The highest concentrations were recorded in China [ 41 ], followed by Ghana [ 40 ], India [ 42 ], Nigeria [ 43 ], Japan [ 44 ] and Vietnam [ 45 ] (see Figure S2 ). In fact, almost all studies on Cd and soil have been conducted in China.…”

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.

“…Africa generates relatively little e-waste but it receives thousands of tons of e-waste each year from developed countries [9]. The e-waste that is processed across Africa contains chemical substances that potentially pose risks to the environment including (air, soil and water,) [8] [10] as well as health risks to e-waste the workers [7] [8] [11] [12]. Several studies have shown that recyclers have little knowledge of the health and environmental risks associated with the e-waste recycling activities [7] [13] as they are primarily motivated by financial benefits [14].…”

Objective: The e-waste recycling is increasing worldwide, yet there remain outstanding environmental and occupational health concerns. Most research conducted on e-waste recycling has focused on only few countries (e.g., China, Ghana), thus there is a need to increase understanding of e-waste workers' (recyclers') knowledge and practices in other locations, that is purpose of this study. Methods: In a cross-sectional study conducted in Cotonou, Benin, 45 e-waste recyclers were interviewed from September to November 2018. Survey data was collected concerning their demographics, professional practices, and knowledge of occupational and environmental risks associated with e-waste recycling. Results: Most participants reported the following methods of material recovery of electronic items in declining orders: dismantling (97.8%) > sorting (91.1%) > incinerating (88.9%). Only 44.2% of the recyclers reported wearing ≥ 1 piece of personal protective equipment (PPE). More than 90% of e-waste workers noted that they disposed the e-waste in natural sites. About half, 46.7% believed that e-waste can pollute water and 71.1% considered that it can pollute air and soil. Recyclers reported several diseases including respiratory (67.4%), heart (62.8%), eye (65.1%), kidney (41.9%) and cancers (30.2%) could be linked to their work, respectively. Interestingly, we also found associations between the number of electronic items dismantled per month and self-report symptoms from the e-waste recyclers such as finding blood in urine and stool, wounds, dizziness, and itchy skin. Our results also indicated associations between the number of How to cite this paper: Houessionon,
