“…The use of compost as fertilizer, soil conditioner, or substrate is a sustainable recycling practice due to its beneficial effects on the biological, physical, and chemical properties of the soil, as well as on plant growth (Mylavarapu and Zinati 2009). However, composting of municipal solid wastes may result in environmental risks depending on the trace-element concentration in the raw materials that are used, which makes the final use of the compost unsuitable for food production (Hargreaves et al 2008;Sharif et al 2016). Therefore, the ongoing monitoring of trace elements in composts is essential to guarantee an agroecological agriculture that protects human health and the environment (Nogales et al 2014).…”

Over the last three decades, urban agriculture has been improving food security in Cuba by providing fresh vegetables within and on the outskirts of cities and villages. However, organic fertilizers and substrates that are used in urban agriculture systems can be contaminated by trace elements and accordingly pose risks to human health. This study was carried out to measure the concentrations of cadmium, lead, arsenic, selenium, mercury, nickel, and chromium in composts and substrates used in Cuba's urban agriculture, as well as in vegetables grown in this cropping system to assess risks to human health. Extraction of trace elements from samples was performed with a mixture of nitric and hydrochloric acid in a microwave oven. Cadmium, lead, nickel, and chromium were determined via optical emission spectrometry, and mercury, selenium, and arsenic were measured using an atomic absorption spectrophotometer coupled with a hydride generation system. We demonstrated that the concentrations of trace elements in organic fertilizers, with the exception of compost from municipal solid waste, were within permissible values and do not pose risks to human health. The compost produced from municipal solid waste and the substrates prepared with this material presented cadmium and lead concentrations above maximum permissible concentrations. This work represents the first national-wide survey of trace elements in Cuban urban agriculture. As a result of this investigation, the use of municipal-solidwaste compost for food production was forbidden in Cuba.

“…Another study reported a high concentration of heavy metals in solid municipal waste composting due to uncontrolled leaching, along with runoff and compost, which subsequently degraded water quality and elevated environmental risk [41]. Eneji et al [6] reported that the major concern of soil pollution with available heavy metals by the use of manures can be minimized through composting under aerobic conditions.…”

“…Pollution load index (PLI) data in this study were interpreted according to the scheme reported by Tomlinson et al [36] and applied by Sharifi et al [33] and Vu et al [45] as follows: PLI = O: not polluted; PLI < 1: unpolluted; PLI ≥ 1: polluted. The higher the PLI, the higher the pollution.…”

Ecological and human health exposure risks to heavy metals in Oji River sediments: effect of abattoir and power station

et al. 2019

In this study, the ecological and human health exposure risks due to the effects of abattoir and power station on heavy metal input into the sediments of Oji River in Enugu State Nigeria were assessed. Heavy metals in the sediments were measured using atomic absorption spectrometry. Pollution of the sediments was assessed using: contamination factor (CF), degree of contamination (CD), geochemical accumulation index (I geo ) and pollution load index (PLI), whereas the ecological risk was assessed using potential ecological risk index. Non-carcinogenic risks of exposure by humans to the heavy metals were assessed using hazard index. Obtained results indicate that the abattoir contributed to heavy metal input into the sediments significantly (unlike the power station) and most likely due to the use of waste tires at the abattoir as fuel. All pollution parameters (CF, CD, I geo and PLI) reveal that pollution of the sediment with heavy metals around the abattoir is most profound and the ecological risk of heavy metals in the sediments is very high. Non-carcinogenic risk of exposure to heavy metals due to inadvertent ingestion and contact with sediments is insignificant.
