“…The most assimilating toxic metal in rice is As, which is more efficient throughout seeds compared to other staple cereal crops [16]; inorganic As and dimethyl arsenic (DMA) dominate grain As speciation [17,18]. The key point sources of pollution in paddies and the resulting increase in As concentrations in grains have been characterized and documented in several studies and include the application of arsenical pesticides [19,20], irrigation with groundwater contaminated with As [21,22], and fertilization with municipal solid wastes [23]. The major problems arising in rice production in Asia are linked to rice breeding, the overuse of fertilizers and pesticides, the breakdown of irrigation infrastructure, oversimplified crop management, and a weak extension system [24].…”

Identifying heavy metal and pesticide contaminants is an essential step in assessing the health indicators of rice cultivation and consumption in Africa. Information on the contaminant levels of the imported and cultivated rice consumed in Senegal seems lacking. In this study, we assessed heavy metals, pesticides, ash, and protein in rice using rice samples from India, Thailand, South America, Vietnam, and China. Arsenic, Pb, Cd, Ni, Cu, Mo, Co, Cr, and Al are usually found in the soils used for rice cultivation in northern Senegal. While the heavy metal levels measured in soils were above the threshold limit, only Pb, Cd, and Al were found in cultivated rice. In all the analyzed rice samples from each country, there were certain amounts of Pb, As Al, and Cd. The concentration ranges in the six countries were as follows: 0.635–1.165 mg kg−1 for Pb, 0.047–0.438 mg kg−1 for As, 2.22–95.54 mg kg−1 for Al, and 0.002–0.082 mg kg−1 for Cd. The protein content in cultivated rice in Senegal was 7.31 mg kg−1, while the average from the imported rice ranged between 6.42% and 7.32%. The humidity levels in imported rice ranged between 11.12% and 12.95%. The fat content for the rice from six countries ranged between 0.22% and 0.67%, and the ash content ranged between 0.23% and 0.48%. These results allowed for the determination of the carbohydrate concentration, which varied between 79.18% and 80.82%. Indeed, freshly harvested rice grains typically contain around 80% carbohydrates. We noticed the presence of pesticides in all rice samples. The levels of three pesticides (total Pyrethrin, Bensulfuron-methyl, Propanyl, and 2,4D) were found to be beyond their maximum residue limits (MRLs) from the Codex Alimentarius, whereas deltamethrin was found to be below its MRL. This study indicates the presence of heavy metals carcinogenic to humans (Al, As, Cd, and Pb). Additionally, this study reveals the presence of deltamethrin, which is classified as probably carcinogenic to humans (Group 1), and 2,4-dichlorophenoxyacetic acid, which is classified as possibly carcinogenic to humans (Group 2B).

Agricultural application of Municipal Solid Waste (MSW), as nutrient source for plants and as soil conditioner, is the most cost-effective option of MSW management because of its advantages over traditional means such as landfilling or incineration. However, agricultural application of MSW can lead to a potential environmental threat due to the presence of pathogens and toxic pollutants. Composting is an attractive alternative of MSW recycling. Application of MSW compost (MSWC) in agricultural soils can directly alter soil physicochemical properties as well as promote plant growth. The soil microbial biomass, considered as the living part of soil organic matter, is very closely related to the soil organic matter content in many arable agricultural soils. Numerous studies, with different MSWC amendment doses on different soil types and under different water regimes revealed no detrimental effect on soil microbial biomass. In this review, we show the state of art about the effects of MSWC amendment on soil microbial biomass.
