“…The poisonous heavy metals in food are often derived from the enrichment of crops, and contamination during food production, processing, storage and transportation. They can enter the human body through the food chain and have a harmful affection on humankind [124]. It is a potential risk for people because of their long-term accumulation in the human body.…”

The high speed of contaminants growth needs the burgeoning of new analytical techniques to keep up with the continuous demand for monitoring and legislation on food safety and environmental pollution control. Metal-organic frameworks (MOFs) are a kind of advanced crystal porous materials with controllable apertures, which are self-assembled by organic ligands and inorganic metal nodes. They have the merits of large specific surface areas, high porosity and the diversity of structures and functions. Latterly, the utilization of metal-organic frameworks has attracted much attention in environmental protection and the food industry. MOFs have exhibited great value as sensing materials for many targets. Among many sensing methods, fluorometric sensing is one of the widely studied methods in the detection of harmful substances in food and environmental samples. Fluorometric detection based on MOFs and its functional materials is currently one of the most key research subjects in the food and environmental fields. It has gradually become a hot research direction to construct the highly sensitive rapid sensors to detect harmful substances in the food matrix based on metal-organic frameworks. In this paper, we introduced the synthesis and detection application characteristics (absorption, fluorescence, etc.) of metal-organic frameworks. We summarized their applications in the MOFs-based fluorometric detection of harmful substances in food and water over the past few years. The harmful substances mainly include heavy metals, organic pollutants and other small molecules, etc. On this basis, the future development and possible application of the MOFs have prospected in this review paper.

“…Toxic heavy metal can enter into the aquatic environment and accumulated in major and important organs of human beings, such as liver and kidney 7,8,9,10,11 . Heavy metals have bioavailability, enrichment, non‐degradability, and potential ecological risk in the sludge, which become one of the most restrictive factors of agricultural use 12,13,14,15 . Therefore, evaluating heavy metal ecological risk in the sludge, which is a great significance for sludge agricultural use.…”

“…Risk assessment is generally used for evaluation of the potential human health or ecological risks and estimation of the probability of heavy metal adverse effects 16 . Several risk assessment methods such as geo‐accumulation index ( I geo ), potential ecological risk index ( RI ), metal pollution index ( MPI ), and risk assessment code ( RAC ) have been widely used in land application of sewage sludge 13,16 . Previous works have indicated the ecological risk assessment of sludge land application, also demonstrated that heavy metal of sludge risk assessment is a part of risk analysis and associated with heavy metal speciation exposure 7,13,16 .…”

The level of heavy metals of the sludge in the landfills has attracted the environmental researchers due to their non-biodegradability, persistence, toxicity and biomagnification. Heavy metals contamination and ecological risk assessment in the sludge landfills were assessed. In this work, the enrichment factor (EF) and geoaccumulation index were used to analyze heavy metal pollution degree in the sludge landfills. Meanwhile, the potential ecological risk index was used to assess heavy metals potential ecological risk in the sludge landfills. Results indicated that heavy metal concentrations order was Cr > Cd > Ni > Zn > As>Cu = Pb > Hg. Cr, Cd and Ni coefficient variation were 57%, 53% and 38%, respectively, which indicated that Cr, Cd and Ni content have a large range variation. EF and geo-accumulation index analyze heavy metal pollution degree in the sludge landfills. Results demonstrated that Hg, Cd, Cu and Zn obtained a high pollution degree. However, Cr, Ni, As and Pb have a low pollution in the sludge landfills. Potential ecological risk index indicated that Hg obtained the highest pollution degree, which demonstrated that the potential ecological risk level is the highest value (E r i ≥ 3500, RI ≥ 4163). Whereas, other heavy metals have a low pollution degree in the sludge landfills. Therefore, Hg, Cd and Cu content of sludge should be strictly restricted in agricultural use. Meanwhile, it should be strictly restricted Hg, Cd and Cu content of wastewater discharge, and reduced heavy metal content of sludge.
