Technological Methods

Environmental pollution due to heavy metals is a matter of great concern to many scientists and managers worldwide. The threats to human health from heavy metals are primarily associated with the exposure in agriculture production activities. However, a considerable number of technological methods have been used to remove the heavy metals from polluted soils. One of the simplest measures to effectively remove heavy metal contamination is to use both plants and microorganisms, which have been considered "natural materials" or "Bio-Materials" to treat pollutants. This study was conducted on assessing the ability of Trichoderma to absorb heavy metals into the plant. Phytoremediation experiments with Trichoderma were used to remove heavy metals in the soil. Our findings showed that Dracaena Fragrans plants are capable of absorbing heavy metals Cu, Pb, and Zn in soil contaminated with experimental heavy metals.

Background. Metal mining and waste discharge lead to regional heavy metal contamination and attract major concern because of the potential risk to local residents. Methods. This research was conducted to determine lead (Pb), cadmium (Cd), arsenic (As), manganese (Mn), and antimony (Sb) concentrations in soil and brown rice samples from three heavy metal mining areas in Hunan Province, central China, and to assess the potential health risks to local inhabitants. Results. Local soil contamination was observed, with mean concentrations of Cd, Pb, Sb, and As of 0.472, 193.133, 36.793, and 89.029 mg/kg, respectively. Mean concentrations of Cd, Pb, Sb, Mn, and As in brown rice were 0.103, 0.131, 5.175, 6.007, and 0.524 mg/kg, respectively. Daily intakes of Cd, As, Sb, Pb, and Mn through brown rice consumption were estimated to be 0.011, 0.0002, 0.004, 0.0001, and 0.0003 mg/(kg/day), respectively. The combined hazard index for the five heavy metals was 22.5917, and the total cancer risk was 0.1773. Cd contributed most significantly to cancer risk, accounting for approximately 99.77% of this risk. Conclusions. The results show that potential noncarcinogenic and carcinogenic health risks exist for local inhabitants and that regular monitoring of pollution to protect human health is urgently required.
