Due to biosoilds contains plant nutrients and organic matter, its agriculture utilization is an important disposal or recycling method of this solid waste.In the past decade, there was much research on the forms, behaviors and bioavailability of heavy metals in biosolids and how they are transferred in soil/plant systems.Mean, the environmental effects of organic pollutants and pathogen in biosoilds were attracted more and more attentions.This review compared the properties of domestic and foreign biosolids.It also summarized current advances in agro-application of biosolids, with special emphasis on environmental risk and control criteria/standards.A significant scientific progress was made in this regard.Despite this effort, many uncertainties and data gaps remained in the science of regulation of boisolids in especially China.The review concluded that future studies should focus on the risks of agro-application of biosolids by setting up systematic, long-term field experiments.This would foster greater understanding of the environmental behaviors/effects of biosolid contamination.Such would facilitate the setting up of scientific criteria on the use ofbiosolids in agricultural lands.This brief but comprehensive review has thus provided vital information on future development and utilization of biosolids in agricultural lands.
