TL;DR: It was found that most of the heavy metals existed in the oxizable and residual forms after pyrolysis, resulting in a significant reduction in their bioavailability, leading to a very low environmental risk of the biochar.

TL;DR: The co-pyrolysis technology provides a feasible method for the safe disposal of metal-contaminated sewage sludge in an attempt to minimize the environmental risk from potentially toxic metals after land application.

TL;DR: The results of principal component analysis and hierarchical clustering analysis indicate that marine aquaculture activities have enriched the surface sediments underneath mariculture rafts with Cu, Zn and Pb, possibly due to the accumulation of unconsumed fish feeds, fish excreta and antifouling paints.

TL;DR: Findings indicated that workers may be exposed to cancer risks above the acceptable range at 147 in a million at the 95th percentile in the dismantling area, and workers should be informed of associated risks to safeguard their health.

TL;DR: Mariculture activities increased total mercury, organic matter, carbon, nitrogen and sulfur concentrations in the surface sediments underneath mariculture sites, possibly due to the accumulation of unconsumed fish feed and fish excretion, but methylmercury (MeHg) concentrations and the ratio of MeHg to THg (% MeHG) in sediment underneath maricultural sites were lower than the corresponding reference sites.
