TL;DR: The results indicated that approximately 60 years of Pb/Zn smelting has led to significant contamination of the local soil by Zn, Pb, Cd, As, Sb, and Hg, which exhibited maximum concentrations of 8078, 2485, 75.3, and 2.58mgkg(-1), dry wet, respectively.

TL;DR: The location of point pollution sources and prevailing wind direction were found to be important factors in the spatial distribution of heavy metals and there was significant enrichment of Pb, Zn, Co, Cu and Cr based on geo-accumulation index value.

TL;DR: Based on an analysis of the main environmental problems in mining areas, the utilization of a landscape strategy and natural technology in ecological restoration of mine is suggested in this article, where the principles and technologies of restoration ecology and landscape ecology can be used in the process of mine restoration to improve restoration and assure long-term results.

TL;DR: Investigation of the seasonal occurrence and spatial variation of 15 antibiotics in the Haihe River Catchment during 2016-2017 indicated that the use of veterinary antibiotics is probably increasing around the catchment, and indicates that further monitoring is needed on the more harmful and veterinary antibiotics in this catchment.

TL;DR: A risk assessment revealed that amoxicillin and enrofloxacin could pose high risks (risk quotient of > 1) to algae in the bay, and the synergic effects of pharmaceutical mixtures and the bioaccumulation of antibiotics through the food web should be considered in future studies.
