Wünscher G, Kersting H, Heberer H, Westmeier I, Wenzel V, Flechsig M, Matthaeus E.
PMID: 2057758
Sci Total Environ. 1991 Jan 01;101(1):101-9. doi: 10.1016/0048-9697(91)90108-q.

This paper describes the use of an interactive simulation system (SONCHES) as a model and databank system. The basic model is a physiologically based toxicokinetic model (partition coefficient concept). This model takes circulation times into consideration and includes a...

Mercury (Hg) was discharged in the late 1960s into the Penobscot River by a chlor-alkali production facility, HoltraChem. Using total Hg concentration profiles from 56 stations (58 sediment cores) in the Penobscot River (PBR), Mendall Marsh (MM), Orland River...

It was thought that the Southern Ocean was relatively free of microplastic contamination; however, recent studies and citizen science projects in the Southern Ocean have reported microplastics in deep-sea sediments and surface waters. Here we reviewed available information on...

Fluoride and iodine enrichment in groundwater of North China Plain: Evidences from speciation analysis and geochemical modeling.

The Science of the total environment

Li J, Zhou H, Qian K, Xie X, Xue X, Yang Y, Wang Y.
PMID: 28441602
Sci Total Environ. 2017 Nov 15;598:239-248. doi: 10.1016/j.scitotenv.2017.04.158. Epub 2017 Apr 22.

To better understand the enrichment of fluoride and iodine in groundwater at North China Plain (NCP), speciation analysis and geochemical modeling were conducted to identify the key hydrochemical processes controlling their mobilization in groundwater system. Groundwater fluoride and iodine...

Acacia shrubs respond positively to high severity wildfire: Implications for conservation and fuel hazard management.

The Science of the total environment

Gordon CE, Price OF, Tasker EM, Denham AJ.
PMID: 27692936
Sci Total Environ. 2017 Jan 01;575:858-868. doi: 10.1016/j.scitotenv.2016.09.129. Epub 2016 Sep 28.

High severity wildfires pose threats to human assets, but are also perceived to impact vegetation communities because a small number of species may become dominant immediately after fire. However there are considerable gaps in our knowledge about species-specific responses...

Low concentrations of persistent organic pollutants (POPs) in air at Cape Verde.
