Special Issue Information

Dear Colleagues,

Organic contaminants, especially persistent and resistant chemicals, are ubiquitous in several environmental compartments and humans. Knowledge around the presence, fate and sources of organic contaminants, including legacy and emerging ones, in the aquatic environment, such as in water, sediments, biota and humans, are needed to assist in ecological and human health risk assessments to evaluate their impact. In addition, as the amount of chemicals being produced and used in a multitude of applications steadily increases, the concern with emerging organic contaminants (EOC), which are normally not included in routine monitoring analysis and could potentially have toxic effects in the environment, is warranted—especially regarding the ones known as endocrine disruptor chemicals, shown to adversely affect aquatic organisms and human health at very low concentrations. The presence of these EOC in trace amounts in environmental and biological matrices has also brought challenges to the analytical chemistry community, which, with recent advances in mass spectrometry, will be able to detect several compounds simultaneously with more precision and accuracy.

The Special issue will cover the following topics:

  • Occurrence, fate, sources and environmental health risks of emerging contaminants of concern in the aquatic environment (water, sediment, biota);
  • Assessment of legacy and emerging organic pollutants in human, biological and environmental samples;
  • Improvements in mass spectrometry-based analytical methods for the determination of organic contaminants in environmental and biological samples;
  • Ecological and human health risk assessments.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Environmental Research and Public Health is an international peer-reviewed open access monthly journal published by MDPI.

Organochloride (OC) and polychlorinated biphenyl (PCB) concentrations were determined in the muscle tissue of fifty sardine samples (Sardinella brasiliensis) sampled off the south-east Brazilian shelf. The aim herein was to investigate OCs and PCBs composition profile, bioaccumulation potential and human risks. The concentrations of 18 organochlorine pesticides (OCPs) were below the method limit of quantification in most samples (ca. 94%), with few detected, namely δ-HCH, γ-HCH, Endosulfan I and II, Endosulfan Sulphate, DDE, Dieldrin, Endrin, Endrin Aldeide, Endrin Cetone and Metoxyclor. The median concentration for the Σ41 PCBs was 2.32 ng g−1, ranging from values below the limit of quantification (<LOQ) to 37.2 ng g−1. Based on the analyzed samples, the concentrations reported herein do not represent a risk for human consumption according to both national and international guidelines, nor do OC and PCB bioaccumulation in sardines appear to be a concern at the moment. These findings, although preliminary, represent a baseline for future comparisons of the quality of an important source of protein available to the poorest Brazilian population strata. Full article

Per- and polyfluoroalkyl substances (PFAS) are ever-present pollutants in the environment. They are persistent and bio-accumulative with deleterious health effects on biota. This study assesses the levels of PFAS in environmental matrices along the Nairobi River, Kenya. An aggregate of 30 PFAS were determined in water, while 28 PFAS were detected in sediments and plants using solid phase extraction then liquid chromatography–mass spectrometric techniques. In water, higher levels of perfluoroundecanoic acids of up to 39.2 ng L−1 were observed. Sediment and plant samples obtained in the midstream and downstream contained higher levels of perfluorooctanoic acid of up to 39.62 and 29.33 ng g−1, respectively. Comparably, levels of long-chain PFAS were higher in water and sediments than in plants. Sediment/water log distribution of selected PFAS ranged between 2.5 (perfluoroundecanoic acid) and 4.9 (perfluorooctane sulfonate). The level of perfluorooctane sulfonate (1.83 ng L−1) in water is above the acceptable level in surface water posing high human health and ecological risks. The observed PFAS concentrations and distribution were attributed mainly to multi-industries located along the river, among other sources. The knowledge of PFAS occurrence and distribution in Nairobi River, Kenya, provides important information to local regulatory agencies for PFAS pollution control. Full article
