Untargeted screening analysis for mycosporines and mycosporine-like amino-acids in algae by mass spectrometry
(Corresponding) Parailloux M., Godin S., C.M. Fernandes S., Lobinski R.
Topic:
Environmental biotechnology and bioenergy
Mycosporines and mycosporine-like amino acids have been described as natural sunscreens and antioxidant compounds presenting a great potential for health and cosmetic applications. Herein, an untargeted screening approach for mycosporines and mycosporine-like amino acids (MAAs) was developed by the...Read more

How to estimate biocide mass loads in urban water discharges and their impact on the river contamination?
(Corresponding) BRESSY A., PAIJENS C., TEDOLDI D., FRERE B., MAILLER R., ROCHER V., MOILLERON R.
Topic:
Emerging pollutants
Biocidal substances are ubiquitous in urban areas; they are used as preservatives in daily products, building materials, and as domestic pesticides. Despite these facts, urban sources of biocides, contrary to agricultural inputs, have been overlooked in terms of environmental risk assessment. The...Read more

High FAME yield Biodiesel from microalgae through nanocatalytic transesterification process.
Mittal V., (Corresponding) Ghosh U.
Topic:
Environmental biotechnology and bioenergy
Biodiesel production from microalgae is significantly important when reserves of petro-diesel are depleting, and utilization of vegetable oil-based fuel leads to food scarcity. The rapid growth and high lipid content of microalgae is an ideal feedstock for biodiesel production. The use of...Read more

Investigating the impact of landfill leachates in groundwater quality through the monitoring of multiclass emerging contaminants by LC-HRMS
(Corresponding) Nika M., Gkotsis G., Vasilatos K., Gkogkou A., Stasinakis A., Thomaidis N.
Topic:
Emerging pollutants
Due to their economic advantages, landfills are the primary repository of municipal solid wastes, receiving everyday by-products such as food wastes, plastic containers and product packaging materials, unused pharmaceuticals, textile and other products. As a result of the higher demand and better...Read more

Investigation of the presence of organic micropollutants in biota specimens from the Antarctica ecosystem using state-of-the-art wide-scope target and suspect HRMS methodologies.
Gkotsis G., Nika M., Vasilatos K., Orfanioti A., Athanasopoulou A., Alygizakis N., Oswald P., Slobodnik J., (Corresponding) Thomaidis N.
Topic:
Emerging pollutants
The contamination of the aquatic ecosystem with organic micropollutants due to anthropogenic activities, over the last decades, is a well-known issue. Due to the frequent detection of these chemicals in various environmental compartments, they are considered as potential threats to the aquatic...Read more

Selenate uptake by Chlamydomonas reinhardtii Algal Cells, its Transformation and its Effect on Membrane Lipid Profiles
Zkeri E., Mavrakis E., Panagou G., Grafanaki S., (Corresponding) Pergantis S., Lydakis-Simantiris N.
Topic:
Heavy metals in the environment
While selenium (Se) has been demonstrated to be essential for the optimal growth of freshwater microalgae Chlamydomonas reinhardtii [1], exposure to elevated concentrations of selenite (Se[IV]) or selenate (Se[VI]), the two major aqueous forms of Se, induce cell toxicity[2]. In this study,...Read more

Topic:
Emerging pollutants
After the first COVID-19 case in 2019 in Wuhan, China, the virus SARS-COV-2 has rapidly spread nationwide, alarming both the public and scientific community (Cascella et al., 2021). Currently, there are no treatments available for COVID-19, hence reducing the virus transmission and vaccinations...Read more
