In this study, a combined system consisting of Cannabis sativa L. (hemp) and the blue-green alga Arthrospira platensis (spirulina) was tested to clean up soils contaminated with cadmium, chromium, copper, nickel, lead, and zinc.
The application of non-targeted NMR methods combined with ICP-AES quantification provided an efficient strategy for detecting residual heavy metals within plant tissues and soil. Importantly, non-targeted metabolomic analysis helped to reveal the relationships between metabolites distribution in hemp tissues and the sequestered metals.

Airborne microplastics and fibers in indoor residential environments in Aveiro, Portugal
The use of micro-spectroscopy methods is required to study smaller inhalable particles, benefiting from the use of silver membrane filters. Although these filters perform poorly during sample preparation, they can be stained with Nile Red and be used for pre-selection of suspected particles. Future inquiries require method development to better assess smaller size fractions relevant for human exposure.

Maternal dietary patterns during pregnancy and exposure to persistent endocrine disrupting chemicals in two European birth cohorts
Dietary patterns explained between 8 and 20% of the variation in serum EDC concentrations, with explained variance being the highest for PCBs in both cohorts. In conclusion, dietary patterns high in animal-based products appear to be associated with persistent EDC concentrations among pregnant women. Diet explains more variation in PCB concentrations than for other persistent EDC classes.

Measurement of natural radioactivity and radium equivalent activity for pottery making clay samples in Paraíba and Rio Grande do Norte – Brazil
High levels of environmental radioactivity are caused by the composition of minerals in the earth’s crust and the impact of prospection and utilization of natural sources, mainly due to the presence of 40K and radionuclides of 238U and 232Th series. Radium equivalent activity (RaEq) was calculated to assess the risk associated with primordial radionuclides.

Seasonal variation in tissue-borne heavy Metal(loid)s in herbaceous plants growing in contaminated soils developed from industrial wastes of industrial revolution age
The results show that different heavy metal(loid)s in the shoot tissue had different seasonal variation patterns. Seasonal shoot cutting-regrowth did not markedly affect the accumulation of various heavy metal(loid)s in the shoots. The concentration of shoot-borne heavy metal(loid)s was below the maximum tolerable level set for cattle except for Cd during spring-summer.
