Opis:
Background Chemotherapy drugs are widely used to treat cancer, but their active compounds represent a danger for workers who could be exposed to them. However, they aren’t yet included in directive CE No. 1272/2008 and the European Biosafety Network has only recommended a limit value of 100 pg/cm2 for surface contamination. Thus, it is crucial to assess surface contaminations in healthcare environments. Currently, the technique of choice is surface wipe test combined with liquid chromatography tandem mass spectrometry to achieve high sensibility. Material and Methods A campaign involving Careggi University Hospital (Florence, Italy) was performed from January 2020 to December 2021, collecting 1449 wipe samples between administration units, preparation unit, and personnel gloves. From the obtained data, the 90th percentile was calculated for 30 antiblastic drugs and proposed as surface exposure levels (SELs); while from data concerning personnel glove contamination, weekly contamination was estimated. Results In the 2-year period only 417 wipe samples were found positive (28.8%), the majority of which regard samples coming from administration unit bathrooms. The proposed SELs are almost all <100 pg/cm2, except for few drugs which produce higher contamination on bathroom surfaces. Also, the estimation of pharmacy personnel’s glove contamination highlighted very low results (ng/week). Conclusions Deeply established protocols and procedures for safe handling of ADs allow for obtaining excellent cleaning results and thus a safer work environment, however, the risk of cytostatic contaminations cannot be avoided in healthcare workplaces, and thus a harmonization of classification and labeling of chemotherapy drugs throughout the European Union should be done.

Opis:
This study aimed to assess the element content of Porcini mushrooms collected from broadleaf Mediterranean forests (NW Italy) and underlying soil layers, and to elucidate the chemical connection between the mushrooms and their geographic site of origin. Comparing the elements in mushrooms with those in soil samples, we observed that the concentration of some microelements detected in mushrooms had similar distribution as that measured in both the soil layers assessed, especially with surface soil. Statistical analyses showed that the microelement pattern in mushrooms reflects the soil site of origin. Moreover, by comparing our results with other studies, we observed that the soil where Porcini grow is characterized by a high concentration of zinc. Some toxic elements were also detected in mushroom samples. Analysis of elements in mushrooms and soil layers can be used for quality assurance of natural products and help distinguish them from uncertified and unknown-origin products.
