Local variability in snow concentrations of chlorinated persistent organic pollutants as a source of large uncertainty in interpreting spatial patterns at all scales

Journal of Environmental Quality, Volume 51, Issue 3, Page 411-424, May/June 2022., 2022
Abstract Single point sampling, a widespread practice in snow studies in remote areas, due to logistical constraints, can present an unquantified error to the final study results. The low concentrations of studied chemicals, such as chlorinated persistent organic pollutants, contribute to the uncertainty.

Rapid Screening of 352 Pesticide Residues in Chrysanthemum Flower by Gas Chromatography Coupled to Quadrupole‐Orbitrap Mass Spectrometry with Sin‐QuEChERS Nanocolumn Extraction

Journal of Analytical Methods in Chemistry, Volume 2022, Issue 1, 2022., 2022
To analyze pesticide residues, GC coupled with quadrupole‐Orbitrap MS (GC‐Orbitrap‐MS) has become a powerful tool because of its unique characteristics of accurate mass full‐spectrum acquisition, high resolution, fast acquisition rates, and overcoming matrix interference. This paper presents an efficiency evaluation of GC‐Orbitrap‐MS for identification

Quality Status Analysis and Intrinsic Connection Research of Growing place, Morphological Characteristics, and Quality of Chinese Medicine: Cyperi Rhizoma (Xiangfu) as a Case Study

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Aim of the Study. We set out to investigate the quality status of CR in China objectively according to the Chinese Pharmacopeia (ChP). We also explored the correlation between its growth area, morphological characteristics, and quality by analyzing physical and chemical indexes from 47 batches of CR collected from 12 provinces belonging to six ...

Nutritional Quality and Assessment of Contaminants in Farmed Atlantic Salmon (Salmo salar L.) of Different Origins

Journal of Food Quality, Volume 2022, Issue 1, 2022., 2022
Atlantic salmon represents an important source of valuable proteins and lipids rich in n‐3 fatty acids and micronutrients. However, there are reports that these marine fish still contain contaminants at levels that raise health concerns. Although the Stockholm Convention already bans some compounds, they can still be detected because of their ...

Complex organochlorine pesticide mixtures as determinant factor for breast cancer risk: a population-based case–control study in the Canary Islands (Spain)

Environmental Health, 2012
Background All the relevant risk factors contributing to breast cancer etiology are not fully known. Exposure to organochlorine pesticides has been linked to an increased incidence of the disease, although not all data have been consistent.
