Exploring global oceanic persistence and ecological effects of legacy persistent organic pollutants across five decades.

Global monitoring of persistent organic pollutants (POPs) has intensified following regulatory efforts aimed at reducing their release. In this context, we compiled over 10,000 POP measurements, reported from 1980 to 2023, to assess the effectiveness of these legislative measures in the global marine environments. While a general decreasing trend in legacy POP concentrations is evident across various maritime regions, highlighting the success of source control measures, the Arctic Ocean and its marginal seas have experienced a rise in POP levels.

Academic education in environmental chemistry in Europe-addressing future challenges in research and regulation.

Following the tradition of the 16th International Conference on Chemistry and the Environment (ICCE) in Oslo, Norway (2017), and the subsequent 17th ICCE in Thessaloniki, Greece (2019), a follow-up session on higher education in environmental science was organized at the 18th ICCE in Venice, Italy (June 2023). The aim of the session was to stimulate the exchange of experiences and knowledge on graduate and post-graduate level educational programmes, including their development, prioritization, and implementation. The session discussed the integration of practical training activities, which included the integration of environmental chemistry in various bachelor's and master's programmes.

High-throughput screening of 222 pesticides in road environments in a megacity of northern China: A new approach to urban population exposure.

A large number of pesticides have been widely manufactured and applied, and are released into the environment with negative impact on human health. Pesticides are largely used in densely populated urban environments, in green zones, along roads and on private properties. In order to characterize the potential exposure related health effects of pesticide and their occurrence in the urban environment, 222 pesticides were screened and quantified in 228 road dust and 156 green-belt soil samples in autumn and spring from Harbin, a megacity in China, using GC-MS/MS base quantitative trace analysis.
