What is Occurrence of legacy organochlorine pesticides in small mammals from two mountainous National Parks in southeastern Brazil about?
In southeastern Brazil, particular altitudinal grassland ecosystems, known as campos de altitude, occur at mountainous summits that host an outstanding level of biodiversity and endemism. However, despite being environmentally protected areas, several studies have shown their susceptibility to the impacts of climate change and airborne pollution. Previous studies highlighted that organochlorine pesticides (OCPs), present higher atmospheric concentrations along altitudinal gradients and can be locally deposited. On top of that, formerly used OCPs are still detected in the atmosphere on those mountaintops, long after their phase-out. Nevertheless, the potential bioaccumulation of OCPs by endemic species has not yet been assessed. Thus, we aimed to investigate the occurrence of OCPs in terrestrial subalpine wildlife and to establish a baseline for further in-depth studies on OCPs, or similar hazardous chemicals, in these endangered environments. In summary, 28 OCP congeners were investigated in 49 liver samples of ten small mammal species collected in 2013 and in 2016. Chemical analyses were based on gas chromatography coupled with electron capture negative ionization mass spectrometr
