Climate warming shifts riverine macroinvertebrate communities to be more sensitive to chemical pollutants
<p>Freshwaters are highly threatened ecosystems that are vulnerable to chemical pollution and climate change. Freshwater taxa vary in their sensitivity to chemicals and changes in species composition can potentially affect the sensitivity of assemblages to chemical exposure. Here we explore the potential consequences of future climate change on the composition and sensitivity of freshwater macroinvertebrate assemblages to chemical stressors using the UK as a case study.</p> <p>Macroinvertebrate assemblages under end of century (2080-2100) and baseline (1980-2000) climate conditions were predicted for 608 UK sites for four climate scenarios corresponding to mean temperature changes of 1.28°C to 3.78°C. Freshwater macroinvertebrate toxicity data were collated for 19 chemicals and the hierarchical Species Sensitivity Distribution (hSSD) model was used to predict the sensitivity of untested taxa using relatedness within a Bayesian approach. All four future climate scenarios resulted in shifts in assemblage composition, with increases in the prevalence of molluscan, crustacean and annelid species, and towards increasing insect taxa of Odonata, Chironomidae, and Baetidae species. In contrast decreases in were projected for Plecoptera, Ephemeroptera (except for Baetidae) and Coleoptera species.</p> <p>Shifts in taxonomic composition were associated with changes in the percentage of species at risk from chemical exposure. For the 3.78°C climate scenario, 76% of all assemblages became more sensitive to chemicals and for 18 of the 19 chemicals, the percentage of species at risk increased. Climate warming-induced increases in sensitivity were greatest for assemblages exposed to metals and were dependent on baseline assemblage composition, which varied spatially.</p> <p>Climate warming is predicted to result in changes in the use, environmental exposure and toxicity of chemicals. Here we show that, even in the absence of these climate-chemical interactions, shifts in species composition due to climate warming will increase chemical risk and that the impact of chemical pollution on freshwater macroinvertebrate biodiversity may double or quadruple by the end of the 21st century.</p>

Data for: Associations between faecal chemical pollutants and hormones in primates inhabiting Kibale National Park, Uganda
<p>While anthropogenic pollutants are known to be a threat to primates, our understanding of exposure to pollutants <em>in situ</em>and their sub-lethal effects is still limited. We used noninvasive biomonitoring to examine associations between fecal concentrations of 97 chemical pollutants and fecal hormone metabolites of cortisol and estradiol in four primate species inhabiting Kibale National Park, Uganda (chimpanzees - <em>Pan troglodytes</em>, olive baboons - <em>Papio anubis</em>, red colobus - <em>Piliocolobus tephrosceles</em>, and red-tailed monkeys - <em>Cercopithecus ascanius</em>). Across all species (n = 71 samples), our results demonstrated positive associations of organochlorine pesticides (<em>ß</em> = 0.143, p = 0.020) and organophosphate esters (<em>ß</em> = 0.112, p = 0.003) with cortisol in adult females. Additionally, we observed positive associations of organochlorine pesticides (<em>ß</em> = 0.192, p = 0.013) and brominated flame retardants (<em>ß</em> = 0.176, p = 0.004) with cortisol in juveniles. Our results suggest that cumulative pesticides and flame retardants are disruptive to endocrine function in these populations, which could have implications for development, metabolism, and reproduction. Our results further demonstrate that feces can be an important, noninvasive matrix for examining pollutant-hormone associations in wild primates and other critical wildlife populations.</p>

Dataset associated with the paper "Thyroid Cancer and Endocrine Disruptive Chemicals: A Case-Control Study on Per-fluoroalkyl Substances (PFAS) and Other Persistent Organic Pollutants (POPs)"
<h2>Abstract</h2> <div> <p><strong>Objective: </strong>To evaluate the possible association between some endocrine disruptive chemicals and thyroid cancer (TC) in an Italian case-control cohort.</p> <p><strong>Methods: </strong>We enrolled 112 TC patients and 112 sex- and age-matched controls without known thyroid diseases. Per- and poly-fluoroalkyl substances (PFAS), poly-chlorinated biphenyls (PCBs), and dichlorodiphenyltrichloroethane (4,4'-DDT, and 4,4'-DDE) were measured in the serum by liquid or gas chromatography-mass spectrometry. Unconditional logistic regression, Bayesan Kernel Machine Regression and Weighted Quantile Sum models were used to estimate the association between TC and pollutants' levels, considered individually or as mixture. BRAFV600E mutation was assessed by standard methods.</p> <p><strong>Results: </strong>The detection of perfluorodecanoic acid (PFDA) was positively correlated to TC (OR= 2.03, 95% CI 1.10-3.75, p=0.02), while a negative association was found with perfluorohexanesulfonic acid (PFHxS) levels (OR=0.63, 95% CI 0.41-0.98, p=0.04). Moreover, perfluorononanoic acid (PFNA) was positively associated with the presence of thyroiditis, while PFHxS and perfluorooctane sulfonic acid (PFOS) with higher levels of pre-surgical Thyroid-Stimulating Hormone (TSH). PFHxS, PFOS, PFNA and PFDA were correlated with less aggressive TC, while poly-chlorinated biphenyls (PCB-105 and PCB-118) with larger and more aggressive tumours. Statistical models showed a negative association between pollutants' mixture and TC. BRAFV600E mutations resulted associated with PCB-153, PCB-138 and PCB-180.</p> <p><strong>Conclusions: </strong>Our study suggests, for the first time in a case-control population, that exposure to some PFAS and PCBs associates with TC and some clinical and molecular features. On the contrary, an inverse correlation was found with both PFHxS and pollutants' mixture, likely due to a potential reverse causality.</p> <p> </p> <p>Dataset associated with the paper "Thyroid Cancer and Endocrine Disruptive Chemicals: A Case-Control Study on Per-fluoroalkyl Substances (PFAS) and Other Persistent Organic Pollutants (POPs)".</p> <p>This set of raw data cannot be publicly available as including sensitive information, but might be made available to interested researchers upon reasonable request.
