“…In European countries, atmospheric Cadmium is emitted around 85-90% by anthropogenic sources, mainly from fossil fuel combustion, and municipal waste incineration (Besser et al 2015). A very specific study reports the Cd concentrations measured in different environmental markers i.e.…”

“…Although the release of heavy metals into the environment is a natural process (Quantin et al 2001;Adamo et al 2003), anthropogenic sources also release high quantities into concentrated areas that are often near population centres or agricultural regions (Chabukdhara and Nema 2013;Besser et al 2015).…”

“…In particular, agroecosystems fertilised with repeated manures and synthetic fertilisers application can be polluted with metals (Chen et al 2013;Besser et al 2015) that do not decay, are characterised by latent toxicity and continuously present in the environment, entering into biological cycles (Epstein and Bassein 2001).…”

The aim of this research was to evaluate as a proof of concept, a quantitative relationship between atmospheric particulate matter (PM 10 ), atmospheric heavy metals (Pb, Ni and Cd) and Pb, Ni and Cd concentrations accumulated on bees reared in a beehive in the urban territory in Milan. For this purpose, a beehive called the Honey Factory, located in the Triennale museum area in Milano, was considered in the trial from May to October 2015. Every two days, bees found dead in the beehive were collected and the concentration of lead, cadmium and nickel on the bees bodies were evaluated through atomic absorption analysis. In the same period, data about atmospheric dust, Lead, Cadmium and Nickel, were daily downloaded by the ARPA website. The comparison between atmospheric and animal data has revealed a tight relation. Linear regressions for animals and atmosphere were calculated: when the concentration of atmospheric lead exceeded the value of 4 ng/m3, bees 'carried' about 0.7 mg/kg of lead. When the lead atmospheric concentration was higher than 15 ng/m3, lead on the bee's body was more than 0.9 mg/kg (y ¼ 0.1006x þ 0.573, R 2 ¼ 0.98). A similar relationship was detected for Nickel. This study showed that heavy metals accumulated on honeybees depend on the atmospheric concentrations measured during the month before animal sampling and that PM 10 pollution level seems to contribute to Pb and Ni levels detected on the animals. HIGHLIGHTSBees are environmental quality indicators. Pb, Ni, Cd (HM) were detected on bees and in the air. HM on bees depend on the atmospheric concentration. ARTICLE HISTORY

“…Given the relatively low toxicity of polyacrylamide to freshwater mussels observed during the present study, the benefits of polyacrylamide use for turbidity control may supersede the risk of toxic effects. Freshwater mussels can be greatly affected by suspended sediments and the contaminants associated with them . Also, polyacrylamide has the potential to decrease certain chemical toxicants and reduce nutrient loading .…”

Polyacrylamide has become an effective tool for reducing construction-related suspended sediment and turbidity, which are considered to have significant adverse impacts on aquatic ecosystems and are a leading cause of the degradation of North American streams and rivers. However, little is known about the effects of polyacrylamide on many freshwater organisms, and prior to the present study, no information existed on the toxicity of polyacrylamide compounds to native freshwater mussels (family Unionidae), one of the most imperiled faunal groups globally. Following standard test guidelines, we exposed juvenile mussels (test duration 96 h) and glochidia larvae (test duration 24 h) to 5 different anionic polyacrylamide compounds and 1 non-ionic compound. Species tested included the yellow lampmussel (Lampsilis cariosa), an Atlantic Slope species that is listed as endangered in North Carolina; the Appalachian elktoe (Alasmidonta raveneliana), a federally endangered Interior Basin species; and the washboard (Megalonaias nervosa), a common Interior Basin species. We found that median lethal concentrations (LC50s) of polyacrylamide ranged from 411.7 to >1000 mg/L for glochidia and from 126.8 to >1000 mg/L for juveniles. All LC50s were orders of magnitude greater (2-3) than concentrations typically recommended for turbidity control (1-5 mg/L), regardless of their molecular weight or charge density. The results demonstrate that the polyacrylamide compounds tested were not acutely toxic to the mussel species and life stages tested, indicating minimal risk of short-term exposure from polyacrylamide applications in the environment. However, other potential uses of polyacrylamide in the environment (e.g., wastewater treatment, paper processing, mining, algae removal) and their chronic or sublethal effects remain uncertain and warrant additional investigation.

“…Past ecotoxicological studies do not provide direct information on the contribution of dietary Cu to toxicity because only epibenthic (H. azteca) or pelagic (D. obtusa) organisms were tested (Burton et al, 2001;Rossi and Beltrami, 1998). Although laboratory tests may not be able to fully catch long-term toxic effects on long-lived organism in field conditions, Besser et al (2015) report a significant relationship between percentage amphipod survival in standard tests and invertebrate taxa richness in the Vermont copper belt. However, findings from laboratory tests may not directly apply to real field situations (Ferrari et al, 2014).…”
