On November 2015, one of Brazil's most important watersheds was impacted by the mine waste from Fundão dam collapse in Mariana. The traveled over 600 km along Doce River before reaching sea, causing severe devastation its way. Here we assessed trace element concentrations and cytogenotoxic effects released waste. Water samples were collected ten days after disaster two sites non-impacted site. Sampling points located hundreds kilometers downstream collapsed dam. used for quantification to...
Chlorinated paraffins (CPs) are widely produced chemicals, with certain CP subgroups facing global restrictions due to their environmental dispersion, persistence, bioaccumulation, and toxicity. To evaluate the effectiveness of these international restrictions, we assessed homologue group contribution mass fraction short-chain CPs (SCCPs: C10–C13), medium-chain (MCCPs: C14–C17), long-chain (LCCPs: ≥C18) in 36 technical mixtures used worldwide over last 50 years. Using low-resolution...
In southeastern Brazil, particular altitudinal grassland ecosystems, known as campos de altitude, occur at mountainous summits that host an outstand level of biodiversity and endemism. However, despite being environmentally protected areas, several studies have shown their susceptibility to the impacts climate changes airborne pollution. Previous highlighted semivolatile organic contaminants, such organochlorine pesticides (OCPs), present higher atmospheric concentrations along gradients can...
The expansion of the agribusiness sector, mostly fueled by international demand for agricultural commodities, is strongly associated with increasing pesticide applications. In Brazil, deforestation and land conflicts are also critical issues that have followed frontier expansion. this scenario, indigenous peoples their territories often found in a vulnerable position. Their reliance on natural resources, i.e., waterbodies potentially impacted pesticides, can lead to chronical exposure health...
Pharmaceutical usage has led to the widespread detection of these compounds in aquatic ecosystems worldwide, raising concerns about selective pressure they can exert on microbial communities. To aid tackling this global emergency, we undertook an initial step identifying potential hotspots bacterial resistance arising from occurrence antibiotics environment. This was conducted by performing a risk assessment based measured environmental concentrations selected antibiotics, acquired...
