“…Actually, several studies have considered the As metabolization capacity in aquatic organisms after exposure to this metalloid (Cordeiro et al, ; Nunes et al, ; Ventura‐Lima et al, ). However, until now, few studies evaluated the influence of antioxidants in the metabolization process of arsenic.…”

The bioaccumulation of metals is a problem for shrimp farming due to toxicity. As the water used in the culture tanks comes from environment, the shrimps can be exposed directly accumulating these metals, suffering the toxic effect and being a source of exposure for humans. So, alternatives that can minimize/avoid both accumulation and promote metabolism of metals are welcome. In this study, the Litopenaeus vannamei received the antioxidant lipoic acid (LA) through diet for 4 weeks and posteriorly were exposed to cadmium (Cd) and arsenic (As) alone or in combination (nominal concentration of 1 mg/L) during 48 hr. A control group also was run in parallel (without LA and then submitted to both metals exposure). The accumulation of Cd and As and the capacity of As metabolization were analysed in gills, hepatopancreas and muscle of shrimp Litopenaeus vannamei. Our results showed that the LA administered through diet decrease the accumulation of both metals in gills and muscle and improved the metabolization of As, favouring the accumulation of non‐toxic compounds as arsenobetaine (AsB) in all organs analysed. Therefore, a diet enriched with LA is a good form of chemoprevention in aquaculture that improved the resistance of shrimps against metal contamination.

Wide nanotechnology applications and the commercialization of consumer products containing engineered nanomaterials (ENMs) have increased the release of nanoparticles (NPs) to the environment. Titanium dioxide, aluminum oxide, zinc oxide, and silica NPs are widely implicated NPs in industrial, medicinal, and food products. Different types of pollutants usually co-exist in the environment. Heavy metals (HMs) are widely distributed pollutants that could potentially co-occur with NPs in the environment. Similar to what occurs with NPs, HMs accumulation in the environment results from anthropogenic activities, in addition to some natural sources. These pollutants remain in the environment for long periods and have an impact on several organisms through different routes of exposure in soil, water, and air. The impact on complex systems results from the interactions between NPs and HMs and the organisms. This review describes the outcomes of simultaneous exposure to the most commonly found ENMs and HMs, particularly on soil and aquatic organisms.

In aquatic environment, engineered nanoparticles (ENPs) are present as complex mixtures with other pollutants, such as trace metals, which could result in synergism, additivity or antagonism of their combined effects. Despite the fact that the toxicity and environmental risk of the ENPs have received extensive attention in the recent years, the interactions of ENPs with other pollutants and the consequent effects on aquatic organisms represent an important challenge in (nano)ecotoxicology. The present review provides an overview of the state-of-the-art and critically discusses the existing knowledge on combined effects of mixtures of ENPs and metallic pollutants on aquatic organisms. The specific emphasis is on the adsorption of metallic pollutants on metal-containing ENPs, transformation and bioavailability of ENPs and metallic pollutants in mixtures. Antagonistic, additive and synergistic effects observed in aquatic organisms co-exposed to ENPs and metallic pollutants are discussed in the case of “particle-proof” and “particle-ingestive” organisms. This knowledge is important in developing efficient strategies for sound environmental impact assessment of mixture exposure in complex environments.
