Special Issue Information

Dear colleagues,

Invertebrates represent the vast majority of all known animal species, inhabiting multiple habitats of the planet. Moreover, they perform key roles in various ecosystem functions. With the exception of the imposex phenomenon in gastropods, that is indisputably associated with organotin exposure and has received large attention in recent decades, most research in the field of endocrine-disrupting chemicals has focused on vertebrates. This is mostly related to the lack of knowledge of invertebrate endocrinology and available genomic resources. However, the full genome and transcriptome projects conducted for most invertebrate taxa over the past decade have brought about an unprecedent tool for addressing the hazard assessment of endocrine-disrupting chemicals in invertebrates. Several examples indisputably demonstrate that the genomic constitution of a given species is a key aspect that determines its response towards chemical insults. Therefore, disclosing the molecular constitution of different taxa is fundamental to understanding the mode of action (MoA) of environmental pollutants. Understanding the MoA of environmental chemicals allows the building of a toxicant response, thus becoming a central piece of hazard assessment.

For this Special Issue, we invite high-quality original research papers, short communications, and reviews focusing on all aspects of hazard assessment of endocrine-disrupting chemicals in invertebrates. Studies may be in vivo, in vitro, and in silico studies including both field and laboratory approaches. Research on single chemicals, mixtures, and complex environmental samples are welcome. We also welcome computational or predictive studies.

The integrated use of plant-derived volatile attractants and synthetic insecticides in attract-and-kill programs is a useful tool for integrated pest management programs reducing pesticide input. Efficient alternative insecticides are critically needed to replace methomyl, which has been banned on cruciferous vegetables in China because it is also highly toxic to nontarget organisms. In the present study, among 15 commonly used insecticides were screened for toxicity against S. litura moths, where chlorantraniliprole, flubendiamide, and emamectin benzoate was found to have the highest levels of toxicity (LC50 of 0.56, 3.85, and 6.03 mg a.i. L−1 respectively). After exposure to the low lethal concentration LC50 of chlorantraniliprole, fecundity of the moths was substantially reduced. Egg-hatching was lower for LC20- and LC50-treated moth pairs than for untreated control pairs. Net reproductive rate (R0), intrinsic rate of increase (r), and finite rate of increase (λ) were significantly reduced in LC50♀ × LC50♂ cohorts. Larval mortality was significantly higher in subsequent generations in pairs of LC50-treated moths. Chlorantraniliprole, which was most toxic and had significant sublethal effects on moths, can be used as an alternative insecticide to methomyl in the attracticide for controlling S. litura moths, and the LC50 indicated a high potential for efficacy in the control S. litura through attract-and-kill schemes.

The impact of metals bioaccumulation in marine organisms is a subject of intense investigation. This study was designed to determine the association between oxidative stress induced by seawater enriched with trace metals and protein synthesis using as a model the mussels Mytilus galloprovincialis. Mussels were exposed to 40 μg/L Cu, 30 μg/L Hg, or 100 μg/L Cd for 5 and 15 days, and the pollution effect was evaluated by measuring established oxidative biomarkers. The results showed damage on the protein synthesis machine integrity and specifically on translation factors and ribosomal proteins expression and modifications. The exposure of mussels to all metals caused oxidative damage that was milder in the cases of Cu and Hg and more pronounced for Cd. However, after prolonged exposure of mussels to Cd (15 days), the effects receded. These changes that perturb protein biosynthesis can serve as a great tool for elucidating the mechanisms of toxicity and could be integrated in biomonitoring programs. Full article
