“…From the point of view of potential applications in biofouling prevention, geotextiles could represent a new tool as an 'antifouling system' alternative to the dangerous biocide mixtures employed worldwide in antifouling paints. The latter have the potential to disrupt aquatic communities by releasing pollutants with deleterious effects on nontarget organisms (Ranke and Jastorff, 2000;Cima and Ballarin, 2008;Manzo et al, 2014). Therefore, in the last decades the research of new eco-friendly systems to prevent fouling settlement on artificial structures has become a primary requirement for the safeguarding of the coastal ecosystems.…”

“…One of the antifouling components, tributyltin, is so persistent, that even though its use was banned in 2008, it continues to be found in the environment. Alternative biocides for antifouling paints, such as irgarol (2-methylthiol-4-tert-butylamino-6-cyclopropylamino-s-triazine) and diuron also have widespread distribution in oceans, and may cause harmful effects despite their low concentrations (Manzo et al, 2014).

There is high demand for herbicides based on the necessity to increase crop production to satisfy world-wide demands. Nevertheless, there are negative impacts of herbicide use, manifesting as selection for resistant weeds, production of toxic metabolites from partial degradation of herbicides, changes in soil microbial communities and biogeochemical cycles, alterations in plant nutrition and soil fertility, and persistent environmental contamination. Some herbicides damage non-target microorganisms via directed interference with host metabolism and via oxidative stress mechanisms. For these reasons, it is necessary to identify sustainable, efficient methods to mitigate these environmental liabilities. Before the degradation process can be initiated by microbial enzymes and metabolic pathways, microorganisms need to tolerate the oxidative stresses caused by the herbicides themselves. This can be achieved via a complex system of enzymatic and non-enzymatic antioxidative stress systems. Many of these response systems are not herbicide specific, but rather triggered by a variety of substances. Collectively, these nonspecific response systems enhance the survival and fitness potential of microorganisms. Biodegradation studies and remediation approaches have relied on individually selected strains to effectively remediate herbicides in the environment. Nevertheless, it has been shown that microbial communication systems that modulate social relationships and metabolic pathways inside biofilm structures among microorganisms are complex; therefore, use of isolated strains for xenobiotic degradation needs to be enhanced using a community-based approach with biodegradation pathway integration. Bioremediation efforts can use omics-based technologies to gain a deeper understanding of the molecular complexes of bacterial communities to achieve to more efficient elimination of xenobiotics. With this knowledge, the possibility of altering microbial communities is increased to improve the potential for bioremediation without causing other environmental impacts not anticipated by simpler approaches. The understanding of microbial community dynamics in free-living microbiota and those present in complex communities and in biofilms is paramount to achieving these objectives. It is also essential that non-developed countries, which are major food producers and consumers of pesticides, have access to these techniques to achieve sustainable production, without causing impacts through unknown side effects.

“…Unfortunately, most of the biocides, like Cu 2 O/CuO, ZnO, zinc pyrithione and copper pyrithione, tributyltin, diuron, and irgarol, are not environmentally friendly [198][199][200][201][202]. Due to increasing environmental concerns, many previously used biocides have been, or are going to be banned [203,204], which is stimulating the development of new biocide-releasing coatings. Coating developers have to seek for new environmentally friendly additives or biocides, such as antibiotics, quaternary ammonium ions, and some inorganic ions, compounds or particles [205][206][207][208][209].…”

Organic coatings for marine applications must have great corrosion protection and antifouling performance. This review presents an overview of recent investigations into coating microstructure, corrosion protection performance, antifouling behavior, and evaluation methods, particularly the substrate effect and environmental influence on coating protectiveness, aiming to improve operational practice in the coating industry. The review indicates that the presence of defects in an organic coating is the root cause of the corrosion damage of the coating. The protection performance of a coating system can be enhanced by proper treatment of the substrate and physical modification of the coating. Environmental factors may synergistically accelerate the coating degradation. The long-term protection performance of a coating system is extremely difficult to predict without coating defect information. Non-fouling coating and self-repairing coatings may be promising antifouling approaches. Based on the review, some important research topics are suggested, such as the exploration of rapid evaluation methods, the development of long-term cost-effective antifouling coatings in real marine environments.
