“…Plasticizers enable the fabrication of a wide variety of plastics, and they have found multiple applications in areas such as the automobile industry, medical products, and commodities. The production of plasticizers has reached 100,000,000 t/year, as a result of the great demand by the plastic industry (Yan et al 2010). …”

Technological, agricultural, and medical advances have improved the lifestyle of humankind. However, these advances have caused new problems that affect the environment and future generations. Emerging contaminants display properties such as low degradation potential and environmental persistence. In addition, most contaminants are lipophilic, which culminates in high bioaccumulation. The disposal of pharmaceuticals and personal care products into the environment underlies microbial and bacterial resistance. Plasticizers change several characteristics of industrialized materials, such as flexibility, but they are potentially carcinogenic and disrupt the endocrine system. Pesticides prevent the propagation of numerous kinds of pests; nevertheless, they exert neurotoxic and mutagenic effects, and they impact the environment negatively. Addition of flame retardants to a number of materials prevents flame propagation; however, after their release into the environment, these chemicals may bioaccumulate in organisms and disrupt the endocrine system, too. Surfactants can change the surface and interfacial properties of liquids, but their presence in the environment can interfere with countless enzymes and can even impair the endocrine system of various organisms and induce the feminization of species. Hence, gaining knowledge about emerging contaminants is increasingly important to minimize future damage and enable proper monitoring of each class of compounds in the environment which will help to improve legislation on this matter.

A. O. Debrot, J.E.Tamis, D. de Haan, M. Scheidat, J.T. van der Wal, 2017 was formally established on September 2, 2015. It is currently composed of two sectors: one surrounding Saba and the Saba Bank and one covering the EEZ waters of Bonaire. In order to help establish an effective cetacean conservation management plan for the Saba and Saba Bank sector of the sanctuary we here review the main marine mammal threats, help identify main management goals and make both governance and management recommendations based both on stakeholder interviews and a management review of functioning marine mammal sanctuaries in the WesternAtlantic.There are 8 species of marine mammals known to occur in the windward Dutch Caribbean YarariSanctuary. The sanctuary has relatively low levels of human activity. Based on our review, cumulative contaminant impacts -such as oil contamination originating from St. Eustatius -are potentially highest, followed by collision impacts due to the relatively high level of shipping traffic. Other factors such as, fishery entanglement, bycatch-impacts and marine debris impacts are likely low compared to many areas directly outside the sanctuary. While whale & dolphin watching impacts are still probably negligible, the impacts of anthropogenic noise, climate-change impacts and cumulative impacts still remain unknown but are potentially high.Five main clusters of interrelated goals and objectives were identified based on expert and management stakeholder interviews. The most essential proximate goal for management should be to establish a minimum structural level of institutional capacity. Under the reigning conditions of resource limitation, the next key goal should be to establish effective collaboration towards jointly achieving the higher management goals and objectives.Based on our review of species, threats, operations of other sanctuaries and expert and stakeholder input we list 23 priority recommendations and action points towards implementation of cetacean conservation for the Saba and Saba Bank Yarari sector. Governance• Use the Saba Bank Management Unit (SMBU) governance model for Yarari management implementation.• Consider merging Yarari tasks into the SMBU to effectuate resource pooling and prevent management fragmentation. Legal resources• Design and implement a simple legal mandate for Yarari management.• Copy and implement international legal guidelines for whale watching.• Revise the Fishery Framework Act BES (Vissery Visserijwet besluit BES) or draft a Decree (Regeling) under the Nature Conservation Framework Act BES (Wet Grondslagen Natuurbeheer en-bescherming, WGN) to forbid all forms of pelagic (not benthic) longline and purse seine fishing in Yarari waters.• Devise and implement legal measures and guidelines to safeguard Yarari from anthropogenic noise pollution. Finances• Based on the review of functioning sanctuaries, and current stressor levels, a basic annual budget of US$ 150 K will be sufficient to implement satisfactory marine mammal conservation.• Focus expenditures on mana...

“…One of the major difficulties regarding the assessment of nanomaterials toxicity in terrestrial ecosystem is related to their aggregation phenomena. Aggregation processes are dependent on the particle features (size, surface area, and intrinsic magnetic moment) and also can be influenced by the environmental characteristics, including pH, ionic strength, and organic matter contents (Klaine et al 2008;Yan et al 2010). Overall, there is a lack of information about the behavior, transport, and fate of nanomaterials through soil profile (Yan et al 2010).…”

In the last few years, several nanomaterials with unique physicochemical properties have been developing. Specially, nano-sized materials such as silver and zinc nanoparticles, carbon nanotubes, and graphene oxide have been attracting great attention due to their potential as novel antimicrobial agents. Worldwide, the constant and indiscriminate use of conventional antibiotics has been responsible for the development of several resistant microbial species. In this context, there is a real and increasing demand for new antimicrobial agents. Nanomaterials offer several benefits due to their small size (high aspect volume/ area) that provides to nanoparticles great ability to get through physical barriers such as membranes and cellular walls. Henceforth, the aim of this present chapter is to discuss the toxicological aspects of nanomaterials to microorganisms, describing the methods to evaluate their antimicrobial activity and highlighting their implications on the microbial communities of soil and water environments. We also stress the main industrial applications of antimicrobial-engineered nanomaterials.
