... There is an additional step described in the protocol (5) that integrates (i) the quality of the evidence (Section 2.10) with other elements, including (ii) direction of effect, (iii) confidence in the effect and (iv) other compelling attributes of the data that may influence certainty, allowing for an overall rating of the strength of the body of evidence of "sufficient evidence of harmfulness", "limited evidence of harmfulness", "inadequate evidence of harmfulness" or "evidence of lack of harmfulness" based on human evidence ( Table 6). The approach to evaluate only the human evidence has been applied in previous systematic reviews (76,82) and verified by the United States National Academy of Sciences (91). The approach also provides two steps that integrate Bradford-Hill criteria (evaluating both the quality and then the overall strength of the evidence). ...

Many people exposed to noise are additionally exposed to toluene as a hazardous and harmful chemical substance; consequently, they are exposed to these factors simultaneously at various wood, chemical, plastic and pharmaceutical industries (Schäper et al., 2008;Board, 2017). While some studies have focused on sexual or endocrine changes induced by non-simultaneous exposure to noise or toluene, no study has been performed on the simultaneous exposure to noise and toluene as well as its effects on the sexual and endocrine systems. ...
... At approximately the same time, ENP was established, and the C&SF Project was created to manage canalization and various constructions to drain and control flooding and create an environment suitable for human settlement, agriculture, and economic development (Davis and Ogden 1994;Ogden 2008). The results of canalization led to the now severely degraded wetland habitats across South Florida (McVoy et al. 2011;Trexler et al. 2003;Hinrichsen 1995). The development impacts of the C&SF Project beginning in the late 1940s led to the creation of the Local Government Comprehensive Planning Bill of 1974(Carter 1974 and the current Comprehensive Everglades Restoration Plan (CERP) of 2000. ...
... Public concerns about biotechnology reflect risk perceptions and distrust in regulatory agencies' capacity and competence to address potential threats to public welfare. 84,85 Nonetheless, excessive oversight of biotechnologies can increase the public's vulnerability to biotechnologies that pose a great threat to public welfare if regulatory resources are improperly expended on governing low risk biotechnologies. It can also stifle the pace of innovation by encouraging biotech developers to create imitation biotechnologies to avoid significant upfront product development and marketing costs, and delay the commercialization of novel biotechnologies if biotech developers must prove their biotechnologies are optimally safe through a prolonged and costly regulatory review process. ...
