This characteristic has promoted dispersed automobile-dependent development patterns (Transportation Research Board, 2009) with consequences for population density, land use mix, and walkability (Richardson, 2004), all of which may have health implications. Factors in the social environment that are important to health include those related to safety, violence, and social disorder in general, and more specific factors related to the type, quality, and stability of social connections, including social participation, social cohesion, social capital, and the collective efficacy of the neighborhood (or work) environment (Ahern and Galea, 2011).6 Social participation and integration in the immediate social environment (e.g., school, work, neighborhood) appear to be important to both mental and physical health (DeSilva et al., 2005). Homicides, Violence, Drug-Related Deaths, and HIV Risk.

As noted above, land use patterns and transportation systems differ starkly between the United States and other high-income countries (Richardson and Bae, 2004; Transportation Research Board, 2009). However, cross-national comparisons of workplace safety, other occupational health characteristics, labor market patterns, and work-related policies were beyond the scope of the panel’s review. Halophiles, which require a NaCl concentration above 0.2 M, take in both potassium and chloride ions as a way to offset the effects of the hypertonic environment that they live in. Importantly, these various features of the physical environment may act synergistically, reinforcing their effects and creating an “obesogenic” environment that affects all U.S. residents, at least to some extent. These patterns are present across countries and across regions within countries, as well as at smaller scales, such as across urban neighborhoods (Center on Human Needs, 2012b; Kawachi and Subramanian, 2007). Many European countries have strong antisprawl and pro-urban centralization policies that may contribute to environments that encourage walking and physical activity as part of daily life (Richardson and Bae, 2004).13. International comparisons of the social environment are complicated by difficulties in obtaining comparable measures of social environments. A physical environment that promotes and incentivizes automobile transportation also reinforces social norms regarding travel, which complicates efforts to modify the patterns. The public health concern has lead Scottish researchers to develop a list of environmental factors that may contribute to the risk of developing dementia. Exactly why is Environmental Health Essential? Polar Ice Caps. How do microbes differ in their response to pH? While a business can control some factors, such as vehicles and transportation, it can't control those forces that exist within the infrastructure (including the transportation network of roads and railroads). More. OpenStax CNX. Physical working conditions (e.g., exposure to dangerous substances, such as lead, asbestos, mercury), as well as physical demands (e.g., carrying heavy loads), human factors, and ergonomic problems can affect the health and safety of employees.
