This article examines several federal and state laws, such as the Worker Protection Standards and the Florida Pesticide Law, to determine whether the goals of these laws are being achieved in the State of Florida. A survey based on questions pertaining to various laws was used to gather data on farm workers in three South Florida counties. Face–to–face interviews were conducted with farm workers in Palm Beach and Indian River counties, Florida, in 1997 and in Collier County, Florida, in 1999.
Overall, the findings indicate that farm workers in South Florida have been exposed to pesticides through direct or indirect spraying. The findings of the study reveal that federal and state laws—currently in place to protect the workers from pesticide exposure—are not effectively implemented, and farm workers are uninformed of the laws that exist to protect them from pesticide exposure.
The study concludes with policy recommendations that will improve the implementation and enforcement of the current laws, which are designed to protect farm workers from pesticide exposure. 相似文献

Mitochondrial DNA (mtDNA) examinations play an important role in criminal investigations, identification of victims of mass disasters, and association of unidentified remains with family members. Typically, HV1 and HV2 are amplified via polymerase chain reaction (PCR) followed by fluorescent sequencing. While this method produces the highest level of resolution, it is labor intensive and unable to distinguish components of a mixture. Previously, an electrospray-ionization mass spectrometry (ESI-MS) method was described to determine the base composition profile of enzymatically digested PCR amplified fragments derived from the HV1 and HV2 regions. Advantages of ESI-MS compared to sequencing include speed of analysis, automation, and increased sensitivity, while retaining a high degree of resolution. Here, we report the next generation of this method in which a base composition profile is determined from 24 overlapping PCR reactions. Because ESI-MS provides the relative abundance of each component present, this method allows for the quantitative typing of mixtures. This ESI-MS method does not rely on a priori knowledge of variable sites, allowing the capture of private mutations and individual-specific variation. Due to the multiplex design, automation, speed of analysis, and ability to interrogate mixtures, this method provides a powerful and rapid tool for forensic mtDNA examinations. 相似文献

Mounting evidence documents the extraordinary toll on human health resulting from the consumption of unhealthy food products and physical inactivity. In response to America's growing obesity problem, local policymakers have been looking for legal strategies that can be adopted in their communities to encourage healthful behaviors. In order to provide practical tools to policymakers, this article examines four possible venues for local policy change to improve the health of a community: (1) the school environment (2) the built environment (3) community facilities and (4) the point of sale environment. Finally, the article examines the use of taxes or fees as a means of paying for nutrition policy work as well as potentially reducing the consumption of unhealthy products. This article illustrates that local laws and policies can be a valuable tool in changing a community's environment in order to improve nutritional options and increase opportunities for physical activity. 相似文献
